a7 reverse catch lever - Vancevr - 10-02-2021

Hi I have a 29 chummy and I would like to make a reverse gear catch like it would have had on the gear lever. Could anyone help me with some pictures and/or maybe some instructions/suggestions.

Hi,

This is not on an A7 but as your question is quite open here's what I made for the same purpose on my Sandford's gearbox.

The reverse is left/front and the first rear/front so I was really afraid to break the gearbox if I missed the 1st to second.

Hope this help.

Of course the gear lever is very short and that allows me to push with my little finger to unlock.

Here you go. Made from German Silver about 3/64" thick I think. 1 1/2 inches across at the widest part, 1 3/4 inches from below the rivet to the top.

Worth keeping an eye on eBay, sometimes chopped gear sticks come up or even a reverse catch.

Thanks to both of you I will keep an eye out for one and will see what I can whip up.  Big Grin Another question I forgot to ask is how does the bottom portion work?

Ah! Another photo required but it'll have to wait until tomorrow to venture into the icy garage!

That looks like a beautifully original interior!

Here you are:

The first two show the catch raised and in reverse, the third is in neutral.

The guide housing often remains, rivetted to the gearstick. There is a small coil spring inside to pre-load the catch. 

I've reproduced the brass piece from a piece of (I think) 1/4" brass plate with a file, doesn't take long even with a few duff attempts first.

If they needed a reverse catch on the early 3 speed boxes why was it deleted on the later ones?
