Specs At A Glance

Good To Know

Q: Does this kit include all the parts needed for the crank rebuild? A: A connecting rod kit typically covers the rod assembly, and crank bearings and seals are usually ordered separately, so check your parts list before ordering.

Q: Can I install this without splitting the cases? A: Replacing a connecting rod requires the crank to be removed and pressed apart, which means splitting the cases on this engine.

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