The Bomag 42040109 Axle Support is a genuine OEM component designed for a broad range of Bomag single drum rollers, refuse/landfill compactors, and recycler/stabilizers. Sourced directly from Bomag, this part meets the exact specifications of the original, ensuring a true OEM-grade replacement across every compatible machine. This axle support is confirmed to fit models including the BW 216 D-3, BW 216 DH-3, BW 219 DH-3, BW 219 PDH-3, BW 219 D-4, BW 219 PD-4, BW 219 DH-4, BW 219 PDH-4, BW 220 D-4, BW 225, BW 225 D-3, BW 226 DH-4, BW 226 PDH-4, 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, BC 1172 RB-4, MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 460, RS460 STAGE V, RS 500, and RS 650. When a worn or damaged axle support threatens your machine's structural integrity, replacing it with the correct OEM part is the only reliable path to restoring full operational capability.
Key Features
- Genuine OEM Structural Integrity — manufactured to Bomag's exact load-bearing tolerances, ensuring the axle support carries operating stresses without deflection or premature wear
- Direct OEM Replacement — installs in the original mounting position with OEM hole patterns and interface geometry, requiring no reworking of surrounding components
- Broad Cross-Family Fitment — verified for Bomag BW 216, BW 219, BW 220, BW 225, and BW 226 single drum rollers, BC 972 RB and BC 1172 RB refuse/landfill compactors, and MPH 121, MPH 122, MPH 125, MPH 600, RS 460, RS 500, and RS 650 recycler/stabilizers
- Sustained Axle Alignment — a correctly fitted axle support maintains proper axle positioning under dynamic compaction loads, preventing uneven drum or wheel wear and protecting drivetrain components
- Long-Term Structural Confidence — OEM-grade material and dimensional accuracy mean this support resists the fatigue cycling inherent to heavy compaction and landfill operation cycles
The axle support is a structural mounting component that locates and braces the axle assembly within the machine's frame. It bears the static weight of the machine as well as the dynamic forces generated during compaction passes, keeping the axle correctly aligned relative to the drum or wheels. When this component cracks, deforms, or wears at its mounting interfaces, axle misalignment follows — leading to accelerated tire or drum wear, vibration, and potential damage to adjacent drivetrain and frame components. Replacing a failed axle support with a genuine Bomag part, such as part number 42040109, restores the correct load path and protects the broader axle assembly from secondary damage.
