Specs At A Glance

Good To Know

Q: How many main bearings does a rebuild usually need? A: Most bottom-end rebuilds replace the full set of main bearings at once, so confirm the quantity required for your engine before ordering. A: Bearing fit is matched to the crankshaft journal size, so measure the journals during teardown.

Q: Can I install this without splitting the cases? A: Crankshaft main bearings sit inside the crankcase, so the engine cases must be split for replacement. A: Have the crankshaft inspected and any damaged journals addressed before reassembly.

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