Product Overview — Part 195-54-78410
The 195-54-78410 is a precision-manufactured Cab Mounts component. Part 195-54-78410 is a heavy-duty cab isolation mount for Komatsu D-series bulldozer cab systems. Dozer operations generate significantly higher track-induced vibration than excavator applications, making the rubber compound selection and bonding system critical for this application. Manufactured with a high-fatigue-life rubber compound, part 195-54-78410 is tested to simulate multi-million cycle life under representative dozer vibration profiles. The steel insert bonding system uses chemical primer and vulcanization bonding to ensure metal-rubber interface integrity under peak shock loads. Our supply includes dimensional verification against Komatsu D51, D61, D65, D85, and D155 dozer specifications. Compare with 56B-50-12315 for alternative Komatsu dozer cab mount options.

Installation Guidelines
- Inspect on arrival: Verify part number 195-54-78410. 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.
