Hi, Can anyone tell me the correct tightening torque for the large rear nut retaining the sprocket on a monster 1200? (On the left hand side when sitting on the bike). I have conflicting info so thought I would check here. Thanks in advance
Hi, thanks for coming back to my question. I got that from a copy of the electronic workshop manual. Contacted the dealer who advised 186 Nm hence my question. It is a 1200 monster.
186Nm enduro rear wheel nut for normal swing arm, 230Nm for multistrada single swing-arm. Monster 1200 workshop manual link
Thanks for the link Gunz, I am still a little unsure the section on the rear sprocket carrier retaining nut (2) in the first screen shot below, points you to the section on fitting the rear wheel (second screen shot) which references 230Nm for the retaining nut. The nut (2) retaining the sprocket carrier on the other end of the axle is the same set up as that used to retain the wheel so it seems a logical it would be the same but there is a big difference between 186 mm suggested by the dealer and 230 mm from the manual and I don’t want damage anything by over tightening Cheers b
It is 230Nm on both sides. If holes not aligned at 230Nm you should never loosen to align them. Always tighten more to align the holes.
Here are my rear wheel nut 176Nm & rear sprocket nut 156Nm torque values from my Hyper manual. Wheel nut clearly higher torque than sprocket nut, so I'd be surprised if your 230/186Nm (for the wheel/sprocket respectively) are wrong. Unfortunately I can't remember the source for this electronic manual, but I trust these torque figures.
The reason for that is your sprocket side nut is M33 and is smaller than the wheel nut (M38) hence the torque value is different. For M1200 both nuts are M48 which is a lot bigger than hyper and same size on both side. By the way 186Nm is the exact torque value for the front sprocket nut on M1200. That might be a misunderstanding between front and rear sprocket.
That’s good. Where’s the chart from out of interest and what kind of grease is grease B? Lithium I presume?
Thanks for correcting me and displaying the source. I know I have the 'small' rear hub but clearly was ignorant of the 1200 chain-side thread size!
