Vandoor motor sprocket HELP

[Drew_trak]

Hey guys!
So my team was planning on using the Van Door motors this build season; however, the output shaft is some really awkward size (maybe metric ). We were just wondering if anyone used those motors before and could help us determine which sprocket to use on the output shaft and where we could buy the sprocket from.

THANKS!

Is there a part number on these? Van they came out of?

A micrometer reading of the outside tooth diameter, and number of teeth would help. Try to measure root diameter as well. Shaft Diameter ?

Hard to help without some specifics.

Might be possible to replace the output gear with a FRC standard 20DP gear.
