HYD PUMP

(quoted from post at 09:23:35 08/29/14) I have a Ford 8N with a wagoner loader. The hyd pump
driven off the front of the engine is leaking oil
badly. Is it possible to obtain a kit or seals to
repair this. What usually goes bad on them.
Thank you

If you look hard enough you can rebuild them. My pumps are bother Vickers.

I researched all over the web and got a number from the folks who now deal with vickers. (Eaton Corp I believe). Got a hold of an old timer who was more than willing to help. He remembered those old pumps and therefore emailed me a good bit of info.

I downloaded all other parts manuals and schematics and break out charts that I could find. I rebuilt 2 Vickers vain pumps. Replaced the vains bearings, o-rings, seals and used Timken bearings. I had to true up the surfaces on the pump housings and rotor housings not to mention the internal cutout in the rotor housing where the vains ride against. I tued up the metal surfaces using a belt sander mounted upside down in a vice. Used a heavy grit belt to take off metal (as minimal as possible) and moved up to a 300-400 grit to smooth everything out.

I rebuilt the original pump that I had on my dearborn loader and another that I purchased off of ebay for $70 that was slightly larger than the one I had.

I rebuilt them just so that I can say I did and learn from it.
But....as TOH said and he is a wealth of info in this area, replacing the entire pump with a new style gear driven variety is the best way to go. Both economically, emotionally.
