8n 3pt Issue

[ashersp]

Hello all,

After scouring the internet and forums, I can't find anyone with the same issue as I have.

I have a 1952 8n w/ the Sherman auxiliary trans. I bought the tractor as a basket case with the 3pt assembly and hydraulic pump disassembled and left in the elements for an extended period of time. The proof meter is inoperable but shows 2,902 hours before it stopped working.

I rebuilt the hydraulic pump and replaced the piston, cylinder and cam follower on the top lid. I also set the two springs to the correct length.

My issue is that when in both draft and position control the touch control lever raises the implement at the top of its travel and will hold it but as the touch control level is lowered the implement will drop and not maintain position. I suspect this is similar to how it would operate in draft control?

I have verified there is no leakage at the cylinder by opening the side cover. The 3pt will hold a heavy brush cutter for an extended time with the tractor shut off as well. So long as the touch control is left at the top of its travel.

There was a lot of wear/slop in the linkages inside the top cover, I assume this is where the problem lies but I would much appreciate what component(s) in particular would cause this issue or what specific adjustments I need to make.

I greatly appreciate any feedback.

Thanks,
Asher

There is a Ford 8n forum. Might want to post down there.

Thank you for the reply Mark. I also have a post there, fingers crossed I get some pointers before I just tear the top lid apart and start replacing components.

Thanks,
Asher

There was a special tool for initial setup of the cover and linkages, referred to later as a Zang thing?? Remember taking one downtown and having the dealer set it up for me.

Thank you for the reply sir. Could you please send me a link to the forum? I found a few Ford N series forums and likely overlooked this one.

Thanks,
