Looking at the pics in the manual and which gear meshes with which, I get
52/24*39/19 = 4.44736......... The 32t is actually the spur that meshes with the motor pinion so I didn't use that to find the internal ratio.
Different pitch gear doesn't affect the ratio calculation. Only the number of teeth do.
Oh guess I took too long looking at the manual. Lol
