Abstract
A gauge device for measuring the inner diameter of engine related bores comprising a circular body member having a circumferential surface with a cylindrical chamber totally encased therein along a longitudinal axis. A slide pin is housed within the cylindrical chamber which partially extends through upper and lower openings within the circumferential surface. A top flange extends radially from the upper portion of the body member and having a cylindrical dial mount affixed to the front. Disposed equidistance to each side of the top flange is a secondary flange extending radially from the front of the body member each embedded with a magnetic disk. A vertical slot positioned along the longitudinal axis provides the plunger stop means access to the slide pin. A dial indicator means is operatively connected within the dial mount and having a movable plunger extending downward and housed within a spring member which abuts the plunger stop means.
