Wide throw door hinges installed on a door has an automatic closing mechanism and when the door stops closing properly or completely, uses the hinge to be repaired. There are two basic repair options for a self closing hinge on a door adjustment or replacement and either option is easy to determine and complete. Make the adjustment necessary for self-closing hinge by opening the door and allowing it to close. If the door closes too hard, the spring tension of the hinge must be reduced and if the door closes too slowly or does not the full lock once closed, the spring tension should increase. Close the door to access the hinges tension located at the top or bottom end of the hinges spring cylinder. The tension is a thin horizontal ring with holes evenly distributed around its circumference, with a hole containing a metal rod that locks the tension ring’s position.
Lower the spring tension of the hinge by inserting the end of a needle or nail into the second or third inch hole of the metal locking pin. Push the key lightly against the frame to remove the metal pin, and then slide it toward the nearest free hole against the frame. Release the pressure on the clamping ring and release the pin against the wide throw door hinges of the film. Increase the spring tension of the hinge by inserting the end of one needle or nail into the tension of the other free opening of the metal locking pin and pressing the tension against the frame. Slide the metal pin into the next empty hole on the door side and release the clamp ring to push it against the hinge.
Pull the door open so that the door closes to assess the spring tension adjustment. Repeat steps 3 or 4 as necessary to complete the wide throw door hinges adjustment until the door closes properly. If adjustment has not solved the problem, the hinge no longer works properly and needs to be replaced. Release self closing hinge spring tension completely following the procedure described. Open the door completely and remove self-closing hinge’s side leaf screws. Extract the remaining door hinge pins by pushing up the bottom of the legs using a hammer and nails to remove the legs, and then remove the door from the opening.
