(optional) Step 1a: Adjust motor gear meshing

The gears are adjusted at the factory and this should not need to be done on a new B3RB. However over time it may be that they need adjustment. Follow this procedure to re-adjust the gear meshing. Diagnose Motor Gear Meshing Issue

1. Rotate the Wheels Gently: Start by gently rotating the wheels of the B3RB that the motor is driving.

2. Listen Carefully: Listen to the sound of the gears as you rotate the wheels. Ideally, the gears should mesh smoothly without any grinding or excessive noise.

3. Feel for Resistance: As you rotate the wheels, feel for any resistance or unevenness. This could indicate that the gears are not meshing properly.

Adjust the Gear Mesh

1. Locate the Motor Mounting Bracket: Identify the motor mounting bracket where the motor is attached to the chassis or frame of your device.

2. Loosen the Adjustment Screws: Typically, there are two screws at the front of the motor mounting bracket that secure the motor in place. Use an appropriate screwdriver to gently loosen these screws. You don’t need to remove them completely, just enough to allow slight movement of the motor.

3. Adjust the Motor Position: Apply mild pressure to the motor in the direction that will improve the gear meshing. This usually means pushing the motor closer to the gear or slightly adjusting its angle to ensure the teeth of the gears are aligned properly.

4. Check and Tighten: After adjusting, rotate the wheels again and listen for any improvement in the gear meshing. Once satisfied with the adjustment, carefully tighten the screws back into place to secure the motor in its adjusted position.
