Engine Crankshaft Main Bearing Set

Engine Crankshaft Main Bearing Set from Evergreen

Engine crankshaft main bearing sets support the crankshaft in the block and maintain the oil film that keeps the crank from contacting the block. A complete set replaces every upper and lower main shell, plus the thrust bearing where the design uses one.

When to Replace

Low oil pressure, especially at hot idle
Deep knocking that rises with engine load
Scored or wiped bearings found during teardown

Installation Tips

Measure crankshaft journals to confirm standard or undersize bearings
Check oil clearance with a bore gauge or plastigage
Keep bearing backs and housing bores clean and dry
