Main Bearings
Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
nal.
NOTE: lf the engine is still in the car when you bolt
the main caD 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. Fot an accurate
reading, support the crank with a iack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (818C1
engine only) then torque the bolts.

PLASTIGAGE STNIP
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. Install 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 scrapo ihe bo.rings
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 Droper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
reolace the crankshaft and start over.

Reinstall the rod bearings and caps after removing
each piston/connecting rod assembly.
Mark each piston/connecting rod assembly with its
cylinder number to avoid mixup on reassembly.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.

EndPlay
NOTE; End play should be inspected before removing
crankshaft.
Push the crank firmly awav from the dial indicator, and
zero the dial against the end of the crank. Then pull the
crank firmly back toward the indicator; dial reading
should not exceed service limit.

. lf end play is excessive, inspect the thrust wash€rs
and thrust surface on the crankshaft. Replace pans as
necessary.
NOTE:
Thrust washer thickness is fixed and must not be
changed either by grinding or shimming.
Thrust washers are installed with grooved sides fac-
ing outward.
Crankshaft
lnspection
. Clean the crankshatt oil passages with pipe cleaners
or a suitable brush.
. Check the keyway and threads.
