How to swap the motor core on Surface 604 Boar Hunter/Boar Explorer/TwistUpdated 2 years ago

Additional Notes

- It's easier to remove the rear wheel with the bike upside down. 

- You may need a 10 mm wrench to turn the axle slightly. To make it easier to remove the wheel. 

- Good to wear nitrile mechanic gloves. 

- Add a bit of lithium grease to the inner drive ring in the wheel. Before installing the motor core. 

- Make sure the derailleur B tension screw hanger is positioned correctly when reinstalling. 

- You want the axle wire notch facing down when installing the wheel. When installing with bike upside down, the notch should be facing up.
