125 NF hydraulic pump
 

Has anyone replaced the Shaft Seal (behind the pulley) on a nf hydraulic pump? I have a pump in good working condition but there is a small leak in the seal and I wanted to know if I had to take the whole pump apart to replace it. I've never taken one of these apart and don't know what is involved. I found a seal at ccspecialties for 9.00.
Thanks,
Earl

Hydro repair manual
 

I'm pretty sure there's a service manual in the reference section. I got one for the hydro in my 123 there. Let your fingers do the walking!

I didn't see a service manual, only an installation manual. Thanks

I replaced one a while back. You might get away with just removing the pulley to get to the seal. I can't remember exactly how the seal was in there.

Pump seal # is CR 4911. Most put 2 in because they are thinner then the originals. I have a full right up in PDF format on rebuiling the aux hydro pumps. If you need it let me know. Its a big file.

yeah, I would like the file on rebuilding the pump. You can email it to me at snackpak@roadrunner.com.
Thanks,

I also would like the file. Please email to: seamonster11@hotmail.com. Thank you very much.

It appears I have a leak on my aux hydraulic pump too. Although it's not leaking from the shaft seal, it seems to be coming from around the up/down adjustment arm. Could I have the rebuild file too? pfosen@msn.com

can you email the file to one of the mods so they can upload it to the site in the library section. It would be nice to have available from time to time.

I sent a PM to the gentleman that said he had the repair manual on file, but if anyone else has a copy I'd appreciate if it could be shared.
