pump replacement?

[notme]

hello... i have an old case 1816 uniloader the aux hydraulic pump has a bent shaft... still works but has quite a shake to it. need to find a replacement and not having much luck.

its a borg warner pump
# on the case is S125OAK 55R
under that # is 05098
can anyone give me an idea where i might find replacement parts (shaft) or a replacement pump? its belt driven so a replacement would have to be capable of that. can anyone explain what the stamped in #s might say about this pump?

That was a Case PN: D60567 replaced by D61866 which was used on the Uniloaders including the C Series. You aren't going to find a shaft only and it wouldn't be worth it anyway.


Here is a used one:

Another alternative would be to look up pump model on Google and find one close. Surplus Center shows some, but they are larger.

The product number

The "S12" indicates the pump series, while "50DK5-2r" provides details about its features like displacement, port type, and rotation. You may find this pump for sale from industrial suppliers or on marketplaces, but it is crucial to verify compatibility with your existing hydraulic system before purchasing.

• 50: Likely indicates the pump's displacement (e.g., 50 cc's/revolution)
  DK5: Specifies the port type and design (e.g., "D" for a specific port style, "K" for a seal type, and "5" for a port size).
• 2r: Describes the shaft type (e.g., "2" for a specific shaft end) and rotation (e.g., "r" for right-hand rotation).
