Rexroth A10VSO Hydraulic Pump Repair Parts

This high-precision plunger hydraulic pump core overhaul and repair spare part is specially designed for Rexroth's classic industrial and engineering machinery A10VSO series variable plunger pump. The product fully covers and accurately applies the full range of A10VSO16, 18, 28, 45, 63, 71, 85, 100, and 140 displacement pump numbers, with perfect platform level modular interchangeability between each specification. This high-end original factory level overhaul component (including cylinder body, plunger, distribution plate, nine hole plate, inclined plate and other core rotating friction pairs) is a pure and high-quality spare part in the aftermarket, widely matched and fully restored to the absolute power of engineering machinery hydraulic systems and industrial hydraulic stations. The product is finely ground based on first principles. Taking A10VSO45 as an example, the physical dimensions of the product packaging are about 320mm × 210mm × 190mm, and the overall net weight is about 11.5kg (each displacement specification is adjusted according to the size).

"Dust free assembly and torque fastening (core pit avoidance): The assembly environment for major repairs must meet dust-free purification standards. All friction pair surfaces must be coated with clean hydraulic oil as initial lubrication during assembly. All high-strength fastening bolts must be tightened using precision torque wrenches, strictly following the original factory torque standards for symmetrical and phased cross tightening, to prevent micro stress deformation from causing jamming.

Forced oil filling and turning: After the overall combination of the main pump is completed and the pipeline is connected in place, clean new hydraulic oil must be filled from the top of the main pump's oil injection port/housing drain port before starting the engine or motor for the first time, and manual turning must be done several times. It is strictly prohibited to start dry grinding, otherwise the internal rotating components will undergo irreversible physical erosion within 3 seconds of ignition."
