Perhaps try those instead?
Width and diameter of the upper pulley are determined by clearance to the spindle shaft itself. So I'm stuck with the XL, 3/8" wide. But I believe I have it grokked using that belt calculator link that was posted here last night. A 140XL037 belt and a 26 tooth double flanged pulley on the bottom should be very close to the same center to center, and will engage 5 more cogs on the lower pulley, from 7 to 12. I like as that will slow the motor by reducing the step down from nominally 2.1 to about 1.2/1. That will put more pressure on the backgears which will be in low more of the time. But those nylon gears are all metal now, and should stand up to that. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
