Removed the primary drive and found that the clutch hub had no teeth left. All of them have been ground off. In the pic of the hub you can see where the splines used to be.
 
What I think happened is the clip failed and allowed the hub to move into the primary (it could not move out as the nut was holding it there) and this in and outward movement slowly ate away ate the teeth.

Here's a pic of the shaft with what's left a the clutch hub teeth remaining in the splines.
You can also see the ground up aluminum in the bottom of the primary.

Sorry to see all that Ernie.  It'll end up being a pretty expensive three dollar clip.  No unusal noises in the little while beforhand?

Yep, a new clutch pack and inner hub, about $350. The real odd thing is that the clip that failed is not a replacable part. It comes preassemble on the new hub.

Hard to tell from the photo.  The shaft is ok?

Seems to be. It was getting late but i wanted to get it apart to see what happened. I will get it all cleaned up tomorrow and verify. In all likelihood it will be fine. One benefit of having an aluminum hub I will be pulling the stator rotor apart tomorrow as well and make sure no aluminum did damage to the stator or magnets....

That's good news.  As long as no mass of debris collected in one spot and chunked something it's worth being optimistic.

General curiousity.  Separate from the physical damage that came from it coming apart.  Would be interesting to know how the discs themselves were looking with 30-35k miles on them.

That is odd. HD-dude have you ever seen anything like this before? Good thing for the alum hub.

No noises beforehand, and no noises when it let go.  About 10-20 miles prior to it letting go, the clutch felt weird and it was hard to shift so I headed home.  Obviously didn't make it

Glad you all survived.  Another bad place is stopping under an overpass to put on rain gear, very unsafe.

Ernie,
Thanks for the words of wisdom, and glad to hear that no one was harmed during this incident. Sorry to hear about your mechanical problems, that's a bummer. The experience you had with the dealer is commendable glad to hear that there are still some that understand the meaning of "Brotherhood".

I'm sure Jim will have you up and running in no time flat.

 
Ride Safe,

d00d,

I know what you mean.  It's nice to get something other than "shut up and give me your money" for a change.  I know where I'll be shopping in the future instead of the dealers that I've been going to.

With Jim there's never a worry.  He came and got the bike yesterday, and he was as curious as I was to find out what happened.  So far it's a clutch and hub if nothing else got ruined like the shaft and/or stator.  It'll get the upgraded Screamin Eagle clutch with 9 plates instead of 8...

Good to hear that the bike and all the peeps will be fine.

I broke down once on an interstate bridge with no shoulder at night with no power.

It was eerie to hear the screeching tires as cars came up on me and then dove in the left lane as the went by.  The 20 minutes for the tow truck to get there was the worst 20 minutes I can remember.  We nearly got nailed multiple times waiting and when loading on the tow truck.

Hope Jim's got you going soon.

I've seen clutches scatter before (mostly due to burn outs) but not one strip out like this.

[mr_magoo]

Ernie must have way to much power.  That is interesting how it stripped the hub.
