Gear ratio of hydro rear
 

I have a question for those with a little more experience. Does any one know whatr the final gear ratio is for a 782. I mean the final drive in the transaxel I have a alum rear and a cast rear I'm trying to see if all the hydro rear have the same gear reduction,
I appreciate any help with this info. Its foir a project that I'm working on.

The aluminum and CI rears have the same reduction as long as they are both out of a GT. The SGT tractors have a slightly different ratio between the hydro output and the driven reduction gear. Also, the ring and pinion gears are straight cut on the CCC aluminum rears and helical on the IH CI rears.

Gear ratio's ?
 

Back in the day, no tag found on car rear ends. To determine final ratio U count the # of teeth on ring gear devide into # of teeth on pinion = final ratio. Don't know if that helps.:banned:

That would work if not for an additional set of reduction gears between hydro output and the differential input pinion shaft.
Similar to the model A's style/ or quick change in sprint cars

Hydro rear ratio
 

Thank you all I did the old school od counting ratations but there is some diffence as i was counting and the background on the rears I'm collecting for is for matching to front axel ( I am working on a front whell drive assit for my 782"s or 82"s with hydr unit my 582 the unit is going nto need some tweeking. Now you see why i need to have exact numbers any diff is going to reek havock on the mechanicals.
Thank you everybody
i really appreciate any and all help
I'm doing this on a cad sysyem so anybody that wants can copy or change if you have better Idea.
