Damn, I should have taken a pic, as I normally do.
Someone please correct me if I've got it wrong. If I remember correctly, the thicker side goes to the fork and the thinner one, to the wheel.

I also like to put it back the way it was but one race mechanic (Guy Martin from MBP) once told me that it makes no difference. He's also an aircraft encgine mechanic.

I hope someone can shed more light on this.

you are not joking had an air gun on mine for about 2 mins before it gave in

My air gun didn't win this battle. The "Persuador" did (4-foot square tube).

It was so tight that the wheel bent the bar designed to hold the spoke on the rear stand. I've used it for six years with two previous Ducatis and it never happened. So I asked the little woman to sit on the captain's seat and hold down the rear anchor. I should have filmed it, the four-foot bar was arced for quite a while when, finally, the nut started to turn... very slowly.
 
so does anyone have the official torque settings: ?

Front settings are guesstimates:
-front axle 63nm - 46.4lbs
-front pinch bolts 19nm - 14lbs (i read someone snapped one with 15nm?)
-front caliper bolts 45nm - 33.2lbs


Rear is correct:
-rear wheel nut = 230nm - 169lbs
 
My local dealer tech told me 16 Nm on the pinch bolts and they STILL feel like they're stretching. I'm convinced they're damned poor material and that 16 Nm is still too much. The other numbers posted by RD16RR are what I've been using. I bought a large torque wrench a couple of years ago just for tightening rear wheel and hub nuts (and for the sprocket retaining nuts used on some models...which are also hellish tight).

Rear hub pinch bolts I've been tightening to 33 Nm, as specified in the 1098 manual. 1-2-1 with greased thread surfaces.

...aren't there only 2 rear hub pinch bolts ?
 
RD16RR said:
...yes, but for 2 bolts, a 3 sequence procedure ? -- you do bolt #1, two times ?

Yes. These are pinch bolts. Tightening the second bolt will have the effect of reducing torque on the first one as the second bolt is torqued.

I just removed my front wheel yesterday. The larger spacer was on the left side (when sitting on bike) and the smaller spacer on the right side. The larger end of the axle (with the notches) was on the right side.
 
What's the latest thinking on the torque for the front pinch bolts? I'm told they're extremely fragile and that I should only tighten to 10NM. I trust the mechanic who told me this, but was wondering if anyone knows what the manual says (I understand that Ducati revised the manual to decrease the torque).
 
I saw this thread was just revived and the first thing that struck me was that a user posted the pinch bolts should be 45ish foot pounds. This is WAY over what the service manual says.

The pinch bolts aren't fragile, the swing arm is. There isn't a lot of material around that area. A crack because of over tightening...that's expensive.

The service manual lists 25 NM +/- 5% which is 18.4 foot pounds, +/- 5%.

IMO, snug them up and mark with a paint marker. Don't replace a swing arm because you went full ham with the bolts.

Rear nut, 150 ft lbs is the max of my torque wrench. I hit that and give it a slight tug past. No issues to speak of.

Search "torques chart" my thread comes up with the book chassis torques.
 
I've got this but it's too big to upload (1.44 MB). If anyone can tell me how to do it I will gladly share it :D

I think this is too much torque. Max is supposed to be 230nm or 169.63 ft/lbs., which everyone agrees is too much. Why would you do even more than that?
 
Had my rear tire replaced and asked the guy if he had done the rear nut to 230nm. He said that was way too much and I'd have problems getting it off. Was a bit paranoid riding away and then read this thread, I guess he was right.
