Product Description
Hydraulic Main Piston Pump 708-2H-00026 708-2H-00022 708-2H-00450
High-quality replacement hydraulic main piston pump designed for Komatsu PC400-7, PC450-7, PC400-8, and PC450-8 excavators.
Product Specifications
Model: HPV165 Twin Variable Displacement Piston Pump
Part Numbers: 708-2H-00022, 708-2H-00026, 708-2H-00460, 708-2H-31150
Application: Komatsu PC400-7, PC400LC-7, PC450-7, PC450LC-7, PC400-8, PC450-8 Excavator
Common Faults & Solutions
  • Weak movement when hot: Caused by wear of pistons and valve plate reducing volumetric efficiency. Primary trigger is hydraulic oil contamination.
  • Engine lugging & speed drop: Results from misadjustment or stuck spool of PC power valve, EPC solenoid malfunction, or pump displacement issues causing excessive power absorption.
  • Slow movement of whole machine: Typically due to clogged or damaged EPC solenoid valve coil, stuck LS valve spool, or worn internal pump parts leading to insufficient flow.
  • Abnormal noise & vibration: Caused by blocked suction filter, air entering suction pipe (cavitation), damaged pump bearing, or broken piston and shoe.
  • Large case drain flow: Internal pump wear causes high-pressure oil internal leakage, flowing out from pump case drain port.
