Abstract:
1. A tool assembly for tappet adjustment in an internal combustion engine using a gap gauge wherein the tappet adjustment requires rotation of an adjustment screw and a locking nut mounted thereon, said tool assembly comprising: a socket having a first end opening sized to fit over the locking nut and in contact with the locking nut so that rotating the socket causes the locking nut to rotate, the socket having an upper opening of a non-circular cross-section sized to receive means for rotating the socket around its central axis, wherein the means for rotating the socket around its central axis is a hollow rod having a first and second portion, the first portion insertable into the upper opening of the socket, an opening in the end of the first portion of the hollow rod having an internal diameter sized to fit over the adjustment screw without interfacing with rotation of the adjustment screw, the second portion having an outer non-circular cross-section sized and configured to fit in the non-circular upper opening of the socket, the hollow rod having a lumen centrally located through the first and second portion to allow placement of a tool there through for rotation of the adjustment screw.
