V2 Rear Axle Torque Spec

Hello,

I’m planning to adjust my chain, does anyone know what the torque spec is for the rear axle pinch bolts on a V2?
 
Very low. Do not overtighten or you will be spending some $$$ on an eccentric hub repair. And make sure you tighten them slowly in a 1-2-1-2-1-2 pattern (don't tighten one all the way and then the other all the way - instead alternate).

18.4 f-lbs or 25 nm

Thank you very much for the info, I really appreciate it.

Also note that there is no manual for the V2, so that number is what the original sheet (that someone posted) says from Ducati for V2 torque specs. The V4 had a service bulletin that lowered the spec to 20 nm. The older Ducatis were 30 nm.


Thanks for the response and a great info, that is very interesting.
So do you think I should use 25nm or go with the 20nm based on what the V4 update states?
 
I also read that KarlKani has 20nm listed in their response, so that’s the second time in this thread that the 20nm has come up.

I think the bolt sizes are different on the V4 and V2, but I'll have to measure mine when I service it next. I have been using 25 nm without an issue on my V2. The service bulletin basically says that some V4 hubs were "clicking" so they loosened the bolts, LOL. You could go with 20 nm and use an oil pin to mark it and see if they move after each ride. If they stay in place at 20 nm, then you are good. If they move a little, then you could tighten them down to 25. There isn't much difference between 20 and 25 nm, but for some parts, it could matter.

That sounds like a great idea. I definitely don’t want to over tighten them for sure. Although I have read 25nm used somewhere else, so the fact you brought it up is the second time I’ve heard that figure. Thanks again for the response.
