Product Overview — Part 11N6-13060
The 11N6-13060 is a precision-manufactured Rubber Parts component for demanding industrial and transportation applications. Matched engine mounting rubber set (OEM 11N6-13060 + 11N6-13065) for Hyundai R290LC-7, R305LC-7, and R320LC-7 large excavators. This 30-to-40-ton class is widely deployed on US infrastructure and earthmoving projects. Replacing worn engine mounts restores cab comfort, reduces structural stress on the mainframe, and prevents costly damage to turbocharger and exhaust connections caused by excessive engine movement.
Produced in our ISO 9001:2015 certified facility using advanced vulcanization processes and carefully selected elastomer compounds, part 11N6-13060 meets the exacting requirements of original equipment manufacturers and aftermarket service providers. Every unit undergoes dimensional verification, hardness testing, and visual inspection before release for shipment to customers in the United States, Canada, Europe, and Asia-Pacific.

- Protection Additives: Anti-ozonant wax and chemical antioxidant system for extended service life
- Bonding System: Chemically bonded rubber-to-metal interface exceeding bulk rubber strength
- EN 45545-2 Option: Halogen-free flame retardant meeting smoke toxicity requirements (railway grade)
Every batch produced under ISO 9001:2015 QMS with full material traceability. Certificates of conformance and material test reports available upon request.
Installation Guidelines
- Inspect on arrival: Verify part number 11N6-13060. Check for transit damage or surface defects — reject any visually non-conforming component.
- Clean mating surfaces: Remove all rust, old rubber fragments, grease, and paint. Flat tolerance within 0.5 mm.
- Align correctly: Follow assembly drawing orientation. Incorrect orientation can cause premature failure.
- Torque fasteners: Use calibrated torque wrench and cross-pattern tightening sequence per OEM specification.
- Post-install check: Visual inspection for correct seating. Run equipment at low speed to verify absence of abnormal noise or vibration.
