Abstract
A series of thin shims with concave profiles matching the cylinder rod is supported from the cylinder. A carrier mechanism attached to either the rod end or cylinder barrel supports a plurality of shims that can be pivoted between storage positions and stop positions. A pivoting and spring loaded latching arm works in conjunction with notches on the shim profile to lock individual shims in either the working or the storage position. Multiple shim stack operating ranges are provided by insertion of thicker shims between the main shim pack and the mating part. The mating part can be a cylinder rod end or cylinder rod guide, depending upon the shim pack carrier mechanism.
