I have a 1963 MM GT.  I think it is a model 100.  I am having problems with the clutch linkage.  There is a tab "thing" on the clutch shaft that rides near the drive pulley on the trans.  It appears as if it is supposed to engage the pulley at some point, but it has come loose, and the clutch is not working properly.  If someone can post a link to a manual for this thing or post a picture of where it is supposed to be and how it is supposed to work that would be great.

 

Thanks

Joe

Welcome to the forum! I hope this will help you:

If it does, I'll see if I can match an operators manual to it. Page 17 has the clutch and brake parts.

I don't have a picture atm but I'll try an explain it for now.

On those trans the stopping brake ( on right side) does NOT stop the input shaft (left side) from spinning when it is applied.

 

So what they did was put an adjustable piece with a small brake pad type material on the rod for the Clutch/Brake pedal.

 

When you step on the Clutch/Brake pedal (all the way) that brake material should move forward and contact the inner edge (at the front) of the input pulley. This stops the input from spinning. It is very important to be sure the input pulley is stopped before shifting one of these 3 speed trans!! One it will destroy it and two parts are near impossible to find for these trans.

 

Mine was missing the brake material so I just cut a piece of material in a wedge shape, drilled and counter sunk 2 small holes and riveted the piece to the little metal bar.

 

Good luck! And if you need more info or help let me know.

It had a little piece of brake pad adhesive on the metal and when you step on the brake /clutch. It will rub on the pulley and help it stop faster.
