Q
1.
Make certain that all parts are marked or identified
so
they are installed in their original positions. Using
a clean dry cloth, thoroughly clean all oil from
crankshaft journal and connecting rod. If connecting
rod bearing inserts are being replaced
(P224
only),
install them in rod and cap.
2.
Place a piece of correct size Plastigauge in the
bearing cap the full width
of
the journal surfaceand
about
1 /4
inch
(6.35
mm)
off
center (Figure
24).
3.
Rotate the crankshaft about
30
degreesfrom bottom
dead center and reinstall the bearing cap; tighten
rod bolts to the torque specified in
ASSEMBLY
TORQUES
AND
SP€C/AL
TOOLS.
Do not turn the
crankshaft.
4.
Remove bearing cap. The flattened Plastigauge will
be found adhering to either the bearing cap or

crankshaft.
OIL SEALS
The bearing plate must be removed to replace the oil
Seal (Figure
25).
Drive the
Oil
Seal Out from the inside.
Before installing seals, fill the space between
lips
with a
multi-purpose grease. This will improve sealing.
5.
Compare flattened Plastigauge with the graduations
on Plastigauge envelope to determine clearance.
The number within the matching graduation on the
envelope indicates total clearance in millimeters or
thousandths of an inch.
When installing the gear cover oil seal, tap the seal
inward until
it
is
,645
inch
(16.4
mm)from thefront of the
gear cover.
When installing the bearing plate oil seal, tap the seal
into the bearing plate bore to bottom against the
shoulder in the plate bore. Use aseal expander or place
a piece
of
heavy paper around the end of the crankshaft,
when replacing the bearing plate to avoid damaging the
seal. Remove the paper as soon as the plate
is
in place.
