Rejoining split tractor - Iseki

[loopman]

Hi all,

I split this little machine to replace the clutch linings on the independent PTO. There are 3 x shafts between front and back all to line up but all seem okay with a bit of fiddling and skinned knuckles, however I can't get the tractor to re-join, it stops with a bit less than an inch to go.

I believe I have worked out that it is binding where the front of the PTO shaft goes back into the housing. There is a small needle-roller bearing here that the PTO shaft enters, seems to be lined up and end of shaft is slightly chamfered to allow entry, I am just a bit hesitant to apply excessive force to get it to go together.

For those with experience in this sort of thing, can I just pull the two halves of the tractor back together (e.g. maybe by using a small hand winch?) or is that one of those actions likely to be deeply regretted!? (Photo attached - note that PTO clutch removed for photo, it goes onto splines)

If it has manual engagement lever, try engaging the pto, then put a crescent/spanner wrench on the pto shaft and turn it. You should be able to feel when it aligns into the splines. If you have a helper, each get on a rear wheel, and try rolling forward, jiggling it back and forth if necessary, and see it it rolls forward a bit. If lined up, it should move forward. You can follow up your progress, with threading the bolts in a bit, but still allow room to shake/jiggle the tractor, and move more inward. Usually if it starts, you can take it in threading the bolts in, but only with little or no pressure. Just keep trying to roll it ahead. You don't want too much pressure pulling it in, because you could damage the clutch hub.

Thanks DJ54, sorry I might not have indicated correctly, the spline are where the PTO clutch attach which I removed for the photo, it is going on fine. The PTO shaft extends through the clutch to be supported by this needle bearing. Haven't had a 2nd person available to help me push together and bolts not yet through far enough to start the nuts which is why I was thinking of a winch. Don't want to damage the bearing by forcing it too hard.

Do Not attempt to draw engine & clutch housing by tightening the bolts or utilizing force. Do you have each section with equal distance between top & bottom to each other? I agree to turn engaged pto shaft with pliers or wrench.

Do not force. Like TxJim said; check gaps. You might have to jack one 1/2 up a little to get the gaps the same. A smear of grease on the shaft end might help too.

Thanks everyone, well I ended up persevering and tried a little harder, assisted with a crowbar against the front bumper pushing the tractor together. Was quite tight but went together in the end and everything seems to work.
Cheers
