– Dial Indicator Position for Crankshaft & Prop Flange Run Out
Remove one spark plug from each head.
Carefully sand off paint on crank diameter and prop flange where dial indicator will be located.
Position dial indicator onto crank as shown above and eliminate main bearing clearance by
bearing down on crank when rotating. Rotate crankshaft to measure crankshaft run out,
normally expect to see 0.01 - 0.03 mm, but if run out exceeds of 0.08 mm the crankshaft must
be replaced.
Position dial indicator onto prop flange as shown above, eliminate end float by either pulling or
pushing flange when rotating. Rotate prop flange to measure the face run out, normally expect
to see 0.02 - 0.06 mm, but if run out exceeds 0.08 mm then replace the prop flange.
