Inspection
1. Mount the crankshaft center main
bearings in a set of V—blocks, and mea—
sure the run—out of the crankshaft with a
dial gauge. Measurements should be
taken at either end of the crankshaft and
on each of the flywheels. If the run—out
exceeds the service limit, the crankshaft
should be replaced.
2. With the crankshaft supported at
both ends, mount a dial gauge to the top
of each main bearing in turn. Attempt to
move the outer race up and down. The
measurement on the dial gauge is the
total radial clearance. Ifthe clearance ex—
ceeds the service limit, the crankshaft
should be replaced.
