40 divided by 13 = 3.0769 ~3.08

my ring was 41 and my pinion 10

if u devide the ring by the pinion u get the ratio....

if anyone has a 3.55 could you count the teeth to verify, thanks

Click to expand...

dividing the ring count by the pinion count tells you ratio, no matter what ratio they are.
