67 and older 4 speed shifter restoration


 

 

I've decided to make an attempt at "tightening up" an original shifter for my 66. This is the same shifter body that was used in Canadian Pontiacs, Beaumonts, Acadians, numerous Chevrolets and I think maybe some Buicks prior to 1967. 

I have it all disassembled and need to order some parts for it. For now I'm just going to post the pictures because I don't have time right now to do a detailed story but that will follow.

So this is pretty much what you start with, one of the most basic 4 speed shifters anywhere! And it's pretty famous but with a lot of people, not famous in a good way. I personally like these shifters. With a little bit of practice they are fine for full throttle shifts!

Note in this picture I have removed the 1/4" horizontal pin at the top of the shifter. I did this previous to any of these pictures being taken. It is welded in place, so it took some grinding and a hammer/punch to remove it. This is optional, you'll see in a bit why I did this. It's the first time I've removed that pin on any of the many shifters like this I've taken apart.

Taking it apart is pretty simple. Start by removing the snap ring on the pivot shaft that runs through the arms and the body.

Grab the other end of the shaft and pull/twist/wiggle the shaft out of the housing.

Once it's pulled out, again, twist/pull/wiggle  and remove the whole inner housing and arms as a unit.

Then strip down the part you removed. It will all just fall out.

Remove the clip and remove the 1/4" pivot pin that runs front to back, then pull up on the inner part so the convex washer can fall out. I removed that top pin (as mentioned earlier) to I could take the convex washer out and do a better job cleaning and blasting the whole unit later. The convex washer creates friction so the side to side slop isn't so bad on the shifter when it's in the car. You can see the beveled area that it sits in on the inner part of the shifter.

Notice the 1/4" pivot pin and the big pivot pin both have visible wear on them. I plan to replace them both as I would imagine some of the slop in the shifter would be created by that wear.

When I took the convex washer out, it was almost flat. I don't have a "before" picture of it. I had already reshaped it and reassembled the shifter body prior to any of these pictures but here is how I made it more convex again to create friction in the side to side movement. I simply used the shaft from one of my pullers and set the washer on a piece of pipe the right size, then some hammer persuasion.

That's it so far, more to come much much later when I get replacement parts.
