ABSTRACT:
A push rod is arranged with a central coaxially aligned tubular body, including a bore directed coextensively throughout the tubular body. An internally threaded insert is mounted with an upper distal end of the tubular body threadedly to an elongate threaded rod member formed with a hex boss mounted and formed to an upper distal end of the threaded rod member portion, with an extension rod coaxially aligned with the threaded rod member extending beyond the threaded rod member terminating in a first hemi-spherical tip. A first bore is directed coextensively throughout the rod member, extension rod, and hex boss. A lock nut is threadedly received about the threaded rod member for engagement with the insert hex for locking of the threaded rod member relative to the tubular body. A lower insert rod is received within a lower distal end of the tubular body formed with an abutment ring and terminating in a second hemi-spherical tip. The push rod is accordingly longitudinally adjustable to accommodate varying internal combustion engine spacings from an associated valve tappet to a rocker arm. [A lubrication container is arranged for mounting a set of such push rods prior to use.]
