The Bomag 05114817 Sun Gear Shaft is a genuine OEM component designed for BC 972 RB and BC 1172 RB series refuse and landfill compactors. Sourced directly from Bomag, this sun gear shaft meets the exact dimensional and material standards of the original factory part, ensuring a correct installation with no guesswork. This component is compatible across multiple generations of the BC 972 RB and BC 1172 RB, including the RB-2, RB-3, and RB-4 variants, making it the right choice for operators maintaining any machine in that compactor family.
Key Features
- Genuine OEM Gear Precision — manufactured to Bomag's exact hardness and dimensional tolerances for planetary drive components, ensuring proper load transfer through the gear train
- Direct-Fit Replacement — engineered to the same shaft geometry and spline specification as the original, allowing straightforward installation into the planetary drive assembly
- Broad Generation Coverage — fits BC 972 RB, BC 972 RB-2, BC 972 RB-3, BC 972 RB-4, BC 1172 RB, BC 1172 RB-2, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors
- Drive System Integrity — a worn or damaged sun gear shaft causes uneven torque distribution and accelerated wear on surrounding planetary components; replacing it promptly restores full drivetrain efficiency
- Verified Part Number — order with confidence using Bomag part number 05114817, cross-referenced to the correct assembly position in the Bomag catalog
The sun gear shaft is a core element of the planetary gear set within the compactor's drive system. It transmits rotational torque from the input to the planetary gears, which then distribute drive force to the wheel ends — enabling the heavy pushing and compacting work these BC-series refuse compactors are built for. When the sun gear shaft wears, cracks, or loses its spline integrity, the planetary assembly loses the ability to transfer power efficiently, resulting in sluggish drive response, unusual driveline noise, and potential for cascading damage to surrounding gear components.
