wd45 hydraulic pump adjustment for sale

I"m thinking about tearing into the pump to see why my remote outlet pressure is only around 1500psi instead of the 3500psi. Whats the best manual one can get?? I have seen the I&T and I would like something very detailed like a dealers manual. Also, does anyone else on this site have any of the many pump parts or will I just have to take it in the rear from agco??? Thanks in advance, Ryan

If you can get ahold of some sort of manual for it I"d be interested in a scan or a copy. The pump on my 45 needs some love as well. It doesnt seem to work with the traction booster at all. When I try to set it it creeps up or down wont maintain a set height.

I bought all the stuff from Sandylake but in reality it probably just needs a good cleaning out. The slightest bit of FOD in there can mess things up. Same pump on the CA and there is no screen and to make matters worse it pulls from where the metal is. They have a rebuild kit with gaskets, balls, springs and the such.

If you decide to re-build it, I have gaskets, small parts kit, I bought years ago from SLI to do one, don"t think I will need the stuff. Also, have a couple used pumps I need to find homes for.

I did the pump on My CA last year. It had a couple broken springs in it . Agco dealer had them in stock I think I spent $20 on springs . I did wind up taking it apart 4 times befor it worked correctly. It only takes a very small piece of FOD to keep it from working correctly. so after you think you have it clean clean it again . There is really very little to go wrong inside the pump. I also made the pump gasket out of cerial box after I ripped the one I bought on the third disasembly.

When my Dad and I rebuilt his WD back in "58 (I was 17 at the time), he gave me the task of rebuilding the hydraulic pump. Keep in mind the tractor had been thru a barn fire and then left to stand outside for a few years.

I hope you have better luck than I did.Back in the day,my dad was the neighborhood mechanic and had worked on plenty of AC pumps but never could "fix" mine.

Sounds like maybe the body of your pump was defective or developed some internal problem not easily detected. Could have/can try another pump? There seems to be plenty used on the market, small parts are not to costly, worth a try.

Chris,I put all the guts in another body with the same result.I even put the good working pump off the WD on and it was better but not as good as when on the WD.Pump lobes look excellent.No play in brgs etc.You tell me what"s wrong. I"m the guy who has the "unusual" things happen.It"s apparently my lot in life.

Thanks for posting, Ted. I can print these out from originals a nd mail them to anyone if they are something you would like. These are from my "Old" AC service binder, actually has pictures of B/C pumps showing oil flow in "red" ink, alway"s thought that color ink was unusual for older manuals.

Maybe I am over thinking this. I just need a very good service manual. I"m not talking a manual from a farm store. I want to get one that dealer mechanics would use. I really want to understand this pump. Ryan

I"m not sure a dealer service manual is going to be all that more informative than what is currently available. In the years those tractors/pumps were made, the service manual was adequate for most AC mechanic"s to understand and service this part. They are not that complicated, no rocket science degree needed. maybe call MACK and pick his brain some, he might have some more technical lit to send you.

Can anyone tell me how to somehow convert the single hydraulic to a functioning 2 hose hookup...is there a bypass/throw valve that will allow this to work or....how much of a trouble is it to get this to work..t.i.a.
