Dismantling
1It is best to mount the engine on a
dismantling stand, but if this is not available,
stand the engine on a strong bench at a
comfortable working height. Failing this, it will
have to stripped down on the floor.
2Cleanliness is most important, and if the
engine is dirty, it should be cleaned with
paraffin while keeping it in an upright position.
3Avoid working with the engine directly on a
concrete floor, as grit presents a real source
of trouble.
4As parts are removed, clean them in a
paraffin bath. However, do not immerse parts
with internal oilways in paraffin as it is difficult
to remove, usually requiring a high pressure
hose. Clean oilways with nylon pipe cleaners.
5It is advisable to have suitable containers
available to hold small items according to
their use, as this will help when reassembling
the engine and also prevent possible losses.
6Always obtain a complete set of new
gaskets for use during engine reassembly, but
retain the old gaskets with a view to using
them as a pattern to make a replacement if a
new one is not available.
7Where possible, refit securing nuts, bolts
and washers to their locations after removing
the relevant components. This will help to
protect the threads and will also prevent
possible losses.
8Retain unserviceable components in order
to compare them with the new components
supplied.
9A suitable Torx socket will be required to
remove the oil pump cover securing screws.
10Before dismantling the main engine
components, the following externally mounted
ancillary components can be removed:
Inlet manifold and carburettor
Exhaust manifold
Fuel pump and operating pushrod
Alternator
Spark plugs
Oil pressure warning lamp switch (see
illustration)
Oil filter
Dipstick
Engine mounting brackets
Clutch
Alternator mounting bracket
Crankshaft speed/position sensor
Engine lifting brackets
Examination and renovation
11Refer to Section 18 in Chapter 2, PartA.
Reassembly
12To ensure maximum life with minimum
trouble from a rebuilt engine, not only must
everything be correctly assembled, but it mustalso be spotlessly clean. All oilways must be
clear, and locking washers and spring
washers must be fitted where indicated. Oil all
bearings and other working surfaces
thoroughly with engine oil during assembly.
13Before assembly begins, renew any bolts
or studs with damaged threads.
14Gather together a torque wrench, oil can,
clean rag, and a set of engine gaskets and oil
seals, together with a new oil filter.
15If they have been removed, new cylinder
head bolts, big-end bolts/nuts and new
flywheel bolts will be required.
16After reassembling the main engine
components, refer to paragraph 10 and refit
the ancillary components listed. Delicate
items such as the alternator may be left until
after the engine has been refitted.

20Refer to paragraphs 12 to 16 but note that
new rocker arm nuts will be required, if they
have been removed.
Note: The belt tension should be checked
using Ford special tool No 21-113 after
refitting. A suitable puller may be required to
remove the sprockets. If the camshaft
sprocket is removed, a new retaining bolt
must be used on refitting, and suitable sealant
(Loctite 74 or 274, or Omnifit 30M blue) will be
required to coat the bolt threads.
1.8 litre (R2A type)
Removal
1If the engine is in the vehicle, carry out the
following operations:
a)Disconnect the battery negative lead
b)Remove the alternator drivebelt
c)Remove the distributor cap, rotor arm and
housing
d)Disconnect the wiring plug from the
crankshaft speed/position sensor
e)Unclip the coolant hoses from the timing
cover, and position them across the top
of the camshaft cover out of the way
f)If desired for improved access, remove
the fan shroud and cooling fan assembly,
although this is not essential
2Slacken the crankshaft pulley bolt. Prevent
the crankshaft from turning by engaging top
gear (manual gearbox only) and having an
assistant apply the brake pedal hard, or by
removing the starter motor and jamming the
ring gear teeth with a lever.
3Remove the bolt and washer and withdraw
the pulley (see illustration). If the pulley will
not come off easily, refit the bolt part way and
use a puller, but take care not to damage the
sensor toothed disc.

1.8 litre (R2A)

16Where applicable, refit the timing belt
tensioner and coolant pump, locate the timing
belt backplate over the studs, then fit the
camshaft sprocket and the distributor rotor
shaft.
17The camshaft sprocket bolt must be
coated with sealant before installation. The
manufacturers recommend Loctite 74 or 274,
or Omnifit 30M blue. With the sealant applied,
insert the bolt, hold the camshaft sprocket
stationary as during removal, and tighten the
bolt to the specified torque (see illustration).
18Refit the thrustwasher with the convex
side facing forwards, and refit the Woodruff
key, then refit the crankshaft sprocket with the
“FRONT” mark facing forwards.
19Fit the timing belt over the crankshaft
sprocket, but do not engage it with the other
sprockets yet. Be careful not to kink the belt,
and if the old belt is being refitted, observe the
previously noted running direction.20Make sure that the TDC pointer on the
camshaft sprocket is still aligned with the dot
on the cylinder head front face.
21Check that the TDC lug on the crankshaft
sprocket is still in line with the notch in the oil
pump flange. If necessary, refit the crankshaft
pulley bolt, if not already done, and using a
socket on the bolt, turn the crankshaft by the
shortest possible route to align the lug and
notch.
22Starting at the crankshaft and working in
an anti-clockwise direction, fit the timing belt
over the camshaft sprocket, round the
tensioner roller, and over the coolant pump
sprocket.
23Slacken the tensioner bolts, allow the
tensioner roller to rest against the belt, then
tighten the tensioner bolts.
24Refit the crankshaft pulley bolt, if not
already done, and using a socket on the bolt,
turn the engine through two revolutions in a
clockwise direction (to bring No 1 cylinder
back to TDC), then turn the crankshaft 60º
anti-clockwise (No 1 cylinder at 60º BTDC).
25The belt tension should now be checked
by applying Ford tension gauge, tool No 21-
113 to the longest belt run. Desired gauge
readings are:
Used belt - 4 to 6
New belt - 10 to 11
If the tension gauge is not available, a rough
guide is that the belt tension is correct when
the belt can be twisted 90º in the middle of the
longest run with the fingers using moderate
pressure (see illustration). In this case, the
vehicle should be taken to a Ford dealer so
that the belt tension can be checked using the
special gauge at the earliest opportunity.
26If adjustment of belt tension is necessary,
turn the crankshaft clockwise to bring No 1
cylinder to TDC, then slacken the tensioner
bolts and move the tensioner to increase or
decrease the belt tension. Tighten the
tensioner bolts to the specified torque.
27Turn the crankshaft 90º clockwise past
TDC, then anti-clockwise back to the 60º
BTDC position (No 1 cylinder at 60º BTDC).
Check the belt tension again (see
illustration).28Repeat the procedure given in paragraphs
26 and 27 until the belt tension is correct.
29Refit the timing cover and secure with the
two bolts and nuts. Ensure that the earth tag
and the coolant hose clip are fitted under the
relevant nuts (see illustration).
30Unscrew the crankshaft pulley bolt, then
refit the crankshaft pulley and the bolt and
washer. Tighten the crankshaft pulley bolt to
the specified torque, preventing the
crankshaft from turning as described in
paragraph 2.
31If the engine is in the vehicle, reverse the
operations described in paragraph 1.
1.6 and 1.8 litre (R6A type)
32If the engine is in the vehicle, carry out the
following operations.
a)Disconnect the battery negative lead.
b)Remove the alternator drivebelt.
c)Disconnect the HT leads from the spark
plugs, noting their locations; detach the
HT lead bracket from the camshaft cover,
and position the leads out of the way.
d)Move the coolant hoses from the front of
the timing cover, and position them
across the top of the camshaft cover out
of the way.
e)If desired for improved access, remove
the fan shroud and the cooling fan
assembly, although this is not essential.
33Proceed as described in paragraphs 2 to
30 inclusive, noting the following differences
for the 1.6 litre engine (see illustrations).
a)There is no sensor toothed disc on the
crankshaft pulley.
b)A two-piece timing cover is fitted,
consisting of upper and lower sections,
each secured by two bolts. No earth tag
or coolant hose clip is fitted to the bolts.
c)The TDC datum on the oil pump takes the
form of a lug instead of a notch.
d)There is no distributor rotor shaft fitted to
the camshaft sprocket bolt.
e)There is no timing belt backplate.

4Repeat the procedure given in paragraphs
2 and 3 for the remaining valves, keeping all
components identified for location so that
they can be refitted in their original positions.
Note that the inlet valve springs are fitted with
metal dampers. The damper is an integral part
of the spring and cannot be removed (see
illustration).
Reassembly
5Commence reassembly by lubricating the
valve stems and guides with SAE 80/90
hypoid oil, then insert the valves into their
original guides.
6Refit the spring seats over the valve stems.
7Wrap a thin layer of adhesive tape over the
collet grooves of each valve, then smear the
new oil seals with a little hypoid oil and slide
them down the valve stems onto the spring
seats. Use a suitable metal tube to seat the
seals, then remove the adhesive tape from the
valves (see illustration).
8Working on each valve in turn, fit the valve
spring and cap, then compress the spring
using the valve spring compressor and fit the
split collets to the groove in the valve stem.
Release the compressor and tap the end of
the valve stem with a soft-faced mallet to
settle the components. If the original
components are being refitted, ensure that
they are refitted in their original locations.
9Refit the camshaft.
1.6 and 1.8 litre (R6A type)
10Proceed as described in paragraphs 1 to 9
inclusive, but note that no dampers are fitted
to the inlet valve springs on the 1.6 litre engine.Refer to Section 23, Chapter 2, Part A but
pay particular attention to the note at the
beginning of the Section as all CVH engines
are fitted with hardened valve seats.
Note: A new camshaft oil seal and new rocker
arm securing nuts should be used when
refitting.
1.8 litre (R2A type)
Removal
1Remove the cylinder head.
2Unscrew the securing bolts and remove the
rocker arm guides, rocker arms, and cam
follower guide retainers, then lift out the cam
follower guides and the cam followers. Keep
all components in the correct order so that
each component can be refitted in the original
position if it is to be re-used. It is advisable to
store the cam followers upright in an oil bath
until they are to be refitted. Ensure that the
depth of oil is sufficient to fully cover the cam
followers.
3Prise out the camshaft oil seal, taking care
not to damage the surface of the camshaft. If
necessary use self-tapping screws and a
suitable pair of grips to withdraw the seal.4Unscrew the two securing bolts and
withdraw the camshaft thrustplate from the
front of the cylinder head.
5Carefully withdraw the camshaft from the
front of the cylinder head, taking care not to
damage the bearings. If necessary, loosely
refit the camshaft sprocket and bolt to aid
removal.
Inspection
6Examine the surfaces of the camshaft
journals and lobes, and the cam follower rollers
for wear. If wear is excessive, considerable
noise would have been noticed from the top of
the engine when running, and a new camshaft
and followers must be fitted. It is unlikely that
this level of wear will occur unless a
considerable mileage has been covered. Note
that the cam followers cannot be dismantled
for renewal of individual components.
7Check the camshaft bearings in the cylinder
head for wear. If excessive wear is evident, it
may be possible to have the head machined by
a suitably equipped engineering workshop to
enable a camshaft with oversize bearing
journals to be fitted. The only other course of
action available is renewal of the cylinder head.
8Check the cam follower bores in the
cylinder head for wear. If excessive wear is
evident, the cylinder head must be renewed.
9Check the cam follower oil ports and the oil
holes in the cylinder head for obstructions
(see illustrations).

until they are to be refitted. Ensure that the
depth of oil is sufficient to fully cover the cam
followers.
25Prise out the camshaft oil seal, taking care
not to damage the surface of the camshaft. If
necessary, use self-tapping screws and a
suitable pair of grips to withdraw the seal.
26Unscrew the two securing bolts, and
withdraw the camshaft thrustplate from the
front of the cylinder head.
27Carefully withdraw the camshaft from the
front of the cylinder head, taking care not to
damage the bearings. If necessary, loosely
refit the camshaft sprocket and bolt to aid
removal.
Inspection
28Proceed as described in paragraphs 6 to
9 inclusive.
Refitting
29Commence refitting by lubricating the
camshaft, bearings and thrustplate with
hypoid oil, then carefully insert the camshaft
from the front of the cylinder head, taking care
not to damage the bearings.
30Locate the thrustplate in position in the
cylinder head, then refit the bolts and tighten
them. Note that the oil groove in thethrustplate must face the front of the engine.
31Using a dial test indicator (if available) or
feeler blades, check that the camshaft
endfloat is within the limits given in the
Specifications. If not, renew the thrustplate
and re-check. If this does not bring the
endfloat within limits, the camshaft must be
renewed.
32Smear the lip of the new camshaft oil seal
with clean engine oil, then refit the seal using
the camshaft sprocket bolt and a suitable
tool. The tool can be improvised using a metal
tube of suitable diameter and a large washer
or metal disc. Draw the seal into position so
that it rests on the shoulder.
33Lubricate the cam followers with hypoid
oil, then refit them to their original locations in
the cylinder head.
34Before each rocker arm is fitted and its
(new) nut tightened, it is essential to ensure
that the relevant cam follower is positioned at
its lowest point (in contact with the cam base
circle, not the tip of the cam lobe). Turn the
camshaft (by means of the camshaft sprocket
bolt if necessary) as necessary to achieve this.
35Lubricate the tops of the cam followers,
then refit the spacer plates, rocker arms and
rocker arm guides to their original locations.
36Secure the rocker arms using new nuts
tightened to the specified torque, bearing in
mind the point made in paragraph 34.
37Refit the cylinder head.

1Refer to Section 26, Chapter 2, PartA but
also note the following points.
2The flywheel/driveplate securing bolts must
be renewed when refitting, and the new bolts
are supplied ready-coated with threadlocking
compound (see illustration).
3The ring gear cannot be renewed
independently of the flywheel/driveplate. If the
ring gear is badly worn or has missing teeth, a
new flywheel/driveplate must be fitted.

Chapter 6 when removing the clutch.
6The flywheel securing bolts must be
renewed when refitting, and the new bolts are
supplied ready-coated with thread-locking
compound.
7The ring gear cannot be renewed
independently of the flywheel. If the ring gear
is badly worn or has missing teeth, a new
flywheel must be fitted. Similarly, the flywheel
must be renewed if the crankshaft
speed/position sensor toothed disc is
damaged.

1Remove the timing belt and the crankshaft
sprocket and thrustwasher.
2Withdraw the oil seal using an oil seal
removal tool or by drilling the oil seal outer
face and using self-tapping screws and a pair
of grips.
3Clean the oil seal housing, then smear the
lip of a new oil seal with clean engine oil.
4Fit the oil seal using the crankshaft pulley
bolt and a suitable tool similar to that shown
(see illustration).5As the seal is drawn into position, the inner
edge of the seal may be damaged as it passes
over the end of the shaft. To prevent this, as
soon as the seal begins to locate in the
housing remove the tools being used to fit the
seal, and carefully work the inner edge of the
seal over the end of the crankshaft, using a
small screwdriver or similar blunt tool. The
seal can then be pushed home using the tools
described previously (see illustration).
6Refit the thrustwasher, crankshaft sprocket
and timing belt.

8Proceed as described in paragraphs 2 to 4
inclusive.
9Refit the thrustwasher, crankshaft sprocket
and timing belt.
1Remove the flywheel/driveplate.
2Prise out the oil seal. If necessary, drill the
outer face of the oil seal and use self-tappingscrews and a pair of grips to withdraw the
seal (see illustration).
3Clean the oil seal housing, then fit the new
oil seal using two flywheel/driveplate securing
bolts and a tool similar to that shown (see
illustration). A suitable tool can be
improvised using a narrow strip of metal sheet
bent to form a circle of the correct diameter,
and a large metal disc with appropriate holes
drilled to allow the flywheel/driveplate
securing bolts to pass through. Make sure
that the seal lip faces into the engine and
lightly smear the lip with clean engine oil.
4Refit the flywheel/driveplate.
Note: A new gasket and new sump bolts must
be used when refitting, and suitable sealant will
be required (available from a Ford dealer). Note
that it is preferable to keep the engine upright
until the sump has been removed to prevent
sludge from entering the engine internals.
