CRANKSHAFT SIDE CLEARANCE
• Using a dial gauge (A), measure the clearance between the thrust bearings and the crankshaft arm when the crankshaft is moved
fully forward or backward.
• If the measured value exceeds the limit, replace the thrust bear- ings, and measure again. If it still exceeds the limit, replace the
crankshaft.
