Product Overview — Part 3128 0458 15
The 3128 0458 15 is a precision-manufactured BOMAG Cab Mounts component. The 3128 0458 15 is the soft-compound (15 Shore A) variant of the BOMAG cab mount series, providing maximum vibration isolation for BOMAG BW series compactors used in asphalt compaction where vibration levels are highest. The number 15 denotes the rubber hardness in Shore A units — the softest of the three standard BOMAG cab mount options. Soft 15 Shore A mounts deliver the highest isolation efficiency at drum vibration frequencies (typically 40–67 Hz for BOMAG asphalt compactors) but allow greater static cab displacement under machine tilt or acceleration. This mount is recommended for operators prioritizing vibration comfort in high-frequency compaction operations. Available variants: - 3128 0458 15 — Soft (15 Shore A) — Maximum isolation - 3128 0458 18 — Medium (18 Shore A) — Balanced performance - 3128 0458 24 — Firm (24 Shore A) — Stability priority All three variants are dimensionally identical and interchangeable within the BOMAG cab mount housing. Shore hardness selection depends on equipment model, operating weight, and application.

Installation Guidelines
- Inspect on arrival: Verify part number 3128 0458 15. 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.
