Good To Know

Q: Does this crankshaft come as a complete assembly? A: Yes, it ships as a complete crankshaft assembly with connecting rods installed, so the bottom end can be built without sourcing rods separately.

Q: Should the engine case be checked before installation? A: Yes, always inspect the crankcase, oil passages, and bearing surfaces for wear before fitting a new crankshaft assembly to prevent repeat damage.

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