1993 FORD MONDEO timing belt

contamination with oil or coolant. Renew the
belt if there is the slightest doubt about its
condition. As a safety measure, the belt must
be renewed as a matter of course at the
intervals given in Chapter 1; if its history is
unknown, the belt should be renewed
irrespective of its apparent condition
whenever the engine is overhauled. Similarly,
check the tensioner spring (where fitted),
renewing it if there is any doubt about its
condition. Check also the toothed pulleys for
signs of wear or damage, and ensure that the
tensioner and guide pulleys rotate smoothly
on their bearings; renew any worn or
damaged components. If signs of oil or
coolant contamination are found, trace the
source of the leak and rectify it, then wash
down the engine timing belt area and related
components, to remove all traces of oil or
coolant.
17On reassembly, temporarily refit the
crankshaft pulley, to check that the pulley
notches and sump rib are aligned as
described in paragraph 8 above, then ensure
that both camshafts are aligned at TDC by
the special tool (paragraph 10). If the engine
is being reassembled after major dismantling,
both camshaft toothed pulleys should be free
to rotate on their respective camshafts; if the
timing belt alone is being renewed, both
pulleys should still be securely fastened.
18A holding tool will be required to prevent
the camshaft toothed pulleys from rotating
while their bolts are slackened and
retightened; either obtain Ford service tool15-030A, or fabricate a substitute as follows.
Find two lengths of steel strip, one
approximately 600 mm long and the other
about 200 mm, and three bolts with nuts and
washers; one nut and bolt forming the pivot of
a forked tool, with the remaining nuts and
bolts at the tips of the “forks”, to engage with
the pulley spokes as shown in the
accompanying illustrations. Note:Do not use
the camshaft aligning tool (whether genuine
Ford or not) to prevent rotation while the
camshaft toothed pulley bolts are slackened
or tightened; the risk of damage to the
camshaft concerned and to the cylinder head
is far too great. Use only a forked holding tool
applied directly to the pulleys, as described.
19If it is being fitted for the first time, screw
the timing belt tensioner spring retaining pin
into the cylinder head, tightening it to the
specified torque wrench setting. Unbolt the
tensioner, hook the spring on to the pin and
the tensioner backplate, then refit the
tensioner, engaging its backplate on the
locating peg (see illustrations).
20In all cases, slacken the tensioner bolt (if
necessary), and use an Allen key inserted into
its centre to rotate the tensioner clockwise as
far as possible against spring tension, then
retighten the bolt to secure the tensioner (see
illustration).
21Fit the timing belt; if the original is being
refitted, ensure that the marks and notes
made on removal are followed, so that the
belt is refitted the same way round, and to run
in the same direction. Starting at thecrankshaft toothed pulley, work anti-
clockwise around the camshaft toothed
pulleys and tensioner, finishing off at the rear
guide pulley. The front run, between the
crankshaft and the exhaust camshaft toothed
pulleys, mustbe kept taut, without altering
the position either of the crankshaft or of the
camshaft(s) - if necessary, the position of the
camshaft toothed pulleys can be altered by
rotating each on its camshaft (which remains
fixed by the aligning tool). Where the pulley is
still fastened, use the holding tool described
in paragraph 18 above to prevent the pulley
from rotating while its retaining bolt is
slackened - the pulley can then be rotated on
the camshaft until the belt will slip into place;
retighten the pulley bolt.
22When the belt is in place, slacken the
tensioner bolt gently until the spring pulls the
tensioner against the belt; the tensioner
should be retained correctly against the
timing belt inner shield and cylinder head, but
must be just free to respond to changes in
belt tension (see illustration).
23Tighten both camshaft toothed pulley
bolts (or check that they are tight, as
applicable) and remove the camshaft aligning
tool. Temporarily refit the crankshaft pulley,
and rotate the crankshaft through two full
turns clockwise to settle and tension the
timing belt, returning the crankshaft (pulley
notches) to the position described in
paragraph 8 above. Refit the camshaft
aligning tool; it should slip into place as
described in paragraph 10. If all is well,
proceed to paragraph 26 below.
24If one camshaft is only just out of line, fit
the forked holding tool to its toothed pulley,
adjust its position as required, and check that
any slack created has been taken up by the
tensioner; rotate the crankshaft through two
further turns clockwise, and refit the camshaft
aligning tool to check that it now fits as it
should. If all is well, proceed to paragraph 26
below.
25If either camshaft is significantly out of
line, use the holding tool described in
paragraph 18 above to prevent its pulley from
rotating while its retaining bolt is slackened -
the camshaft can then be rotated (gently and
carefully, using an open-ended spanner) until

the camshaft aligning tool will slip into place;
take care not to disturb the relationship of the
pulley to the timing belt. Without disturbing
the pulley’s new position on the camshaft,
tighten the pulley bolt to its specified torque
wrench setting (see illustration). Remove the
camshaft aligning tool, rotate the crankshaft
through two further turns clockwise and refit
the tool to check that it now fits as it should.
26When the timing belt has been settled at
its correct tension, and the camshaft aligning
tool fits correctly when the crankshaft pulley
notches are exactly aligned, tighten the
tensioner bolt to its specified torque wrench
setting (see illustration). Fitting the forked
holding tool to the spokes of each pulley in
turn, check that the pulley bolts are tightened
to their specified torque wrench setting.
Remove the camshaft aligning tool, rotate the
crankshaft through two further turns
clockwise, and refit the tool to make a final
check that it fits as it should.
27The remainder of the reassembly
procedure is the reverse of removal, noting
the following points:
(a) Tighten all fasteners to the torque wrench
settings specified.
(b) When reassembling the
engine/transmission right-hand mounting,
renew the self-locking nuts, and do not
allow the mounting to twist as the middle
two of the bracket’s six nuts are
tightened.
Tensioner
Note:If the tensioner is being removed for the
first time since the vehicle left the factory, a
tensioner spring and retaining pin must be
obtained for fitting on reassembly.
1While it is possible to reach the tensioner
once the timing belt upper and middle covers
only have been removed (see Section 9), the
whole procedure outlined below must be
followed, to ensure that the valve timing is
correctly reset once the belt’s tension has
been disturbed.
2Release the tension from the timing belt as
described in Section 10, paragraphs 1 to 14.
3Unscrew the tensioner bolt and withdraw
the tensioner, unhooking the spring, if fitted
(see illustration). Check the tensioner and
spring as described in paragraph 16 of
Section 10.
4On reassembly, if it is being fitted for the
first time, screw the timing belt tensioner
spring retaining pin into the cylinder head,
tightening it to the specified torque wrench
setting. Hook the spring onto the pin and the
tensioner backplate, then refit the tensioner,
engaging its backplate on the locating peg.
5Use an Allen key inserted into its centre to
rotate the tensioner clockwise as far as
possible against spring tension, then tighten
the bolt to secure the tensioner.
6Reassemble, checking the camshaft
alignment (valve timing) and setting the timing
belt tension, as described in paragraphs 22 to
27 of Section 10.
Camshaft and crankshaft toothed
pulleys
7While it may be possible to remove any of
these pulleys once their respective covers
have been removed, the complete timing belt
removal/refitting procedure (see Section 10)
must be followed, to ensure that the valve
timing is correctly reset once the belt’s
tension has been disturbed.8With the timing belt removed, the camshaft
toothed pulleys can be detached once their
retaining bolts have been unscrewed as
described in paragraphs 18 and 21 of Section
10. The crankshaft toothed pulley can be
pulled off the end of the crankshaft once the
crankshaft (grooved) pulley and the timing
belt have been removed. Note the “FRONT”
marking identifying the pulley’s outboard
face, and the thrustwasher behind it; note
which way round the thrustwasher is fitted
(see illustration). Note the pulley-locating
Woodruff key; if this is loose, it should be
removed for safe storage with the pulley.
9Check the pulleys as described in
paragraph 16 of Section 10.
10Refitting is the reverse of the removal
procedure.
Timing belt guide pulleys
11Remove the timing belt covers (see
Section 9).
12Unbolt and withdraw the pulley(s); check
their condition as described in paragraph 16
of Section 10.
13Refitting is the reverse of the removal
procedure; tighten the pulley bolts to the
specified torque wrench setting (see
illustration).
Note:While it is possible to reach either oil
seal, once the respective toothed pulley has
been removed (see Section 11) to allow the
seal to be prised out, this procedure is not
recommended. Not only are the seals very
soft, making this difficult to do without risk of
damage to the seal housing, but it would be
very difficult to ensure that the valve timing
and the timing belt’s tension, once disturbed,
are correctly reset. Owners are advised to
follow the whole procedure outlined below.
1Release the tension from the timing belt as
described in Section 10, paragraphs 1 to 14.
Note:If the timing belt is found to be
contaminated by oil, remove it completely as
described, then renew the oil seal (see below).

related components, to remove all traces of
oil. Fit a new belt on reassembly.
2If the timing belt is still clean, slip it off the
toothed pulley, taking care not to twist it too
sharply; use the fingers only to handle the
belt. Do notrotate the crankshaft until the
timing belt is refitted. Cover the belt, and
secure it so that it is clear of the working area
and cannot slip off the remaining toothed
pulley.
3Unfasten the pulley bolt and withdraw the
pulley (see Section 11).
4Unbolt the camshaft right-hand bearing
cap, and withdraw the defective oil seal.
Clean the seal housing, and polish off any
burrs or raised edges, which may have
caused the seal to fail in the first place.
5To fit a new seal, Ford recommend the use
of their service tool 21-009B, with a bolt
(10 mm thread size, 70 mm long) and a
washer, to draw the seal into place when the
camshaft bearing cap is bolted down; a
substitute can be made using a suitable
socket (see illustration). Grease the seal lips
and periphery to ease installation, and draw
the seal into place until it is flush with the
housing/bearing cap outer edge. Refit the
bearing cap, using sealant and tightening the
cap bolts as described in Section 13.
6For most owners, the simplest answer will
be to grease the seal lips, and to slide it on to
the camshaft (until it is flush with thehousing’s outer edge). Refit the bearing cap,
using sealant and tightening the cap bolts as
described in Section 13 (see illustration).
Take care to ensure that the seal remains
absolutely square in its housing, and is not
distorted as the cap is tightened down.
7Refit the pulley to the camshaft, tightening
the retaining bolt loosely, then slip the timing
belt back onto the pulley (refer to para-
graphs 18 and 21 of Section 10) and tighten
the bolt securely.
8The remainder of the reassembly
procedure, including checking the camshaft
alignment (valve timing) and setting the timing
belt tension, is as described in paragraphs 22
to 27 of Section 10.
Removal
1Release the tension from the timing belt as
described in Section 10, paragraphs 1 to 14.
2Either remove the timing belt completely
(Section 10, paragraphs 15 and 16) or slip it
off the camshaft toothed pulleys, taking care
not to twist it too sharply; use the fingers only
to handle the belt. Cover the belt, and secure
it so that it is clear of the working area. Do not
rotate the crankshaft until the timing belt is
refitted.3Unfasten the pulley bolts as described in
Section 10, paragraphs 18 and 21, and
withdraw the pulleys; while both are the same
and could be interchanged, it is good working
practice to mark them so that each is refitted
only to its original location (see illustration).
4Working in the sequence shown, slacken
progressively, by half a turn at a time, the
camshaft bearing cap bolts (see illustration).
Work only as described, to release gradually
and evenly the pressure of the valve springs
on the caps.
5Withdraw the caps, noting their markings
and the presence of the locating dowels, then
remove the camshafts and withdraw their oil
seals. The inlet camshaft can be identified by
the reference lobe for the camshaft position
sensor; therefore, there is no need to mark
the camshafts (see illustrations).
6Obtain sixteen small, clean containers, and
number them 1 to 16. Using a rubber sucker,
withdraw each hydraulic tappet in turn, invert
it to prevent oil loss, and place it in its
respective container, which should then be
filled with clean engine oil (see illustrations).
Do not interchange the hydraulic tappets, or
the rate of wear will be much increased. Do
not allow them to lose oil, or they will take a
long time to refill on restarting the engine,
resulting in incorrect valve clearances.

23If using Ford’s recommended procedure,
fit new oil seals to the camshafts as
described in paragraph 5 of Section 12.
24Using the marks and notes made on
dismantling to ensure that each is refitted to
its original camshaft, refit the toothed pulleys
to the camshafts, tightening the retaining
bolts loosely (see illustration). Slip the timing
belt back onto the pulleys (refer to para-
graph 21 of Section 10) and tighten the bolts
securely - use the forked holding tool
described in paragraph 18 of Section 10.
25The remainder of the reassembly
procedure, including checking the camshaft
alignment (valve timing) and setting the timing
belt tension, is as described in paragraphs 17
to 27 of Section 10.
Removal
Note:The following text assumes that the
cylinder head will be removed with both inlet
and exhaust manifolds attached; this
simplifies the procedure, but makes it a bulky
and heavy assembly to handle - an engine
hoist will be required, to prevent the risk of
injury, and to prevent damage to any delicate
components as the assembly is removed and
refitted. If it is wished first to remove the
manifolds, proceed as described in Sections
6 and 7 of this Chapter; amend the following
procedure accordingly.1Relieve the fuel system pressure (see
Chapter 4).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Whenever you disconnect any vacuum
lines, coolant and emissions hoses, wiring
loom connectors, earth straps and fuel lines
as part of the following procedure, always
label them clearly, so that they can be
correctly reassembled.
4Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).
5Equalise the pressure in the fuel tank by
removing the filler cap, then undo the fuel
feed and return lines connecting the engine to
the chassis (see Chapter 4). Plug or cap all
open fittings.
6Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -where fitted, disconnect also the cruise control
actuator cable (see Chapter 12). Secure the
cable(s) clear of the engine/transmission.
7Unbolt the power steering high-pressure
pipe from the cylinder head rear support
plate/engine lifting eye, and from the front
support plate/pump bracket. Releasing its
wire clip, unplug the power steering pressure
switch electrical connector, then unbolt the
earth lead from the cylinder head rear support
plate/engine lifting eye.
8Remove the three screws securing the
wiring “rail” to the rear of the manifold.
Releasing its wire clip, unplug the large
electrical connector (next to the fuel pressure
regulator) to disconnect the engine wiring from
the main loom (see illustration). Unplug the
electrical connectors on each side of the
ignition coil, and the single connector from
beneath the front of the thermostat housing, to
disconnect the coil and coolant temperature
gauge sender wiring (see illustration).
9Marking or labelling them as they are
unplugged, disconnect the vacuum hoses as
follows:
(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose (see Chapter 9 for details).
(d) Disconnect all vacuum hoses from the
Exhaust Gas Recirculation system
components - one from the EGR valve
and two from the EGR pipe. (Note that
these last two are of different sizes, as are
their pipe stubs, so that they can only be
connected the correct way round.)
10Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow the
upper part to be withdrawn. Either remove the
dipstick and tube, or swing them out of the way.
11Unscrew the single bolt securing the
pulse-air filter housing to the engine/
transmission front mounting bracket, then
disconnect its vacuum hose.
12Drain the cooling system (see Chapter 1).
13Disconnect all coolant hoses from the
thermostat housing (see illustration).

14Unscrew the two nuts to disconnect the
exhaust system front downpipe from the
manifold (Chapter 4); disconnect the oxygen
sensor wiring, so that it is not strained by the
weight of the exhaust system.
15Remove the auxiliary drivebelt (see
Chapter 1).
16Support the weight of the
engine/transmission using a trolley jack, with
a wooden spacer to prevent damage to the
sump.
17Unscrew the six nuts securing the
engine/transmission right-hand mounting
bracket, then withdraw the bracket. Unbolt
the auxiliary drivebelt’s idler pulley (see
illustration).
18Unbolt the cylinder head front and rear
support plates (see illustrations).
19Remove the timing belt and both
camshafts (see Sections 10 and 13); if the
cylinder head is to be dismantled, withdraw
the hydraulic tappets.
20Remove the timing belt inner shield (see
Section 9).
21Working in the reverseof the sequence
shown in illustration 14.32C, slacken the ten
cylinder head bolts progressively and by one
turn at a time; a Torx key (TX 55 size) will be
required. Remove each bolt in turn, and
ensure that new replacements are obtained
for reassembly; these bolts are subjected to
severe stresses and so must be renewed,
regardless of their apparent condition,
whenever they are disturbed.22Lift the cylinder head away; use
assistance if possible, as it is a heavy
assembly (see illustration). Remove the
gasket, noting the two dowels, and discard it.
Refitting
23The mating faces of the cylinder head and
cylinder block must be perfectly clean before
refitting the head. Use a hard plastic or wood
scraper to remove all traces of gasket and
carbon; also clean the piston crowns. Take
particular care, as the soft aluminium alloy is
easily damaged. Also, make sure that the
carbon is not allowed to enter the oil and
water passages - this is particularly important
for the lubrication system, as carbon could
block the oil supply to any of the engine’s
components. Using adhesive tape and paper,
seal the water, oil and bolt holes in the
cylinder block. Clean all the pistons in the
same way.24Check the mating surfaces of the cylinder
block and the cylinder head for nicks, deep
scratches and other damage. If slight, they
may be removed carefully with a file, but if
excessive, machining may be the only
alternative to renewal.
25If warpage of the cylinder head gasket
surface is suspected, use a straight edge to
check it for distortion. Refer to Part B of this
Chapter, Section 7, if necessary.
26Wipe clean the mating surfaces of the
cylinder head and cylinder block. Check that
the two locating dowels are in position in the
cylinder block, and that all cylinder head bolt
holes are free from oil.
27Position a new gasket over the dowels on
the cylinder block surface, so that the
“TOP/OBEN” mark is uppermost, and the
tooth (or teeth, according to engine size)
protruding from one edge point to the front of
the vehicle (see illustration).
28Temporarily refit the crankshaft pulley,
and rotate the crankshaft anti-clockwise so
that No 1 cylinder’s piston is lowered to
approximately 20 mm before TDC, thus
avoiding any risk of valve/piston contact and
damage during reassembly.
29As the cylinder head is such a heavy and
awkward assembly to refit with manifolds, it is
helpful to make up a pair of guide studs from
two 10 mm (thread size) studs approximately
90 mm long, with a screwdriver slot cut in one
end - two old cylinder head bolts with their
heads cut off would make a good starting
point. Screw these guide studs, screwdriver
slot upwards to permit removal, into the bolt
holes at diagonally-opposite corners of the
cylinder block surface (or into those where
the locating dowels are fitted, as shown);
ensure that approximately 70 mm of stud
protrudes above the gasket.
30Refit the cylinder head, sliding it down the
guide studs (if used) and locating it on the
dowels (see illustration). Unscrew the guide
studs (if used) when the head is in place.
31Fit the new cylinder head bolts dry (do not
oiltheir threads); carefully enter each into its
hole and screw it in, by hand only, until finger-
tight.
32Working progressively and in the
sequence shown, use first a torque wrench,

then an ordinary socket extension bar and an
angle gauge, to tighten the cylinder head
bolts in the stages given in the Specifications
Section of this Chapter (see illustrations).
Note:Once tightened correctly, following this
procedure, the cylinder head bolts do not
require check-tightening, and must notbe re-
torqued.
33Refit the hydraulic tappets (if removed),
the camshafts, their oil seals and pulleys (see
Sections 10, 11, 12 and 13, as appropriate).
Temporarily refit the crankshaft pulley, and
rotate the crankshaft clockwise to return the
pulley notches to the position described in
paragraph 8 of Section 10.
34Refit the timing belt and covers, checking
the camshaft alignment (valve timing) and
setting the timing belt tension, as described in
Section 10.
35The remainder of reassembly is the
reverse of the removal procedure, noting the
following points:
(a) Tighten all fasteners to the torque wrench
settings specified.
(b) When reassembling the
engine/transmission right-hand mounting,
renew the self-locking nuts, and do not
allow the mounting to twist as the middle
two of the bracket’s six nuts are
tightened.
(c) Refill the cooling system, and top-up the
engine oil.
(d) Check all disturbed joints for signs of oil
or coolant leakage, once the engine has
been restarted and warmed-up to normal
operating temperature.
Removal
Note:To carry out this task with the
engine/transmission installed in the vehicle
requires the assistance of at least one person,
plus the equipment necessary to raise and
support the front of the vehicle (high enough
that the sump can be withdrawn from
underneath), and to lift and support the
complete engine/transmission unit 2 to 3 inches from its mountings while the vehicle
is raised. Precise details of the procedure will
depend on the equipment available - the
following is typical.
The full procedure outlined below must be
followed, so that the mating surfaces can be
cleaned and prepared to achieve an oil-tight
joint on reassembly, and so that the sump
can be aligned correctly; depending on your
skill and experience, and the tools and
facilities available, it may be that this task can
be carried out only with the engine removed
from the vehicle.
Note that the sump gasket must be
renewed whenever it is disturbed.
1With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
2Drain the engine oil, then clean and refit the
engine oil drain plug, tightening it to the
specified torque wrench setting. Although not
strictly necessary as part of the dismantling
procedure, owners are advised to remove
and discard the oil filter, so that it can be
renewed with the oil (see Chapter 1).
3Drain the cooling system (see Chapter 1).
4Disconnect the radiator bottom hose from
the radiator union and from the (heater)
coolant pipe. Unbolt the coolant pipe from
the sump; if they will prevent sump removal,
disconnect or release the coolant hoses from
the oil cooler unions (where fitted).
5Unscrew the two bolts securing the powersteering system pipes to the right-hand side
of the subframe.
6Unplug the electrical connector(s) to
disconnect the oxygen sensor and, where
fitted, the oil level sensor wiring - unclip the
connectors to release the wiring where
necessary.
7Where the vehicle is fitted with automatic
transmission, trace the fluid cooler lines from
the transmission to the radiator, and release
them from any clips etc, so that they have as
much movement as possible.
8Remove the auxiliary drivebelt cover (see
Chapter 1).
9Unscrew the nuts to disconnect the
exhaust system front downpipe from the
manifold, then either unhook all the system’s
rubber mountings and withdraw the complete
exhaust system from under the vehicle, or
remove only the downpipe/catalytic converter
(see Chapter 4 for details).
10Unscrew the sump-to-transmission bolts,
also any securing the engine/transmission
lower adaptor plate.
11Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).

(d) Fitting the Ford service tool in place of the
front mounting, tighten the
engine/transmission mounting fasteners
to their specified torque wrench settings,
and in the sequence described in Part B
of this Chapter, Section 4, paragraphs 49
and 50.
(e) Refill the cooling system (see Chapter 1).
(f) Refill the engine with oil, remembering
that you are advised to fit a new filter (see
Chapter 1).
(g) Check for signs of oil or coolant leaks
once the engine has been restarted and
warmed-up to normal operating
temperature.
Removal
Note:While this task is theoretically possible
when the engine is in place in the vehicle, in
practice, it requires so much preliminary
dismantling, and is so difficult to carry out due
to the restricted access, that owners are
advised to remove the engine from the vehicle
first. Note, however, that the oil pumppressure relief valve can be removed with the
engine in situ - see paragraph 8.
In addition to the new pump gasket and
other replacement parts required, read
through Section 15, and ensure that the
necessary tools and facilities are available.
1Remove the timing belt (see Section 10).
2Withdraw the crankshaft toothed pulley
and the thrustwasher behind it, noting which
way round the thrustwasher is fitted (see
Section 11).
3Remove the sump (see Section 15).
4Undo the screws securing the oil pump
pick-up/strainer pipe to the pump, then
unscrew the nut and withdraw the oil pump
pick-up/strainer pipe. Discard the gasket.
5Unbolt the pump from the cylinder
block/crankcase (see illustration). Withdraw
and discard the gasket, and remove the
crankshaft right-hand oil seal. Thoroughly
clean and degrease all components,
particularly the mating surfaces of the pump,
the sump, and the cylinder block/crankcase.
Inspection
6Unscrew the Torx screws, and remove the
pump cover plate; noting any identification
marks on the rotors, withdraw the rotors (see
illustration).
7Inspect the rotors for obvious signs of wear
or damage, and renew if necessary; if either
rotor, the pump body, or its cover plate are
scored or damaged, the complete oil pump
assembly must be renewed.
8The oil pressure relief valve can bedismantled, if required, without disturbing the
pump. With the vehicle parked on firm level
ground, apply the handbrake securely and
raise its front end, supporting it securely on
axle stands. Remove the front right-hand
roadwheel and auxiliary drivebelt cover (see
Chapter 1) to provide access to the valve.
9Unscrew the threaded plug, and recover
the valve spring and plunger (see
illustrations). If the plug’s sealing O-ring is
worn or damaged, a new one must be
obtained, to be fitted on reassembly.
10Reassembly is the reverse of the
dismantling procedure; ensure the spring and
valve are refitted the correct way round, and
tighten the threaded plug securely.
Refitting
11The oil pump must be primed on
installation, by pouring clean engine oil into it,
and rotating its inner rotor a few turns.
12Using grease to stick the new gasket in
place on the cylinder block/crankcase, and
rotating the pump’s inner rotor to align with
the flats on the crankshaft, refit the pump and
insert the bolts, tightening them lightly at first
(see illustration).
13Using a suitable straight edge and feeler
gauges, check that the pump is both centred
exactlyaround the crankshaft, and aligned
squarely so that its (sump) mating surface is
exactly the same amount - between 0.3 and
0.8 mm - below that of the cylinder block/
crankcase on each side of the crankshaft
(see illustration). Being careful not to disturb

gear linkage heat shield. Reconnect the
gearchange linkage and transmission support
rods to the transmission, adjusting the linkage
using the marks made on removal (see
Chapter 7, Part A, for details).
56Re-install the remaining components and
fasteners in the reverse order of removal.
57Add coolant, engine oil and transmission
fluids as needed (see Chapter 1).
58Run the engine, and check for proper
operation and the absence of leaks. Shut off
the engine, and recheck the fluid levels.
59Remember that, since the front suspension
subframe and steering gear have been
disturbed, the wheel alignment and steering
angles must be checked fully and carefully as
soon as possible, with any necessary
adjustments being made. This operation is best
carried out by an experienced mechanic, using
proper checking equipment; the vehicle should
therefore be taken to a Ford dealer or similarly-
qualified person for attention.
1It is much easier to dismantle and work on
the engine if it is mounted on a portable engine
stand. These stands can often be hired from a
tool hire shop. Before the engine is mounted
on a stand, the flywheel/driveplate should be
removed (Part A of this Chapter, Section 21)
so that the stand bolts can be tightened into
the end of the cylinder block/crankcase.
2If a stand is not available, it is possible to
dismantle the engine with it mounted on
blocks, on a sturdy workbench or on the floor.
Be extra-careful not to tip or drop the engine
when working without a stand.
3If you are going to obtain a reconditioned
engine, all external components must be
removed first, to be transferred to the
replacement engine (just as they will if you are
doing a complete engine overhaul yourself).
Note:When removing the external
components from the engine, pay close
attention to details that may be helpful or
important during refitting. Note the fitted
position of gaskets, seals, spacers, pins,
washers, bolts and other small items.These
external components include the following:
(a) Alternator and brackets (Chapter 5).
(b) HT leads and spark plugs (Chapter 1).
(c) Thermostat and housing (Chapter 3).
(d) Dipstick tube.
(e) Fuel injection system components
(Chapter 4).
(f) All electrical switches and sensors - refer
to the appropriate Chapter.
(g) Inlet and exhaust manifolds (Part A of this
Chapter).
(h) Oil filter (Chapter 1).
(i) Engine/transmission mounting brackets
(Part A of this Chapter, Section 22).
(j) Flywheel/driveplate (Part A of this
Chapter, Section 21).
4If you are obtaining a “short” engine (whichconsists of the engine cylinder
block/crankcase, crankshaft, pistons and
connecting rods all assembled), then the
cylinder head, sump, oil pump, and timing belt
will have to be removed also.
5If you are planning a complete overhaul, the
engine can be dismantled and the internal
components removed in the following order.
(a) Inlet and exhaust manifolds (Part A of this
Chapter).
(b) Timing belt, toothed pulleys and
tensioner, and timing belt inner cover
(Part A of this Chapter).
(c) Cylinder head (Part A of this Chapter,
Section 14).
(d) Flywheel/driveplate (Part A of this
Chapter, Section 21).
(e) Sump (Part A of this Chapter, Section 15).
(f) Oil pump (Part A of this Chapter, Sec-
tion 16).
(g) Piston/connecting rod assemblies
(Section 9).
(h) Crankshaft (Section 10).
6Before beginning the dismantling andoverhaul procedures, make sure that you have
all of the correct tools necessary. Refer to the
introductory pages at the beginning of this
manual for further information.
Note:New and reconditioned cylinder heads
are available from the manufacturers, and
from engine overhaul specialists. Due to the
fact that some specialist tools are required for
the dismantling and inspection procedures,
and new components may not be readily
available (refer to Section 1 of this Part), it may
be more practical and economical for the
home mechanic to purchase a reconditioned
head, rather than to dismantle, inspect and
recondition the original head.

tappets (Part A of this Chapter, Section 13),
being careful to store the hydraulic tappets as
described (see illustration).
