I'm doing a front tire change on my 2016 Panigale and don't have access to the service manual.

Can someone provide the torque values called for on the:

Front Axle Nut
Lower fork axle clamp pinch bolts
Brembo Brake Caliper Bolts

Thanks!
 
I think the standard fork axle clamp bolts are 12 or 14 Nm. The Ohlins is 19 Nm

Thanks, I have the standard base model forks, Marzocchi I think, they're only 5mm pinch bolts, very delicate and I snapped one off in the lower fork leg earlier today at a very low torque setting. I had my torque wrench set to 10 ft-lbs or 13.5 Nm and it never broke over, just kept turning in without building resistance. It turns out all four pinch bolts were heavily greased and that threw the torque readings off apparently. The front wheel has never been off this bike, 2016 with only 1500 miles when I bought it, so they must have greased those bolts at the factory. I'm speculating here. Anyway, the three remaining bolts have stretched threads and all will have to be replaced. My concern now is the threads in the lower fork legs, it's aluminum I believe. I didn't pull any aluminum out with bolts so I may be OK and just need four new bolts and EZOUT the broken one. What started out as a quick front tire change is turning into a big headache now.
 
Worse case drill the holes, even preemptively, and use a heli-coil. The repair will be stronger than the original threads.

I never saw a 1299 shop manual online, just the 1199, but I really never went looking.

There isn't a M5 bolt that is torqued higher than 6 Nm though.

BP you are correct, a standardized torque chart calls for 2.7 Nm to 10.4 Nm depending on the specific bolt grade with dry threads.

My guess is 5 to 6 Nm max for these bolts in aluminum but have no idea what the manual actually calls for.

I tried to torque them to 13 Nm but they were literally saturated with grease, one broke off, the other three have stretched threads, so I way over torqued them.

My bad, I am super anal about front end parts coming loose and should have known something was wrong when they wouldn't build torque, just keep turning with little resistance, blame the grease there.

The only good news, if you can call it that, is I found no aluminum on the bolt threads when I removed them so I might have gotten lucky and not pulled the threads out of the fork lower.
 
Broken bolt came out easily with a reverse rotation (CCW) drill bit. No aluminum found on any of the threads, so I think I'm going to be OK with a set of four new M5x.8x25 bolts.

Still don't know the required torque value for the pinch bolts per the manual though, does anyone know?
 
My 959 Service Manual General Torque Value Table calls for anywhere from 3 to 7 Nm for M5 bolts depending upon the application, a good guess would be 5-6 NM with dry threads but mine are still pretty well greased up...
 
I was checking around and someone on another Ducati forum said the base model gets 7 ft-lbs on the base model 1299 Base Model pinch bolts, sounds like a lot for a 5mm bolt. Going to pickup 4 new bolts in the morning and try this again. BTW, I found an old thread and it sounds like I'm not the first to do this on a 1299 base model...

Are you sure? my 1299 manual shows the bottom triple pinch bolts 8nm and the top triples and clip ons 22nm

Thank you... for some reason the standard 1299 manual isnt available online, or i just couldnt find one. Yes i confirmed 8nm for pinch bolts on standard forks. 19nm is for the ohlins.

I'm so confused, is it 8 Nm or 7 ft-lbs for base model pinch bolts, can't seem to find any agreement? Also lubed threads require 30-50% less torque depending on type of thread lube.
 
With a value as low as 6-8 Nm, it's more of a do not exceed rather than a minimum. Hand tighten with an Allen key or a 1/4" ratchet. The axle clamp bolts don't need a lot of torque for sure.

With Ohlins forks, the torque values are laser etched onto the bottoms.
 
Here are the specs for the 1199. Quos a very low value (6Nm)

Thank you KA77, that 6 NM sounds correct and what I will use as a Max value. Picking up a new set of the clamp bolts this morning, will assemble with dry threads but there is still grease in the fork clamp assembly internal threads, will try brake cleaning spray solvent to get that out of there.
 
Turns out these are not M5 x .8 x 25 bolts as I originally thought but rather M6 x 1.0 x 25, I had an original matched at ACE hardware this morning in a grade 12.9 fastener which is a bit overkill for this application but now I'm speculating the torque is going to be higher than 6 NM for an M6 size bolt, see table below where even a low Grade 8.8 M6 is torqued to 11.8 Nm.

KA77, I didn't see those pinch bolts in the 1199 spec sheet or maybe I just missed it, was that 6Nm torque callout for an M6 pinch bolt?

I ended up cleaning all the old grease out of the aluminum threads with brake cleaner as the new M6x1.0 bolts were not creating any torque, same as before. Whatever that stuff was, it was really slick.

I took them up to 5NM and called it a day, I didn't want to press my luck by over torquing again and run the risk of pulling the threads out.

Took the bike for a ride earlier this evening and everything was fine.
 
There it is, 6NM and it does callout a special grease on the threads, Shell Retinax HDX2 grease is Molybdenum Sulfide based, that stuff is super slippery!
