ABSTRACT:
Apparatus and a method for attaching replacement frictional lining material to a face of a lock-up piston for a torque converter of an automatic transmission. A housing encloses a pair of pressure plates which are electrically heated to automatically-controlled temperatures. A cylinder-and-piston assembly carries one of the pressure plates between an open position permitting a lock-up piston and a replacement friction lining material to be placed atop the other pressure plate. Closure of the door of the housing initiates an automatic cycle of application of pressure for a predetermined amount of time during which the heated pressure plates activate an adhesive material. An automatic timing device is adjustable to control the duration of application of pressure through operation of an electrically-controlled air valve.
