    Chain adjustment won't stay put

    Mine is a 2006 model TW. When I adjust my chain to where it is correct according the the service manual, both sides are in #5 notch. No matter how tight I tighten the axle bolt/nut, when I take it for a ride, the chain side adjuster works it's way to the fully loose position. The right side stays put in the #5 notch. It's the left side that won't stay put. What am I doing wrong?

    Hi Ron,

    This is a new one to me! Is the axle on the chain side moving forward also, or is it just the snail adjuster that is slipping under the axle head?

    Hi Ron,

    I understand that the snail adjuster is rotating around the axle. I am trying to understand whether the axle is actually moving also.

    When the adjuster slips, does the chain also become looser?

    The snail adjusted ends up at the fully loose position and the axle moves forward so the chain is too loose.

    I am a little worried that when someone figures this out I might have egg on my face.

    The bed is calling. I'll check in tomorrow.

    Thanks

    When you make the adjustment, how much slack are you leaving in the chain? Are you using a torque wrench to tighten the axle?

    Are you slamming the rear wheel forward so the notches are seated in the tab before you tighten the axle bolt? It seems unlikely that the axle will first loosen enough to allow the wheel to go back first, allow the snail to disengage and then move forward to allow the chain to loosen.

    Thanks for the reply

    I tighten the chain to where I can lift it an inch with my finger pressing upward half way between the front and back sprockets. I have not been using a torque wrench to tighten the axle nut. How many footpounds should it be? I have been tightening it as tight as I dare without stripping the threads or breaking something.
