I posted on here about my TO20 3 point quit, It was working, and I went to use the rear blade and it wouldnt come up, I have had it apart 3 times now, the last time I installed a new by pass valve and a new control valve . The bypass valve was missing a valve and a spring, figured that was the trouble, I took the pump all apart and it was clean, and looked great, springs all were the same tension , put it together and nothing, I guess I am done with it, I got this tractor in 1966, I had some advice on here and tried every one, but nothing, I am to old to keep crawling under the tractor,

Your original post has now migrated to page two.
Have YOU inspected this item?



A possible solution from the other board and Hobo(NC)
There is a long spring on the lift linkage that attaches from the linkage to the lift cylinder I have seen them break is it intact... JMOR has a pix of it... If its broke the lift will not work : (

Unless you have already really, really given up on it. if you were closer than Michigan, I might take a road trip and make an offer.

As I stated previously, posting your hyd problems over on the 9N/2N/8N Ford board might yield better results.
Last time I even provided a link to that forum on this board. No oil going up is either a busted pump, I think not, a stuck valve not building pressure or stuck open and bleeding off.
Your about 2500 miles too far away from me. I know that many Ford machines use the same pump and trying to fix an old one with china almost parts sometimes does not work. I put together a Fergy pump with China parts. Now it thumps under a load.
It will get replaced with a Ford pump.

I had the pump all apart, the pistons and cylinders are in great shape, the valves beside the pump are in good shape, the springs are all the same tension. The tubes going up to the piston and cylinder are open, and I did post on the Ford N site, Thanks for helping

Then you have also had the side covers off while in operation to observe oil flow and potential leakage from the top cylinder?

Could be a hole in the pipe going up to the cylinder as well. Bright light and a telescoping mirror may help see where it's leaking.

Have you inspected the lift cylinder and piston? You said you started using this tractor in 1966. That is a lot of use on that assembly.

I checked the pipe, and the cylinder and piston , I put air to the piston, it jumps, I blocked the pipe off at the bottom and put oil in it and then air, no leaks. no oil comes up the pipe. There isnt a part that wasnt taken apart in the pump

There is no oil flow going to the pipe, its all clean and not plugged, I can see the pump working, The tractor is 73 yrs old, but the pump and all its parts were tight, I did replace the bypass valve and control valve

73 years old? H*ll that is getting to prime time. You had the cover off and the machine running to have a lookee-loo?
If that pump is all that then either you have a bad connection or as stated, a bad pipe. Pull both side covers and run the silly thing.
Question is, is that machine older than you or younger?
Most my machines, tractor machines, around here are a bit older than me. There is one though that has a whopping 22.3 hours on it.

I had the same trouble with my TO 30 a small pin came out of the wishbone which caused the valve not to open fully the control valve would move but not far enough to operate the lift
