The pinion for the PG71 and PG188 is 0.6 module, 17 tooth.

17T 0.6 Module 0.125 in. Round Bore, Steel Gear

I know the PG27 pinion is 11 tooth, and as I posted below, the numbers work out for it to be the same pitch/module.

AM PG Gearbox actual ratio

This isn’t about motors, but AndyMark gearmotors. It seemed close enough to post in this forum. For some time, it has bothered me a tiny bit that AndyMark does not publish the actual gear ratio of their PG27, PG71, and PG188 gear motors. Before the PG# were available with encoders, it was no issue at all, but now that they have encoders on a back shaft of the motors, there are certainly use cases where you might want to go multiple revolutions and know exactly which direction your output shaf…

Added: I see that @andy_baker d; that sounds like confirmation.
