Description

This Blue Line gearbox case gasket is a fresh start for a leak-free gearbox service on compatible GY6 125/150 and 139QMB-based 50/80cc scooters. Replace a damaged or torn gasket when opening the transmission case to help keep gear oil where it belongs and get your scooter ready for the next ride.

Features

Gearbox sealing: Helps restore the seal between matching transmission case mating surfaces
Universal application: Fits compatible GY6 125/150 and 139QMB-based scooter gearboxes with the same gasket outline, bolt holes and passage layout
Service-ready replacement: Ideal to have on hand before opening the gearbox for repair or maintenance
Color may vary: Supplied gasket color may differ from the product photos

For universal applications, compare the old gasket and case mating surfaces before ordering. The outline, mounting holes and passage openings must match. An engine code containing “QM” or “FM” alone does not establish compatibility. Clean the mating surfaces and follow the vehicle's service procedure during installation.
