17A-54-46130 Komatsu Rubber Cushion Mount — PC200 & PC300 Excavator Companion Mount
OEM-Equivalent • ISO 9001:2015 Certified • Komatsu PC200-8 • In Stock
Product Overview
The 17A-54-46130 is the companion engine mount to the 17A-54-46120 in Komatsu's PC-series hydraulic excavator powerplant mounting system. While the 17A-54-46120 supports the engine at one set of mounting positions, the 17A-54-46130 secures a different mount point — typically at the rear or transmission side of the powerplant assembly. Together, these two part numbers form the complete engine isolation system that prevents powertrain vibrations from reaching the excavator's revolving frame.
The 17A-54-46130 is engineered with the same premium natural rubber compound used across Komatsu's anti-vibration mount range, but its geometry and internal reinforcement structure are specific to its mounting position. The asymmetric loading profile at the transmission end of the engine — where torque converter pulsations combine with engine firing impulses — demands different stiffness characteristics compared to the front mount position. This is why the 17A-54-46120 and 17A-54-46130 cannot be used interchangeably.
For a complete engine mount replacement on PC200 through PC350 excavators, Komatsu's service documentation calls for replacing all engine mounts simultaneously. This ensures uniform vibration isolation across all mounting points and prevents the uneven load distribution that occurs when new mounts are paired with worn ones.

Maintenance & Expected Lifespan
Under standard operating conditions, the 17A-54-46130 has an expected service life of 5,000 to 10,000 operating hours. In severe duty applications (24/7 mining, extreme temperatures, high dust), service life may be reduced. Inspect at every major service interval (2,000 hours) for surface cracking, compression set, oil contamination, and mounting hardware integrity.
Replacement criteria: Replace when surface cracks exceed 2 mm depth, compression set exceeds 30%, rubber shows oil swelling, or the operator reports increased vibration. Always replace all mounts simultaneously for optimal isolation performance.
