I just confirmed it does unscrew. Turn knob clockwise and trip odometer resets. Turn counterclockwise and knob unscrews. Maybe your shaft on trip odometer is broken. Does it reset when turned clockwise? Oh and BTW welcome aboard
Hello, Thanks for checking on it.. Yes, it does reset when I turn it clockwise. It's just hard
to get in between the plastic and the knob to get ahold of the shaft with a thin pair of needle nose pliers to turn it counter clockwise to take off.. But I will go buy a "thin" pair of pliers and try to get it off..
Thanks for your help!
