Clutch Job Time on 968 vs 944?
In another thread a comment was made about the amount of time required to do clutch jobs, but since I don't want to derail that thread, I'll start another.
Summarizing, here's how long it takes to do a clutch job:
968 - 5 hrs
944 - 16 hrs
Why the big difference? What exactly was changed? I'm not too interested in the 951 times. I'm looking at getting an S2 or 968 and to me this shorter time requirement makes the 968 more attractive.
Thanks!

The bell housing on the 968 was redesigned, and an acess plate was added that lets you get to the clutch without having to drop the tranny and remove the torque tube.

Wow. Thats worth the price of admission right there. Anyone have any pics? I have a couple bellhousings I might try to modify....

The bellhousing on the 968 is deeper to accomodate the dual mass flywheel and thus the torque tube is shorter as well. It can't be directly swapped into a 944. Besides having an access window to get at the clutch, the shaft in the 968 torque tube is 2 pieces which allows the "nose" of it to be pulled back and out of the pressure plate. 944s really should have been designed like this since day one.

The 968 system can be installed on a 944 but you'd need to do a lot of work. The TT, bellhousing, DMF, PP, clutch, speed sensor, and hall sensor will need to be transferred over. And who knows how many other electronic things. The hardest part will be custom fitting a hall sensor to a 8v motor.
It might be easier to just cut a hole and machine a custom bracket for 2 speed/ref sensors in the appropriate location, and make a spacer for mounting a 944 flywheel at the same distance away from the motor as the DMF. But I doubt the 944 starter will work but it might.
Yes, the 944 should have been made like this. The 928 is like this.

I'm curious about how that shaft was designed. Do you have any pictures of how that works? What keeps the shaft from pulling out while it is in operation? They have to have some kind of locking mechanism, right?

The 928s have the same design also. The problem is the 968 clutch parts cost. Its a good bit more than a 944 when I checked last. Also, this is the reason why I criticize the retarded engineering done on the 944/951s since the 928s had this design back in the 70s.

Funny you mention that...... The blue 968's clutch has gone in and out twice in the last 2 months. I would have gone crazy if I had to drop the tranny and move the TT both times. And the red 968 is slated to be converted to the 944 bellhousing (in order to support an 8v turbo computer). So I might have an extra 968 bellhousing laying around. We'll see what happens.
