ABSTRACT:
A driven shaft is assembled into a driving member using a hydraulic actuator while measuring the supply pressure to the actuator during the press-in operation of the driven shaft into the driving member and while monitoring the stroke of the hydraulic actuator. The apparatus provides a first indication if a pressure rise occurs after the actuator stroke has reached a predetermined assembly position and a second indication if a pressure rise occurs before the actuator stroke has reached the predetermined position, thereby displaying whether or not the driven shaft is correctly fitted to the driving member.
