I have the engine out but I can't get the smaller drive shaft out that runs through the bell housing and into the power booster housing.When you pull on it it feels likeit hits something solid like a snap ring.I can't seem to find whats holding it. I followed the IT manuel but it doesn't go into detail.

Okay, move from the fron of the tractor to the rear. Look at the standard PTO shaft sticking out the rear of the tractor. The overhanging item directly above it is the PTO clutch housing. Remove the bolts which secures the cover. Remove the three bolts which secure the clutch pack. Now pull the shaft which drives the PTO along with the clutch pack out the rear of the tractor. Now resolve to never ever pull the engine again without pulling this shaft first. You may have bent the shaft when pulling the engine.

I hope this helps.

Glad to hear that the shaft was not bent! I hope the rest of the work goes a bit more smoothly.

Good Luck!

The smaller shaft is the PTO and hydraulic pump driveshaft. It must be removed from the rear along with the PTO unit. Paragraph 544A on page 56of my I&T manual is pretty clear on this. You should have removed the PTO before pulling the engine.
