Engine lock?

[ahdoman]

I need to lock the engine to do some service work (clutch replace, remove front sprocket). Is there a bolt on the case that will lock the engine at TDC?

No. I can't think of any modern engine that would have such a thing. If you are going to work on the Ducati's internals, you should probably invest in a workshop manual first.

Only option similar to what you want would be a camshaft locking tool. Locks the camshafts when doing a belt change.

Actually there's a couple of modern bikes that I've worked on that have an insert point to lock the crank. There's usually a bolt with a spacer on it, you remove the bolt, take the spacer out, put the bolt back in and as long as the crank is at TDC it will lock the crank.

Get a large friend to sit on the bike with it in gear and stand on the brake pedal.
When I changed my front sprocket I put a  locked the rear wheel with a board between the swing arm and the wheel spokes.

I've found standing on the rear brake pedal is enough to stop the chain rotating while the front sprocket is taken off. I can do it on my own but I need a long extension on the socket. I'm sure there's a picture of it somewhere on here.
Don't know about the clutch though. I thought they lasted forever.

Won't the old trick of jamming a large screwdriver between the chain and back sprocket do the job? Remove the chain only after you loosen the front sprocket. I've always used that method with success on my previous bike's. Clutches too. Alternatively, put it in 1st.
