Hi,I agree with you ,there is a load of movement in the gear mechanism I thought maybe the bearings are shot, when I got it the hub wouldn't move at all.managed to loosen it so I could push it home,buying a puller so I can remove the assembly for a look,don't know if the bearings come out .But...

Well I thought it only right to tell you how I got on ,I had to swap the free wheel and freewheel plate from another broken motor ,I cleaned the display terminals resoldered the sensor ,moved the wheel and it registered,now I've got to make a bracket for the broken sensor,I'm really...

You were right about that sensor,I decided to check the display as I noticed it came off ,the contacts were corroded ,cleaned them and tested the the wheel sensor by turning the wheel ,it worked.

Some infra red is visible ,I take it the sensor isn't, thank you for replying.

Hello,does anyone know how to test the sensor,I can't see any light on the sensors but maybe you can't! The display woks fine but no motor response ,there is five volts on the sensor board from + to - pins 1 and 3.

Thanks once again you've really helped ,even answered questions I would have asked ,I did try to search but got bogged down with information.

Your right ,but wouldn't you lose the torque feature, out of curiosity the crenalated rings are they set open or closed. I'm going to look At the threads you suggested now . Have you ever worked on a brose motor.

Just sorted the drive chain problem reassembled the pedal sensor grid etc but was sure to bare in mind all the locating lumps so no wobble ,I've lost all the little shim washers though,must replace them.
