Inspect crank pin for uneven wear or damage. Measure crank pin for out-of-round or taper with a micrometer. If crankpin is damaged, or
out-of-round or taper is out of limit, replace crankshaft or regrind crank pin to undersize and use undersize bearing.
Out-of-round: A - B
Taper limit: a - b
Out-of-round and taper limit: 0.01 mm (0.0004 inch)

Rod bearing:
Inspect bearing shells for signs of fusion, pitting, burn or flaking and observe contact pattern. Bearing shells found in defective condition must be
replaced.
Two kinds of rod bearing are available; standard size bearing and 0.25 mm (0.0098 inch) undersize bearing. For identification of undersize
bearing, it is painted red at the position as indicated in figure, undersize bearing thickness is 1.605 - 1.615 mm (0.0632 - 0.0635 inch) at the center
of it.
