GY6 Transmission Cover Bolts (pair)

GY6 Transmission Cover Bolts for 125cc and 150cc Engines

These fasteners hold the lower edge of the transmission cover in place on GY6 125cc and 150cc engines. They play an important role in keeping the transmission system sealed and secure. If you're working through GY6 scooter parts and have noticed worn splines or grinding sounds, these bolts are worth checking. Swapping them out can help stop further transmission wear when the engine is under load.

When to Replace It

Consider replacing these bolts if you see wear signs such as slipping while riding or odd noises coming from the transmission. Those symptoms point to possible problems in the final drive system that should be looked at.
