How to change the wheel of the door opener?

According to the inquiry, Baixiang Door Industry Network shows.

1. Remove the small cover on the wheel to expose the round shaft with snap ring. Use special disassembly tools to facilitate disassembly.

2. If the wheels are not rusted, you can spray rusted lubricating oil. The wheel is loose and easy to fall off. If you are not afraid of rust between the bearing and the shaft, you need to use the control handle to pull out the edge of the head wheel, and then use the auxiliary pull out.

3. When installing a new wheel, the original iron shaft may have rusted and the shaft becomes larger. It's too tight to pass. Gently grind off the rust on the surface with a hand mill, and then apply some lubricating oil.
