Today went to pull the shifter coupler on the GT and I found the head of the set screw was sheared off by PO. Explains why a hose clamp was on the coupler when the PO broke the set screw.
What are my options to get the coupler out without removing torque tube or transmission? Right angle drill? Help...........
To my cynical eye, you might have to try a 'nuclear-post-apocalyptic' solution. That screw is hacked, and center drilling it is going to be a beyatch.
Might be worth thinking about getting another coupling from 928 Intl and doing what needs to be done to remove that one. IE grinding the coupling and screw away to release the coupling.
I say that from my own perspective of not having a good track record with 90 degree drills and broken bolts.
Have already ordered a new coupler. Will use cut off tool to remove coupler.
Correct method.
Be patient and cut away just the coupler and the broken setscrew, without hitting the shift shaft. I do this in steps, like cutting up a turkey breast. You will get to the point where the coupler will move on the shift shaft and the remaining "pin" that goes into the shift shaft will fall out.
I never reuse these setscrews and always substitute the 911 part (901 424 229 00) for the 928 part. The 911 part is identical, except it has a nylon insert in the threaded portion to keep the set screw from working loose, so that it doesn't have to be tightened so tight.
And I have no idea why they made a different part for the 928 to do a worse job than the existing 911 part did.....corporate bullsh!t.

The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!

Ordered the 911 part. Definitely better alternative. Thanks Greg.
Received new coupler 928-424-029-00 believed to be from Porsche since I purchased it through a Porsche dealer. Two things are wrong with it. The pin which holds the coupler together is very loose and can't see why it wouldn't fall out once put into service. The second thing is the hole for the tranny shaft set screw has no threads. I have new set screws and they do not look like they are self tapping. The other funny thing is the part does not have the Porsche parts triangle insignia??
Any thoughts
Someone tried to rebuild that, looks like some of the crap I've pulled off of cars where "experts" have been working on them.
Roger's overnight a new one. Trying to make this weekend's car show. Haven't really debuted the Gt yet keep getting sidelined by different projects and redoing others' work.
