Figuring out my transmisson gear setup

[CR MAD MAX BUGGY]

Hello,

I wanted to know if there is a way to figure out what is the gear set up that I have on my dune buggy.

I know it has a 4/12 Ring and pinion but I wanted to know if there is a way to identify the gears inside the transmission WITHOUT taking it appart.

It should be the same as a beetle 1971 that was used as a donator but I cant assure that.

I appreciate any tips.

Thanks.

Take all the spark plugs out of the engine, to make it easier to turn the engine for the following procedure.

Jack up one side so one wheel is off the ground. Mark that one wheel with a piece of tape with a corresponding piece of tape or a mark on the ground for reference.

Put the trans in whatever gear you’re trying to figure out the ratio on. Mark your crank pulley and count the exact number of turns it takes to make the one wheel that’s off the ground make TWO full rotations.

Divide the number of crank pulley rotations by 4.125 (your stated ring and pinion ratio) and you’ll know your gear ratio for that gear.

Repeat for each gear.
