I did a similar mod on my first Spyder after having 3 VW bushings fail within 2 years due to the extra side thrust caused by the shift rod offset required by the system....

A machine shop let me turn down a piece of Naval Bronze to replace the stock bushing...  The bore was .015" oversize to allow for movement of the transmission nose cone during operation, and the lateral linkage movement caused by the offset bends...  When installed, it removed all slop within the system and was still on the car almost 7 years later when it was sold...  The only maintenance was a squirt of oil at each oil change, which was probably unnecesary....  It actually shifted better than the BIG BUCKS cable system that came on Spyder # two....

I just did this install on my CMC using a similar bushing my shop let me have for free. It was a pain in the A$$ getting it in. What ended up helping me install from the front was using a medium binder clip (for hold paper) to hold the bushing in place on the hanger. Then using small snap-ring pliers to install the clip. The bushing can be installed in either direction, so you don't need to cut the tunnel to get to the back. Took many, many attempts, but I got it in there after a few beers and some swearing. Shifting is really smooth, but anything installed would have been better as my bushing was toast (in half in the tunnel) when I bought my CMC.

Leon, my Vintage Spyder with rod shifter has a heim joint behind the shift box BECAUSE of that sideplay. No, it doesn't vibrate Tom, but like Leon said, if it did you wouldn't hear it anyway!

 

Carl, yes, pretty much the same procedure, although the 911/912 has a pretty good sized access hole in front of the seats and under the carpet!

 

IMHO, that cheap factory bushing is responsible for too much frustration. Brass sounds like a great idea!

Shift bushing install, use a long 3/8" extension and set that into the bushing hanger hole, drop the bushing over the extension allowing it to slide down to the bracket, slip the busing into the bracket with a screwdriver being careful to not damage it and it should go right in, lube the inside of the nylon bushing and work the shift rod back into the bushing using long needle nose pliers to slide the rod along.

Toasting meaning the nylon bushing had worn-through enough before I bought my speedster that the ring clip was the only thing left on the shift rod tube. I found 2 halves of the nylon bushing in the tunnel floor. I've read here that when the nylon bushing wears out, it just splits into. I was having trouble shifting when I got my CMC and found this advice here on the forum to check the bushing.

Are the symptoms of a 'toasted' shifter bushing intermittent difficulty engaging either first or reverse gear from a dead stop?

 

If so, is the replacement procedure and bushing for a 912 the same as the VW?

 

Thanks, Carl

It took me a while after I put my transaxle back in to get it to shift as I wanted it.  

 

I like to just pull the shift lever over to the left stop and haul it into 2'nd without having to think about it.  

 

When I first put everything together I had to hunt to find 2'nd by pulling to the left stop and then going right just a skosh and messing around to find the gear.  

 

Definitely not cool.  

 

Had to mess with the lever base position a couple of times til I coerced it into submission.  Now, I'm back to thoughtless downshifts and can concentrate on missing or scaring unsuspecting pedestrians.
