Overview
HYLINK supplies precision-engineered Uchida Rexroth A10VD series (A10VD17, A10VD23, A10VD28, A10VD40, A10VD43, A10VD71) swashplate-design axial piston variable displacement dual pump replacement parts and complete rotary group overhaul kits. Specially designed for mini excavators and compact construction machinery dual-circuit main hydraulic drives, every part is manufactured to exact original tolerances and thoroughly inspected before shipment. This provides a high-performance, cost-effective replacement solution for repair shops, hydraulic distributors, and equipment maintenance teams worldwide.
Product Overview
The Uchida Rexroth A10VD series variable displacement dual axial piston pumps serve as the main hydraulic power source in mini excavators and compact construction equipment. Operating under continuous multi-function duty cycles and high mechanical shock loads, internal rotating assemblies—including drive shafts, twin cylinder blocks, pistons with slipper shoes, swashplates, ball guides, valve plates, and spring assemblies—undergo continuous friction over extended operation. Mechanical wear on these critical contact surfaces leads to output flow degradation, increased internal fluid bypass, temperature buildup, and loss of hydraulic driving power.
HYLINK manufactures high-precision complete replacement rotary groups and individual spare parts across the entire A10VD frame size range from 17 to 71 cm³/rev. Produced from premium forged alloy steel and high-wear-resistant bronze compositions, each component undergoes micron-level CNC machining and CMM quality inspection. This enables service technicians and equipment rebuilders to restore original hydraulic dual-pump efficiency and performance without purchasing expensive complete pump casings.

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.
