Good To Know

Q: Is this a genuine OEM crankshaft? A: This is a complete crankshaft assembly made for the 1503 engine platform and is not an original brand part. Confirm your engine code and model year before ordering.

Q: Can I install this without machining the cases? A: Installation should follow the service manual for your model, and case inspection is recommended during any crankshaft replacement. Always verify clearances and torque specs during assembly.

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