ABSTRACT:
A bench mounted spring compressor is utilized to compress a helical coil spring of a MacPherson strut suspension assembly. The compressor includes a fixed base member having an adapter attaching the shock absorber thereto. A vertically movable tube is arranged to telescope within a tube secured to the fixed base member. The upper end of the movable tube includes an engaging shoe head assembly which is horizontally movable relative to the vertically movable tube. A manually operable ball nut-helical screw arrangement moves the engaging shoe toward and away from the fixed base member. The ball nut-helical screw arrangement is freely movable in one direction of rotation but inhibited in the opposite direction of rotation. The telescoping tubes are prevented from rotating relative to one another.
