Central tube!!

So I'm trying to change my clutch out on my 82 924 I've done everything the book says to do. I'm stuck now. The picture is how much I've gotten it out so far.. I'm curious as to why it is so hard to get out. Any ideas?

Put a jack under the oil pan and make it so the weight of the engine isn't leveraging on the inner drive shaft. BTDT

Also, just for verification as "the book" certainly varies - do you have the transmission out of the car? I am literally in the middle of this right now.

And ensure you slide the tranny coupler onto the tranny, not the torque tube. I agree with the above in that it's critical to support the engine, and do it in a way that you can 'adjust' the engine's position, especially on reinstall.

So it is imperative that the transmission comes out completely and NOT with the tube still connected to it? The Haynes has lied to me. Again. Lol. I will disconnect everything then and try that. I appreciate the advice.

Actually I just reread the Haynes and Im Pretty sure it does say remove them separately. It just says it a little​ weird. "Remove the four bolts holding the central tube in place and slide the transmission and Central tube back to allow you to do the next step."

The factory service manual has you remove the transaxle first, then slide the central tube back.

The Haynes manual is a joke. Get the factory service manual if you are going to try to do the work yourself.

The biggest omission from a lot of those old references is that you must rotate the torque tube assembly over 180 degrees to disengage the safety catches in order to get it to slide back far enough. And, yes, the transmission needs to be removed. Impossible otherwise.

Yep tranny comes out. Shoot some penetrating oil through the bell housing onto the shift fork pin. You will be pulling that later n they can be stuck.

Okay so I took the transmission out. The central tube SPINS freely. My dad and I pulled it back and noticed that the shaft inside wasn't moving at all. I don't want to mess the groves on the shaft up trying to get it to budge. Any ideas? And also I took you guys' advice and got the factory manual. Told me exactly how to do it. Except for this problem. It's always something...

Alex, did you do this?

So, the 924 central tube (ake the "torque tube" btw) may not have those locking tabs requiring positioning - my year does not and you just slide it rearward. It also spins freely as you describe - no safety tabs get in the way of anything cause they're not there - just a smooth tube all the way to the trans.

You are not pulling the splined drive shaft out of the engine because it is binding due to the engine leaning and perhaps due to the rear of the torque tube (or front) not supported. SO that is your challenge - have someone lift the torque tube up and down to find the right angle while you are at the rear pulling directly on the splined drive shaft. If the transmission is off the vehicle you will be able to pull directly on the drive shaft and pull its splines out of the engine. Wear leather gloves for grip and careful as if it come out suddenly (mind was easy) it will pile drive your hand into something with enormous force. Obviously due care for vehicle being on jackstand and being under it as well. Use various combinations of lifting on the engine's rear and moving the torque tube. It will come out easily when you find the angle but if its binding, that's enormously strong binding with a 7 foot long lever (the shaft and tube) being out of line.

No safety catches/tabs on 924. Also, no shift fork pin.
Engine will tilt down in front and bind drive shaft as mentioned. See my post (and sausagehacker's) about being able to adjust engine angle.
