Short Description
Premium factory-direct aftermarket Kawasaki K3V Series Axial Piston Pump Spare Parts and Overhaul Rebuild Kits, precision-engineered as 100% seamless drop-in replacements to restore original volumetric efficiency and hydraulic breakout forces. Covering standard global frame configurations including K3V63DT, K3V112DT, K3V140DT, and K3V180DT, our massive wholesale inventory features heavy-duty bimetal cylinder blocks and induction-hardened piston groups designed to eliminate internal pressure tracking and comfortably survive continuous severe earthmoving cycles up to 350 bar.
Key Highlights
-
100% Interchangeable OEM Blueprint Tolerances: Completely reverse-engineered to precise Kawasaki original factory heavy-machinery micro-clearances. Internal rotary groups fit seamlessly into original pump housings with zero component binding or dynamic shaft alignment issues.
-
Upgraded Lead-Bronze Fusion Cylinder Blocks: Our K3V cylinder barrels utilize premium high-density bimetal cladding technology. The copper friction interface is fused under extreme thermal calibration to drastically extend boundary lubrication and prevent dynamic face scoring under hot oil shocks.
-
Induction-Hardened Pistons & Micro-Lapped Shoes: Piston bodies are forged from premium structural alloy steel and treated to an ideal surface hardness of 60-62 HRC. Shoe slipper faces are micro-lapped to absolute optical flatness, mitigating the high risk of shoe-off-plate structural failure during aggressive excavator crushing loops.
-
Massive One-Stop Inventory Readiness: Ready-to-ship wholesale stock for all high-wear internal items including Cylinder Blocks, Piston Groups, Valve Plates (Front/Rear), Set Plates (Retainer), Ball Guides, Drive Shafts (Splined), Swash Plate Assemblies (Cradle), Support Rollers, Pilot Charge Pumps, and complete high-temperature FKM (Viton) Seal Kits.

FAQ
Q1: Kawasaki K3V112DT pumps use distinct Front (F) and Rear (R) Valve Plates. Do your rebuild kits include both correct porting layouts? A: Yes, absolutely. In tandem K3V dual-pump designs, the Front Pump Valve Plate and Rear Pump Valve Plate feature mirrored mirroring fluid channels to accommodate proper cross-over porting. When placing your wholesale batch or workshop rebuild order, our technicians will cross-reference your specific application to provide the exact matching paired front and rear valve components.
Q2: Excavators working with hydraulic breakers face extreme shock waves. How do your K3V parts prevent premature cracking? A: Operating a heavy hydraulic concrete breaker creates intense pressure spikes that hammer the pump internals. To prevent premature fatigue, our K3V components are processed using advanced isothermal salt-bath quenching. This delivers excellent impact toughness, enabling our cylinder faces and ball guides to handle aggressive hydraulic shockwaves without micro-cracking or slipper detachment.
