Starter Drive Gear for Scooters & Mopeds

Starter Drive Gear for 50cc 2-Stroke Minarelli Engines

This starter drive gear is made for 50cc 2-stroke Minarelli 1PE40QMB Jog engines. It plays a central role in how the engine gets started, so it needs to work dependably. It belongs to the range of scooter starters and relays and can be swapped out without much hassle, which suits anyone handling their own repairs. Fitting a new one can bring back the starting performance of your scooter and help the ride feel smooth again.

Build and Layout

The gear has two sides of different sizes. The small-tooth side measures 40mm across, while the large-tooth side measures 34mm. A needle bearing sits inside to allow it to turn smoothly. Thickness differs between the two sides: 7mm on the small-tooth side and 5mm on the large-tooth side, which helps it sit securely and operate correctly.

Operation and Upkeep

The gear has 47 small teeth and 20 large teeth, allowing it to mesh properly during start-up. Keep an eye on its condition, since wear can make starting less reliable. If your scooter starts with difficulty, replacing this gear may restore proper operation.
