Abstract: A device useful in replacing springs in equipment such as chain saws, lawnmowers and the like having pull-rope starter assemblies is provided which device comprises a substantially cylindrical or similar member about which the old or new spring is wound and movably positioned on said member a collar capable of being moved into contact with and held against the wrapped spring to hold it in place while it is being moved to and inserted into the equipment. The surfaces of the element against which the spring is wound are substantially smooth to afford a ready sliding of the wound spring off the device into the operative position in said equipment.
