End Play Inspection/Adjustment

Before reassembling the crankcase,the following steps should be performed to determine the amount of crank-

shaft, counter balancer shaft, and pump 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.

1. Make sure all bearings are firmly seated in the

both Mag and PTO crankcase.

2. Measure the distance from the PTO crankcase

mating surface to the main bearing using a dial

caliper and a straight edge.

3. Subtract the thickness of the straightedge from

the measurement obtained in Step 2 and record.
