The Bomag 09190504 Woodruff Key is a genuine OEM component designed for a range of Bomag single drum rollers, refuse and landfill compactors, and recycler/stabilizer equipment. Sourced directly through Bomag's OEM supply chain, this Woodruff Key delivers the exact geometry needed for correct shaft-to-hub engagement across compatible machines. This part fits the BW 142 D-2 single drum roller, BC 601 RS, BC 601 RB, BC 672 RB, BC 772 RB, BC 772 RS, BC 972 RB, and BC 1172 RB refuse and landfill compactors, as well as the MPH 122 recycler/stabilizer. When this small but critical component wears or shears, prompt replacement with a correctly dimensioned key is essential to restoring dependable power transfer.
Key Features
- OEM-Exact Geometry — Manufactured to Bomag's original dimensional specification, ensuring correct keyway engagement without modification to the shaft or hub.
- Direct Drop-In Replacement — Seats into the existing keyway slot as the factory original did, simplifying installation during routine drivetrain service.

- Torque Transmission Integrity — Maintains positive rotational drive between shaft and hub, preventing slippage that can cause accelerated wear or component damage under compaction loads.
- Genuine OEM Part — Supplied as authentic Bomag stock under part number 09190504, carrying the confidence of manufacturer traceability and correct material grade.
A Woodruff Key is a small, semicircular metal key that fits into a curved slot milled into a shaft, aligning and locking a hub, sprocket, pulley, or gear in the correct rotational position. It transmits torque between the rotating shaft and the mounted component, preventing relative movement under load. When a Woodruff Key shears or wears — often caused by shock loads or improper installation — the connected component can slip or spin freely on the shaft, resulting in loss of drive, damaged keyways, and potential failure of surrounding drivetrain components.
