Specs At A Glance

Good To Know

Q: Does this assembly include the connecting rods and bearings? A: Yes, a complete crankshaft assembly ships with the crank, rods, and bearings as one unit for the 1503 engine.

Q: Can I install this without splitting the cases? A: No, crankshaft replacement on the 1503 platform requires splitting the crankcase, so plan for a full teardown.

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