20E-54-K1360 Komatsu Engine Mount — PC160LC & PC170LC Excavator
OEM-Equivalent • ISO 9001:2015 Certified • Komatsu PC160LC-8 • In Stock
Product Overview
The 20E-54-K1360 is a rubber engine mount designed for Komatsu PC160LC and PC170LC excavators in the 16-17 tonne weight class. These mid-compact machines bridge the gap between the compact PC78/PC88 class and the standard PC200 class, making them popular for urban construction, road building, and utility work where a 20-tonne machine would be too large.
The 20E-54-K1360 isolates the SAA4D107E-1 four-cylinder engine from the revolving frame. The four-cylinder engine produces different vibration characteristics compared to the six-cylinder units in larger machines — with more pronounced second-order vibrations that the mount's compound formulation is specifically tuned to attenuate.
The PC160LC/PC170LC is increasingly popular in European and North American urban construction markets where space constraints and noise regulations favor mid-size machines. We stock the 20E-54-K1360 for rapid worldwide delivery.

Maintenance & Expected Lifespan
Under standard operating conditions, the 20E-54-K1360 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.
