CRANKSHAFT
Crankshaft Inspection
- 1Check crankshaft journals and pins for score, bias, wear or cracks. If faults are minor, correct with fine crocus cloth.
- 2Check journals and pins with a micrometer for taper and out-of-round. Out-of-round (X - Y): Less than 0.005 mm (0.0002 in). Taper (A - B): Less than 0.005 mm (0.0002 in).
SEM316A - 3Check crankshaft runout. Runout (Total indicator reading): Less than 0.05 mm (0.0020 in).
