Good To Know

Q: How many main bearings does the 1503 engine need? A: The 1503 bottom end uses multiple main bearing positions, so check your service manual and order the quantity your rebuild requires.

Q: Should main bearings be replaced during a rebuild? A: It is common practice to replace main bearings whenever the crankshaft is removed, since worn bearings can cause vibration and premature failure.

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