In order to replace the external trolley of your motor, you need to disassemble the rail with the belt. To perform this replacement, the easiest way is to position yourself at height on sawhorses, thus avoiding tiring overhead work.
1. Detach the arm connecting the motor trolley to your garage door
2. Disconnect the motor head from its ceiling mount
3. Do the same with the rail attachment on the lintel
4. Place the assembly on sawhorses to loosen the chain: you will find the belt tensioner with a nut and the compression spring at the end of the rail.
5. Once the belt is loosened, remove the motor head and then take out the trolley (whose internal part is just connected to the chain by the drive link)
6. Reverse these steps to put the motor back in place.
