Good To Know

Q: How many main bearings does a 1503 crankshaft use? A: A 1503 crankshaft uses multiple main bearings, so check your service manual to confirm how many you need for the job before ordering.

Q: Should main bearings be replaced as a set? A: Main bearings are normally replaced together during a bottom end rebuild, and clearances should be measured after installation.

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