  • Patent number: 11111981
    Abstract: A method of forming a dirt shield on a shock absorber includes positioning a mold over a portion of the shock absorber, heat shrinking a sleeve onto the mold, and removing the mold from the portion of the shock absorber such that the sleeve after heat shrinking remains on the shock absorber and forms the dirt shield. The shock absorber includes a piston rod, a mount rigidly attached to the piston rod, and a bushing secured to the mount. Prior to heat shrinking the sleeve, the sleeve slides over the bushing, and after heat shrinking the sleeve the bushing has an outer dimension greater than an inner dimension of the dirt shield. Also, a plurality of sleeves having the same inner dimension is used to form a plurality of dirt shields having different inner dimensions.
