Abstract
A hardenable insert for use with a reversible track link in an endless track assembly to be interposed between the worn side of a used track link and a track shoe applied thereto. The pad includes a matrix which is formed of a deformable binder or filler material, an uncured resin flowable in its uncured state and rigid when cured. The resin impregnates the pad. The pad also includes a plurality of rupturable capsules dispersed throughout the pad, the capsules containing a curing agent for the resin so that when the pad is interposed between the worn side of a reversible track link and a track shoe, and the track shoe is clamped to the track link, the pad will deform to conform to irregularities at its interface with the track link and the capsules will rupture to cause the curing agent to cure the resin to rigidify the pad and thereby provide a smooth interface to prevent loosening of the track link and the track shoe during subsequent use.
