911-type gearbox ('70-71) stuck on my siezed 2.2 engine
 
I did a search about the intricacies of splitting a '70-71 911-type 5-speed gearbox from the engine in my 1970 911E. This is the best thread I could find:

Using this and the Haynes manual, I'm still confused as to what I should do. "The fork on the trannie needs to get disengaged from the throwout bearing." Does this mean the clutch fork needs to be moved towards the engine or away from it?

Adding even more complication is that my engine is seized, so I cannot rotate the flywheel to see the rivets as instructed in the Haynes manual, and I don't know if it will be possible to "rotate the throwout bearing" or flywheel propery as instructed in the above thread.

What can I do? :confused:

Not a huge problem - you actually need to rotate the release bearing with a large screwdriver. The bearing has a couple of 'ears' that engage the fork. You can peer into the area from the top - the bearing needs to be roatated 90 degrees - it can be done without using the Haynes manual method with screws,etc
Hope that helps - I can get some pictures tomorrow for you if you are still stuck

as noted above, no need to mess with the screws. just pull the fork arm firmly, so the fork moves away from the T/O bearing, toward the engine, and then rotate the bearing 90° with a screwdriver.

Finally figured it out...had a hard time understanding how the shift fork works. I was trying to wrestle the "handle" end of the fork, moving it towards the engine, but that was actually levering the fork end away from the engine. The #$@% bearing wouldn't move. Finally I pushed the fork lever in the complete opposite direction away from the engine and the bearing rotatated easily and stopped itself at 90 degrees. Then the fork had no more tension on it, and the tranny slid off like butter. This was much easier than I made it out to be...the hardest part for me was the concept of how a clutch fork works.

Another quirky 911 lesson learned! Thanks for the help!
