Bobcat 753, with Hydro Pump Problem

Hi,

I am looking for some advice on a Bobcat 753 that I am considering buying. This loader is a bit of a project. The engine and pump assembly is currently removed. The owner seemed to take care organizing things so he could put it back together. He just got a quote today for $2000 to rebuild all 3 pumps; the loader pump and the 2 drive pumps. The two drive pumps are old, but were working before the loader pump gave up the ghost.

I am new to loaders so if this comes off as a newbie post, that's because it is. Anyways, with that disclaimer, I have done lots of engine work in the past, but I have limited experience with hydraulics.

So this Bobcat has a bad pump; the one that powers the bucket, lift arms, etc. The owner took the pump out, but the engine had to come out to get at it also.

So it needs a new pump, and the valve body is contaminated with pump guts. The guy wants about $2500 for it all torn apart. It has about 5500 hours. The rest of the loader is in good to fair condition.

My question, how bad of a repair is this? I know it is a loaded question, but if I tear down the valve body and get it clean, clean out the lines, etc., what are the chances that this will self destruct again in a short period of time? I don't know how well these machines filter in a bad pump scenario like this?

I figure a new pump, just the auxiliary one, not the two drive pumps could be replace for about $400 or so. Figure in a few buck for oil, etc. and I maybe could have this going for a little over $3000. Does that sound reasonable, or am I dreaming?

Regards,
Tim in Mass
