250 Nm???!!! What is the perceived wisdom in undoing the above and then re-torqueing it up to the correct torque? Even my heavy duty torque wrench doesn't go far enough...
No easy way....bigger torque wrench and the correct holding tool. Some of the torque settings in the newer motors are massive.
don't forget the Loctite with both threads (nut and shaft) as dry as possible. I use 638 at the moment but several specs are suitable.
Have decided to go with 638 because I can't get the other stuff Have ordered the biggest torque wrench I could find (!) – Already have the holding tool – in terms of removing this nut do you use a breaker bar or is it easier and safer to use an electric impact socket? Finally what size is the allen? Thanks
Clarke CEW 10000 every time :- Clarke CEW1000 240V ½" Electric Impact Wrench with 4 Sockets - Power Tools, Impact Drivers & Wrenches, Impact Wrenches - Electric I would never have believed it possible that 13 amps could do the job but as of 4 years ago I am a converted man and would never be without one - good quality at an extraordinary price considering. I hate the term but literally 'plug and play'. Can be awkward getting the socket on and off the crude 'C' clip snubber but apart from that 10/10 EDIT You don't even need to use a restraining tool when undoing such is the instant/huge torque delivered.
They are as good as peeps say. Bought one for my 1098s a few weeks ago, back wheel nut undone in under a second. Chris is correct when he says you don't even need to restrain when using it. Just be very prepared for the amount of torque, hold the drill with both hands (you don't want a broken wrist )
Used a 1 euro cent to hold the gears/clutch on my Kid's 60cc off-roader but I wouldn't try it on a Ducati (and the coin wouldn't go in a vending machine afterwards!). I have the big clutch holding tool but bought one of those plastic bolt-on holders that Machine Mart sell as I thought it would be easier to use without an assistant. Damn thing snapped like a breadstick before I'd reached the required torque...
