ABSTRACT:
A device for compressing a coiled spring comprised of multiple coils used in combination with a motor vehicle suspension strut under tension including a first hollow tube and a second smaller tube adapted to fit slidably into the first hollow tube. First and second compressor plates are provided to engage spaced coils. A rotatable drive shaft compresses the coiled spring to reduce tension against the strut's retention end plates to enable the safe, quick and easy removal and replacement of the strut. Each compressor plate consists of an open ended slotted central portion and two side sections defining an upper slotted section and a narrower bottom slotted section with an annular interior edge. The upper slotted section is provided to seat coils with a large diameter. The bottom slotted section is provided to seat coils with a small diameter.Openings are formed within the plates' side sections to receive elongated rods for preventing the tensioned coiled spring from slipping from its placement while awaiting the installation of a new strut.
