Abstract:

The present invention is directed to an extractor tool for removing valve lifters from an engine block or head in a fast convenient manner and with a minimum of manual dexterity or strength. The prior art devices provide tools having complicated force multiplying linkages and camming devices associated with a plurality of groove engaging fingers which are only adapted to engage a single groove or oil hole in the valve lifter body. The present invention overcomes these deficiencies by providing an extractor tool which is adapted to engage multiple grooves within the valve lifter body and assures precise alignment therebetween to eliminate any cocking of the lifter body relative to the extractor tool during removal of the lifter from the enginer block.
