Good To Know

Q: How many main bearings does a rebuild normally need? A: The count depends on your specific 1503cc crankshaft layout, so check the service manual and order the full set your rebuild requires. Replacing them as a matched set is standard practice whenever the bottom end is opened.

Q: Should main bearings be replaced in pairs or sets? A: Main bearings should be replaced as a complete set for even load distribution across the crankshaft. Installing one new bearing alongside worn ones can lead to uneven wear 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.
