Hi folks- Haven't been here in a while, but sure appreciate all the help I've received in the past. Today, I went out on the farm with my '01 Bobcat 773 to clean up some trees and limbs from a recent storm. I ran into a pretty deep rut in tall grass and had a pretty big bounce but nothing I hadn't done before. Here's the bad part. I ran the machine for about an hour after that. All controls working normally. Got back to the barn, shut it down and immediately saw a trail of hydraulic fluid that followed me in to the barn. Looked underneath and saw a pretty good leak coming from either a new hole or I'm hoping a common drain. Anyway, got the machine up on blocks and then shut it down. The last of the fluid came foaming out. Here's my concern. I can fix the leak, whatever it is, but I'm really concerned that I did permanent damage to the pumps, etc. If anyone can shed some light on my concerns I'd really appreciate any advise. Many thanks, A.Jackson

Did it make any bad noises or start howling badly before you shut it down? If not, I would not be too concerned. Repair the leak, refill it, and see how it goes. I had the same thing happen to me a few weeks back. I left a trail of oil for about 3/4's of a mile while I was driving my machine back home from doing a job in the subdivision up the road. I blew the main pressure hose from the gear pump to the control block. I didn't realize that I was leaking and I was shocked that there was still oil in the reservoir when I got home. Hoping for the best.

probably just rattled something that was about to leak anyway
Put some hydraulic fluid in to the machine today and fluid immediately started a slow drip out of what I THINK is the control valve. This leak spot has a 1-1.5 inch round blank with a rubber cap on it above what looks like a valve housing with maybe two allen wrench fasteners holding the housing. The slow drip is forming around the housing and dripping down. If it is the control valve, can this be removed separately from the giant assembly it is attached to and rebuilt/re sealed? All other hydraulic connections are tight. Would it make sense that this would have been damaged by a big jolt like I had? Any help greatly appreciated.
The valve wouldn't have been damaged by the jolt. It can be worked on in the machine too.
It needs time and new seals, if you are for the job
Thanks Tazzo- I watched a video on you tube that showed fluid streaming out the pin hole in the valve. I'll crank it up today and see if that's it. If so, you say I can just take that piece off and repair without tearing the whole assembly out? I've got a manual also and will look at it. Thanks again
A pin hole in the valve body is different, most commonly it is the seals that run on the spool.
You repair it in place, i have done it on my S150 before, it took some time but wasn't too bad.
