There are no tags on front or rear of the differential. It has an 11 tooth pinion gear and 41-tooth ring gear and no one around here can give me a clue on how to find the gear ratio. any ideas would be appreciated
I may be way off here, but I think it's just a simple math problem.
Ring teeth / pinion teeth = ratio.
41 / 11 = 3.72I'm open to being corrected if this is wrong.
You're not, but to be pedantic it's 3.73 when rounded up correctly.
$ echo 41 / 11 | bc -l
3.72727272727272727272
No argument here. I should have thought of that.
Thanks to both of you. Really appreciate it and it sounds right
i know i already thanked you - mark and tom but i wanted to expand on that. you see we live in a small mountain town and it was going to cost me either $600 for the spare parts which would have to be ordered or i had 2 options. This is for the vehicle i use as a plow truck and without a plow truck we are in trouble in the winter (50 miles S. of Canada). I was going to have to either pay $600 and wait - and still not know the gear ratio, buy a used one (scary) or buying a $3500 truck. Since plows are so hard on vehicles there was never a question of putting it on my main rig. Just thought you'd like to know - what i need is in stock for $300 so not only am i saving money, i'm saving a headache.
