Major bang for the buck--shifter rebuild

[356robo]

I just completed a rebuild of the shifter mechanism in my 70 911 (901 trany).
What a difference!!!!!!!!!!!!!!! Of all of the maintenance I've done on this car, this process provided the most improvement of driveability for the least amount of money and time.

The rear bushings finally gave out last week so shifting became a challange. It forced me to do the repair.

Like the frog in the pot parable, the degredation in the shifting was so gradual that I really didn't notice until the rear bushings broke up.

Anyone with more than a couple of inches of play in their shifter should consider this cheap and easy process. The parts are cheap ($20-30) and the process is not real difficult.

On inspection, the shift plate was worn so I changed it out as well. That was the toughest part 'cus of the springs. If you do the shift plate, I can help with the process. I remembered a posting by another Porsche guy about this, but I can't remember his name. It was extremely helpful.

If you have any doubts, go for it. OK, I've rambled enough. Going back to my Corona now.

Hi 356 robo,

Any tips on getting the springs back in would be appreciated.

My shop manual had plans for making a "special tool" to re-install the reverse lockout springs. I used to have a scan of the drawing but I can't find it now (although it's posted somewhere on this forum). My scanner broke so I can only offer this iPhone snapshot:

You use it like this:

It makes an impossible job extremely difficult.

1. Clamp the shifter base plate in a vice (if you're in England, maybe you should cramp it in a vise).
2. Put the spring in position with the guide pin through it
3. Use the modified screwdriver to compress the spring so you can move it partially into the shifter base plate
4. Pull the modified screwdriver out of the spring and move the end of the spring into alignment with the hole for the guide pin
5. Find the spring after it flies out and repeat steps 2 to 4 as many times as necessary
6. Push the guide pin through the spring and through the hole in the shifter base plate
7. Put the clip on the guide pin
8. Rest after your ordeal and do the second pin tomorrow

Here is a thread over on the 912 board, with pictures, part numbers, pricing there is a spring and bushing on top of the shifter that looses height and force over time, check it out. Also a couple tips on the pin & spring.
And they are brewing Fat Tire in Asheville as well!!

Safety glasses for sure. Better yet, full face shield!

Its very easy, I just use a long pin punch that goes thru the hole and inserts into the spring so it can't fly. Gotta take a picture one of these times.
