Hm 821 Sp Rear Wheel Removal And Torque Values

  1. This should be straight forward but...in the absence of a manual I would like to confirm the process and make sure I've got all the right values for putting it all back together again.

    Just ordered the 46 and 41mm sockets required and looking at the rear wheel, (borrowing a bar and TQ wrench) it seems that only the 46mm nut will be removed and the wheel should come right off...this is what I used to do on the 748, there should be no need to touch the sprocket-side 41mm? Unless there is some hidden mechanical wizardry going on that I can't fathom.

    Do we know for sure what the 46mm nut torque setting is? 176Nm? searches of various forums throw up a range of numbers, some of which appear to be related to the air-cooled models. Just for completeness it would also be nice to know what the torque values for the 41mm nut and the pinch bolts for chain adjustment are.

    I already adjusted the chain and torqued up to 38-40Nm, values from ducati.ms, but the dealer reckoned that was too high, but didn't tell me what they thought it should be, I think the old model was a lesser value?

    Of course it would be nice to have a proper workshop manual, but such a thing does not seem to exist outside of the dealer garage. I used to have a Haynes for the 748 which was very useful.
     
  2. After some internet digging found these...2 values 176Nm and 230Nm...so which one do we think is correct?

    not sure if the wheel shaft fastener referred to above is the actual wheel nut...

  3. as a rule of thumb, on all the single swingers' the later 55mm nuts are 230Nm whilst the earlier 46mm nuts are 176Nm. that's the 55mm nut in the picture btw ;)
     
  4. thanks for that Nelly

    the pic is from the 2014 HM SP workshop manual (found online), so I'm guessing it must be a "stock" picture... my bike definitely has a 46mm nut
     
  5. I have a monster 821 - 2014 and also need to know the rear wheel torque!!! Anyone knows it? It uses the 36mm BI HEX 12 POINTS
