The Bomag 09180403 Fitting Key is a genuine OEM component designed for a range of Bomag compaction equipment, including the BMP 851 trench compactor, BW 55 E walk-behind roller, and BPR-series reversible vibratory plates including the BPR 25/32, BPR 25/40, BPR 30/38, BPR 30/38 D, BPR 50/55 D, and BPR 75/60 D. Sourced directly from Bomag, this fitting key matches the original specification for a clean, accurate installation without guesswork. When a fitting key wears or goes missing, it can compromise the secure connection of shaft-mounted components — making prompt replacement with the correct OEM part essential. DHS Equipment stocks part number 09180403 to keep your Bomag equipment running as it should.
Key Features
- OEM-Grade Material and Tolerancing — Manufactured to Bomag's original specification, this fitting key delivers the precise dimensional tolerances needed to seat shaft components securely and transmit torque without slippage.
- Direct Drop-In Replacement — Machined to match the original keyway geometry, this part slots into position without modification, restoring the connection between mating components exactly as designed.
- Broad Compaction Equipment Coverage — Fits the BMP 851 trench compactor, BW 55 E walk-behind roller, and BPR 25/32, BPR 25/40, BPR 30/38, BPR 30/38 D, BPR 50/55 D, and BPR 75/60 D reversible vibratory plates.
- Torque Transfer Integrity — A correctly installed fitting key locks rotating components to their shafts, ensuring full power transfer from the drive to compaction elements. A worn or missing key allows slippage that can rapidly damage both the shaft and the hub.
- Genuine Bomag OEM Part — Carrying Bomag's authentic part number 09180403, this component meets the same standards as the original part installed at the factory, giving you confidence in long-term fit and function.
A fitting key — sometimes called a woodruff key or drive key depending on its profile — is a small but critical component that locks a rotating shaft to a mating hub, pulley, or gear. It sits in matching keyways cut into both parts, preventing relative rotation and ensuring that drive force is transferred cleanly and completely. When a fitting key shears, wears down, or is lost during service, the connected component can spin freely on the shaft, causing rapid wear on the keyway surfaces and potential failure of the assembly. Replacing a damaged or missing fitting key promptly with the correct OEM part is one of the simplest and most cost-effective ways to protect the drivetrain components around it.
