A) Is there any way to tell what gear set is in a final drive looking only
at the outside?
B) Do all the 'newer' gear sets fit inside the old case with no
alterations whatsoever?

I think the answers are A=No and B=Yes

So what should I be counting to determine the gearing after I remove the
cover?

Tks

Mike in NS..who unfortunately will not likely be leaving for anywhere this
winter!

Mike,

Count the number of teeth on the ring gear and divide it by the number of teeth on the pinion gear. It might be hard to see the pinion gear to get a count. Another way is to rotate the ring gear and count how many revolutions the pinion gear turns. For instance, just a little over three turns would be a 3.07, a little over 3-1/2 turns would be a 3.55. etc.

All our units are identified with the ratio # stamped on the flat
machined surface on the face next to the cover.

Thank you. I knew it was about counting something but had forgotten to
divide...<g>

as we would like it top be.
Jim..tks for the tip..I'll look there first

FYI
Just in case you have the 3.21, here is how to identify it.

The only one I'm sure of is that it isn't a 3:21.
It appears I have a collection of final drives and thought I'd see just
what's what.
Thanks

Mike

Mike,

I think you'll find the teeth count on the ring gear. Useful if you have
trouble counting only once around. :-)

Ken

I have trouble counting using my fingers and toes and if I forget to take a
shoe off, ....well, it's just plain inaccurate! <g>
