VEHICLE IDENTIFICATION AND GENERAL SPECIFICATIONS

1. VEHICLE IDENTIFICATION
When purchasing spare parts or when
registering
or insuring a vehicle, it may be necessary to quote
various vehicle identification codes. The location of
these codes are as follows: The Engine Number is stamped on the front
face
of the engine block below No. 4 spark plug. The Chassis Number is stamped on the bulkhead
above and to the right of the brake booster. The Vehicle Identification Plate is located on the
bulkhead to the left of the MAP sensor and contains
codings relating to body style, engine capacity,
model,
transaxle type, engine number, paint, trim and build
date. The Compliance Plate contains information on
the vehicle make, model, month and year of manu-
facture, chassis number, seating, capacity and the
Australian Design Rules (ADR) with which the vehi-
cle complies. This plate is affixed to the bulkhead
above and to the left of the brake booster. The Tire Placard, which is located on the inside
of the glove compartment, contains information
on
the tire size, rim size, tire pressure and load ratings.

10. PISTONS, CONNECTING RODS AND
CYLINDER BORES

Special Equipment Required:
To Inspect — Micrometer, cylinder measuring
gauge
To Remove Ridge from Bores — Ridge removal tool
To Deglaze Cylinder Bores — Cylinder surfacing
hone
To Install — Piston ring compressor
TO REMOVE
(1) Remove the engine sump and oil pump
pickup pipe as previously described. (2) Remove the cylinder head as previously
described. (3) Mark the relationship of the pistons to their
respective cylinders and the bearing caps to their
respective connecting rods by letter stamps or centre
punch marks. (4) Measure each connecting rod for side clear-
ance on the crankpin. Refer to the illustration. If the
clearance exceeds the Speci fications a new connecting
rod will have to be installed on assembly. (5) With number one cylinder on the bottom of
its stroke, remove the bear ing cap bolts and the
bearing cap. Wipe the bearing shell and the exposed part of the
journal with a piece of clean lint free cloth, insert a
piece of Plastigage across the journal, install the
bearing cap and tighten the bolts to the specified
torque.

Remove the bolts and cap and measure (with the
scale on the packet) the spread width of the Plastigage
to determine the bearing clearance.

Compare the measurement to the Specifications
and if the bearing clearance exceeds the limit, install a
new bearing on assembly.

Repeat the procedure on the remaining cylinders
and note each individual bearing clearance for assem-
bly purposes.

NOTE: Do not rotate the engine while the
Plastigage is in position or false readings
will result.

components.
(6) Remove each bearing cap in turn, keeping
them in order, and using a wooden hammer shaft,
push each piston assembly from the cylinder block
and install its respective bearing cap.

NOTE: Before removing the pistons, remove
the ridge from the top of the cylinder bore
using a ridge removal tool.

(7) Remove the piston rings over the top of the
piston and discard the piston rings.

rear main bearing cap and engine block. Discard the
oil seal.

(3) Ensure that all main bearing and connecting
rod bearing caps are numbered to ensure correct
assembly. (4) Remove the connecting rod bolts and caps,
keeping them in order. Push each piston and connect-
ing rod slightly up into the bore without pushing the
piston beyond its upper limit. (5) Check the crankshaft end float by inserting a
feeler gauge between the shaft and the centre main
bearing, or by mounting a dial gauge with its plunger
against one end of the shaft. (6) Push the crankshaft into contact with the
front edge of the centre main bearing, then lever the
shaft forward to determine the end float.
(7) If the end float exceeds the Specifications,
renew the centre main bearing on assembly. (8) Check the main bearing clearance by the
Plastigage method as follows:
(a) Remove one bearing cap and with a piece of
rag wipe the journal and bearing clean.
(b) Position a piece of Plastigage, the approxi-
mate length of the bearing width and slightly off
centre, on the bearing surface of the crankshaft
journal. (c) Install the bearing ca p and tighten the cap
bolts to the specified torque.
NOTE: Do not rotate the crankshaft while
the Plastigage is in position.

(d) Remove the cap bolts and carefully detach
the cap and lower half bearing. (e) With the Plastigage scal e, measure the com-
pressed Plastigage strip to determine the clearance. (f) The widest point of the strip will indicate the
minimum clearance and th e narrowest point the
maximum clearance. (g) The remaining bearings can be checked in
turn using the same procedure.
(9) Lift the crankshaft from the crankcase using
care not to dislodge or damage the upper halves of the
main bearing shells if they are to be used again. (10) If new bearing shells are to be installed,
remove the upper halves of the bearings from the
crankcase.
TO CHECK AND INSPECT

After thoroughly cleaning the crankshaft in sol-
vent and drying it with co mpressed air, blow out all
the oilways and make the following checks:

(1) Check and measure the main bearing jour-
nals and crankpins for wear, taper and scoring. If wear
is excessive, the journals and/or crankpins should be
ground to accommodate the nearest underside bearing
shells.

One worn or damaged journal or crankpin will
necessitate the grinding of all the journals or crank-

pins and the installation of new undersize bearing
shells.

If wear or damage is such that the journals or
crankpins cannot be reground to take any one range of
the available undersize bearings, the crankshaft will
have to be renewed.

(2) Support the crankshaft at each end in Vee
blocks and with a dial gauge, check the crankshaft for
bend at the centre main jour nal. Renew the crankshaft
if the bend is in excess of the allowable limit. Refer to
the Specifications.
(3) Check the centre main bearing side faces for
pitting or wear. If pitting or wear is evident, renew the
main bearing shells as a set which should restore the
crankshaft end float to the Specifications. (4) Even when the main bearing clearance has
been found to be satisfact ory, inspect the bearing
shells for scores, flaking and pitting. Renew the main
bearing shells as a set if necessary.
TO INSTAL

Installation is a reversal of the removal procedure
with attention to the following points:

(1) Ensure that all of the oilways are clear and
that all the journals and crankpins have been thor-
oughly cleaned. Ensure that the bearing shells have
been cleaned and smeared with new engine oil and that
they are correctly positioned in their respective web,
connecting rod or cap. (2) Carefully place the crankshaft in position in
the cylinder block and guide the connecting rods to
their respective crankpins.
(3) If new bearing shells were installed, check the
bearing clearance using the Plastigage method as
previously described. (4) Install the rear main bearing cap and inject
Permatex Ultra Grey or equivalent sealer into the grooves
in the side of the rear bearing cap. Fill the grooves.

Electrical System 217
When installing a trailer socket, it may be neces-
sary to replace the original vehicle flasher unit with a
heavy duty unit to maintain the flash rate in accor-
dance with local regulations. Local regulations may
also require the installation of a dashboard mounted
repeater lamp.

Should the trailer socket and plug not be matched,
adaptors can be made or obtained to facilitate con-
nection.

TO INSTAL TRAILER SOCKET.
The minimum materials required are a trailer
socket, mounting bracket, seven core flex, insulated
wiring connectors and a rubber grommet.

(1) Disconnect the negative battery terminal.
(2)Locate the wiring harness for the lamps at
the rear of the vehicle.

For five pin sockets and plugs, use the following
standard trailer wiring code:

(3) Identify the wires for the right turn signal
lamp, left turn signal lamp, tail lamp, stop lamp,
reverse lamp and earth. Use the vehicle wiring
diagram in this section to determine the wire color
for each lamp circuit.
(4)Connect the seven core flex to the various
lamp wires using insulated connectors.

(5) Drill a suitably si
zed hole through the vehicle
floor and install a rubber grommet to the hole.

NOTE: Before drilling the hole, check
whether there is an existing hole which may-
be used. Ensure that a rubber grommet is
installed to prevent chafing of the wires.

Pass the seven core flex through the rubber
grommet. Cut the seven core flex to the required length
and slide the dust cover onto the flex. Remove approximately 15 mm of insulation
from each wire in the flex.
Connect the wires of the seven core flex to
the terminals of the socket, using the standard wiring
code and following the socket manufacturers connec-
tion procedure. Assemble the socket and install the dust cover
to the rear of the socket. Install the mounting bracket as close as
possible to the tow bar ball and high enough to
maintain vehicle ground clearance. Install the socket to the mounting bracket.
Connect a trailer plug to the socket and test
for correct lamp operation.
TO INSTAL TRAILER PLUG

The minimum materials required are a trailer
plug, seven core flex and insulated wiring connectors.

The installation procedure for the trailer plug is
similar to that for the socket with attention to the
following points:

Connect the trailer wiring to the plug accord-
ing to the standard wiring color code and the plug
manufacturers instructions. Use a suitable length of
seven core flex and insulated connectors should the
trailer wiring not be long enough.
If the trailer wiring does not conform to the
standard color code, identify each circuit as follows: (a) Locate the trailer earth wire.
