Sieries III clutch replacement

YES IT CAN. all V 12's and 2+ 2's

So it cant be done on a 12cyl convertible?

ONLY on the 2+2 can it be removed, and, nothing needs to be cut.

I replaced the clutch in my 1970 E-Type 2+2 in the late 70's without pulling the engine. I learned of the procedure from an article that I think was published by JCNA or JANE. Anyway, the procedure is:
1) drop the drive shaft
2) cut a 2" diameter hole in the bottom of the bell housing with a hole saw. You can insert a socket wrench in the hole and access the bolts holding the clutch pressure plate to the fly wheel one by one by rotation the engine by hand. I think this was done via the universal joint at the rear of the transmission but I'm not sure. it was a long time ago.
3) Loosen the engine mounts and slide the engine forward as much as possible.
4) You should now be able to move the transmission rearward enough to drop it out. (Be careful, I found the hard way that the transmission is really heavy when it landed on my chest as I was lying under the car.
5) Do the clutch work. In my case, I removed the fly wheel (gives you a chance to inspect the rear main seal) and had it dynamically balanced with the new clutch. I also used a 10" coil spring racing clutch unit instead of the original 9" diaphragm clutch. (That replacement clutch is still going fine today.)
6) Reassemble everything using the same procedure (don't forget to slide the engine back in place on the engine mounts).
7) Make a nice aluminum plate to cover the hole and attach with small screws (at least this is what I did).

I hope this helps.

Does the same apply to the S2? The book says to pull the engine. I replaced the entire clutch assembly and had the flywheel turned 2 years ago and now I am starting to get clutch judder in 1st and reverse. I hate to have to pull the engine again. Thanks

Yes there is enough room to squeeze the gearbox out once you have every thing else out of the way.
