Its Usually not that easy. But easy in a different form. Usually da teeth count is stamped on da ring gear. Devide one into da other and thats da answer. Or count da ring and pinion teeth yourself. Easy peasy.
Somewhere on the circumference of the ring hear, the numbers 41-10 should be stamped- - - -41 tooth ring gear, 10 tooth pinion, which divides out to a 4.10:1 gear ratio. Other brands of gears (not GM) can have a 9-37 tooth count, for a 4.111111 ratio. Jerry
The murder victim was drowned in a bathtub full of Rice Krispies and milk. The coroner blamed the crime on a cereal killer!
Cringe and wail in fear, Eloi- - - - -we Morlocks are on the hunt!
Somewhere stamped on the Carrier you will find the Identification Code. Example, a 1967 C20 with 4.11 ratio would be stamped "HW". Note these codes were not always the same year after year, so get the code and report back so we can help figure out what you have.
The 4.11 ratio would have a tooth count of 37-9 (stamped on the ring gear)...37 divided by 9 = 4.11.
I got one!!!! Finally! I found in Wausau Wisconsin. I had to go for a 2-1/2 hour drive yesterday. I am so stoked. And it only cost me 125.00 bucks. I could have gotten one in Iowa. But that would have been a 5 hours away.
I finally got the chance to switch out my 3rd member in my 53 3600 3/4 ton truck last week end.I got my 4.10 gears now!!!! Woot Woot. I took the truck for a spin last night. No more screaming down the road at 50 miles an hour. It was a great day. I am so stoked!!!
Its a odd test drive. You know it’s different but its not a huge difference on paper or even seat of the pants but its just enough of a difference where it really does tame the rpm down. Im running a LS so mine can rev cross country at 5k if i wanted to without worry but i can see how on a old straight 6 it probably makes a much more noticeable difference.
