If you mean the shaft from clutch plate to the t/a sun gear shaft? May have pushed the pilot bearing apart in the flywheel when joining the split. Or somehow pushed the splined coupler on the clutch shaft forward on the shaft. Can you see splines on the clutch shaft behind the coupler? coupler should be far enough back when looking through top to not see splines on the shaft. Even if the pilot bearing is apart I can't remember if the clutch shaft will slide far enough forward to disengage the coupler with the pto drive shaft and gear in place. Can't remember if it was 300 size or the bigger tractors that IH started turning the clutch shaft down closer to the coupler after problems with the bigger diameter contacting the PTO drive shaft. They are pretty close. That's why I'm not sure the shaft would go forward enough to disengage with pilot bearing bad. Also would take a good bit of pressure to push the T/A shaft back. Pretty stout snap ring or bearing would need to give. Anything could happen if bolts were used to draw together. Later IH added a internal ring to the splined coupling to keep it more centered on the splines. SMTA didn't come with the ring. Never saw one get completely off the splines without the ring though. Sure sounds like the clutch shaft pilot bearing is damaged even though I can't remember if the shaft will slide that far forward. Just things to check since I can't remember the clearances.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash.

The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
