I am heading for the same this week, I believe (Alan?) wrote to NOT use the flexplate but work on the clamp prying as close to the center as possible. I need to move mine forward by about 1-2 cm.

What you need to do is:

1) Loose the clamp bolt - green arrow (unfortunately you can see the bolt end in this pic).

2) Mark the flex to the flywheel then remove the 6 outer bolts - red arrow.

3) Slide the flex back on the shaft to about where it is in the pic and tight the clamp bolt.

Now, as Stan said, you can use a block of wood and a pry bar to move the shaft forward.
Try to pry as close to the center of the clamp as possible don't pry on the flexplate.

NOTE the less side loading of the shaft the better,
so you don't induce a bend into the drive shaft.

Of course, make sure the rear clamp bolt is remove before doing anything in front.
Hope this will help.

Hi,
I appreciate the help I’m getting. This is way past what I could do alone.
Learning as I go along, I have some more questions

I removed the flywheel lower housing and the flex plate looks good, no bowing.
I had loosened the clamp bolt thru the small bottom hole and did not take a measurement so I don’t know if it moved.

After removing the clamp bolt, I cannot move the clamp away from the flywheel. ?
(I did not remove the 6 bolts between the flywheel and flex plate after reading not to pry on it?)

Loosened the rear clamp but did not take the bolt off.
Also, does the rear clamp itself come off ?
Right now I’m looking thru the small bottom hole, I did not take off any housing.

When I get to moving the drive shaft forward, how do I align the rear and the clamp to the right position "... where the drive shaft necks down a bit..." on the drive shaft ?

Thanks guys

The pinch bolt behind the rear hole in the torque tube bolt has to come out. Otherwise you are not going to move the drive shaft. The correct position for the bolt is reached when it sits in the rear groove (that would be the tip of the red arrow in the first picture).

To move the shaft forward, remove the outer six flexplate (red arrows picture two) bolts that connect to the flywheel. Now untighten the flexplate pinch bolt (green arrow) and slide the complete flexplate assembly rearwards (direction to the tranny). Tighten the flexplate pinch bolt and use the clamp to move the shaft forward wit a pry bar.
Repeat until you reach the desired position. Which would be reached aproximately when the visible splines look like in the second picture.

Next I need to find the groove in the driveshaft for the rear clamp bolt. Am I in the ballpark?

Yes, you are in the ball park, but that is a picture of third base and you are looking for the pitcher's mound. That picture is of a slot in the rear clamp, and not the grove that is around the drive shaft. It is inside of that clamp and hidden here by the clamp. Take the bolt out of that clamp, as you have been told, and look inside of the bolt hole for the grove around the drive shaft. You may not be able to see it because of the problem you have with the drive shaft being in the wrong place in respect to both the front and rear clamps, but if you figure out how to move the drive shaft, as previously advised, you should be able to locate the grove around the drive shaft. When you do, center it in the rear clamp bolt hole and put the rear clamp bolt back in. Then you can put the bolt in the front clamp and tighten it in the correct location.

Is the bolt removed?
If not, turn the engine at the crank (clockwise as always) until you see the bolt head and remove it.

Then you're ready to do what's needed at the front as mentioned.
You will need to put the bolt on the clamp at the back only when everything will be at it's place.

Ron,

Don't know if you got a new one, but you need to replace the old pinch bolt since it should have damaged splines and you shouldn't re-use it.


HTH,

Here are some pics of the sleeve as it sits on the transmission to give you some perspective. The bolt MUST be in the groove. I had difficulty in getting it to sit when I installed a new transmission, but I had gotten a nifty suggestion from Stan who said to use a wire hanger bent to suit - it made it a breeze. Note in the second pic the sheen on the sleeve where the clamp sits. As others have said, replace the bolt with a quality grade. I'm not sure, but I think it is 12.9. Order one from our trusted vendors.

great picture, worth thousand words !!!!!

OK, I think I'm done.
I see the the groove in the sleeve as per the picture above. Got the bolt onto the clamp and tight. (I could not see any damage to the bolt).
I'm assuming that if the bolt is seated in the sleeve's groove then
things are aligned properly and I can finish up the front clamp.
Awesome help,
thanks.

Front clamp: this would be a great time to add the PKlamp and forget about flexplate movement in the future...

MainePorsche

Absolutely right.

Bertrand Daoust

+1.

Jerry Feather

Wrong. That is probably just where you were to start with. What you apparently have not done yet is move the drive shaft so that the grove around it is located in the grove in the sleeve. It sounds to me like you just took the bolt out and put it back without moving the drive shaft where it needs to be.

So far from you posts you still have the front flex plate bolted to the flywheel and can't figure out how to move the drive shaft. When you get on top of that that, then you will be able to make some progress in correcting your problem.

The diagram these guys keep showing you about where the rear bolt should go, the ones with all the BOLD RED marks and arrow show you two places where the rear bolt will fit, and your bolt is obviously in the wrong one. Get that straightened out and then your front splines will be exposed correctly.
