had this one out for some other work and had to reseal the cover anyways. so a quick pic if youve never seen inside one. splitter and range in the rear housing.

 

That's just half of it?

 

yes thats the main case, its the bulk of it but the rear housing contains the splitter and range

 

used to tear those apart and rebulid them.

 

Thats punk! Its only got two countershafts!

I wish I only had to work on Eatons. These new ES series are a pain to time!

 

I count my blessings we don't ever have to see them monster triple shaft Macks.

 

Yeah, you aint missed much! Its odd that anything in a main case tears up but I bet I average 3 or 4 synchronizers a month! Usually when something in a main case goes down it takes out enough stuff to justify a reman assembly!
