That's odd. The part number on my Eagle 10 rear end is A2312V386. Nowhere can I find anything even close in the list I copied. I've been told it was a 3.73 rear end, and I was hoping to find out for sure with this list, but I'm still not sure.

Anyone know where else to look for numbers on the rear end? My tag was welded on about half way between the carrier gears and inside wheel. I can't seem to find any other identification on the differential.

I believe you will find those numbers on a metal tag, riveted to the third member, at least that's where the tag is on mine.

Is you axle a Rockwell?

That's where I got the number. I assume it's a Rockwell. Where would the name be stamped on it so I could tell for sure?

The number either stamp or tag-welded on drive-axle’s housing is usually parts # of housing unit.

Most all truck & bus rear-end ratio ID are on tag (metal or paper) attach onto one of punk-kin’s bolts.

About brand names, Rockwell, Meritor and now it is ArvinMeritor

http://www.arvinmeritor.com/about/history.asp

Brand names of truck’s parts manufacturing companies;
http://www.freightlinertrucks.com/parts-service/parts/alliance-brand-parts/strategic-suppliers.asp


As usual most bus may already have punk-kin exchange for either worn-out and or ratio change to meet their needs. However they may not leave a marking or tag with ratio number.

You can easily check ratio;
1) Chock front or grounded dual wheel
2) Transmission in neutral
3) Release parking brake
4) Engine turn off
5) Jack up one dual wheel up to turn freely
6) Have someone or you watch the drive-shaft while turning wheel
7) Mark dual-tire with chalk for index
8) Mark drive-shaft with white paint or chalk (attach to long stick with electric-tape)
9) Number of dual-wheel turn is halved the ratio of drive-shaft due to spider gears Another word, turn wheel 2 times equal numbers of drive-shaft turns is the ratio.
10) If you want more accurate ratio’s number, turn dual 6 times and divide drive-shaft’s turn 3 time equal axle ratio.


For what it’s worth.

Sojourn for Christ, Jerry
