High speed gear tooth count?

Post by BUSHMIKE » Wed Jul 19, 2023 7:59 pm

Does anyone know the gear tooth count on a TT high speed worm gear, pn 1044B? Not the worm. Counting teeth in the artwork, The parts book shows (29) for the std gear and (31) for the high speed gear.

Never mind doing the math with the 7.25:1 and 5.16:1 ratios, the tooth counts do come out 29T and 31T. I’m impressed that the actual artwork is correct!
