Bafang Motor Servicing

 

We currently service the later model Bafang motors, common models being the Bafang M500 and M600 series

The Bafang motor is in general a good solid and reliable motor, with good sealing internally - although the external facing main crankshaft bearings, on both the left and right casing sides, commonly fail due to water ingress. Additionally, water (moisture) can be trapped and can pool around the external bearing pockets (that is, the external casing pockets for the two crankshaft bearings, left and right). The most common issue or problem reported by Bafang owners is the increase in the motor noise and the motor roughness... and this relates directly to the main crankshaft bearings that fail. There are other minor bearings that are checked and replaced if required. The gear assemblies and the gear teeth are cleaned of old grease and specialist internal motor gear grease is reapplied.
