ABSTRACT:
A method for assembling a part, such as a spool valve into a bore of a body, such as a transmission valve body. A vacuum means creates suction within the bore in the direction of insertion of the spool valve. A gripper tool attached to a robotic arm supports the spool valve with a light vacuum pressure and maneuvers the spool valve, aligning it sufficiently close to allow the suction in the bore and gravity to pull the spool valve free of the suction of the gripper tool and into the bore.
