Compact and portable hydraulic extracting and installing apparatus and associated method

摘要

A compact and portable hydraulic apparatus for extracting and installing a tight fitting vehicle component may include a main hydraulic cylinder having an open proximal end, a cover attached to the open proximal end of the main hydraulic cylinder, a grip holder attached to the main hydraulic cylinder, a plurality of grip members affixed to the grip holder and spaced from the main hydraulic cylinder, and an actuating member statically mated to the main hydraulic cylinder. In this manner, the actuating member is capable of being engaged with an existing shaft of an existing pulley. Advantageously, the actuating member is axially reciprocated through the open proximal end of the main hydraulic cylinder, relative to a stationary position of the grip holder and the grip member respectively.
