Fan impeller for 125–150 cc 4-stroke scooters. It is mounted on the shaft and blows air through the cylinder fins to cool the engine. Country of origin: China.
The impeller must be replaced if the blades are broken or cracked: the imbalance causes vibration and the engine overheats. Also check the fit and the mounting on the shaft. The impeller runs at high revs, so install only an intact part with no cracks.
What to consider when choosing:
- diameter
- fit on the shaft
- engine type
