Crankshaft Main Bearing: Service and Repair
MAIN BEARING CLEARANCE
1. Remove bearings and inspect the main bearing bores for damage or abnormal wear.
2. Measure main bearing bore diameter (1) after tightening main bearing cap bolts to 176 Nm (130 ft. lbs.). See Main Bearing Bore Diameter table
for specifications.
3. Install the crankshaft main bearings and measure main bearing bore diameter with the main bolts tightened to 176 Nm (130 ft. lbs.). See Main
Bearing Bore Diameter table for specifications.
MAIN BEARING BORE DIAMETER
4. Measure the diameter of the crankshaft main journal at the locations shown. Calculate the average diameter for each side of the journal.
5. Calculate the main bearing journal to bearing clearance. Maximum clearance is 0.119 mm (0.00475 inch). If the crankshaft journal is within limits,
replace the main bearings. If not within limits, grind the crankshaft to next size and use oversize bearings. See Crankshaft Main Journal Diameter
table for specifications.
6. Measure thrust distance at the No.6 position.
