to check the top ring groove only.
PISTON RING GROOVE GAUGE
CONNECTING ROD AND MAIN BEAR
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 main bearings "bored" (made larger than the
original size).
FLYWHEEL AND FLYWHEEL HOUSIN(
Tools Needed:
8S2328 Dial Indicator Group.
Heat the ring gear to install it. Do not heat to more
than 400 F (204 C). Install the ring gear so the chamfer
on the gear teeth is next to the 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 moved to get correct
measurements.
1.
Fasten a dial indicator to the crankshaft flange
so the anvil of the indicator will touch face of the
flywheel housing.
2.
Force the crankshaft to the rear before reading
the indicator at each point.
8S2328 DIAL INDICATOR GROUP
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
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.
