Abstract
A piston ring locating system includes a resilient ring fabricated in a generally circular configuration having a short height and a length of between about 2 inches and 5 inches with overlapping free ends. One of the ends has a slight bend there adjacent for fitting inside the opposite end. The rings are outwardly biased resiliently to allow varying the circumference of the ring as a function of the cylinder in which it is to be placed. The ring thus forms an interior surface and an exterior surface positionable within the cylinder in which it is to be placed. The ring has a top edge and a bottom edge constituting an abutment surface. Projection means extends outwardly from the exterior surface to a short distance and is adapted to be located on the upper edge of the block of the cylinder with which it is to be utilized.
