Abstract: A link drive chain repair tool includes a base plate upon which a pair of upstanding longitudinally aligned stud elements extend from its upper face. Clamping means depend from the lower face of the base plate for clamping of the base plate to a surface of the machine driven by the drive chain. One of the stud elements is threaded so as to receive a clamp nut thereon to receive the drive chain to the base plate. A pair of elongated link support members are positioned in spaced parallel relation on the upper face of the base plate to one side of the aligned stud elements so as to be adapted to provide lateral support for an adjacent pair of inner links of the drive chain during removal of a connecting outer link.
