CONNECTING ROD AND MAIN BEARINGS
Bearings are available with a smaller inside
diameter than the original size bearings. These
bearings are for crankshafts that have been "ground"
(made smaller than the original size). Main bearings are
available with a larger outside diameter than the original
size bearings. These bearings are for cylinder blocks
that have had the bore for the main bearings "bored"
(made larger than the original size).
FLYWHEEL AND FLYWHEEL HOUSING
Tools Needed:
8S2328 Dial Indicator Group.
Heat the ring gear to install it. Do not heat to
more than 4000 F (204° C). Install the ring gear so the
chamfer on the gear teeth is next to the starter pinion
when the flywheel is installed.
Face Runout (axial eccentricity) of the Flywheel
Housing
If any method other than given here is used,
always remember bearing clearances must be removed
to get correct measurements.
1.
Fasten a dial indicator to the crankshaft flange
so the anvil of the indicator will touch the face of
the flywheel housing.
2.
Force the crankshaft to the rear before reading
the indicator at each point.

3.
With the dial indicator set at .000 in. at location
(A), turn the crankshaft and read the indicator at
locations (B), (C) and (D).
4.
The difference between lower and higher
measurements taken at all four points must not
be more than .010 in. (0.25 mm), which is the
maximum
permissible
face
runout
(axial
eccentricity) of the flywheel housing.
