Wondering if anyone could help on my 3 point. It raises and lowers fully but it takes very little movement to go from fully raised to fully lowered on the lever that
controls position of the rockshaft. I have the draft control lever in the MIN position but it doesn't seem to make any difference where you have the draft control. I
am pretty sure there is an adjustment somewhere but I have no idea the procedure. Any help appreciated.
 

There are several steps outlined in JD 4240 tech manual that describe correct procedure for adjusting L/D control mechanism. I suggest you acquire a JD 4240 tech(TM1181) & follow each step for adjusting 3 pt mechanism.
 
If these adjust the same as a 4020 make sure you weld or tape your socket to the extension you use. I have heard several stories over the years about people having sockets fall off inside the rear end. I have a long extension with the correct socket welded on. Tom
 
Just did my 4040 last week . Rebuilt the 3pt controls , needle valves were bad . Pull the plug under the right side remote . Take a long extension and tape it , 9/16, push in, it's spring loaded and make small increment adjustments. Recommend a 2nd person , one cab and one adjusting. Works great,was doing the same as yours
