Subject: John Deere 4430 hydraulic pump



Ontario Canada
My uncle has a 4430 with a weak hydraulic pump , today it got to the point where it couldn't operate his round baler anymore. He knew about the problem previously and already got a quote from the dealer to replace it. Quoted $4000 for a new pump plus labour ect from local dealer. I was thinking I could tackle that job for him and do cheaper. A new hydraulic pump from Abilene machine for $1200, I know front axle or radiator has to come out to get at it, maybe new coupler. Is there anything else I should know about to do this job? Or is the dealers quote reasonable and I should let them do it. My day job is a truck mechanic I'm sure I could tackle this though.

Why not rebuild the pump he has? Not that bad of a job just takes a lot of digging to get at it. If you come out the top, slide the radiator out to the side and get someone to help you lift the pump out of the cradle, it saves on the back.

Has someone done tests on the pump? I would make sure that there is not something else wrong before replacing the pump. I have seen a number of times when a pump has been replaced and there was another problem in the tractor and it was not the pump.

Many here will disagree but my vote is for out the top. After the hood is off it is a one man job of 2.5 hours to have it laying on the shop floor. Much safer IMHO.

The job is not that bad, remove the radiator, the core needs cleaning anyway, remove the plate under it you can remove the coupler and the lines. It makes it easier to clean it before you remove lines and other items. I&T manuals are your friend, Actually are easier to understand than the jd manual, i have both. I overhauled the original pump once, and got a used pump the second time. Also put in the high capacity charge pump in the rear end, that made a big difference for an aging tractor.

We rebuilt the one in our 4230. @$600, if I remember right. I see A&I sells many parts for them, including the shaft. Maybe others do too.

Abilene is the Last place I would order a pump from. It took me 4 tries to get one that worked.

Have you checked the stroke control? I would do that before pulling pump. Then maybe up pressure on pump.

Plus, check the filters, suction screen on bottom of tranny and charge pump pressure.  Possibly priority valve???

All good suggestions thanks, at this point I'm gonna see what my uncle wants to to we may end up making sure the pump is toast before anything, then go from there. At least we have options now.
