Product Overview — Part 55159454
The 55159454 is a precision-manufactured Cab Mounts component. Part 55159454 is a cab isolation rubber mount for Case and CNH construction equipment, providing direct replacement for the OEM cab mount at Case excavator and wheel loader cab attachment points. Dimensional and compound properties match the original specification. This component uses a natural rubber compound with anti-ozonant and antioxidant protection for extended outdoor service life. The bonded rubber-to-metal construction provides the load capacity required for Case equipment cab weights while maintaining low-frequency vibration isolation performance. Complete Case cab mount kit may require multiple identical or paired mounts. Contact our technical team with the Case model number and machine serial number for confirmation of mount count and any hardness variants. Related parts 55017281 and 55154977 cover the full Case cab mount range we supply.

Installation Guidelines
- Inspect on arrival: Verify part number 55159454. 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.
