Shift linkage bushings

Well the bushings in my 69 are non existent. I just got in the bushing kit and the front two are pretty straight forward. The back two are the ones I have a question about. You have a pin the runs through the center of the bushings that has to be pressed out the pressed back in. Has anyone been able to do this with a c-clamp or vise? I don't have a shop press and would prefer to do for my self. Thanks

There is a pin that holds it together

James,

The rear one is easy. However, the instructions I have read recommending a press are a bit intimidating. One book recommends to just buy the whole rear shift coupler as a unit due to it being much less difficult and "only about 50 bucks." Now they are $85 and more so replacing the bushings only for about $15 makes more sense.

To answer your question, I used a vise with just enough pressure to hold the coupler without damage and tapped the pin out with a flat punch. Wrap the jaws of the vise with a rag to prevent scratching. If you don't have a vise, you could lay the coupler flat bridging two 2x4 blocks of wood to raise it off your work table and give clearance to drive the pin out. I installed stock bushings and was able to push them in place with firm thumb pressure. Took 10 minutes. Best >$50 bucks you'll spend on your car. Go for it!

I've recently replaced the bushings on the gear linkage on my 78 SC. I found the hardest part was replacing those bushings in the coupler. I found a youtube video on someone doing it that was useful (https://www.youtube.com/watch?v=LAD0PoC8mzo).

Here are some shots of how I did it:
How I held the coupling:


I was actually preparing to drift the pin back in here; forgot to photo the drifting out. It's OK to drive the pin in and out provided you hold the splined part as the interference fit is between the splined part and the pin; it's a free fit in the bushes so the aluminium? housing is not stressed. You have to use a drift and hit it quite hard before it will move.

I found installing the new bushes a bit tricky. First can be pushed in but second one needs to be levered in. I used first one spanner (wrench) and then a second one and finally a screwdriver between the two spanners, like so:








Finally a shot of new bushes installed showing that there is fore-aft play in the bushes. I'm told by a Porsche specialist that there should be some fore-aft play otherwise gearbox may jump out of gear. Guy in the youtube video seems to suggest that there should be no play but don't think he's right. The bushes I fitted were not round but slightly elongated to allow the fore-aft movement



Hope this helps

I easily replaced my coupler bushings recently without a press or anything specialized. In my case the old bushings were completely gone so removal was easy. I did have a B&D Workmate that I used to clamp the coupler housing and tap the pin out with a drift. I put my new bushings in the freezer for a while before installation, and slipped them most of the way in by hand. I got them in the rest of the way using either the wrench method photographed above or slip-joint pliers. Pressed the pin back in using the Workmate. I think the whole job took me about an hour and a half, including removing and reinstalling/adjusting the coupler in the car, and I was taking my time.

Thanks for the tips guys. I read the pelican tech article on changing them. And it says put the car in first before you remove it. My car won't go into first due to the bushings being gone. I know this is to help get it back adjusted quickly but will it be that difficult to adjust with it left in nutral? I'm hoping to tackle this here in a few hours. Thanks again

For the adjustment read this tech article:
Pelican Technical Article: 911 Shifting Improvements

Main issue I have had in the past is that after adjustment it was possible to catch reverse in coming down from 5th to 4th. If this happens it means that you have to lengthen the shaft by slackening the coupler bolt and GENTLY pulling back on the shifter a SMALL amount, re-tighten and road test until you get it right. Happily for me I got mine right first time after the bushing rebuild and the change is the best it has ever been.

Thanks. My 69 has a dogleg spring-loaded 1st so I guess I would just pull it all the way over "compressing the spring". The artical sounds like it's for a tranie with 1st and 2nd all the way to the driver side.

How could your shift that targa???

I like the Wevo coupler a lot. Expensive but worth it.

It only had 2nd and 3rd. Reverse was my two legs. I've only had it a month or so. It would start and "drive" when I got it but not idle. With help from pelicans I got the carb sorted and she runs and idles great. Now I'm getting her tranie sorted so I can get her on the road. I plan on doing the wevo later just need to get her going right now.
