clutch drum grooving from c2 steels

[quadracer37]

i am refreshing my trans and found this. i cant imagine it is any good for quick engagement/disengagment of the c2 clutchs. all of the frictions are pretty well burnt, but suprisingly it never thru any codes before it was torn out.
anyone else had this problem?
whats the cause?



the bottom picture the grooves dont look horrible but you can most definitely feel all of them.

use to have this problem back when i raced quads on the oem clutch baskets and we ugraded to billet baskets...

I have the same thing. I always thought mine came from the partial lock-up during shifts I had on my tranny. Next time in, I am going to change out the carrier.

It's not a uncommon thing to see.

I don't think Hinson makes anything for the Allison lol

My dragbike clutch basket always looked like that. It is just from the clutch plates getting shocked real hard. They have a little play in them and over time this is the result

That and the kolene s are harder than the drum

Mine was like that after 35,000 hard miles with Kolene steels. Shouldnt be a problem anymore though

yeah, n thats to bad because i get a smokin deal from them

i have not see any billet housings to replace this so im assuming people are just replacing them when they become this worn out??

I just tore down a stock ally with the same groves. Where is a good place to get the replacement for that an the c-2 apply/clutch piston. My c-2 has stress fractures all through it.
