My clutch went south on the 440ex and I took her apart and also found a cracked and groved out inner hub. No one around here (honda dealers, and local shops) have seen one get messed up. Its not expensive, but I am curious if anybody has seen this before, and in particular, if anybody knows a cause.
thanks in advance

 

Sounds like it got used a bunch...possible hard launching going on with paddles on the machine?

 

Used bunch of what?
Yes I had paddles and I don't know about a hard launch, aren't they all?....lol

 

ive seen it sandneck. once on our duner and once on a buddies 350

 

Beech,
Do you agree with what Jay said? I think he meant a used bunch of plates, but not sure.
I am just trying to figure out if it was an installation thing, a heat thing, a power thing, or just a accident?
Any Ideas?, the Billet crap is super spendy.

 

sh*t happens. Do i agree? no. Its just from wear and tear, stuff like that will happen from time to time. Its not because you had paddles or because you were wearing nike's instead of Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word 's. More or less just an accident. be happy you caught it before it really came apart on you

 

Dosen't Jenna Jamison wear Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word s?

Thats what I thought. Since no body has seen one around here, I figured it was a fluke accident thing. Yeah I am glad, I woudl hate to see what would happen if it grenaded in there.
Thanks for your opinion....

 

jenna wears what i tell her to wear damnit. lol dont i wish.

ive seen them come apart and lock themselves up betweent he clutch basket and bend cranks.

 

I've seen one 400ex clutch frag also. Clutch parts all over inside the engine, required complete teardown to clean out the pieces. Even broke the steel primary gear on the clutch basket. I couldn't say for sure what part fragged first, but what was left of the plates didn't look burnt or scored. No other engine damage was done, but had the potential for all kinds of ugly. The machine had quite a bit of use and was in fair stock condition. The owner didn't know what he might have done to make it happen, and the inside of the engine was real clean like frequent oil changes were done. No clear cause for it to happen, but it probably started out as a crack (like yours sandneck), and just got to a point and gave out. Like Beech said, lucky you found it when you did.

 

Thanks everybody, beech, dzzy, I appreciate it. I feel better now.
