clutch hub nut torque problem

Installing the new slipper clutch was simple. But,how the HELL do you hold everything stationary while torqueing the nut to 190nm??????

Stuck a dowel inbetween the rim and swingarm,dropped her into gear,then stepped on the rear brake. That did not work,snapped the dowel.

What's the secret???

You will need to get the clutch hub holding tool for that one I think. I did the same thing and got the tool. It worked great and I have the tool for any future
clutch work. I think I paid $100.00 for the one from MotoWheels. You can make one if you have a couple of old clutch plates, steel, and tack weld them together and then put a handle on it.
PS The dowel in the wheel spokes is a little scary I thought because I was afraid
of bending a spoke.

My 916 was a Horrid Blood Sucking Bitch.

$75 from Nichols, and an absolute necessity if you're going to remove or install the clutch hub nut.

Watch out on that torque value. 190 Nm is for a standard clutch, the Ducati Corse and early STM, TSS and others before 2002 are torqued to 140 Nm, with loctite 601 on the nut, and only the latest STM's "evolutzione" and Ducati Corse clutches used a recommended torque of 180 Nm. :twocents

Before you tighten the nut, check what the manufacturer of the clutch recommends.

Standard clutches have their nuts tweaked to 190 Nm, a bit of loctite, and all is peachy.

Have fun,
Peter

Thanks Layne. Here's a pic of the one I make ready for use. I stole this pic from Duc 748, I'm sure he won't mind, he's a good man. Oh yeah, mine holds the basket too.

Phil,

Does your clutch tool work with the 48 tooth baskets?

Thanks

If it's only holding the hub, then it should...

I haven't thought of how I'm going to hold the basket without a tool, but then again, it doesn't get the big torque either. Maybe a strap wrench would do it. I've got the 48T as well.

It doesn't but I have had a fair amount of interest for the 48 tooth so I might just do it. I have a 48 tooth basket I can use as a model. I test fit every tool to an OEM Ducati hub and basket before they get shipped.
