The Bomag 05821438 Key is a genuine OEM replacement built for Bomag BC-series refuse/landfill compactors and soil compactors, including the BC 672 RB, BC 772 RB, BC 972 RB, and BC 1172 RB among others. Sourced directly from Bomag, this key delivers the exact fit and material spec required for correct operation on every covered machine. It is also compatible with BC 772 EB-2 and BC 672 EB-2 soil compactors, giving it broad coverage across the BC heavy compactor lineup. When a worn or damaged key is left in service, it can compromise the drive connection it supports — swapping it out with the correct OEM part keeps the drivetrain secure and the machine running as designed.
Key Features
- Genuine OEM Material and Dimensional Accuracy — machined to Bomag's exact hardness and dimensional tolerances so the key seats fully in its keyway without play or deformation under load
- Direct Drop-In Replacement — matches the original profile and length for straightforward installation with standard hand tools; no filing, shimming, or rework needed
- Broad BC-Series Coverage — fits BC 672, BC 772, BC 972, and BC 1172 refuse/landfill compactors across multiple generation variants (RB, RS, RB-2 through RB-4, RS-2 through RS-4), plus BC 672 EB-2 and BC 772 EB-2 soil compactors
- Drivetrain Integrity — a correctly fitted key locks rotating components to their shaft, preventing slippage that would otherwise accelerate wear on both the shaft and the mating hub
- Verified Bomag Part Number — ordering by part number 05821438 confirms you are receiving the correct key for your specific machine generation, eliminating guesswork on a part where an incorrect fit causes immediate mechanical damage
A key is a small, precisely shaped component that fits into matching slots — called keyways — cut into a shaft and a mating hub or gear. Its role is to lock the two components together rotationally so that torque is transferred from one to the other without slippage. On heavy compactors like the BC-series machines, drivetrain components operate under sustained high-torque loading, making the condition of every key in the system critical. When a key shears, deforms, or works loose, the shaft and hub begin to rotate independently, rapidly damaging both components and potentially causing loss of drive to the affected system.
