Gasket Crank Case for CSC Go., GY6 50cc (139QMB) Scooters

Right-Side Crank Case Gasket for CSC Go and Comparable Scooters

This gasket for the right-side crank case is made to swap in for the factory piece on CSC Go scooters, as well as on models such as the Genuine Bella Classic 50, Nitro Sport 50, and Pug 50. Its job is to seal the crank case so oil stays contained and the engine runs as it should. It is one of the essential GY6 50cc scooter parts worth keeping on hand during routine upkeep.

Compatibility Information

This gasket works with a range of 50cc and 80cc engines built on the 139QMB platform. It is designed for engine codes such as 139QMA, 139QMB, 1P39QMA-2, 1P39QMB, and YN139QMB, among others. When your engine code contains "QM" or "FM," this part will fit your vehicle.

Swap out the crank case gasket when oil begins to leak or when the engine loses power. Checking it regularly can stop small problems from becoming larger repairs. Installing a fresh gasket restores a proper seal and keeps the engine working correctly.
