Got my 850 Resto running this week. Big Smiles. BUT. After getting rebuilt pump primed and working smoothly, my hydraulic lift works only in Implement Position, and not at all in Constant Draft Control Position. IT and Shop manual have same explanation on how to fix. It refers to Nuday Tool NCA-502 to set correct gap between control valve land and valve housing. From the photo it looks like a simple thick go-no-go block. To make my adjustment to the turnbuckle I don't need the tool, but I do need the dimensions or thickness of this block. Does anyone have one, and can you let me know the dimensions? Also, any tips to making this adjustment as I do not want to remove the lift cover. Thanks to all as usual, Larry

For some reason my follow up comment did not show up. I thought I could do it without removing the cover because the Manual says to remove the inspection plate (the one with the dip stick) and measure the gap that way, so I assumed I could make any adjustment through the inspection plate hole. Obviously, you guys have more experience than I in this area, and I am resolved to remove the lift cover. That makes it a Winter project once I get enough Kero for the tank to heat my garage, get the gasket and O rings, put the come-along up to the rafter, etc. Of course, here in Maine, Nov. is deer hunting season, so I'm afraid I have to prioritize finding bambi over fixing the 850. Thanks all, I will first try to adjust the draft plunger.

Try backing off the draft plunger a few turns...


The draw back is it changes the height of the lift arms when in the lower position...

If you manage to adjust it without removing the cover then you are definitely the king of Ford tractor repair! Never known anyone to be able to do that, but the good news is the cover comes off easily just be sure and have the gasket and two o rings especially on hand

The I&T manual has instructions on the dimensions to measure without those special tools.
It says to remove the lift cover. Never heard anyone do it any other way.
