I am sure someone here did this before. About a month ago a low slided my S2R1K. The clutch cover bent. When the cover got pushed in the springs holding the pressure plate snapped off. I bought a new Speedy Moto pressure plate with springs and a new OEM clutch hub from the dealer.

I took off the pressure plate. Since I do not have an impact wrench I used a breaker bar. I really did not go crazy on it but I cant take off the nut that is holding the clutch hub. (The gear thing which has the fingest to attach the springs behind the pressure plate).

I had a friend of mine sit on the bike and hold both breaks down so the bike wont move, but all that happens is the chain getting more tension sp? Am I messing anything else internally when attempting to take this nut off?

Is it possible to take this nut off without any specialty tools or taking it to the dealer?

Any advice would be appreciated.

Thanks

Many ducati owners have made their own tools from a few old clutch plates welded together with a handle welded on.  That holds the hub in place while you work on it with your breaker bar.

Something like this:

As an alternative to the tool, put the bike in 6th and lean on that breaker bar.
Make *sure* the socket is mating completely with the nut.

Thanks for the options. I will try the 6th gear and give it a go. I would make that tool but dont have any friction plates.

I think when I did mine I only made it up to 4th and I sat on the bike w/ the rear brake on and my 180# dad leaned on the breaker w/ all his weight.  Needless to say, make sure the guy holding the bike has a good stance once that nut gives and your buddy suddenly falls over and you are suddenly resisting a force that is no longer there.

when you get to thinking about buying one of those tools for 75$, consider this.  It takes about an hour to swap out your clutch plates, and 150$ for new ones.  Just do that, and you get a dirt free new clutch, AND the parts required for the tool!!  Then, while the old ones are out, simply make your tool, do the thing, and slap in the new plates on reassembly!

you can buy the tool from several places too.
i've used the one from desmotimes.com
(try speeddogs free method first  )

+1, I made my tool as well...!!

Interestingly, this same topic came up recently on another, non-Ducati forum.  It was pointed out that with power tools it isn't too hard to get the bolt off without a clutch hub tool, but it's much harder to properly torque the nut without the tool.

Any comments on this from the 6th gear proponents?

It can be torqued back on with the 6th gear method, same situation, it's a *lot* easier with a helper.

I do it with the bike on a lift, so the front wheel's clamped and the bike can't roll away.
Not something the average DIY'er has...

I'm a butcher, I stick it in sixth and use a bit of soft 2x4 across the swingarm to jam a spoke.

I wouldn't recommend my method to anyone else, but it works fine for me :-)

That sounds like something that I would do.  It's amazing how useful a tool a two foot length of 2x4 can be.

You can even use a shop rag or the like to pad the 2x4 so it doesn't mar the paint.

Sure.......ride the bike pretty damn hard for about 32,000 miles and it will work itself loose all by itself. You can then tighten it while in a McDonald's parking lot so you can ride the 150+ miles back home....





Sorry, but I couldn't resist. 

When reassembling the clutch, clean and dry the output shaft and hub nut really well and use blue locktite on it before tightening it. Ideally, you'll want to use a torque wrench when reinstalling it, but I know some guys who use blue locktite and over-torque the hub nut to prevent it from coming off. I have no idea of the setting or size of the wrench, but one guy told me to use an impact wrench and torque the cr@p out of the nut.   

I didn't have time to try anything since I posted this. But thank you all for the input. Hopefully I will have some time this weekend to play around with it.
