Good To Know

Q: Does this shaft come with the gear attached? A: Yes, the drive gear is fitted to the shaft as a single assembly for direct installation. Q: What else should I replace at the same time? A: Inspect the seal, bearing, and impeller for wear and replace them alongside the shaft to avoid repeat teardown.

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