I did a quick search on torque setting for rear sprocket nuts...nothing came up, I'm not a fan of the torque wrench, but knowing the damage loose sprocket nuts can cause to the swingarm, I'd better follow correct procedure, as a precaution I will also use loctite 243
any reply would be appreciated

The Genuine workshop manuals don't actually show any settings for this but with later models they start to show up for example an S4RS Rear sprocket nut ( M10x1.25) 48Nm with blue loctite , M50 Rear sprocket nut torque is 46 Nm with blue locktite.

The important thing is to use loctite to secure, With my old Carbed Monster I actually set it at 50Nm which still didn't feel tight but was what I was advised by other owners and to be honest never caused an issue.

The rear wheel nut guide on the 907ie in the manual is a flexible 68.7 to 73.6 Nm ????

Conversion guide here


Ft.Lbs to Nm x 1.355
Nm to Ft.Lbs x 0.737

thanks English I also had a good look on other sites and found a wide range between 35 and 93 N/M
then seen this...

...48 N/M+ blue loctite sounds good

We could do with something like that for our Paso models.......that is very useful good find.

i always do sprocket nuts to 45nm with blue loctite, but the most important part is to make sure the cush drive pins are tight in the carrier. on the early bikes they turn the same way as the nuts, if that makes sense. and i think that's why so many came loose back in the day.

i put an 8mm hex piece in the vise, then sit the carrier on that, inside whichever pin corresponds to the nut you're going to tighten. i then use a tyre lever on another pair of pins to rotate the carrier to check the pin is tight. from memory on late ones you go against the nut tightening, so you'd move the tyre lever anti clockwise. but on the early ones (generally 14mm nuts) you turn the carrier clockwise to make sure the pin is tight, then tighten the nut in the same direction.

if the pin is not tightened on its own when the nut is loose, even if it is held so it can't move while the nut is tightened, it may not be tight in the carrier and then the pin can move, the nut loosen and you get the beloved swingarm groove.

i tend to rotate the carrier both ways on the first pin just to confirm which way is tight. one direction it will stop, the other it will keep going.

thanks Brad, that's a good idea to check the pins as well, I was also impressed on how good loctite 243 is, check the video on this link where they test various mechanical thread locking system, loctite wins hands down.
