D17 input shaft

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   hey guys, new to the forum here. I have a d17 gas and was wondering if a d17 diesel input shaft can be swapped into it. It seems to be the better option for swapping a 301 diesel in it so I don’t have to make a spacer in between the bell housing and adapter because the gas shaft is too long by 1” and 1/4 give or take. Or I could have the input shaft turned was another thought.

	Gas and diesel clutch shafts can be swapped, unless it is a series 4. Then, you have other issues. Be sure to get the diesel throw out brg shifter parts too as they are shorter than a gasser. When I did a 433-TI combine engine swap into a D-17 gasser, I cut the nose off the clutch shaft, and found a new pilot bearing that would slide on the splines that were left. Flywheel (12 inch clutch) pocket had to be made to fit the new pilot bearing. I also (memory) moved the flywheel forward some on the crankshaft and deepened the clutch friction surface too. This allowed me to stay with the long gas clutch shaft. I feel I had less labor involved that way and had a 100 HP clutch/flywheel inside the bellhousing. There's a thread from 4 or 5 years ago D-17 XT I think it was called with lots of pics.

	I will have to check out that post. So with that being said about series 4 being an issue mines a series 4 haha. What issues are there? I already bought the 190xt adapter plate a clutch and flywheel aswell. I bolted everything up and it seems that everything lines up correctly but the gap is a 1” 1/4 because the shaft is too long being the only big issue I can see which messes with the throw out bearing gap of course. I have a lathe and was thinking about cutting it and turning a new end for the pilot. Edited by Allisswapper - 1 hour 15 minutes ago at 10:54am

	The series 4 gas clutch shaft has shorter length splines for the clutch disc. All the older D-17's have splines that go rearward another 1 1/2" or so. How are you dealing with the hollow shaft to drive the hydraulic pump?? The length relationship between those two shafts has to be pretty close to original to work. A series 4 diesel hollow shaft must be shorter than a gasser, but AGCO parts books doesn't even list a diesel shaft, just gas and LPG. What are you doing for a pressure plate to drive the hollow shaft ??
