Komatsu HPV75 HPV95 HPV132 HPV140 HPV165 Hydraulic Pump Parts

HYLINK supplies precision-engineered Komatsu HPV series hydraulic main pump parts and complete rotary group repair kits for heavy-duty excavators. Every component is manufactured to original specifications, 100% interchangeable with genuine Komatsu parts, and fully tested before shipment — providing a reliable, cost-effective replacement solution for repair shops, distributors, and fleet maintenance teams worldwide.

Key Specifications

Product Overview

The Komatsu HPV series (including HPV75, HPV95, HPV132, HPV140, and HPV165) is the core hydraulic main pump system powering Komatsu’s flagship PC series excavators. Designed for continuous high-pressure operations, key rotary components—such as the cylinder block, piston shoes, valve plate, and swashplate—endure severe mechanical stress over time. Wear in these components typically leads to performance issues such as hydraulic drift, reduced cycle speed, overheating, or loss of breakout force.

HYLINK manufactures high-precision complete rotary groups and individual replacement components for the entire Komatsu HPV pump range. Crafted from high-strength forged alloy steel and wear-resistant bronze alloys, every part undergoes precision CNC machining and CMM micron-level verification. This allows repair technicians to replace specific worn components instead of buying a whole new pump, significantly lowering repair costs and minimizing machine downtime.

Available Components

Below is the standard component list for Komatsu HPV series hydraulic main pumps (HPV75 / HPV95 / HPV132 / HPV140 / HPV165). Individual spare parts and complete overhaul repair kits are both available:

Quality Assurance & Manufacturing

Every HYLINK pump and replacement part undergoes strict quality control before shipment:

l Dimensional accuracy — checked with high-precision CMM (Coordinate Measuring Machines) to guarantee an exact fit with original pump housings.

l Material metallurgy — manufactured from premium forged steel and high-wear-resistant alloys to prevent premature fatigue.

l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.

Packing, Shipping & Warranty

l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).

l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.

l Warranty — 6 months quality assurance against manufacturing and material defects from the delivery date. In the event of a confirmed quality defect, HYLINK provides hassle-free replacement.
