Sprinklers may get bent or broken by accident. Most of them are made from hard materials that do not get damaged easily but accidents do happen. Broken Arm Spring can be repaired by, pulling the fulcrum pin with a diagonal or side cutting pilers. You should press the pin in the body and it should come out when pulled.
Please go on performing as we suggest, hold the arm in your hand such that the cup part of the spoon facing you and spoon end of arm pointed to your right, now feed end of spring into the hole which is on your right then on through the hole on the left from the back side. Now look end of spring pointing towards you. Let's bend over end near about half with the help pf needle needle node pilers.
The length of spring is normally more than required. Hold arm with spoon end pointing toward you looking down on top of arm. Now cut off the tag end of the spring at the center line of the arm. Now install arm in the body. With the help of hammer drive fulcrum pin into lower hole. Pull arm around as far as it will go, away from nozzle and feed upper end of spring into the hole that is at a distance from the nozzle. Now feed through the other hole so it extends about "1/8" and bend this extended spring end over sharply to clinch. Rain Bird distributors and dealers provide Arm weights for some sprinklers model in order to maintain proper spring tension.
