Caseih885 3ph adjustment

philcase · Jun 13, 2016

When the 3ph arms are up as far as they move there's still about
5 inches of lift I can raise them by hand. If I bump the remote
valve they will raise another 2 or so inches. I know there is
some free up movement of the arms but I think 5 inches is a lot,
or am I wrong? I could use a little more lift. Is there an
adjustment on the arms. When they are all the way down they are
lower than anything I need them for. One person said he had
shorten the Lift links to get more height.

Hi Phil, there is a 3pt lift height adjustment in the I&T service manual but its is not very clear adjustment.
My Dad/Brother's 684 had the same problem with a JD 3pt corn harvester. I believe the problem was a design problem. To give the larger 74/84 series tractors a greater 3pt lift capacity for heavy cat II equipment, the engineers connected the 3pt lift links out closer to the load points but with the larger wheel diameters on the larger 74/84 tractors they had to lengthen the lift links otherwise the 3pt would not lower enough for some in ground implements.
Here is what we did, we took the lift links apart and there is a big hex nut that screws onto the upper lift link shaft. We screwed the nut further up the shaft but you have to be careful that the shaft end protruding the nut does not bind on the 3pt lift arm when it is lowered to the max. We actually cut about 3/4 inch off the bottom of the threaded part below the nut of the upper lift links to make the 3pt lift higher and also lower to the max without binding.

See caseih parts link. item 1 is the nut, thread on item 8 and 22.

Hope this helps

If you pull BOTH the position control and draft lever all the way back you will gain the missing inches. Annoying since you now have to use both levers to raise and lower...
