Abstract
The presence and location of a crank pulley bolt on one end of an internal combustion engine is detected by moving a sensing surface on a jig toward the bolt location until it stops, either by contact with the bolt or the pulley, if the bolt is missing. Then a sensor rigidly connected to the sensing jig detects the position of the jig relative to the V-shaped rim of the pulley.
