I have a BBS02 attached to the bottom bracket of my Trek Dual Sport and I can't seem to keep the motor tight against the frame. I have the Lekkie one nut and have tightened it by hand; then a few taps with a soft mallet. It loosens after a few rides. I don't want to apply so much force that I distort the BB. Any ideas on how to tighten?
Thanks!
The wrench included in the kts will never apply enough torque to keep the motors tight. I torque the nut to 80nms using a torque wrench and special socket for that nut. I also use orange threadlock to make sure it stays tight. I've never had one come loose.
