OEM Surron Motor Bolt Washers-Surron Light Bee

Square washers for the motor tensioner bolts on the Surron Light Bee X, sold as a pair. They are an upgraded part that fits in place of the OEM washer.

The washer spreads the clamp load where the tensioner bolt holds the motor position. A dished or deformed washer lets the motor creep under load, so belt tension that was right this morning is slack by the afternoon and the belt starts skipping teeth on takeoff.
