14Take the weight of the engine and remove
the two engine bearer-to-mounting nuts.
15Lift the engine/transmission, at the same
time lowering the trolley jack. Draw the unit
forwards and lift it out of the engine bay.
16Temporarily refit the anti-roll bar if the
vehicle is to be moved.
1With the engine and gearbox on the bench,
remove the starter motor.
2Remove the bolt from the engine adapter plate.
3Remove the bracing strap and the
remaining engine-to-bellhousing bolts.
4With the aid of an assistant draw the
gearbox off the engine. Do not allow the weight
of the gearbox to hang on the input shaft.
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 be 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 on a concrete
floor, as grit can be a real source of trouble.
4As parts are removed, clean them in paraffin.
However, do not immerse parts with internal
oilways in paraffin as it is difficult to remove,
usually requiring a high pressure hose.
5It is advisable to have suitable containers to
hold small items according to their use, as this
will help when reassembling the engine and
also prevent possible losses.
6Always obtain complete sets of gaskets
when the engine is being dismantled, but
retain the old gaskets with a view of using
them as a pattern to make a replacement if a
new one is not available.7When possible, refit nuts, bolts and washers
in their location after being removed, as this
helps protect the threads and will also be
helpful when reassembling the engine.
8Retain unserviceable components in order
to compare them with the new parts supplied.
9A Torx key, size T55, will be needed for
dealing with the cylinder head bolts. A 12-
spline key (to fit bolt size M8) will be needed
for the oil pump bolts. Other Torx and 12-
spline bolts may be encountered; sets of the
keys required to deal with them are available
from most motor accessory shops and tool
factors.
10Another tool which is useful, though by no
means essential, is a valve spring compressor
of the type which hooks under the camshaft
(see illustration). As a Ford tool this bears the
number 21-005-A; proprietary versions may
also be available.
Before dismantling the engine into its main
components, the following ancillary
components can be removed. The actual
items removed, and the sequence of removal,
will depend on the work to be done:
Inlet manifold and associated items
Exhaust manifold
Fuel pump (mechanical type) and pushrod
Alternator
Distributor, HT leads and spark plugs
Fan, water pump and thermostat
Oil pressure switch
(see illustration)
Temperature gauge senderOil filter and dipstick
Engine bearer arms (see illustration)
Crankcase ventilation components
Clutch
Alternator mounting bracket (see
illustration)
1If the engine is still in the vehicle, carry out
the following preliminary operations:
a)Disconnect the battery negative lead
b)Drain the cooling system
c)Remove the inlet and exhaust manifolds
d)Disconnect the radiator top hose from the
thermostat housing, and the spur from the
expansion tank
e)Disconnect the wiring from the
temperature gauge sender
f)Remove the distributor cap, HT leads and
spark plugs
2Unscrew the bolts and withdraw the timing
cover (see illustration). Note the location of
the cover in the special bolt.

6Using a Torx key, slacken the cylinder head
bolts half a turn at a time in the reverse of the
tightening sequence.7With the bolts removed, lift the cylinder
head from the block. If it is stuck, tap it with a
wooden or plastic mallet to free it. Do not
lever between the head and block, or the
mating surfaces may be damaged. Do not
crank the engine to free the head, as the
pistons may contact the valves.
8Place the cylinder head on a couple of
wooden blocks so that the protruding valves
are not damaged.
1Remove the cylinder head as described in
the previous Section.
2Hold the camshaft with a spanner on the lug
behind the sixth cam. Unscrew and remove
the camshaft sprocket bolt (see illustration).3Remove the camshaft sprocket using a
puller if necessary. Remove the backplate
(see illustration).
4Unscrew the bolts and remove the camshaft
oil supply tube (see illustration).
5Note how the cam follower retaining spring
clips are fitted, then unhook them from the
cam followers.
6If the special tool 21-005-A is available,
compress the valve springs in turn and remove
the cam followers, keeping them identified for
location. Alternatively loosen the locknuts and
back off the ball-pins until the cam followers
can be removed (see illustration).
7Unscrew the bolts and remove the camshaft
thrust plate (see illustration).
8Carefully withdraw the camshaft from the
rear of the cylinder head, taking care not to
damage the bearings (see illustration).

the following preliminary operations:
a)Disconnect the battery negative lead
b)Remove the radiator and disconnect the
hose from the thermostat housing
c)Remove the accessory drivebelt(s)
2Unscrew the bolts and withdraw the timing
cover. Note the location of the cover in the
special bolt.
3Using a socket on the crankshaft pulley bolt,
turn the engine clockwise until the TDC (top
dead centre) notch on the pulley is alignedwith the pointer on the crankshaft front oil seal
housing, and the pointer on the camshaft
sprocket is aligned with the indentation on the
cylinder head. Note the position of the
distributor rotor arm. Mark the contact end of
the rotor in relation to the rim of the distributor
body.
4Slacken the timing belt tensioner retaining
bolts then pivot the tensioner pulley away from
the belt, to obtain maximum drivebelt free play
(see illustration). Hold the tensioner pulley in
this position and securely retighten the
retaining bolts.
5Mark the running direction of the belt if it is
to be re-used, then slip it off the camshaft
sprocket.
6Slacken the crankshaft pulley bolt. Prevent
the crankshaft from turning by engaging 5thgear (manual gearbox), or by removing the
starter motor and jamming the ring gear teeth.
Alternatively, if the pulley has peripheral bolt
holes, screw in a couple of bolts and use a
lever between them to jam it. Do not allow the
crankshaft to turn very far, or piston/valve
contact may occur.
7Remove the bolt and washer and withdraw
the pulley. If the pulley will not come off easily,
refit the bolt part way and use a puller (see
illustration). A puller will almost certainly be
required on fuel-injection models.
8Remove the guide washer from in front of
the crankshaft sprocket, then remove the
timing belt (see illustration). Do not kink it or
get oil on it if it is to be re-used.
9Remove the crankshaft sprocket using a
puller if necessary (see illustration).

See Chapter 1, Section 8.
1Remove the sump and cylinder head.
2Check the big-end caps for identification
marks and if necessary use a centre-punch to
identify the caps and connecting rods (see
illustration).
3Turn the crankshaft so that No 1 crankpin is
at its lowest point, then unscrew the nuts and
tap off the cap. Keep the bearing shells in the
cap and connecting rod.4Using the handle of a hammer, push the
piston and connecting rod up the bore and
withdraw from the top of the cylinder block.
Loosely refit the cap to the connecting rod
(see illustration).
5Repeat the procedure in paragraphs 3 and 4
on the No 4 piston and connecting rod, then
turn the crankshaft through half a turn and
repeat the procedure on Nos 2 and 3 pistons
and connecting rods.
1With the engine removed from the vehicle,
remove the pistons and connecting rods as
described in the previous Section. (In fact it is
not necessary to push the pistons out of the
bores if no work is to be done on them.)2Remove the timing belt and crankshaft
sprocket, and the flywheel or driveplate. Also
remove the auxiliary shaft sprocket.
3Unbolt the crankshaft front oil seal housing
and auxiliary shaft front cover and remove the
gasket.
4Remove the oil pump and strainer.
5Check the main bearing caps for
identification marks and if necessary use a
centre-punch to identify them (see
illustration).
6Before removing the crankshaft check that
the endfloat is within the specified limits by
inserting a feeler blade between the centre
crankshaft web and the thrustwashers (see
illustration). This will indicate whether new
thrustwashers are required or not.
7Unscrew the bolts and tap off the main
bearing caps complete with bearing shells
(see illustration). If the thrustwashers are to
be re-used identify them for location.
8Lift the crankshaft from the crankcase and
remove the rear oil seal. Remove the
remaining thrustwashers (see illustrations).
9Extract the bearing shells keeping them
identified for location (see illustration).
1Unscrew the two nuts which secure the
engine bearers to the tops of the mountings.

3Note that undersize bearings may already
have been fitted, either in production or by a
previous repairer. Check the markings on the
backs of the old bearing shells, and if in doubt
take them along when buying new ones(see
illustrations).Production undersizes are also
indicated by paint marks as follows:
White line on main bearing cap - parent bore
0.40 mm oversize
Green line on crankshaft front counterweight
- main bearing journals 0.25 mm undersize
Green spot on counterweight - big-end
bearing journals 0.25 mm undersize
4If the crankshaft endfloat is more than the
maximum specified amount, new
thrustwashers should be fitted to the centre
main bearings. These are usually supplied
together with the main and big-end bearings
on a reground crankshaft.
5An accurate method of determining bearing
wear is by the use of Plastigage. The
crankshaft is located in the main bearings (and
big-end bearings if necessary) and the
Plastigage filament located across the journal
which must be dry. The cap is then fitted and
the bolts/nuts tightened to the specified
torque. On removal of the cap the width of the
filaments is checked against a scale which
shows the bearing running clearance. This
clearance is then compared with that given in
the Specifications (see illustration).
6If the spigot bearing in the rear of the
crankshaft requires renewal extract it with a
suitable puller. Alternatively fill it with heavygrease and use a close fitting metal dowel
driven into the centre of the bearing. Drive the
new bearing into the crankshaft with a soft
metal drift.
1The cylinder bores must be examined for
taper, ovality, scoring and scratches. Start by
examining the top of the bores; if these are
worn, a slight ridge will be found which marks
the top of the piston ring travel. If the wear is
excessive, the engine will have had a high oil
consumption rate accompanied by blue
smoke from the exhaust.
2If available, use an inside dial gauge to
measure the bore diameter just below the
ridge and compare it with the diameter at the
bottom of the bore, which is not subject to
wear. If the difference is more than 0.152 mm
(0.006 in), the cylinders will normally require
reboring with new oversize pistons fitted.
3Proprietary oil control rings can be obtained
for fitting to the existing pistons if it is felt that
the degree of wear does not justify a rebore.
However, any improvement brought about by
such rings may be short-lived.
4If new pistons or piston rings are to be fitted
to old bores, deglaze the bores with abrasive
paper or a “glaze buster” tool. The object is to
produce a light cross-hatch pattern to assist
the new rings to bed in. 5If there is a ridge at the top of the bore and
new piston rings are being fitted, either the top
piston ring must be stepped (“ridge dodger”
pattern) or the ridge must be removed with a
ridge reamer. If the ridge is left, the piston ring
may hit it and break.
6Thoroughly examine the crankcase and
cylinder block for cracks and damage and use
a piece of wire to probe all oilways and
waterways to ensure that they are
unobstructed.
1Examine the pistons for ovality, scoring and
scratches. Check the connecting rods for wear
and damage. The connecting rods carry a
letter indicating their weight class; all the rods
fitted to one engine must be of the same class
(see illustration).
2The gudgeon pins are an interference fit in
the connecting rods, and if new pistons are to
be fitted to the existing connecting rods the
work should be carried out by a Ford garage
who will have the necessary tooling. Note that
the oil splash hole on the connecting rod must
be located on the right-hand side of the piston
(the arrow on the piston crown faces forwards)
(see illustration).
3If new rings are to be fitted to the existing
pistons, expand the old rings over the top of
the pistons. The use of two or three old feeler
blades will be helpful in preventing the rings
dropping into empty grooves. Note that the oil
control ring is in three sections.
4Before fitting the new rings to the pistons,
insert them into the cylinder bore and use a
feeler blade to check that the end gaps are
within the specified limits (see illustrations).
5Clean out the piston ring grooves using a
piece of old piston ring as a scraper. Be
careful not to scratch the aluminium surface of
the pistons. Protect your fingers - piston ring
edges are sharp. Also probe the groove oil
return holes.
6Fit the oil control ring sections with the
spreader ends abutted opposite the front of the
piston. The side ring gaps should be 25 mm

(1.0 in) either side of the spreader gap. Fit the
tapered lower compression ring with the TOP
mark towards the top of the piston and the gap
150°from the spreader gap, then fit the upper
compression ring with the gap 150°on the
other side of the spreader gap. Note that the
compression rings are coated with a
molybdenum skin which must not be damaged.
7Note that the compression rings are made
of cast iron, and will snap if expanded too far.
Examine the surface of the camshaft
journals and lobes and the cam followers for
wear. If excessive, considerable noise would
have been noticed from the top of the engine
and a new camshaft and followers must be
fitted.
Check the camshaft bearings for wear and if
necessary have them renewed by a Ford
garage.
Check the camshaft lubrication tube for
obstructions and make sure that the jet holes
are clear. Obstruction of the holes can be due
to sludge build-up which occurs when regular
oil changes have been neglected.
Examine the auxiliary shaft for wear and
damage and renew it if necessary.
If the auxiliary shaft endfloat is outside the
limits given in the Specifications fit a new
thrust plate. If this does not bring the endfloat
within limits, renew the shaft.
Whenever the timing belt is removed it is
worthwhile renewing it, especially if it has
covered a high mileage. This is more important
on the 2.0 litre engine where stripped teeth on
the timing belt can cause the pistons to foul
the valves.If the ring gear is badly worn or has missing
teeth, it should be renewed. The old ring can
be removed from the flywheel by cutting a
notch between two teeth with a hacksaw and
then splitting it with a cold chisel. Wear eye
protection when doing this.
To fit a new ring gear requires heating the
ring to 204°C (400°F). This can be done by
polishing four equal sections of the gear,
laying it on a suitable heat resistant surface
(such as fire bricks) and heating it evenly with
a blow lamp or torch until the polished areas
turn a light yellow tinge. Do not overheat or the
hard wearing properties will be lost. The gear
has a chamfered inner edge which should go
against the shoulder when put on the flywheel.
When hot enough place the gear in position
quickly, tapping it home if necessary and let it
cool naturally, without quenching.
1This operation will normally only be required
at comparatively high mileages. However, if
persistent pinking occurs and performance
has deteriorated even though the engine
adjustments are correct, decarbonising and
valve grinding may be required.
2With the cylinder head removed, use a
scraper to remove the carbon from the
combustion chambers and ports. Remove all
traces of gasket from the cylinder head
surface, then wash it thoroughly with paraffin.
3Use a straight-edge and feeler blade to
check that the cylinder head surface is not
distorted. If it is, it must be resurfaced by a
suitably equipped engineering works.
4If the engine is still in the car, clean the
piston crowns and cylinder bore upper edges,
but make sure that no carbon drops between
the pistons and bores. To do this, locate two
of the pistons at the top of their bores and seal
off the remaining bores with paper and
masking tape. Press a little grease between
the two pistons and their bores to collect any
carbon dust; this can be wiped away when the
piston is lowered.5Examine the heads of the valves for pitting
and burning, especially the exhaust valve
heads. Renew any valve which is badly burnt.
Examine the valve seats at the same time. If
the pitting is very slight, it can be removed by
grinding the valve heads and seats together
with coarse, then fine, grinding paste.
6Where excessive pitting has occurred, the
valve seats must be recut or renewed by a
suitably equipped engineering works.
7Valve grinding is carried out as follows.
Place the cylinder head upside down on a
bench on blocks of wood.
8Smear a trace of coarse carborundum paste
on the seat face and press a suction grinding
tool onto the valve head. With a semi-rotary
action, grind the valve head to its seat, lifting
the valve occasionally to redistribute the
grinding paste. When a dull matt even surface
is produced on both the valve seat and the
valve, wipe off the paste and repeat the
process with fine carborundum paste as
before. A light spring placed under the valve
head will greatly ease this operation. When a
smooth unbroken ring of light grey matt finish
is produced on both the valve and seat, the
grinding operation is complete.
9Scrape away all carbon from the valve head
and stem, and clean away all traces of
grinding compound. Clean the valves and
seats with a paraffin soaked rag, then wipe
with a clean rag.
10If the guides are worn they will need
reboring for oversize valves or for fitting guide
inserts. The valve seats will also need
recutting to ensure that they are concentric
with the stems. This work should be given to
your Ford dealer or local engineering works.
11If the valve springs have been in use
for 20 000 miles (32 000 km) or more, renew
them. Always renew the valve stem oil seals
when the valves are removed.
1To ensure maximum life with minimum
trouble from a rebuilt engine, not only must
everything be correctly assembled, but it must
also 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.
2Before assembly begins, renew any bolts or
studs with damaged threads.
3Gather together a torque wrench, oil can,
clean rag, and a set of engine gaskets and oil
seals, together with a new oil filter.
4If they have been removed, new cylinder
head bolts and flywheel bolts will also be
required.
