Bobcat 331 Excavator
Hi all,

I'm brand new to this site and brand new to owning a min-excavator. I purchased it used knowing it had a few issues. The "bones" are good; no major hits and everything works. But, it has a pretty nasty leak from what the previous owner said was from the "series of 6 hydraulic control valves". He had it rebuilt with new O-rings/seals, but suspects there's a crack in the body somewhere. Now I'm a stranger to excavators, but not to wrenching on things so I'm not afraid to replace or repair stuff. I have plenty of other "toys" that I've built/rebuilt. It drips quite a bit of fluid and I want to fix it pretty quick. I only plan to use it around the "back 40" and not as a business.

On an Inet search, I came across some pics of others repairing the hydro control valve(s) and looks like they came from this site. Technically, I have not yet taken delivery of the machine but plan to pick it up this week. So, I'm looking for some advice on where to get the part, how much (aftermarket is fine), and perhaps a pic or two of what I'm getting in to. I have not unbolted the foorplate to look at it, but can readily see the drips from underneath the cab (under left foot area).

Thanks in advance for any help you can give!
