Product Overview — Part 17A-54-46130
The 17A-54-46130 is a precision-manufactured Cab Mounts component. The 17A-54-46130 front cab mount rubber is engineered for Komatsu excavator front cab attachment positions. This component provides directional vibration isolation at forward cab mounting points where boom and dipper arm dynamic forces create complex multi-axis loading conditions. The rubber compound is formulated with reinforced natural rubber providing sufficient stiffness to control cab motion under aggressive digging operations while remaining compliant enough for low-frequency vibration attenuation. Companion part to 17A-54-46120 for complete front cab mount kit. For BOMAG equipment with similar cab mounting geometry, our 3128 0458 series offers comparable isolation performance. We maintain dimensional records for cross-verification on request.

Installation Guidelines
- Inspect on arrival: Verify part number 17A-54-46130. 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.
