You can buy Rexroth hydraulic pump parts and seal kits from RestoPower, an independent hydraulic parts supplier and rebuild shop in Lake Orion, Michigan, with over 4,500 Bosch Rexroth parts and seal kits listed, most of them for the A10VSO, A10VO, A11VO and A7VO families, and seal kits on the shelf for the common A10 frames. For obsolete or superseded Rexroth numbers, send us the type code and material number off the nameplate and we reply with price, availability and lead time.
The short answer: A10VSO and A10VO seal kits and listed parts are on our site now. Everything else, including A4VG, retired numbers and units nobody lists anymore, starts with the nameplate. Send it to us and we will tell you straight whether we can get it.
What Rexroth parts does RestoPower carry?
Our deepest Rexroth coverage is the A10 open-circuit pump, with every frame from 10 through 140 broken out into its own parts catalog. The table below is what the catalog holds today. "On the shelf" means priced and ready to ship. "Listed, quoted" means the part is cataloged with its Rexroth number and we price it when you ask. "Sourced to order" means we do not list it yet, but we go and find it.

Not sure which kit is yours? The A10VSO and A10VO model code decoder lists the Rexroth kit number for every frame, design and seal material.
Can you get obsolete or discontinued Rexroth parts?
Often, yes. A pump that has run for twenty years on a press or a test stand usually outlives its catalog listing. A few things we see over and over:
- The design generation matters more than the frame size. A 31 design part and a 52 design part for the same frame are different parts, and Rexroth publishes separate seal kits for them. Order by frame size alone and there is a fair chance you get the wrong kit.
- Old numbers carry over. Many older A10 component numbers carry a BH prefix that maps onto today's R91 numbers. We cross them, so an old parts list is still useful.
- The seal letter is in the code. In the A10 type code, P is Buna-N (NBR) and V is Viton (FKM). If the pump is running hot or on a fire-resistant fluid, check which one you actually have before you order.
- Sometimes the answer is a rebuild, not a part. When a component is gone for good, rebuilding what you have, or matching it by dimension and function, can be the only practical route. We tell you which way we think it should go and why.
If we cannot get it, we say so. A fast no beats a promise that sits on a desk for three weeks.
Is RestoPower a Rexroth distributor, and are the parts genuine or aftermarket?
RestoPower is an independent supplier, not a Bosch Rexroth distributor or factory outlet. Most of what we sell for Rexroth pumps is new aftermarket, OEM-equivalent parts made to the Rexroth part number, and every listing shows the Rexroth number it replaces. When a genuine factory part is what your application or your customer requires, ask for it: we quote genuine where it is available and we always tell you which one you are buying. Being independent is also why we can still chase parts for pumps that dropped out of the factory catalog years ago.
Why buy Rexroth parts from an independent supplier?
| What you need | What we do |
|---|---|
| An A10 seal kit for a running machine | Matched by frame, design and seal material from the nameplate code. In-stock parts ship within 24-72 hours. |
| A part that is no longer cataloged | Traced from the type code and material number, crossed from older BH numbers where they apply, then quoted with price, availability and lead time. |
| A pump that is past saving with parts alone | A rebuild through our A10VO and A10VSO rebuild service, or a seal kit if you are doing the work yourself. |
| A worn-out core sitting on the shelf | Credit toward your next order through our core buyback program. |
What do I need to send to get the right Rexroth part?
The nameplate. A Rexroth pump carries a type code (A10VSO18DFR/31R-PPA12N00, for example) and a material number starting with R9. Between them they give the frame size, design, control, rotation, shaft, ports and seal material, which is everything needed to order internal parts. Send a photo of the plate if you can. If the plate is gone or unreadable, send photos of the pump, the shaft, the mounting flange and the control, and we work from those. These guides help you get there first:
- Rexroth A10VSO and A10VO model code decoder, block by block, with the seal kit for each frame.
- Bosch Rexroth pump guide: A10VSO, A4VG and A11VO explained.
- How to identify a pump with no tag.
- A10VSO and A10VO pump troubleshooting, so you buy the part that actually fixes the problem.
- A10VSO pressure compensator adjustment.
Can you rebuild my Rexroth pump instead?
Yes. If the rotating group is scored or the case drain flow says the pump is worn out, parts alone may not save it. Repairs happen in our shop in Lake Orion, Michigan, or through the RestoPower repair network, and we arrange getting the unit to the shop doing the work. The teardown evaluation is free, you get a firm, itemized quote before any billable work, and work done in our shop carries a 1-year repair warranty. For a network job, the price, turnaround and warranty are confirmed on your quote before work starts. See the Rexroth A10VO and A10VSO rebuild service for what the job covers.

What information do you need to quote a Rexroth part?
The type code and the R9 material number from the nameplate, plus a photo of the plate if you can. If the plate is gone, send photos of the pump, shaft, flange and control. For A10 pumps the frame size and design generation decide which parts fit, so both matter.
