CRANKCASE INSPECTION
1. Remove all traces of gasket sealer from the
crankcase mating surfaces. Inspect the surfaces
closely for nicks, burrs or damage.
BEARING INSTALLATION
NOTE: To ease crankshaft bearing installation, warm
the crankcase until hot to the touch. Place the bearing
in a freezer.
1. Install the crankshaft bearing so the numbers are
visible.
2. Drive or press the new bearing into the crankcase,
using the proper driver . CAUTION: Press only on
outer race of bearing to prevent bearing damage.
S70mm (2.755s) driver- For crankshaft main
bearings.
END PLAY INSPECTION/ADJUSTMENT
Before reassembling the crankcase,the following steps should be performed to determine the amount of crank-
shaft end play. Excessive end play may cause engine noise at idle and slow speeds. Too little play will side load
the bearings which may lead to premature bearing failure.
CRANKSHAFT END PLAY ADJUSTMENT
1. Make sure crankshaft bearing is firmly seated in
the MAG side crankcase.
2. Measure the distance from the MAG side
crankcase mating surface to the main bearing
using a dial caliper and a straight edge.
