  1. Carefully free the circuit board by taking screws off and letting the board dangle. It will give you more work space.
  2. The chain on the tensioning rod also needs to be out of your way. To loosen it, with a wrench, work on the nut on the rod while holding the chain in place with a pair of pliers or another wrench.
  3. Now you can unscrew and remove the gear assembly out of the unit.
  4. Then to separate the helical gear from the shaft, use the hammer and lightly tap on the pin keeping in its place. If this does not work, apply some WD-40 on the pin and leave it for a few seconds then try again.
  5. Using a hex wrench, attempt to detach the worm gear from the motor shaft by removing the screws on the collar. Take off the gears and washers and remove the remaining screws on the motor.
  6. Now you are ready for reassembly. Reassemble the worm gear and motor shaft using the new worm gear. Put in place the new helical gear and apply a small amount of grease on it.
  7. After the replacement, consult your manual for directions on tightening back the chain and do so. Put back the cover of the door opener
  8. Enjoy your newly repaired door opener.
