Inspect the rear face of the gear housing and flywheel
housing mounting surface for cleanliness and raised nicks
or burrs.
Use fine crocus cloth to remove small nicks and burrs.
Thoroughly clean the flywheel housing and gear housing
mating surfaces. These surfaces must be clean of oil and
debris.
Measure
NOTE: Follow this step only if the flywheel housing (or
rear gear housing for rear gear train engines) is being
replaced or if troubleshooting a vibration/alignment issue.
It is not necessary to measure bore alignment or face
alignment when installing the original flywheel housing
unless the dowel rings were removed during a previous
repair.
Install the flywheel housing following the Install Step of
this procedure, but do not torque the capscrews. Only
tighten the capscrews enough to hold the flywheel wheel
in place.
Service Tip: For rear gear train engines, when installing a
new flywheel housing to check flywheel housing bore
alignment and face alignment, do not apply sealant to the
flywheel housing prior to installing for measurement.
CAUTION
When barring the engine using service tool, Part
Number 3824591, be careful to not apply excessive
side loading to the flywheel housing. This may cause
the flywheel housing to move and cause inaccurate
measurement readings.
CAUTION
The dial indicator tip must not enter the capscrew
holes, or the gauge will be damaged.
Face alignment is determined by calculating the total
indicator reading (TIR).
Attach the dial indicator gauge, Part Number 3376050, to
the crankshaft. Use mounting tool, Part Number ST1325,
to attach the dial indicator to the crankshaft as illustrated.
NOTE: The dial indicator can be mounted by any method
that holds the extension bar of the indicator rigid, so it
does not sag. If the bar sags or the indicator slips, the
readings obtained will not be accurate.
Position the indicator at the 12-o'clock position, and zero
the gauge.
NOTE: The crankshaft must be pushed toward the front
of the engine to remove the crankshaft end clearance
each time a position is measured.
