The Wacker Neuson Woodruff Key is a genuine OEM component designed for the P31A Power Unit for Wet Screed. As a factory-sourced part, it is manufactured to the exact tolerances required for proper shaft-to-hub engagement in this power unit application. Confirm your model number against the P31A fitment before ordering to ensure a direct, correct installation.
Key Features
- Genuine OEM Tolerancing: — Sourced directly from Wacker Neuson, this Woodruff Key is produced to the precise dimensional spec required for correct seating in the keyed shaft assembly — no guesswork on fitment.
- Exact Shaft-to-Hub Alignment: — The semi-circular profile seats fully into the shaft keyway, ensuring the mating hub or pulley locks at the correct rotational position every time.
- Verified P31A Compatibility: — Confirmed fitment for the P31A Power Unit for Wet Screed, so you can order with confidence that this is the correct key for your machine.
- Protects Driven Components: — A correctly seated Woodruff Key prevents relative rotation between shaft and hub under load, protecting both the shaft and the driven component from wear and slippage damage.
- Fast Serviceability: — A small part that plays a critical role; having the correct OEM replacement on hand keeps your wet screed power unit back in service without delay caused by incorrect substitutes.
A Woodruff Key is a small, semi-circular metal key that fits into a matching slot machined into a rotating shaft, with the flat edge engaging a corresponding keyway in a hub, gear, or pulley. Its purpose is to lock the two components together rotationally so that torque is transmitted cleanly from the shaft to the driven part. When a Woodruff Key shears, wears, or goes missing, the hub or pulley can slip or spin freely on the shaft, causing a complete loss of power transmission and potential damage to both the shaft and the mating component. Replacing it promptly with the correct OEM part restores proper drive engagement and prevents further mechanical damage.
