To check main bearing-to-iournal oil clearance,
remove the main caps and bearing halves.
Clean each main iournal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
na l-
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti'
gage further than just the torque on the cap bolt,
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (B18C1,
B18C5 engines only)then torque the bolts.

No. 2. 3, 4 cap bolts 64 N.m {6.5 kgf m. 49 lbf ftl
NOTE: Do not rotate the crankshaft during inspec-
tro n.
Remove the cap bridge (818C1, 818C5 engines
only), caps and bearings again, and measure the
widest part of the plastigage.
Main Bearing-to-Journal Oil Clearance:
Standard lNew):
No. 1, 2, 4, 5: 0.024 - 0.042 mm

No.3:0.030 - 0.048 mm
10.0012 - 0.0019 inl
Service Limit:0.060 mm {0.0024 inl
PLASTIGAGE STRIP
lf the plastigage measures too wide or too narrow,
{remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. lnstall a new, complete bearing with the same
color code (select the color as shown in the right
column), and recheck the clearance.
CAUTION: Do not file, shim. or scrape the bearings
or the caps to adiust clearance.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again.
NOTE: lf the oroDer clearance cannot be obtained
by using the appropriate larger or smaller bearings.
reolace the crankshaft and start over.
Selection
CAUTION: lf the codes ale indecipherable because of
an accumulation oI dirt and dust, do not scrub them
with a wire bru6h or scraper. Clean lhem only with sol-
vent or detergent.
Crankshaft Bore Code Location

Oil Seal
Installation
The seal surface on the block should be dry.
Apply a light coat of oil to the crankshaft and
the lip of the seal.
1. Drive in tlywheel end seal against right side cover.
NOTE: Drive the end seal in squarely.

The seal surface on the block should be dry.
Apply a light coat of grease to the crankshaft and
to the lip of seal.
1. Using the special tool, drive in the timing pulley-

pump.
When the seal is in place, clean any excess grease
off the crankshalt and check that the oil seal lip is
not distoned.

1.Inspect the ring gear teeth tor wear and damage.
Inspect the clutch disc mating surtace on the
flywheel for wear, cracks, and burning.
l\,reasure the flywheel runout using a dial indicator
through at least two full turns. Push agsinst the
Jlywheel each time you turn it to take up the crank-
shatt thrust washer clearance.
NOTE: The runout can ba measured with engine in-
stalled.

DIAL INOICATOR
lf the runout is more than the service limit, reolace
the flywheel.
Turn the inner race of the flywheel bearing with your
tinger. The bearing should turn smoothly and quiet-
ly. Check that the bearing outer race tits tightly in
the flvwheel.
FLYWHEELBEARING
lf the race does not turn smoothly, quietly, or tit
tight in the flywheel, replace the flywheel bearing.
