Good To Know

Q: How do I know if my crankshaft main bearing needs replacing? A: Common signs include knocking or rumbling from the bottom end, low oil pressure, and metal debris in the oil. Any of these during a rebuild points to inspecting and replacing the bearing.

Q: Should I replace all main bearings at once? A: When one crankshaft main bearing shows wear, replacing the set together helps keep clearances even across the crankshaft. Confirm the correct size for your engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
