How do you figure out gear ratio?
Hi all
Is there a way to figure out what gear ratio a ring and pinion set is by looking at it? Is it stamped somewhere? Can you count gear teeth? How can I find out?
Thanks

Anyway, the number of teeth on the ring / the number of teeth on the pinion = the ratio
for example:
a 36 tooth ring and 11 tooth pinion = 36/11 = 3.27;
41/11 = 3.73;
41/10 = 4.10;
Here's a chart of the common combinations...

If they are OEM gears it will also be stamped on the face of the pinion gear.
Here is a pic that shows the one on the left is a 2.73 than a 3.55 and a 4.30 pinion
You can see where the 2.73 and the 3.55's say the # because they are OEM
