Frequently Asked Questions

Will this seal kit fit my Rexroth LA10VO71DFR1/31L-VSC92K04?
Yes. On the A10VO and A10VSO the seal kit is keyed to the frame size, and your code is an NG 71. 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 R910974838?
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.

Which seal material do I need?
Position 08 of your type code is V, so this pump left the factory with FKM (Viton) seals and this kit matches it. FKM suits petroleum oil, HFD fluids and higher operating temperatures. If your machine runs HFA, HFB or HFC water glycol fluid, email us and we will quote the NBR alternative.

What is in the kit?
A complete seal kit for the NG 71 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.
