tranny won't fit all the way

My motor and transmission are out of my car right now. I went to bolt the tranny to the block and as I was sliding the input shaft through it just stope about 1/4" away from the block. basically I can get it to the guidepins, but that's it. I don't want to ty to force it in there but I don't know why it won't go in.
when I use the clutch alignment tool it goes in fine. I know it's for clutches, but doesn't it essentially take the place of the input shaft? Tomorrow i'll remove the bell housing and clutch again, but i'm out of ideas. Anyone else with this problem have any luck with anything?

I wish I could find the message(s) regarding the problem you are having. If memory serves me, it has something to do with the clutch TOB or linkage thereof. I hope this gives you something to work with until a real answer is posted.

Make sure the tranny is square to the bell housing, otherwire the input shaft can hit against the bushing/bearing in the back of the crank.

sure your input shaft is true? how did your pilot bushing look when you tore it down?

brand new pilot bushing. I think I may try and take the clutch off, and see if I can get it in there without the clutch. and if I can, I may try to use the input shaft as the alighnment tool. does that sound like a stupid idea? because if it does then I won't bother

Yes, that sounds like a stupid idea. :D Save yourself the grief. As stated above, make sure the tranny is squared up so the shaft is going in straight and also, make sure the alignment tool is all the way in. It should go in to a point where the round hoop on the end where you grab it is almost burried in the TO bearing. I ran into an issue where I thought the tool was in all the way but it was out by about a 1/2 inch and I couldn't get the tranny all the way in. Might have been because of my street twin because the disks weren't totally lined up, but something to keep in mind. Having it totally lined up plays a big part though.

Another possibilty is that your clutch fork is in the way and its hitting the TOB befor the tras is seated. Make sure your clutch fork is pulled out all the way.

well this is what I did today and i'm a little lost now.
I took the clutch off to make sure the input shaft would fit into the pilot bushing, and the tranny, bellhousing and block all mated up with no problems what so ever and was able to start threading bolts.
So I removed the bellhousing and slipped the PP and the disk on the input shaft. It to slid right into place when I tried this. I would have started to tighten down the PP but there wasn't enough room. So I now know it can all fit into place where it needs to.
I removed tranny and began to yet again tighten the clutch down with the alignment tool. the loop of the tool was just barely sticking out and you can remove and insert the tool with no resistance. But i'm still 1/4 inch away from it fitting up all the way. it must just be not lining up right or something but it's only once the clutch is bolted on it doesn't want to cooperate.

First make sure the clutch fork is pulled out.

Place the plastic alignment tool in the disk and bolt the PP up. Push the tool in the disk firmly, this will help ensure that it is dead centered as posible. The ring end of the tool will actually start going into the hole on the disk.

Bolt the PP up and torque.

Make sure you have the tranny balanced on your floor jack. Align it correctly up and down plus left and right. If it is aligned correctly it will slide in no questions asked. If it still wont go then check your alignment again. There is absolutely no need to force it in, it will slide in smooth as silk when you align it correctly.

The only thing that would prevent the tranny from going in would be a damaged disk but thats a stretch. IT WILL GO if these directions are followed just as sure as the sun will rise tomorrow. The key is positioning it prior to insertion.

Seriously, this aint hard to do. Take a break from it and try again later.

well I think I have come to conclusion that the input shaft is actually bent. How or when it happened i'm not sure. Without the bellhousing on I can slide the shaft in no problems, but with the bellhousing in place, the guide pins are off by a hair and only one side of the bellhousing mates to the block. with out the clutch in place everything fits up fine. I'm thinking it is bent a hair, but it's just enough for it not to work.

Now I need to find out how much that's gonna cost me to fix. at least the tranny is out of the car so that's a lot less work that needs to be done.

Are you trying to put the whole transmission in at once including the bell housing? If so, try bolting up the bell housing and then slide the transmission in place.

I had that problem with an auto tranny once..- the torqure converter wasnt in all the way..- but i dunno about a manual....

good luck though...

I tried it both ways and still had nothing. I dropped it off at a shop yesterday and so i'll see what they say about it.

Did you ever find out what your problem was?

Jeremy

not really. The shop called me today(the guy has been on vacation...of course) and he asked for the measurements of my pilot bushing. So I called him back with the numbers and he said he would get with me. Still waiting for he call back

The centering tool can trick you into thinking the disc is centered, even when it's not. If you put the disc and PP into place, thread a few PP bolts in but leave them loose, then slide the centering tool in, you will be able to move the tool around (up, down, right, left). I usually stick my head up in there and look down the centering tool so I can see exactly when the clutch disc is centered. Then I tighten down the PP bolts.

The centering tool doesn't get the disc exactly centered unless you take a good look while tightening up the PP bolts.

I to have had the same problem, the alignment tool went in fine but I couldn't get the tranny to slide in. It ended up the disc slide down just a little bit, so I loosened the PP and slide the disc up till it was flush with the top of the PP and everything went together fine after that. What helped me determine the disc was not completely centered was there was a very small imprint on the pilot bushing where the input shaft was hitting.
