Product Overview — Part 227-0172
The 227-0172 is a precision-manufactured Vibration Dampers component. The 227-0172 rubber isolator mount provides vibration isolation for Caterpillar construction equipment engine and cab mounting systems. This component uses a cylindrical rubber-to-metal bonded design providing both load-bearing capacity and multi-directional vibration attenuation. Engineered to CAT isolation requirements, part 227-0172 uses a natural rubber compound with anti-ozonant and antioxidant additives for extended outdoor service life typical of North American construction site conditions. The metal insert material and surface treatment are selected for compatibility with CAT mounting systems. This component is cross-referenced against our vibration damper catalog. For BOMAG compactor applications with similar isolation requirements, see 3115 2472 00 and 3128047510.

Installation Guidelines
- Inspect on arrival: Verify part number 227-0172. 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.
