0007 Posted July 22, 2012 Report Share Posted July 22, 2012 " it should not matter how tight you do up the wheel nuts as this will not load the bearings " Actually you would be quite surprised how much distortion there is when a bolt is tightened, anyone who has tried to unscrew a fork cab before loosening the triple clamp will attest to this, it won't even budge, and that's a hard steel tube squeezed by a couple of 6mm bolts the only reason a bolt will tighten is because the threads stretch and lock into the nut, etc etc So yes the spacer will compress if over torqued and side load the bearing Quote Link to comment Share on other sites More sharing options...
pindie Posted July 23, 2012 Report Share Posted July 23, 2012 (edited) This means more torque as a compression force can be applied to the threads of the axle than the alloy spacer can cope with. The hard steel races are forced hard against the soft alloy spacer in the hub and will squash it longitudinally. Bottom line - don't over tighten your axle nut!

dadof2 Posted July 23, 2012 Report Share Posted July 23, 2012 Totally agree with paul w. I have seem quite a few spacers shorter than they should be. They are too soft and have too little diameter to properly support the inner bearing race. Cheers Quote Link to comment Share on other sites More sharing options...
razorback Posted July 23, 2012 Report Share Posted July 23, 2012 This is why we have torque specs and torque wenches. I used to hear the saying "tighten it as tight as it will go then one more round". That was my Dads philosophy and he broke a lot of bolts.

It's the same at the front axle, which is usually overtightened as the rider does not realize the axle pinch bolts secure the axle, not how tight it's screwed in.

pindie Posted July 23, 2012 Report Share Posted July 23, 2012 Always rub the threads with a dab of coppa slip also. Torque is king - get a measure for it! 1 Quote Link to comment Share on other sites More sharing options...
