Frequently Asked Questions

Will this seal kit fit my Rexroth LA10VO45DFR1/52L-VRC12K04?
Yes. On the A10VO the seal kit is keyed to the frame size and design, and your code is an NG 45 in the 5X series (52), which is exactly what this kit covers. The control device, 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 R910990934?
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?
Genuine OEM. This is the Bosch Rexroth R902487515 seal kit, new in the factory packaging, backed by our 2-year warranty.

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?
The genuine Bosch Rexroth R902487515 service seal kit for the NG 45 5X pump, as supplied by the factory. It does not include the rotating group, swashplate, bearings or control valve, those are quoted separately.
