The Bomag 09181214 Fitting Key is a genuine OEM component designed for the BMP 851 and BW 85 T trench compactors. Sourced directly from Bomag, this part matches the original specification exactly, ensuring a correct, secure installation without guesswork. It is engineered to fit these machines as designed, making it the dependable choice when servicing or rebuilding the drivetrain or power transfer assembly on your trench compactor.
Key Features
- Genuine OEM Precision — manufactured to Bomag's exact tolerancing for proper key-to-shaft engagement, eliminating the play or misalignment that can result from an imprecise fit
- Direct Replacement — slots into the keyed shaft interface exactly as the original, requiring no filing, shimming, or modification to seat correctly
- Confirmed Trench Compactor Fitment — verified for the BMP 851 and BW 85 T trench compactors, so you can order with confidence knowing this is the correct part for your machine
- Protects Shaft and Hub Integrity — a correctly fitted key prevents rotational slippage between shaft and driven component, protecting both surfaces from the fretting and scoring that a worn or undersized key causes
- Torque Transfer Reliability — restores full, consistent power transmission across the keyed connection, keeping the drivetrain performing as designed under the demanding load cycles of compaction work
A fitting key is a small but critical component that locks a rotating shaft to a hub, gear, pulley, or drum, ensuring both parts turn together as a single unit. Without a properly sized and seated key, the driven component can slip on the shaft under load, causing rapid wear to both mating surfaces and leading to loss of drive power or complete component failure. On trench compactors like the BMP 851 and BW 85 T, where reliable power transmission is essential to effective compaction, replacing a worn or damaged key promptly keeps the drivetrain working as intended and prevents more costly damage to the shaft or hub.
