Good To Know

Q: How many main bearings does a crankshaft service usually need? A: Main bearings are typically replaced as a set during a bottom end rebuild, so confirm the quantity required for the 1503 engine before ordering. A: Inspect the crank journals at the same time, since worn journals can damage a new bearing.

Q: Can this bearing be fitted without splitting the cases? A: Main bearing replacement on the 1503 engine normally requires splitting the crankcase and removing the crankshaft. A: That makes it a job best handled with the correct service manual and torque specs on hand.

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