hi i got an 88 here that i thought the clucth went bad on but after a few minutes of looking at it it turns out that the two bolts on the clucth side of that coupler came out so i figured i coould just push the shaft back in. if i remember correctly the shaft just has splines on it that go into the clucth but i cant get it to go far enough. i was hoping to be able to put it together without pulling the bellhousing of but its starting to look like i cant. any ideas? thanks. tim

I had the same problem on my 77 recently. You need to block the clutch pedal completely down with something (I used a 2x4) or have an assistant hold it down with their foot. Then work the shaft forward & into the splines on the disc & into the pilot bearing. Then work the coupling into the proper place on the splines. It has a special place on the spline where a little bolt goes through the coupling & part way into the spline. Then install a new pinch bolt. Some have 2 pinch bolts. Use a grade 5 or better bolt. After doing that I also spot welded my coupler in place so this wouldn't happen again. It was about a 45 minute job & only a minor PITA.

This is just a guess so take it for what its may or may not be worth. If the shaft slipped back and you pushed the clutch pedel down the disc may have fell down a little and that would stop you from being able to put the shaft back in like it should be. You maybe able to push the clutch pedel down and then work the shaft up or down some and get it back in. But like I said this is just a guess but we used to install trannys in a chev truck by pushing down on the clutch pedel and moreing it up and down some till it popped in

You're not as lucky as I was with mine. When it happened to me I was able to immediately see the problem. I pulled it back to the shed where I keep the tools with my other 77. The clutch disc is what comes out of alignment and not the bearing. I just blocked the clutch pedal down & fooled with the input shaft a while & it went back in. You need to take a good look at the end of the clutch shaft & the splines on the shaft to make sure it didn't spoil them when it came out if you do indeed need to disassemble it. Also, I hope it doesn't have a belt pulley unit. If it does you will need to unbolt the engine & move it forward several inches or lift it & place it crosswise on the front tub. The only advantage if you have to do that is that it's easy to work on once it's in that position. Even then, these tractors are not hard to work on. It's just a time consuming PITA. Hope this helps.

Well since I have never been in to one of them all I can do is guess but yes it is possiable that it could happen. I know on a 60 it can happens since I have something sort of like your problem on a 60 engine I have

Shot you should try to do the things I do. I have something like 25-30 tractors and they are almost all the colors that are common so I never seem to get real good on just one brand but learn a lot about them all and sometimes it gets hard to remember which one is set up which way. LOL. But it is all fun/work depending on if they brake down or if I just got a new one in.
