Standard Replacement Variator Nut for Piaggio 50cc 2T Scooters Variator nuts wear out over time, after many removals the thread stretches and wears down. Overtightening can also cause premature wear of the thread. Replacing the nut is the easiest way to make sure you keep the thread on your crank in good condition. Worn nuts can often cross thread on the crank and damage the crank beyond repair (new crank shafts aren’t cheap, nuts are!) Dimensions: 9.8mm depth / 20mm base OD / 15mm hex / 10mm ID / 1.25 Pitch.
