PTO shifter just flops around

[Bingo001]

I have a D 17. The shift lever just flopped forward the other day after I was done doing some brush hogging. Now the shift lever just rolls easily and doesn't engage the pto. The shift arm is welded to the shaft. Is this something I need to split the tractor for, or can this be reached from the top on the transmission? Maybe just put a fork back onto the coupler or something?

You probably sheared the roll pin that connected the fork to the shaft on the shift lever. So the sliding coupler doesn't move anymore onto the rear PTO shaft to engage. You can't access it from the transmission cover as it's not in that compartment, it's in the torque tube just forward of it. The standard method would be to split the tractor between the torque tube and the transmission to fix it. I have read some very enterprising people have been able to repair this by taking off the power director (PD) plate on the RIGHT side of the torque tube where the PD shift lever is. If Dr. Allis sees this hopefully he can chime in on the difficulty of trying this repair without splitting and how to go about it.

Maybe put a bolt with locknut in it to replace the roll pin?

Well this sort of just got discussed over on the "other" Allis forum. I can't link to it though or post a picture of what Dr. Allis said so I'm copying it here with credit to him:


My tool (which I don't have anymore) was a solid piece of 1 1/4" or 1 1/2" SQUARE steel stock at least 24 inches long. Drill a 5/16"+ hole in one end about 1/2" from the end. Install a 5/16" x 2" long bolt and use a nut to retain it. Place the tool inside the right side cover and place the tool up against the rear wall of the opening and the tip of the bolt against the pin while the PTO is fully disengaged. Strike the front face on the end of the tool with a 4 lb hammer to drive out the pin. Replace the pin with a gr 8 5/16" bolt and locknut using an air ratchet.
