Main bearing cap removed showing the location of the rear seal and sealant grooves.
until the sealant appears at the inner, lower edge of the
bearing cap to cylinder block joint. Install the bearing
cap bolts and tighten to the specified torque.

(5) Tighten the remaining main bearing cap
bolts and the connecting rod cap bolts to their
respective tensions and rotate the crankshaft to check
for binding. (6) Install the crankshaft oil seal to the end of the
crankshaft after applying lithium grease to the lip of
the oil seal. Ensure that the l i p of the seal is facing
towards the engine.
(7) Install the remainder of the engine compo-
nents by referring to the relevant headings in this
section.
TO RENEW MAIN BEARINGS -
CRANKSHAFT INSTALLED

(1) Remove the automatic transaxle or manual
transaxle as described in the appropriate section.

(2) Remove the flywheel/drive plate as outlined
under the Flywheel/Drive Plate heading. (3) Remove the engine sump and oil pump
pickup pipe as previously described. (4) Ensure that the main bearing caps are num-
bered to ensure correct assembly. (5) Remove the main bearing cap bolts and
remove the bearing cap and half shell of the bearing to
be renewed. Thoroughly clean the bearing cap in
solvent. (6) Where necessary, use the Plastigage method
to measure the bearing clearance.
(7) Position a piece of Plastigage the approxi-
mate length of the bearing width, across the bearing
shell in the cap and tigh ten the cap bolts to the
specified torque. Do not rotate the crankshaft. (8) Remove the bearing cap and measure the
spread width of the Plastigage with the scale on the
packet to determine the main bearing clearance.
Compare the measurement to the Specifications and if
the bearing clearance exceeds the limit, install a new
set of bearing shells.
NOTE: Renew one bearing at a time, leav-
ing the others securely attached.

(9) Install a brass rivet in the crankshaft journal
oil drilling and rotate the crankshaft in a clockwise
direction until the head of the rivet contacts the plain
edge of the upper bearing shell. (10) Continue to rotate the crankshaft to carry
the upper half of the bearing shell out of the crank-
case.
(11) Select a half shell of the required thickness
(standard or undersize), coat it liberally with clean
engine oil and start it, plai n edge first, into position on
the crankshaft. Rotate the crankshaft anti-clockwise so
that the rivet contacts the locating lug edge of the
bearing shell, carrying it into position in the crankcase
above the main bearing journal. Slightly reverse the
rotation of the crankshaft and remove the rivet from
the oil drilling in the crankshaft. (12) Place the other half shell of the selected
bearing shells in the bear ing cap. checking the clear-
ance as detailed in operations (7) and (8).
NOTE: By checking the taper on the plas-
tigage any taper of the bearing journal can
be calculated.

(13) When the bearing has been correctly selected
to give the specified clearance, tighten the cap bolts to
the specified torque. (14) Use the same method to renew the other
main bearings. (15) When renewing the rear main bearings, re-
move and discard the rear crankshaft oil seal. (16) Install the rear main bearing cap into position
and inject KP510-00150 sealant or equivalent into the
grooves in the sides of the rear bearing cap. Fill the
grooves until the sealant a ppears at the inner lower
View showing the numbering and correct location of
the main bearing caps.

To Adjust Temperature Control Rod and Cable
If the temperature control rod requires adjust-
ment it will be necessary to remove the heater unit

under the heading To Remove and Install Heater Unit.

(1) Working in the passenger footwell disconnect
the temperature control cable from the clip on the side
of the heater unit. (2) Set the heater controls to the maximum heat
position. (3) Hold the air mix door lever clockwise while
lightly pulling on the outer control cable to remove
slack, then install the control cable into the retaining
clip.
(4) With the engine at operating temperature
check the operation of the temperature control lever.

TO ADJUST HEATER CONTROLS
To Adjust Air Control Door Rods and Cable
(1) Disconnect the air control cable from the
side link. (2) Working on the right hand side of the heater
unit disconnect the upper and lower door lever and
demist door lever rods from the retaining clips.
(3) Hold the side link fully anti-clockwise.
(4) Hold the upper and lower door levers fully To Adjust Air Control Cable

(1)
Working in the passeng er footwell, discon-
nect the intake air control cable from the clip on the
intake unit. (2) Set the air intake lever to the recirculate
position. (3) Hold the intake lever to wards the front of the
vehicle and install the control cable into the
retaining
clip.
(4) Check the operation of the air intake control.

working on or near the electronic ignition system as dangerous high tension voltages
are produced in both the primary and secondary circuits. See the text fo\

TROUBLE SHOOTING

NOTE: The following Trouble Shooting pro-
cedures are basic checks only. If these pro-
cedures fail to locate the fault, refer to the
System Diagnosis and Adjustments heading
for more thorough testing.

Prior to performing any of the following
operations, refer to the Service Precautions
and Procedures heading.

ENGINE WILL NOT START OR HARD TO
START
(1) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(2) Fault in the power supply: Check the battery,
fusible links and fuses. Check for clean, secure con-
nections, particularly the earth connections. Check the
EG1 and fuel pump relays.
NOTE: If the fuel pump relay fails, power
will be supplied to the fuel pump via the oil
pressure switch. When starting the engine,


Check that the MAP sensor hose is not blocked or split
and ensure that all electrical connections are clean and
secure.

Brakes 181

chor plate to the steering knuckle and slide the caliper
off the brake disc. Suspend the caliper clear of the
work area using wire or cord.

(3) Suitably mark the location of the disc in
relation to the hub.

(4) Slide the disc off the hub. If the disc is
difficult to remove, install two M8 x 1.25 mm bolts in
the disc and by alternatively tightening the bolts,
remove the disc.

Do not use a hammer to remove the disc.
Installation is a reversal of the removal procedure
ensuring that the mating face s of the disc and hub are
clean and free from burrs and that the marks made on
removal are aligned.

To Inspect
(1) Inspect the machined faces of the disc for
scores, cracks, wear and signs of overheating. (2) Using a micrometer, measure the thickness
of the disc at several positi ons around the face of the
disc. Renew the disc if the minimum thickness is
below Specifications.

Inspect the brake discs for scoring and wear.
(3) If the disc thickness is satisfactory but the
disc is scored, machine equal amounts from the
machined face on each side of the disc, to restore the
serviceability of the disc.

NOTE: Disc machining is best entrusted to
a reliable brake specialist who can advise on
disc serviceability.

6. REAR DISC BRAKES
Special Equipment Required:
To Check Disc Runout — Dial gauge
To Check Disc Thickness — Micrometer
TO CHECK AND RENEW BRAKE PADS
( 1 ) Raise the rear of the vehicle and place it on
chassis stands. Remove the rear wheels.


Renew the rear brake pads if the friction material is less
than 2 mm thick.
(2) Inspect the brake pads on both sides of the
vehicle. If the friction material on one or more of the
pads is less than 2 mm thick or contaminated with
fluid or grease, renew the brake pad as a set as follows.

NOTE: If the brake pads are contaminated
trace and rectify the cause prior to installing
the new set of pads.

(3) Drain approximately two thirds of the brake
fluid from the master cylinder reservoir. This can be
done by loosening the bleeder valve on the caliper and
allowing the fluid to drai n into a container. Discard
this fluid.

NOTE: Do not drain all the fluid from the
reservoir otherwise it will be necessary to
bleed the hydraulic system. The fluid is
drained from the reservoir to prevent over-
flow when the caliper piston is pushed back
into the caliper bore to facilitate pad re-
newal.

(4) Remove the guide bolts and lift the caliper
body clear of the disc.

NOTE: Do not allow the caliper to hang on
the brake hose.

(5) Noting the installed positions, remove the
brake pads, shims and spring clips from the anchor
plate.
(6) Using a pair of long nosed pliers with the
nose located in the recesses of the piston, rotate the
piston clockwise to retract it into the cylinder body.
Align the recesses between the brake pad retaining
lugs on the caliper body. Refer to the illustration. (7) If necessary, check the disc runout and
thickness as described under the Brake Disc heading.
(8) Ensure that the guide bolts move freely in the
caliper body and that the dust boots are in good
condition.
