Bafang M400 reduction gear for replacement; the Bafang G330 motor steel cover is included.

The item includes motor gasket, reduction gear and gear cover/motor casing as shown in the picture.

For how to replace the reduction gear cover, please refer to the following vedio.

Bafang Max drive M400 /G330 barebone motor.

If your motor is "old age" and defective, you can buy a new barebone motor to replace it.

The are two protocols for Bafang G330/ M400 motor, UART and CAN, UART motor is with 3 pins speed sensor cable, and CAN motor is with 4 pins speed sensor cable, UART motor's display is round connector which CAN motor's display is triangle connector. If you don't know how to identify, please email us.   

How to check your max drive G330 motor is UART or CAN protocol? Check the original display connector, UART protocol is with round 5pin connector display which CAN protocol is with 5pin triangle connector display.

If you need complete set of Max drivec M400, please email us.

Bafang M400 G330 motor take apart:

Bafang M620 M600 M510 M500 M420 crank arm bolt/ screw;

Bafang Ultra  m620 G510 motor stator for repair;

Bafang ultra M620 motor windings for replacement.

If your Bafang M620/G510 motor gets error 08, it could be the stator or controller failure.

The M620 motor needs calibration after replacing the stator, UART motor use our special 961 display for the calibartion and CANbus M620 motor needs Bafang Besst tool for calibration.

For How to remove Bafang M620 stator, please check the following video:

Bafang Ultra M620/ G510 mounting bolts /nuts /washers, including chain wheel lock nut and the other bolts as shown in the picture.

If you need a special spanner for the chainwheel lock nut, please check from here: Bafang M620 chainwheel lock nut wrench 

Thumb throttle/accelerator for Bafang central driven motor kit bbs01, bbs02,  BBSHD, Ultra G510 M620, Max drive M400, M420, M500, M600 or M800 mid motors.

Note: This throttle also fit for Bafang Max Drive M400 G330 motor, but you need to change to a 1T4 EB-BUS, otherwise you cannot connect the throttle to your Max drive unit.

Bafang DP C010.CB display, the latest Bafang HMI, it supports Bafang Go+ 

Bafang DP C010.CN display, the latest Bafang HMI, it supports Bafang Go+, and it has navigation mapping function(when the user uses the HMI with BAFANG GO+. When the user starts navigation with the app, the navigation route will map to the HMI in real time. For detailed operation, see BAFANG GO+ App Operation Manual.)

The display has 6 languages for option: English, German, Dutch, French, Italian and Czech.

The display is CANbus display, it cannot work with UART Bafang motor, please note.(CANbus display is with triangle connector while UART display is with round connector, please check).

Bafang BBS crank arm; bafang M400 /m300/m200 crank arms

Bafang G330 motor core, including Bafang M400 stator or rotor for replacement.

Bafang M400 motor windings is easy to disassemble and replace.

The Bafang M400 G330 motor core are sourced directly from Bafang.

The UART protocol controller will have a "U" mark on the controller, it's EB-BUS connector is with female connector and the display for the motor would be UART protocol with a 5 pin round connector.
If the display connector is with triangle connector, then it is with CAN protocol. The back of the display may also mark “CAN".

Replacing the CAN motor core, you may need to recalibrate the motor.
