ABSTRACT:
An automobile type hydraulic jack is converted from manual to powered actuation by removing the manual actuation handle socket and associated linkages and attaching a frame carrying an electric gear motor with an eccentric rotary output cam situated to reciprocate the original pump plunger to raise the jack. The frame is, preferably, attached to the pump plunger cylinder projection which extends from the jack base. Alternate frames provide for attachment to the pump fluid reservoir housing or to the jack base.
