Product Overview — Part 3115 9150 99
The 3115 9150 99 is a precision-manufactured BOMAG Scraper Parts component. The 3115 9150 99 is a BOMAG rubber buffer element for BW series compactor and scraper travel limit and impact stop applications. This component absorbs kinetic energy at machine travel extremes, protecting structural members from metal-to-metal contact that causes noise, vibration, and structural fatigue cracks. The buffer's rubber compound uses high-energy-absorption carbon black loaded NR/SBR blend, providing a deflection-force curve that maximizes energy absorption before reaching maximum rated deflection. This characteristic distributes the impact load over time, reducing peak force on structural members. Part 3115 9150 99 is part of our comprehensive BOMAG scraper parts catalog. Related buffer parts 3128303930 and 26337508 cover similar applications with different dimensional specifications.

Installation Guidelines
- Inspect on arrival: Verify part number 3115 9150 99. 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.
