Thanks for the reply man. Well, I have a Service manual for the machine, but it only tells you how to take out the pump. It also gives you a part number for a new pump. Thats great, but a rebult one is like $700 plus shipping.
Tractor companies usually print the pump manuals separate. I don't remember how Case did it. I have the separate manuals printed by Deere and IH.
Send me a private email and I'll send you a link to download the complete Stanadyne/Roosamaster DB pump manual (you've got a DB pump). Manual is over 200 MB in size, so hopefully you're not on dial-up Net access. I'm on satellite-uplink here.
There are several places that sell the parts to anybody. A complete seal and small parts kit is around $15.
$700 doesn't get you a truly rebuilt pump. It will get you a pump that's been cleaned up, calbrated, and most major parts used as-is, with no renewal process. Basically $25-$50 new parts put in, that's all.
When I worked in a pump shop in the 1970s-1990s, all our parts came from Stanadyen or John Deere. Now, they are available aftermarket and much cheaper.
The following place gives me great service and sells to anyone. They will also let you download their catalog. Prices are from last year and have probably gone up a bit. You will at least need the seal kig and the brass bushing I listed.
