Ok got the transmission in place. Bell housing and mounts are in place and bolted together. Slide the coupler from the trans onto the drive shaft. Then I can only get one of the bolts through the coupler. I can only get the slots to line up on the transmission side of the coupler. What the heck am I missing? ARRRRRRRAAAAA!!!!

I have done this before and do not recall having this issue. Should there be some kind of gap between the two shafts. The one on the tranmission and the one from the torque tube? The shafts are right up against each other as it is now. There is no way the holes will line up as it is.

WHAT DO I DO? HAYNES SUCKS ON THIS!!!

Help if you can.. please.

Thanks

This is why, I do this with the torque tube out, a few extra bolts and alot less hassle. Easier to slide the hole thing into the back of the motor than to fit with the tranny.
As for your problem I would guess you tans mounts are alout of alignment? Did you put in a different trans than what was in there?
And yes, the tranny sahft and the torque tube shaft do sit close, Not sure they are suppose to be that close. I would guess something isn't aligned right, Let up know how it turns out?

They are the same engine, toque tube and transmission that came out of Nicks car..... also used the same coupler. DOUGH!

Well I guess I will take the trans back an bit... align the shafts and then bolt the trans back in. Ah the pain.

If you are goping to do that, you might find putting the coupler onto the trans may halp with the install. You only have one side to mess with then.

It was on the trasnmission when I started. I just do not understand why they chanel does not line up. Everything else lines up. It is simply distance that is he issue. The splines are lined up. Mounts are in, bell housing is bolted together. What the heck!

I am not itching to do anything but drive the car.

Hey Eric,
Not a big deal, but a pain-
The torque tube shaft must have gotten tapped forward or rearward. It doesn't take much to push the shaft enough in any one direction so that the coupler bolt won't go in- it is just a light press fit into the torque tube bearings.

Haynes has a measurement for the length of the shaft that needs to protrude from the torque tube bellhousing. You'll need to pull the trans back out and either tap the shaft in a bit or pull it out a bit. I did it once before with my old torque tube.

good luck!

Put the bolt through the coupler on the torque tube side then gently pry against the couple to move the torque tube shaft. From the sounds of it the torque tube shaft has to go towards the front of the car.

I have several torque tubs here out of cars and even got some bad ones, but none have shafts that move back and forth. And if the torque tube is bolted to the motor bell housing doubt it will move much either. Very interesting. all the trans I have taken out and never noticed a shaft moving? Is it supposed too?

the shaft in the tube must have moved, you will have to pull the tranny and attach the coupler before tightening down all the bolts, I have done this myself so i know what a pain it is, although my shaft moved forward

No the shaft isn't suppoused to move fore and aft. It's not that difficult though to cause it to move some when doing a clutch it's only a light press fit unless you are trying to get it out then it'll be rusted in there. On my 24 the shaft would move 6 inches or more I think a bearing race seperated allowing that to happen I'm trying to find someone familiar with torque tube failures to look at it since I also had a new clutch come apart and a vibration problem I would like to know what caused what before going back together. I'm still trying to get the torque tube bearings out to examine them.

just another good reason to remove everything instead of fighting with it.

DOUGH!!!!!

Ok so either I pry it forward or... think this is better... Back off the trans get the bolts to line up and then use the tran bell housing bolts to push the assembly forward as I tighten them up.

Man what a pain. Figured that was the problem and that was what I was going to do next. It is just good that I got some comfirmation. I would have hated to get.... "No way the torque tube is now junk".

I feel better..... even though it means another night of freezing my fingers and toes under the 924. At least it is the final bit needed before I put the exhaust on and... hopefully fire the car up!!!

Yeah, as I recall the procedure to move the shaft involves a large hammer and a block of wood... plus a couple of rulers to measure the offset.

Definitely sounds like that's the problem.

Everybody take a deep breath. Please.

Yes, the driveshaft will move. Fore and aft. Some easy. Some not easy.

And, we have one that we finally ran a drill through to get some 'clearance' for this same problem. It doesn't take much to keep that bolt from sliding in.

Ok it is done. Was easy.... some what. I just did what I said above. Backed off the bell housing bolts on the trans and slid the trans back. Then pushed the bolt in... torqued it and tightened the bolts on the trans housing. Bingo all set now!

Thanks everyone for the support!

Now on to the muffler. Too bad I am taking it off the road to save some insurance money. I bet the 9.3:1 motor is great!

Thanks again

Eric
