Good To Know

Q: How many main bearings does a crankshaft rebuild need? A: The count depends on your 1503 crank layout, so confirm the quantity in the service manual before ordering. Get the exact number your rebuild requires.

Q: Should I replace bearings in sets? A: Replacing all main bearings together during a rebuild helps keep clearances even. Mixing worn and new bearings can cause 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.
