Axle nut torque - M796 ABS w/ 46mm nut?

[Curmudgeon]

Will/can someone with a shop manual confirm that the factory torque figure is 120 Nm = ~ 88 ft. lbs.? I need a rear tire fitted and my local, very careful bike mechanic has the equipment and knowhow but not the skinny on my bike.

Have already been advised to lightly grease the nut prior to torquing. Will safety-wire the clip as my dealer already had. Any other tips?

Thanks!

I don't have a 796 manual at hand, but all of the recent stuff, S2R, S4R show 176 N-m.

A very thin coat of grease on the stub axle from threads to fillet, and same on the face of the wheel that touches the axle flange.

Not sure of the configuration of the 796 wheel in the area where the drive pegs go, some SSS wheels are idiot-resistant, others are not.

Get the pegs in the holes, or you can get a wheel like this :

Thanks for taking the trouble. I have only the parts book. Some stuff looks similar and other bits appear different. Good tip about the pins although the parts diagram shows no taper. The 796 book doesn't show this side of the rear wheel.

The principle is certainly the same. I do have snaps of an S2R rear wheel and the nut is a bit thinner on the 796.

That 120 Nm figure I got from Nathan at Duc Pond. Generally he's a very squared-away parts manager. He said that the 796/1100 axle is the same as 848 FWIW.

You could well be right but there is a big difference between 88 ft. lbs. and 130! Will wait for confirmation from someone with a new-style Monster manual. Worse case, I'll get the spec from Donnie Unger who can sometimes be hard to reach.

Thanks for the tip on the pins. Hope those are not an interference fit.  Ordered a Rosso II from Dennis Kirk this PM; even cheaper than eBay as they often are!

[Speeddog]

No, the pins aren't an interference fit.

The problem is that the wheel can go on without the pins in the holes, and torque down, but unless you look carefully when installing, it can be wrong, and it will get loose and fuxxor parts.

Worth double-checking the recommended torque, of course.

Unfortunately, I don't have a pic showing the wire clip in the correct way.
Don't put it on this way (it's backwards in the photo):

Thanks for the tip but I must be dull.  Is the clip flat on one side and rounded on the other? Not having it in my hand, I can't tell what's wrong with the orientation. What am I looking for?

Worst case, I can install mine in the same direction it came off I suppose...

[Speeddog]

Put the clip in so that starting from the end that goes into the hole in the axle, it winds around counterclockwise.

So, if the nut starts to loosen, it will try to force the clip into the groove, rather than sproinging it outward.

Hi, sorry for late reply, hope this sheds some light

Rear sprocket side wheel shaft retaining nut (LH) M33x1.5 156Nm                    * GREASE B
Rim side wheel shaft retaining nut (RH) M38x1.5               176Nm                    * GREASE B
*Grease B = Shell Retinax HDX2 or equivalent Molybdenum disulphide grease with high mechanical stress and temperature resistance

Carlos,

Thanks, I called back today and got 160 and 180 Nm respectively from another tech, so that tallies roughly with your info. No idea where 120 came from yesterday! 

Speeddog,

My axle has two holes on each end. Is there a tit on the end of that clip which goes into one of the holes? Hard to see without the thing in my hand and the parts book illustration is no help. As installed on my bike currently, the safety-wired ends are both above one of the holes, but a different one on each side.

Info is copy/paste from OEM manual . . .

Yes, the "hook" goes into the hole as shown in the pic above, for added safety, then wire

Pic of clip, in proper orientation.

Tit goes through the nut into the hole in the axle.

Torque the nut to spec, then attempt to insert the clip through the nut into the axle.
If neither hole is accessible, tighten a bit more until one of the holes is accessible.

[Curmudgeon]

Perfect! Thanks for the snap. All makes perfect sense with this picture "worth a thousand words"!

DarkMonster620 has it right.

156nm Chain side
176nm Wheel side

Thanks for the confirmation. No doubt you have the latest data in your new "office". 

Had a new Rosso II shipped to my mechanic which arrived today. Should get it swapped out on Monday as long as the weather gods cooperate. Hoping I like it as well as I did the OEM Rosso which came on the bike which is now down to the wear bar in the rear at 5,300 miles. The front has 2mm to the wear bar which I trust will get me to the 7,500 mile service!
