911SC Shift Coupling Pin Removal help/tips

[TxGerman]

I’m in the process of replacing my shift bushings and am down to the shift coupler bushings. I understand that removing the pin can be difficult, but this pin just won’t come out (so far). Before I put any more force to it, I wanted to see if any of you have any tips or prior learnings you can share. I would prefer to not break it!

Any suggestions?

Support the coupling on a socket (or pipe fitting) and use a drift to punch the pin thru.

If i remember correctly, it has been awhile, the pin is knurled at the center to grab onto the male splined shaft. I just used a drift and clamped the steel bit with a set of soft jaws in the vise and used a deadblow hammer. Or did i support the black bushing with a deep socket and used a hammer.
Well i know i used a hammer!

This guy has a simple fixture, but I always use a socket. Of course with the fixture the advantage is not needing a third hand to hold it in place.

Wow! Mine has had much more force applied to it and it hasn’t even budged. Maybe it’s time to apply some heat?

Heat will melt the plastic bushings, try some penetrant overnight. They are tight and do require a good bit of force.

I have doused it with liquid penetrant, we’ll see if it gives up the prize in the morning. Thanks for the help....to be continued.

I clamp the square steel part in a vise and use an air hammer bit. Comes out easy.

I just repaired my shift bushings. I put the coupler on 2, 2x4s side by side and used a mallet and punch to hammer the pin out of middle. The 2x4s were perfect for the aluminum and the pin came right out

I just did mine. It took more force than the Youtube video guy lets on. Had to get out the 2lb BFH. Once it starts it comes out easily.

MTU (taking a page from Chris Balich, mid-Tuesday update):

After reading all the feedback, I went back into the garage with reinvigorated purpose. This coupler was going to either 1) come apart (willingly or otherwise) or 2) come apart in pieces, meaning more than the factory intended (which would be an excellent excuse for a Stomski upgrade). I tried a couple of similar setups as described above. Ultimately, the successful formula included a 19mm impact socket (as the base) rested on a 2x4 and a steel rod (coincidentally the perfect diameter) and then a hand sledge. After several forceful blows, the pin succumbed and gave up. Voila! The bushings were properly destroyed, but that's an obvious non-issue.

Now, to get back to the original job at hand....to improve my shifting feel.....

Thanks to all for your input.
