Ford 3000 Flow Control Valve
Got the valve back yesterday from the machinist who trued it up. It looks great, but I still had a slight weep from the bolt hole. Thinking there might be a very small opening from the crack that we didn't get filled. I'm going to pull it and fill that bind hole with epoxy or permatex (eek!)... -

The saga continues... The auxiliary valve had one of the bolt hole "ears" broken off of it when I got it and the crack goes through the large o-ring (blind hole) on the valve. I couldn't get the o-ring to seal it, so I decided to go with a gasket for the whole valve. I just couldn't get it... -

Success! I ended up splitting the pump in half and wiping everything down and cleaning it up good. I made a couple new gaskets and assembled it and verified it worked by pouring oil in the suction side and cranking the gear to see it suck it in and push it out the pressure side. Some old... -

Took the pump off of the tractor this morning. I blew through the suction line without any trouble, so I poured a little hydraulic oil in the intake of the pump and manually turned the gear drive. The oil was never sucked into or out of the pump no matter what direction I turned the gear... -

3/30/12 update: I haven't had any time lately to dig into the problem any further, but I thought I'd take the tractor over to my inlaws and use a larger compressor (that works!) to try to pressurize the oil reservoir. I left the tractor running at approximately 1800 rpms. I removed the... -

Tried to pressurize the reservoir tonight. My little compressor was acting up and would only pump 35lbs, but that should have been enough, right? Ended up pressurizing through the oil level check plug on the side of the tractor behind the flow control valve. Tractor was running when... -

I managed to get the line brazed back together again. Not a professional job, but should work. I didn't get a chance to try pressurizing the reservoir last night, so I'll try to make it happen tonight. Yes, the tractor is a mid-70's model, so it has the press-in suction tube. I will try... -

I'll give it a shot. Might go ahead and replace the seals on the suction line (at least the ones on the outside of the tractor) just in case. That would be cheaper than a pump overhaul! I will report back as soon as I can and let you know the outcome. -

Got some orings replaced and put the tractor back together again but still no lift. Went to make sure the system was primed and realized that I've got no pressure coming out of the prime plug on the pump. This mean the pump is shot? Going to see if I can find an overhaul kit for it if so. -

Ok, I got it. For future reference, there is a small c-clip located near the bottom of the pipe that keeps it from dropping down. Just removed the clip and lowered it down to get clearance to pull the the valve, then pulled out the pipe. Turns out that the o-rings are shot on this pipe, which... -

Ok, I'll try that with the pipe and see if it works. As far as the pipe with the hole, this isn't on the pump suction line, it's actually on the return line with the back pressure valve and return filter. Going to see if I can get it brazed anyway, but shouldn't be the culprit. I managed...
