A piston ring compressor tool system for safely and conveniently compressing piston rings for easy piston placement into a bore, comprising, in combination;
- a compression skirt comprising an imperforate strip of flexible form-retaining material having an interior surface and an exterior surface and a peripheral edges formed there between including an upper edge and a lower edge and two side edges, the strip being rolled into a hollow generally tapered cylindrical tubular form having overlapping side edges thereby having an internal edge and an external edge, the overlapping configuration allowing for expansion and contraction of the overall radius of the compression skirt during operation and use, the strip being further configured at its upper extent in a shape of a generally outwardly flared upper frustroconical funnel at an angle of between about 10 and 15 degrees and including a continuous upper edge in an essentially circular configuration and with the funnel forming a planar inlet within the interior of the upper edge for receiving a piston and ring assembly and the strip further forming a planar cylindrically shaped outlet at its lower extent within the interior of the lower edge parallel to the plane of the inlet for discharging the piston and ring assembly into a bore of an engine, the compression skirt also having an upper horizontal portion and a middle horizontal portion and a lower horizontal portion, the compression skirt having a generally outwardly curved upper horizontal portion and having a lower horizontal portion and including a continuous lower edge in an essentially circular configuration which is generally plumb to the plane of the opening of the lower edge and having a middle horizontal area which is a transition area between the radial outward curve of the upper horizontal portion and the generally plumb surface of the lower horizontal portion whereby the interior surface decreases in diameter from the upper edge to the lower edge over at least the majority of the length of the skirt;
- a compressing ring assembly comprised of a flat strip of rigid form-retaining material comprising a generally circular configuration having a compression strap and a compressor mechanism, the compression strap having an upper edge and a lower edge and two side edges and an internal surface and an external surface and an edge there between, the surface of the compression strap having a regular surface with parallel slots for receiving the traction from the compressor mechanism, the compressor mechanism, having a rotatable threaded coupler in the form of a bolt with threads for pulling on and shortening the circumference of the compression strap, the threads of the rotatable compressor mechanism being configured to mate to and be in contact with the compression strap thereby enabling the compressor mechanism to shorten and lengthen the overall circumference of the compression strap by rotatably shortening and lengthening the circumference of the skirt;
- and
- an attachment weld coupling the compressing ring assembly to the outside middle horizontal portion of the compression skirt allowing the compressing ring assembly to shorten and lengthen the internal radius of the compression skirt by shortening and lengthening the circumference of the compressing ring assembly.
