Good To Know

Q: How many main bearings does this job need? A: Main bearing count depends on the crankshaft layout of the 1503 engine, so confirm the number your rebuild requires before ordering and inspect every bearing position during teardown.

Q: What should I check before installing a main bearing? A: Verify crankshaft journal condition and measure clearances against spec, since a worn or damaged journal will shorten the life of any new crankshaft main bearing.

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