2The big-end bearing shells can be renewed
without having to remove the cylinder head if
the caps are unbolted and the
piston/connecting rod pushed gently about
one inch up the bore (the crankpin being at its
lowest point). If these shells are worn,
however, the main bearing shells will almost
certainly be worn as well. In this case, the
engine should be removed for complete
overhaul including crankshaft removal.
3To remove the piston/connecting rods,
remove the cylinder head as described in
Section 29.
4Grip the oil pick-up pipe and twist or rock it
from its hole in the crankcase. It is an
interference fit in the hole.
5Unscrew the nuts from the big-end caps,
then remove the caps with their bearing
shells. The caps and their connecting rods are
numbered 1, 2, 3 and 4 from the timing cover
end of the engine. The numbers are adjacent
at the big-end cap joint and on the side of the
crankcase furthest from the auxiliary shaft.
6If the bearing shells are to be used again,
tape them to their respective big-end caps.
7Push each connecting rod/piston assembly
up the bore and out of the cylinder block.
There is one reservation; if a wear ridge has
developed at the top of the bores, remove this
by careful scraping before trying to remove
the piston/rod assemblies. The ridge will
otherwise prevent removal or break the piston
rings during the attempt.
8If the connecting rod bearing shells are to
be used again, tape the shells to their
respective rods.
9Dismantling the piston/connecting rod is
described in Section 18.
Refitting
10Fit the new shells into the connecting rod
and caps, ensuring the surfaces on which the
shells seat, are clean and dry.
11Check that the piston ring gaps are evenly
spaced at 120º intervals. Liberally oil the rings
and the cylinder bores.
12Fit a piston ring clamp to compress the
rings.
13Insert the piston/connecting rod into the
cylinder bore, checking that the rod assembly
is correct for that particular bore. The cap and
rod matching numbers must be furthest away
from the auxiliary shaft (Fig. 1.31).14Push the piston into the bore until the
piston ring clamp is against the cylinder block
and then tap the crown of the piston lightly to
push it out of the ring clamp and into the bore
(photo).
15Oil the crankshaft journal and fit the
big-end of the connecting rod to the journal.
Fit the big-end cap and nuts, checking that
the cap is the right way round (photo).
16Tighten the big-end nuts to the specified
torque. The correct torque is important as the
nuts have no locking arrangement. After
tightening each big-end, check the crankshaft
rotates smoothly (photo).
17Refit the oil pick-up pipe, the cylinder
head, oil pump and sump pan, all as
described earlier.
18Refill the engine with oil and coolant.
33 Engine mountings-
renewal
1
1Three engine/transmission flexible
mountings are used.
2To renew a mounting, support the weight of
the engine/transmission on a hoist or jack and
unbolt and remove the mounting.
3In the unlikely event of all three mountings
requiring renewal at the same time, only
disconnect them and renew them one at a
time.
34 Engine- method of removal
1The engine complete with transmission
should be removed by lowering it to the floor
and withdrawing it from under the front of the
car which will have been raised to provide
adequate clearance.
35 Engine/transmission-

front roadwheels.
17Unscrew and remove the driveshaft to
hub nuts. These are very tight and a long
knuckle bar will be required when unscrewing
them. Have an assistant apply the brake pedal
hard to prevent the hub from turning.
18Working under the car, remove the inner
wing protective shields and then disconnect
the exhaust downpipe from the manifold.
19Disconnect the exhaust pipe sections by
removing the socket clamp just forward of the
rear axle beam. Remove the front section.
20Disconnect the forward ends of the
gearchange rods by prising their sockets from

45 Engine- initial start-up after
major overhaul
4
1If new bearings and rings have been fitted,
it is likely that the engine will be stiff to turn so
make sure the battery is well charged.
2Switch on the ignition and check that
appropriate warning lights come on.
3Start up the engine. If it refuses to start,
refer to the “Fault Finding” Section in the
Reference section of this Manual.
4Watch the oil pressure warning light and
alternator charging indicator light. If there is
no charge or if the oil pressure warning light
does not go out after a second or two, havinghad time to fill the new oil filter, switch off and
recheck.
5If the warning lights go out, set the engine
to run on fast idle and check the engine for
leaks.
6Check the coolant level; it will probably go
down as air locks are filled.
7Keep the engine running at a fast idle and
bring it up to normal working temperature. As
the engine warms up, there will be some odd
smells and smoke from parts getting hot and
burning off oil deposits.
8When the engine running temperature has
been reached, adjust the idling speed, as
described in Chapter 3. Check and, if
necessary, adjust the ignition timing using a
stroboscope (see Chapter 4).
9Stop the engine and wait a few minutes;
check to see if there are any coolant or oil
leaks.
10Road test the car to check that the engine
is running with the correct smoothness and
power. If it does not, refer to “Fault finding” in
the Reference section of this Manual. Do not
race the engine. If new bearings and/or
pistons and rings have been fitted, it should
be treated as a new engine and run it at
reduced speed for at east 800 km (500 miles).
11After 800 km (500 miles) change the
engine oil and filter.

17 Handbrake cable-
renewal
1
1There are two cables, either of which may
be renewed independently
2Disconnect the cable, which is to be renewed,
from the shoe lever at the brake backplate.
3Disconnect the longer cable from the
primary link or rod and release the cable from
its retainers. On later models with a plastic
fuel tank, a cable bracket is moulded into the
side of the tank (photo).4Disconnect the shorter cable from the pivot
lever at the pulley on the rear axle (photo).
5Refit the new cables by reversing the
removal operations and then adjust as
described in the preceding Section.

ease the holder out of the alternator. Inspect
the brushes and if worn below the specified
minimum length, they must be renewed.
7Disconnect the brush leads by unsoldering
or carefully cutting them.
8When soldering the new brush leads, do
not allow solder to run down them or their
flexibility will be ruined.
9When inspecting or renewing brushes,
check the surface of the slip rings. Clean them
with solvent or if they are very discoloured,
use very fine glasspaper.
6 Voltage regulator
1This is of integral type and is part of the
brushholder assembly.
2No provision is made for adjustment or
overhaul.
7 Starter motor-
description and testing
2
1The starter motor may be one of two
different makes. Both are of pre-engaged
type.
2This type of starter motor incorporates a
solenoid mounted on top of the starter motor
body. When the ignition switch is operated,
the solenoid moves the starter drive pinion,
through the medium of the shift lever, into
engagement with the flywheel starter ring
gear. As the solenoid reaches the end of its
stroke, and with the pinion by now partially
engaged with the flywheel ring gear, the main
fixed and moving contacts close and engage
the starter motor to rotate the engine.
3This pre-engagement of the starter drive
does much to reduce the wear on the flywheel
ring gear associated with inertia type starter
motors.
4If the starter fails, some fault-finding can be
done with it still on the car. Check the ignition
warning light comes on, and does not go out
when the starter is switched on. If it goes out,
the fault is probably in the battery. If it stays
bright, get an assistant to work the switch,whilst listening to the starter. Listen to find out
if the solenoid clicks into position. If it does
not, pull off the solenoid wire, and check it
with a test bulb. If the wire is live when the key
is turned, but the solenoid does not move,
take off the starter and remove it to the bench
for overhaul.
8 Starter motor-
removal and refitting
1
1Disconnect the battery negative lead.
2Disconnect the lead from the starter motor
(photo).
3Unscrew the fixing bolts and withdraw the
starter motor, downwards on 1116 cc and
1301 cc models (photo).
4Refitting is a reversal of the removal
procedure.
9 Starter motor- overhaul
3
1As with the alternator, the operations
should normally be limited to renewal of the
brushes. If the unit has covered a high
mileage it will usually be more economical to
purchase a new or factory-reconditioned one
rather than renew several components of the
original unit.
2Owing to the possibility that a fault can
develop in the starter motor solenoid or drive
assembly, full dismantling procedures are
given later in this Section.
Brush - renewal
3Slide off the cover band.
4Using a hooked piece of wire, pull up the
springs so that the brushes can be withdrawn
and their lengths checked for wear. If they
have worn below the specified minimum
length, renew them by extracting the brush
lead connecting screws (photo).
Solenoid
5Disconnect the field connecting wire from
the solenoid.
6Unscrew the bolts which hold the solenoid
to the end-frame.
7Unscrew the yoke tie-rod nuts.

3 Routine maintenance- all models from June 1991
The maintenance intervals in this manual are provided with the
assumption that you, not the dealer, will be carrying out the work.
These are the minimum maintenance intervals recommended by us, for
vehicles driven daily. If you wish to keep your vehicle in peak condition
at all times, you may wish to perform some of these procedures more
often. We encourage frequent maintenance, since it enhances the
efficiency, performance and resale value of your vehicle.
If the vehicle is driven in dusty areas, used to tow a trailer, or driven
frequently at slow speeds (idling in traffic) or on short journeys, more
frequent maintenance intervals are recommended.
When the vehicle is new, it should be serviced by an authorised
dealer to preserve the factory warranty.
