ABSTRACT:
A piston ring gap measuring device for a vehicle includes a master bore having a guide slit on one side and a thickness gauge on the other side. A tolerance scale is provided adjacent to the guide slit and corresponds to tolerance thicknesses of the thickness gauge. A piston ring may be placed onto a ring supporting disk and moved downwardly into the master bore until the piston ring gap encounters a part of the thickness gauge having a thickness dimension greater than the gap thickness. The gap thickness can be obtained from the tolerance scale. The ring supporting disk includes guide tabs movable within grooves in the master bore, and the ring supporting disk is biased upwardly.
