The Bomag 33180251 Woodruff Key is a genuine OEM Woodruff Key designed for BT 65 and BT 70 tampers. Sourced directly from Bomag, this part meets the exact material and dimensional standards of the original component installed at the factory. This Woodruff Key fits both the BT 65 and BT 70 tamper models, giving operators and service technicians a straightforward, correctly specified replacement. When a Woodruff Key shears or wears, getting the right OEM part back in place fast is critical to restoring full compaction performance.
Key Features
- Genuine OEM Specification — machined to the exact hardness and dimensional tolerances required for correct shaft-to-hub engagement on Bomag tampers, eliminating the guesswork of cross-referencing aftermarket alternatives.
- Direct Slot-In Replacement — sized to drop into the existing keyway on the crankshaft or drive shaft without any modification, restoring the precise rotational lock between components.
- Confirmed Tamper Fitment — part number 33180251 is verified for the BT 65 and BT 70 tampers, covering both models in this Bomag rammer series.
- Protects Shaft and Hub Integrity — a correctly fitted Woodruff Key prevents fretting, slippage, and progressive keyway wear that can lead to costly shaft or hub replacement if left unaddressed.
- Safety-Critical Drive Connection — the Woodruff Key is the mechanical link that keeps the drive assembly synchronized; a failed or missing key can cause sudden loss of compaction drive, creating an unsafe condition for the operator.
A Woodruff Key is a small, semi-circular metal key that seats into a curved slot machined into a shaft, with the top of the key engaging a corresponding groove in the mating hub or gear. Its job is to lock two rotating components together so they turn as a single unit, preventing the hub from spinning independently on the shaft. When a Woodruff Key shears or is lost, the driven component — whether a flywheel, clutch, or drive gear — can slip or freewheel entirely, resulting in lost compaction force and potential damage to surrounding shaft surfaces.
