Frequently Asked Questions

Will this seal kit fit my Rexroth A10VO140DR/31L-PSD12K17?
Yes. On the A10VO and A10VSO the seal kit is keyed to the frame size, and your code is an NG 140. The control device, series index, rotation, shaft, mounting flange, port position and through drive do not change which kit you need. Send the full code from your nameplate to info@restopower.com and we will confirm fitment the same business day.

What is R910998310?
That is the Bosch Rexroth material number for this exact build, the R number printed on the pump nameplate sticker next to the type code. If the sticker is gone, the type code stamped into the housing is enough for us to identify the kit.

Is this genuine OEM or aftermarket?
New OEM Equivalent aftermarket, manufactured to meet or exceed the original Bosch Rexroth specification and backed by our 2-year warranty. We also source genuine new OEM parts when a job calls for it, just ask.

Should I take Viton or Buna-N?
Position 08 of your type code says the factory built this pump with NBR (Buna-N) seals. Both materials are offered above and both fit the NG 140 31 design identically, only the elastomer differs. Viton is on the shelf and is the better choice for petroleum oil, HFD fluids and higher operating temperatures. Buna-N is the correct choice for HFA, HFB and HFC water glycol, where Viton is not suitable, and we quote it rather than stock it, so pick that option and we will come back with price and lead time. If you are unsure, send us your fluid type and we will pick.

What is in the kit?
A complete seal kit for the NG 140 A10 pump, shaft seal, all housing and cover O-rings, control and port seals and back-up rings. It does not include the rotating group, swashplate, bearings or control valve, those are quoted separately and we stock them.
