Specs At A Glance

Good To Know

Q: What does a complete crankshaft assembly include? A: It ships as a crankshaft with connecting rods already matched to it, so the rotating assembly can be installed as one unit during a rebuild.

Q: Should I have this installed by a professional? A: Crankshaft replacement requires splitting the engine cases and precise torque sequencing, so professional installation is recommended for correct bearing clearances.

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