ABSTRACT:
A hydraulic valve lifter removal device (10) for removing hydraulic valve lifters from an engine (14). The removal device (10) comprises an elongated lifter retrieval housing (24) having a closed distal end portion (26) for being inserted through the cam shaft opening (34) of an engine (14) and into the interior of the engine. The housing (24) also includes a proximal end portion (28) which remains exterior to the engine for manipulating the housing (24). A plurality of lifter receiving openings (32) accessing the interior of the housing (24) are selectively spaced along the length of the housing (24). The lifter receiving openings (32) are selectively spaced along the length of the housing (24) such that upon selective positioning of the housing (24) at least a plurality of the openings (32) register with a plurality of lifter receptors (16) within the engine (14) so as to be receptive of the associated hydraulic valve lifters (12) as they are dislodged from the receptors (16), thereby allowing the lifters (12) to be retrieved from the interior of the engine (14).
