Alpha one drive sprocket measurement

2
Hi everyone !

Just Pick up some alpha one 2019 sprocket drivers 7t 3.5 pitch for a new project i am building with a alpha one track and suspension.

I am searching the distance between the two ifax slide on the mono rail and also the distance between the two drivers sprocket.

Thank you very much !

The space between the slide rails and space between the drivers are pretty close to the same. Unfortunately the last alpha I looked at before I built my single rail, I didn’t have a dial caliper with me to get an exact measurement. I spaced my rails and drivers about 3/8” apart. Just enough room to let the track clips space to move and not bind when the track tilts from side to side.

Thx for the pic. I couldn't wrap my head around a big thick 1.75 trackshaft diameter but now I see how they did. Only that big where the drivers are and less diameter otherwise. A cool weight savings.
