Product Overview — Part 3128 3175 50
The 3128 3175 50 is a precision-manufactured BOMAG Cab Mounts component. The 3128 3175 50 is a BOMAG cab suspension element providing primary vertical compliance for BW series compactor cab mounting systems. Unlike the 3128 0458 series point mounts, this suspension element may serve as a larger-format cab suspension component handling higher static and dynamic loads. Engineered to BOMAG's precise specifications, this element uses a rubber compound with carefully controlled load-deflection characteristics. The rated static deflection under cab weight must be within tolerance to ensure correct cab height and mounting bolt engagement at installation. For complete BOMAG BW series cab mounting system components, see our BOMAG cab mount catalog which covers the full 3115 and 3128 series. Contact our technical team with the BOMAG serial number for confirmation of the correct specification for your machine.

Installation Guidelines
- Inspect on arrival: Verify part number 3128 3175 50. Check for transit damage — reject any non-conforming component.
- Clean mating surfaces: Remove all rust, old rubber fragments, grease, and paint before installation.
- Align correctly: Follow assembly drawing orientation. Incorrect orientation may cause premature failure.
- Torque fasteners: Use calibrated torque wrench and cross-pattern tightening sequence per OEM specification.
- Post-install check: Inspect for correct seating. Run equipment at low speed to verify no abnormal noise or vibration.
