Rear wheel lug nuts
« on: November 23, 2015, 11:36:10 AM »
One of the worst, most unnerving feelings in the world is the vague, stomach swirling feeling of a loose rear wheel while going down the road.

I've had this happen to me several times over the years; I usually take the rear wheel off for tire replacement.  I had assumed that hand tight with the lug nut wrench included in the tool kit was sufficient, but recently I've come to the conclusion that I either need to replace the washers and nuts, or use an extension on the wrench to get a tighter fit.  I suppose there's an actual torque measurement but never really considered it, perhaps that's foolish.

Thoughts?
'04 R1150 RT ~41000 miles
'86 R65 / '84 motor ~72000 miles. SS lines, Spiegler rotor, Progressive monoshock, Keihan silencers, a piece of Pichler fairing.
'76 CB400F ~26000 miles. non-runner!

This document gives you torque wrench values for just about anything you might need to do.

I thought the same and it does for most things but not for lug nuts on a monoshock.


Snowbum has some colorful guidance and the torque levels are high  -way above "hand tight" :

Mono-lever models (and Paralever, including R80ST, R80 G/S, R100GS, etc); rear wheel bolts:
                           Models have been made with both three and four bolts/nuts.  
                           NEVER EVER oil NOR antiseize these threads...NEVER!....just clean and dry
                           threads.   Use 63 foot-pounds for the R80ST, & a bit more, perhaps
                           75-77 for the G/S & 85+ models.  BUT: Pay attention to what your particular bike's
                           torque specifications are, some are higher.  USE BMW's Owner's Book values!!!
