This cross type flywheel puller suits 50cc 4-stroke QMB139 engines, along with 125cc and 150cc 4-stroke GY6 engines, including GY6B versions. When you need to reach the flywheel for servicing or repair on a scooter or moped, this tool gives you access. It also relates to scooter stators & regulators, which play a role in checking battery charging and the electrical system. It comes in several sizes, so it can be used with a range of models.

What This Part Does

This puller lets you take off the flywheel so you can check or swap out parts such as the stator and regulator/rectifier. Symptoms like a flat battery, dim lighting, or a burning odor may point to a fault in these components, so the tool is useful for diagnosing and repairing them.
