Help! I broke my clutch drum!

I feel STUPID! Just picked the bike up from the shop for the fuel mixture issue. In the mean time I had the clutch cover painted at a local body shop, when leaving in a hurry, I couldn't find my hex key to replace the cover. I pulled out of the shop, while at a red light, I moved forward slowly, my pants got caught in the clutch, broke the spring, retainer and pin off at the drum. Broke off the post to the drum. Bike would not go into gear at first, then only 1-3 at random, also the bike tries to lurch forward, I can only hold it back with the brakes. Where can I find the part I need, and how much is this going to cost me? I'm doing this myself. I can't afford to keep taking this to the shop. I feel like a BIG IDIOT!. I talked with a buddy who's a Ducati mechanic, he said it should be a simple fix, the damage minimal. I can't believe a pair of $100 Guess jeans could break molded metal.

Sorry to hear about your mishap.

If you have the tools, its a pretty easy fix...you can swap in a new clutch hub within an hour.   :)

Thanks for the quick reply. I have a few questions:

1. What tools will I need for the job? Clutch basket holding tool?
2. What are the chances I damaged anything else, what should I look for while I have it apart, besides any apparent wear?
3. I'm thinking of going with a slipper clutch. I've heard from I may lose performance.

Again, thank you for taking the time to help. It's just been an ordeal with this bike.

I wonder if this will work?

Quick 'fix', remove the spring and retainer opposite to the broken one.
4mm allen wrench is all that's required.
Ride.  :)

To replace the hub, you need a big socket and an impact gun.
I *think* the socket is a 32mm, not sure though, I just grab the one that fits out of my toolbox...

Wow, that sucks. I ride with no clutch cover, occasionally ride with jeans, and have never come close to catching my pants on it...

Quick fix as in? To get it home? Left it at the shop. I just can't see paying them when I can do this myself.

Absolutely.  ;)

Some folks even remove 2 springs just to ease the lever pull.

Just remove the opposite spring and try it out.  You *might* like it better that way.

So could be a permanent/temp fix till I decide to replace with a slipper/lightened clutch assembly?  Would a pressure plate stabilizer help?

Yep.

IMO, those are just pure functionless bling.

One might keep your pants from snagging again, so I suppose some functionality....

Easiest fix is Speeddog's way.  And then put the clutch cover back on!

Dammit boys, we have a winner! Thank y'all so much. My ego was bruised, as it should be. My weekend trip to Gatlinburg was ruined cause I thought I'd surely torn the hell out of the bike. Now if I can find these Guess jeans again.  ;)

In case you're wondering what's going on, the broken post is throwing off the balance of the springs so when you pull your clutch lever it tries to push out crooked and that's why it's not fully disengaging. Removing the opposite spring alleviates this problem.

The real fix to get it back to the way it was is to buy a new clutch hub. Funny that you should have this happen. I know it happens but I hadn't seen a thread about it on the board in a while but then He Man just broke his recently too. Check out this thread for the replacement clutch hub stuff. http://ducatimonsterforum.org/index.php?topic=22736.0

Thanks for that, I'm learning piece by piece about this bike. I chose a Duc because I wanted to run in a different pack, I love naked bikes, and I just fell in love with it.

No problem, I know not everyone is the mechanical type and we don't always understand the solutions posted here and just take them at face value as the fix. Good on you for wanting to do it yourself. I updated my post with a link to another thread that has clutch hub info if you want to actually fix it. At least you didn't have the post break off while riding like he did.
