Check crankshaft (Figure 2, Item 6), journal surfaces (Figure 2, Items 7 and 4) and oil passages
(Figure 2, Item 8) for cracks using magnetic particle inspection or equivalent. Replace crankshaft if damage
Check crankshaft (Figure 2, Item 6) for discoloration, excessive wear and pitting. Replace crankshaft if wear
or pitting is found.
Check all journal surfaces (Figure 2, Items 7 and 4) for scoring and discoloration. Replace crankshaft if
scoring or discoloration is found.
If scoring, grooving or excessive wear exists, this may cause leakage.The seal contact
surface may be sleeved and an oversize seal may be installed.
Check oil seal contact surface (Figure 2, Item 3) for scoring, grooving or excessive wear.
Measurements of the crankshaft should be accurate to the nearest 0.0002 in.
Measure crankshaft thrust washer surfaces (Figure 2, Item 2) for excessive wear or grooving. Replace
crankshaft if out of tolerance.
