Complete 25-Piece Rebuild Kit for Rexroth A7V & A8V Series Pumps Rebuilding a complex hydraulic pump, especially one with a combined gear section, means you need a lot of small, critical parts. Missing a single gear or drive shaft can stall your whole repair job. To save you from sourcing from three different places, we’ve put together this comprehensive 25-piece kit. It covers a massive range of models, specifically designed for the Rexroth A7V series (from 28 up to 1000), A8V series (55 to 160), and the SR1R. Looking at the breakdown, you get the complete axial piston core: Cylinder Block, Valve Plate, 7 Pistons, Set Plate, Center Pin, and the main Drive Shaft. But that's not all. This kit also includes the gear pump components—two additional drive shafts and two driven gears. We machine every piece from high-grade alloy steel and cast iron with strict tolerances, ensuring a perfect 1:1 fit. Whether it's the piston assembly or the gear set, every part is heat-treated and tested for high pressure and low leakage. For our distributor partners, we offer full OEM/ODM customization. You can easily add your own logo to the metal parts, design custom packaging, and build your own brand reputation in your local market. Don't let missing parts delay your repair. Send us your exact pump nameplate data right now, and we'll confirm the fitment and get you a fast quote.

Rexroth A7V Series Bent-Axis Pumps

I've rebuilt hundreds of these things. The A7V is the bent-axis pump you see on excavators, construction gear, mining rigs - all sorts of heavy machinery. It's not swash plate, it's bent-axis, so the cylinder block tilts at an angle instead of sitting flat. Different geometry, different wear patterns.

When it starts whining, or the pressure drops off, you know it's on its way out. Most shops just rebuild it. New OEM costs a fortune, and there's no guarantee it lasts longer.

We make the rebuild parts. Cylinder block, valve plate, pistons, set plate, drive shafts, center pin, driven gears. Seals and gaskets you can get anywhere cheap - we skip those. The expensive stuff that actually determines pump life, that's what we make.

Huge size range. Small frame 28 to 200 cc/rev. Big frame 225 to 1000. Plus the A8V SR1R series, which is the 55 to 160 size that goes on mid-size excavators and travel drive systems. Covers everything from mid-size excavators up to mining machines.

Every part matches original Rexroth specs. Bores honed. Valve plates lapped. Pistons heat-treated. Checked before shipping.

We stock Rexroth parts across the board - A4VSO, A4VG, A4VTG, A10VSO, A10VO, A11VO, A15VSO, A20VO, A8VO, plus bent-axis stuff like A2F, A2FO, A7VO, A6VM, A2FM.
