Kawasaki K3V Series Hydraulic Pump Parts for Excavators

HYLINK supplies precision-engineered Kawasaki K3V series hydraulic main pump parts and complete rotary group repair kits for heavy-duty construction machinery. Every component is manufactured to original specifications, 100% interchangeable with genuine Kawasaki 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 Kawasaki K3V series is one of the most popular variable displacement axial piston pump platforms widely used in modern hydraulic excavators. Because these machines operate under continuous high pressure and severe load conditions, core internal components—such as the cylinder block, piston shoes, valve plate, and swashplate—are subject to high friction and gradual wear, resulting in symptoms like hydraulic drift, slow movement, excessive operating temperature, or diminished digging force.

HYLINK manufactures complete rotary groups and individual replacement components for K3V45 K3V63, K3V112, K3V140, K3V180, and K3V280 pumps. Engineered from high-strength forged alloy steel and high-leaded wear-resistant bronze, each part is CNC-machined to micron-level precision and validated with CMM inspection equipment. This allows maintenance teams to perform targeted component replacements rather than swapping the whole pump unit, drastically lowering repair costs and reducing machine downtime.

Available Components

Below is the standard component list for Kawasaki K3V series hydraulic main pumps (K3V45 / K3V63 / K3V112 / K3V140 / K3V180 / K3V280). Individual spare parts and complete overhaul 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.
