Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's original hardness and dimensional specification, ensuring the key seats correctly in the keyway without deforming under load.
- Drop-In Shaft Alignment — The Woodruff profile registers precisely into the shaft and hub keyway, allowing correct installation without filing or fitting.
- Confirmed Roller Fitment — Verified for use on R2000H, V305EH, and V305EK Multiquip roller models.
- Torque Transmission Integrity — A properly seated Woodruff key maintains positive drive engagement between the shaft and mating component, preventing slippage that can cause premature wear or loss of drum drive.
- Direct OEM Replacement — Part number 491759 matches the original component specification, so installation follows the same procedure as the factory-fitted key.
A Woodruff key is a small semicircular drive key that fits into a curved keyway machined into a shaft, locking a gear, pulley, or hub in place so that torque is transferred evenly without rotation or slippage between the two components. On roller equipment, the Woodruff key plays a critical role in maintaining positive engagement between the engine or drive shaft and the drum or transmission assembly. When a Woodruff key shears or wears, the mating component can spin freely on the shaft, causing loss of drive, vibration, or component damage that takes the machine out of service.
