I'm not sure what the IT manual says but I'm thinking that you need a tool to turn the adjustment inside the trans case. I have welded a 9/16 socket I think it is on a rod or just used a long exstension and taped the socket on so that it will not fall into trans case. Try moving the load and depth lever that is by you feet towards the back or side depending on the model year and see if that doesnt make it raise.
Hope that helps
any more questions please ask

Your answer does not address the problem. The hinges which control the valves require the JD tool and are setup with a dial indicator. A clearance of .007 is the correct clearance to get the hyds to work. Without the tool I don't see any way to set the clearance. The IH manual says it is impossible to set up without the JD jig.
The control you reference sets the height of the arms after it is operational.
I was hoping some ingenius old timer had a way of setting the clearance.
Thks anyway for the response but I can't accept your response. Tom
