423-54-25410 Komatsu Engine Mount — WA380 & WA430 Wheel Loader Series
OEM-Equivalent • ISO 9001:2015 Certified • Komatsu WA380-6 • In Stock
Product Overview
The 423-54-25410 is a rubber engine mount designed for Komatsu WA380 and WA430 series wheel loaders. Unlike crawler dozers and excavators, wheel loaders experience a unique vibration profile that combines engine oscillations with the dynamic loads from tire-to-ground impacts during loading, hauling, and stockpiling operations at variable speeds.
The WA380 and WA430 are Komatsu's primary production wheel loaders, widely used in aggregate quarries, ready-mix concrete plants, lumber yards, recycling centers, and port operations. The 423-54-25410 mount isolates the SAA6D107E/SAA6D114E powerplant from the loader frame, preventing engine vibrations from affecting the cab (mounted directly above the engine on wheel loaders) and the ZF transmission assembly.
Wheel loader engine mounts experience different loading patterns than excavator or dozer mounts due to the machine's dynamic operating mode — frequent acceleration, braking, bucket impacts, and uneven terrain. The 423-54-25410 compound is formulated for this mixed-duty vibration spectrum.

Maintenance & Expected Lifespan
Under standard operating conditions, the 423-54-25410 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.
