ABSTRACT:
A flexible skirt for preventing debris such as dirt and rust, for example, from accumulating on the seal between the piston and cylinder of a hydraulic vehicle lift assembly. The skirt comprises an essentially flat piece of material cut or formed such that it has an inside perimeter of substantially the same diameter as the piston diameter and an outside perimeter of a larger, predetermined diameter. Two free ends extending from the inside to outside perimeter include releasable attachment means allowing the skirt to be wrapped around and encircle the piston with the two ends then attached back together. A series of spaced, through holes are provided in the skirt in the area between the inside and outside perimeter for passing bolts therethrough which have been removed from the underlying retaining ring which holds the seal in place. With the skirt placed around the piston and in covering relation to the retaining ring, the bolts are passed through the holes in the skirt and are secured back into their original holes in the retaining ring such that the skirt is secured thereto.
