Main bearing (cont'd)
- 3Measure inside diameter "A" of main bearing.
SEM174B - 4Measure outside diameter "Dm" of main journal in crankshaft.
SEM506A - 5Calculate main bearing clearance. Main bearing clearance = A - Dm
Connecting rod bearing
- 1Install connecting rod bearing to connecting rod and cap.
- 2Install connecting rod cap to connecting rod.Apply oil to the thread portion of bolts and seating surface of nuts.
- 3Measure inside diameter "C" of connecting rod.
SEM507A - 4Measure outside diameter "Dp" of pin journal in crankshaft.
- 5Calculate connecting rod bearing clearance. Connecting rod bearing clearance = C - Dp
Method B (Using plastigage)
CAUTION
Do not turn crankshaft or connecting rod while plastigage is being inserted. When bearing clearance exceeds the specified limit, ensure that the proper bearing has been installed. Then if excessive bearing clearance exists, use a thicker main bearing or undersized bearing so that the specified bearing clearance is obtained.
