Good To Know

Q: How many main bearings does a crankshaft rebuild need? A: Count depends on the crank layout of your 1503 engine, so check the service manual for the exact quantity. Order the number your rebuild calls for.

Q: Should I replace bearings in sets? A: Replacing all main bearings at once is common practice during a rebuild to keep clearances even. Mixing worn and new bearings can lead to uneven wear.

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