Product Overview — Part 3128 0458 24
The 3128 0458 24 is a precision-manufactured BOMAG Cab Mounts component. The 3128 0458 24 firm-compound (24 Shore A) BOMAG cab mount is specified for BOMAG compactor applications where cab stability takes priority over maximum vibration isolation. The 24 Shore A hardness provides higher lateral and vertical stiffness, reducing cab displacement under operator loads and machine acceleration. This mount is recommended for BOMAG compactors operating on slopes, uneven terrain, or in conditions where excessive cab movement would compromise operator control or create safety concerns. The firmer compound also provides longer service life in high-deflection applications where softer compounds would fatigue prematurely. Also sold under the consolidated part number 3128045824 (same part, digits without spaces). See the complete BOMAG cab mount selection guide comparing 3128 0458 15 (soft), 3128 0458 18 (medium), and this 24 Shore A firm variant.

Installation Guidelines
- Inspect on arrival: Verify part number 3128 0458 24. 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.
