Looks like the arm has been whacked on the upper corner inside part of right lift arm. Wonder if spline orientation is the same from the left side to the right side...?

You can remove fender and use a large puller like above to remove arm. This style puller can be set up as a 2 or 3 jaw. Clean up internal and external splines good with a wire brush and reassemble with anti-seize compound.
I agree with steve(ill). Looks like 16 spline shaft = 22.5 degrees per spline. If you move the arm one spline and the arm is 15" -16" long, the end of the arm would move 5-6". Way too much to fix your issue. So something has to be bent or twisted. I would crank on the lift adjustments to dial it in and avoid disassembly and opening a bag of snakes.

To KEEP IT SIMPLE S how about removing the left hand crank and adding a stack of flat washers ( an inch plus ) to raise the Crank and be a closer match to the right hand crank.

Why not just pull housing off and check shafts. Then u can also replace cylinder packing and hyd. hose while in there . Then u can press the shaft out of the arm with out damage to arm.

If you have plans of using the 3 point for anything the housing needs to come off to see what needs to be repaired. It’s not that difficult of a job. Continuing to use it with a bush hog or other heavy equipment could result in further damage. Get a service manual and you can see how it comes apart.

location is part of the problem......
The tractor is 4 hrs away on my farm and it will be a couple of weekends till I get there to work with it. I've only recently acquired the tractor so not sure what happened previously to create this situation.
At the end of the day, this is a hobby tractor for a hobby farm. Plan was to utilize this tractor for brush hogging and misc chores. |

Is there someone at or near you farm that could try and lift up the RT arm? Other than the RT shaft having been twisted as a lot have suggested; and although not likely, if there's a great deal of free movement, it may have even sheared.
Revisiting the 1-spline index; this would be too much of a distance on the end of a 15" arm when moved one spline, compared to the picture.

When I twisted dad’s left shaft it didn’t break in 2, it twisted and dropped the left side. No damage was done to the rear housing. When I heard it thankfully I dropped the plow immediately. It was too late but it may have prevented further damage.

I tried counting the splines on my D-14, SC arms...15 or 16 ( fender is IN the way,kept losing count.....). Tried Google, a few pictures,but no GREAT shot of the end. Still either 15 or 16 won't make a big difference to Gatz' drawing and numbers. Sure hate to think of the force that did twist the shaft though !!!
Honestly, I'd put the tractor on a trailer and bring her home to SAFELY work on it. There is NO way I'd TRY to remove the rockshaft off without some kind of crane. Did mine, in my garaeg with overhead Ibeam, chain hoists,lotsa light, tools and it was 'ok',AFTER I dumped the diff oil into a 5G bucket....yeah that SHOULD have been 'step 1'..... While it's home,reseal the ram and add a swivelled hose while it's apart !

Thank you everyone for the help! You all have helped me realize that 1) I have an issue that most likely is a twisted shaft and that 2) I need to take the time and consideration that this won't be an easy job where the tractor sits 4 hrs from here. Without my shop built yet, my plan is to trailer the tractor down to my Dallas residence and properly delve into getting this resolved.
As others have mentioned, I can probably "live" with this for awhile so it may be Summer till I get it down (wrapping up a Land Cruiser restoration so my extra garage space is currently utilized). With that said, I did just purchase another D15 II that will be ready to "hit the ground running" so that helps buy some time as well. I did have to explain to the wife that I "needed" another D15 II though in the meantime.  |

A good choice, it’s a really good tractor for its size. Does well with a bush hog on it

Hell, My theory is is that you need another AC tractor, for every attachment you own. That way you won't injure yourself transferring 3 point equipment, from 1 machine, to the ground, to another. Note, this does not apply to snap coupler equipment, because you don't get injured hooking SC equipment up!
