Method B (Using plastigage)
CAUTION:
lDo not turn crankshaft or connecting rod while plasti-
gage is being inserted.
lWhen bearing clearance exceeds the specified limit,
ensure that the proper bearing has been installed. Then
if excessive bearing clearance exists, use a thicker main
bearing or undersized bearing so that the specified bear-
ing clearance is obtained.
CONNECTING ROD BUSHING CLEARANCE (Small
end)
1. Measure inner diameter ``C'' of bushing.
2. Measure outer diameter ``Dp'' of piston pin.
3. Calculate connecting rod bushing clearance.
CþDp=
þ0.015 to þ0.033 mm (þ0.0006 to þ0.0013 in) (Stan-

If out of specification, replace connecting rod assembly
and/or piston set with pin.

1. Heat piston to 60 to 70ÉC (140 to 158ÉF) and assemble
piston, piston pin and connecting rod.
lAlign the direction of piston and connecting rod.
lNumbers stamped on connecting rod and cap corre-
spond to each cylinder.

Precautions for SRS ``AIR BAG'' Service
lDo not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait for at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag to deploy.
Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
lFor 2WD models, do not separate diagnosis sensor unit from steering wheel.
lFor 4WD models, diagnosis sensor unit must always be installed with their arrow marks ``S'' pointing
towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks,
deformities or rust before installation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt
to turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place it with the pad side facing upward.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.

Removal Ð Air Bag Module and Spiral Cable
CAUTION:
lBefore servicing SRS, turn the ignition switch off, dis-
connect both battery cables and wait for at least 3 min-
utes.
lAlways work from the side of air bag module.
1. Remove lower lid from steering wheel, and disconnect air
bag module connector.
2. Remove side lids. Using the TAMPER RESISTANT TORX
(Size T50), remove left and right special bolts. Air bag mod-
ule can then be removed.
CAUTION:
lAlways place air bag module with pad side facing
upward.
lDo not attempt to disassemble air bag module.
lThe special bolts are coated with bonding agent. Do not
use old bolts after removal; replace with new ones.
lReplace air bag module if it has been dropped or sus-
tained an impact.
lDo not expose the air bag module to temperatures
exceeding 90ÉC (194ÉF).
lDo not allow oil, grease or water to come in contact with
the air bag module.
3. Set steering wheel in the neutral position.
4. Disconnect horn connector (Dual Air Bag System)/spiral
cable steering connector (Single Air Bag System) and
remove nuts.
5. Using steering wheel puller, remove steering wheel. Be care-
ful not to over-tighten puller bolt on steering wheel.
CAUTION:
lDo not tap or bump the steering wheel.
6. Remove steering column cover.
7. Disconnect connectors and remove the four screws. The spi-
ral cable can then be removed.
