Abstract

Standard tools for removing a spring from a mounting bracket is a pair of pliers or a spring hook. If the spring tang is long and extends through a hole in the bracket, there may not be sufficient clearance to twist the spring back through the hole. If the spring is large, the user may not have sufficient strength to pull tension on it or the spring tool itself may break.

Standard tools for removing a spring from a mounting bracket is a pair of pliers or a spring hook. If the spring tang is long and extends through a hole in the bracket, there may not be sufficient clearance to twist the spring back through the hole. If the spring is large, the user may not have sufficient strength to pull tension on it or the spring tool itself may break.

For example, as shown in FIG. 1, a spring 12 is large, has a long tang, and is accessible from only one area of the machine.

This method could cause injury (eye and hand) if the spring tool breaks or if the...
