Crankshaft & Main Bearings
- Before installing main bearings, hold a straightedge across threads of main bearing cap bolts. Ensure main bearing cap bolt threads contact straightedge in all areas. If threads fail to contact straightedge, bolts are stretched and must be replaced.
- Apply light coat of engine oil to threads before tightening bolt to specification. See TORQUE SPECIFICATIONS .
NOTE:
Measure cylinder bore at normal room temperature of 70°F (21°C).
