Bobcat 863f bucket position valve location?

[jmdskid]

Hey guys, kinda going crazy with this one. So my 863 has developed a good hydraulic leak. I followed it back to a "junction block" located on the right side behind the control valve. There's 2 bolts that go through the body of the machine to hold it, next to the 2 bolts that attach the control valve bracket.

After searching and not being able to find anything, I noticed it looks exactly like the bpv valve. The leak is coming from stem for the coil. I assumed the machine didn't have a bucket position valve because there's no switch. But there is an open spot in the panel in the cab. It has the deluxe harness because it has front door w/ wiper and beacon kit.

Before I get all the seals and try and rebuild this thing, can anyone confirm that this is what I'm looking at? I attached a pic of what I'm looking at. Hopefully it helps. Also forgot to add, no serial # of course. I'm pretty sure I know the answer but I wanted to verify. Thank you guys!

I have. That's what led me to think my machine is equipped with the bpv feature and someone just removed the switch in the cab. The bpv valve is the only part I can find that uses a coil other than the 2 main ones on the control valve and 1 on the bics controller. If it makes a difference I noticed those 3 are 10v coils and the coil I removed clearly says 12v.

Basically I just need someone to either verify that it is a bpv. Or at least verify the location on an 863. I'm pretty confident at this point it is a bucket positioning valve. But thanks for your input.

Jmdskid,
I have an 863 F (1999) model.
I can check later today or tomorrow for you.
I am not familiar with that actual part. But I have that feature on my skid steer
Where exactly is it on your machine? IE sitting in the seat for reference?
Let me know.
Todd

If you had the seat flipped up it's on your left side between the control valve and hydrostatic pump. Follow the the harness that connects to the coils on the control valve and follow it back. The last coil the harness goes to is where I'm looking. It's a white junction block with 4 lines going to it and a coil. Between that and the picture hopefully you can see what I'm talking about

Most of the time the problem you have is due to spool seals being worn out. I've attached a video to this message of a guy that shares his Bobcat knowledge with everyone. He's in the business and he knows what he's talking about. He's got a lot of videos on the 763 & 863 machines. This particular one addresses the float function check balls under the cap for the lift spool. If you're going to reseal one spool, do the other while you're in there. You don't want to do that twice.
There's an earlier video that goes from start to finish on that task. Good luck.

Here's a link to the earlier video. Don't forget the safety props.
I put my tractor bucket under the quick attach just for insurance.

Thanks for the reply. I am talking about the bucket positioning valve, not the control valve itself. Hence the picture and description. I've already done the spool valves and seals. Actually followed his video to a T. His YouTube channel is great. But the bucket positioning valve doesn't have spools. It just has a single coil and 4 lines going in/out of it. It looks more like a junction block than anything.

99% sure it's a bpv that's just no longer in use. It's a nightmare. I'd do the spool seals in a heartbeat over messing with this thing. Unfortunately it has nothing to do with the actual control valve. Thank you though.

Sorry, I don't think I've ever run across a 763 with that particular set-up. My personal 763 was a G model. it was a 1999 and always worked well. Just a few leaks here and there, and one pump drive belt when I bought it. That's why I got it so cheap. After the auction was over, they wouldn't let me fix it on site. So I tied the traction lock up out of the way and winched it on to my trailer. But I drove it off the trailer an hour after I got to my shop.

Yes, its same part & mount on my 99' 863F.
See pictures.
