6754-11-8110 Komatsu Engine Mount — D51EX & D51PX Compact Dozer
OEM-Equivalent • ISO 9001:2015 Certified • Komatsu D51EX-22 • In Stock
Product Overview
The 6754-11-8110 is a rubber engine mount for the Komatsu D51EX and D51PX compact crawler dozers. The D51 is one of Komatsu's most popular utility dozers, used extensively in residential site preparation, landscaping, agricultural drainage, pipeline backfill, and small commercial projects where a full-size dozer would be impractical.
Powered by the Komatsu SAA4D107E-1 Tier 4 Final engine, the D51 produces 130 HP in a compact 13-tonne package. The 6754-11-8110 mount isolates this four-cylinder powerplant from the dozer frame. Like the 20E-54-K1360 for the PC160/PC170 excavator, this mount is specifically tuned for four-cylinder second-order vibrations.
The D51 is frequently rented rather than owned, meaning rental fleet managers need readily available replacement parts to keep machines in revenue service. We stock the 6754-11-8110 for immediate shipment worldwide.

Maintenance & Expected Lifespan
Under standard operating conditions, the 6754-11-8110 has an expected service life of 4,000 to 8,000 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.
