M22 Flat Washer for Scooters & Mopeds

M22 Flat Washer for 150cc and 125cc GY6 Engines

This M22 flat washer secures the starter clutch to the crankshaft in certain GY6 engines. It is designed for 150cc and 125cc 4-stroke QMI152/157 and QMJ152 engines, plus 150cc GY6B engines. Among the scooter bolts, screws & hardware available, it plays a key role in keeping the assembly secure and avoiding problems during repairs.

Function of This Part

The washer works as a spacer and spreads the clamping force of the bolt across a wider area. That even distribution helps protect the crankshaft assembly. It is commonly swapped out during routine maintenance or whenever the starter clutch is serviced, helping the engine run as it should.
