The Multiquip 0053204201 is a genuine OEM Woodruff Key (Half Moon) 4mm x 5mm x 12mm designed for Multiquip rammer models including the MT-E55, MTR40HF, MT85, and MT60H2. As a factory-sourced component, it meets the exact dimensional tolerances required for proper shaft and hub alignment on these machines. Sourcing a genuine OEM key ensures the correct fit into the keyway without play or misalignment that could damage rotating components. DHS Equipment stocks this part to keep your rammer running as it should.
Key Features
- Exact Dimensional Spec: — Measures 4mm x 5mm x 12mm to match the original keyway geometry on Multiquip rammer crankshafts and drive components precisely.
- Genuine OEM Component: — Sourced directly from Multiquip, this key is manufactured to the same material hardness and half-moon profile as the part it replaces.
- Broad Rammer Compatibility: — Confirmed fitment for MT-E55, MTR40HF, MT85, and MT60H2 rammers, covering both standard and trench rammer configurations in the Multiquip lineup.
- Correct Torque Transfer: — A properly seated Woodruff key locks the hub or gear to the shaft, ensuring full torque is transmitted without slippage during compaction strokes.
- Drop-In Replacement: — The half-moon profile seats directly into the existing keyway slot with no filing or reshaping required, making field replacement straightforward.
A Woodruff key is a small semi-circular metal key that fits into a matching slot machined into a shaft and hub, locking the two together so they rotate as one unit. In a rammer, this key is critical to maintaining the connection between the crankshaft and drive components that generate the machine's compaction stroke. When a Woodruff key shears or wears, the shaft and hub lose their positive drive connection, causing slippage, erratic performance, or complete loss of function — making prompt replacement essential to restore normal operation.
