Product Detail

Hydraulic Pump Assy – Part No. 705-95-07121 for Komatsu HD-785 Dump Truck

This hydraulic pump assembly is a genuine replacement component specifically designed for the Komatsu HD-785 dump truck. It is a primary hydraulic power source, typically driving the dump body hoist circuit, brake charging system, and auxiliary hydraulic functions. The pump is a high-pressure piston or gear type (depending on application), featuring precision-machined internal components, heavy-duty bearings, and high-temperature seals to withstand the extreme demands of mining and heavy construction environments. The 705-95-07121 assembly includes the pump housing, rotating group, pressure regulator, and mounting flange, all factory-assembled to Komatsu’s exact specifications. Proper function of this hydraulic pump is critical for reliable hoist operation, brake performance, and overall machine productivity. Using an authentic Komatsu pump ensures correct flow, pressure rating, and long service life. Regular inspection for noise, leakage, or pressure drop is recommended, and replacement should be made with genuine Komatsu parts to avoid system failure.
