Abstract:
1. A method of connecting or disconnecting a water pump pulley attached by a threaded shaft to a connector on a fan clutch, said pulley having at least a pair of fasteners each with a fastener head extending from a surface of the pulley, said heads being adjacent, spaced apart and next to the fan clutch to provide a narrow space between said surface and the fan clutch that is no greater than ¾ inch, said method including the steps of (a) providing a tool comprising a tool head sized to fit into the space between the surface of the pulley and the fan clutch having a thickness from {fraction (1/16)} to ¾ inch and a width from 2 to 10 inch, said tool head being integral with a handle, the handle defining a tool central longitudinal axis, said tool head including a hook arm and a lever arm joined together to provide a common edge, said common edge having a terminal end including said hook arm, said hook arm and lever arm configured and positioned relative to each other to engage separately the head of each fastener when the tool is positioned in the space between said surface and the fan clutch, said hook arm including an outwardly projecting tip from which an arcuate edge portion curves inward to enable said hook arm to grasp one fastener head of one fastener of said adjacent pair, with the arcuate edge portion bearing against said one fastener head, and said lever arm having a straight edge portion substantially extending to the longitudinal axis, said straight edge portion bears against the adjacent fastener head when said hook arm is grasping said one fastener head of said one fastener, said straight edge portion having an inner end merging with an inner end of the arcuate edge portion, said straight edge portion having a length from 1 to 10 inches, said arcuate edge portion and said straight edge portion forming, at least in part, said common edge and the arcuate edge portion being at a terminal end of the common edge, (b) inserting into the space between said surface and the fan clutch said head of the tool and grasping said one fastener head with the hook element and engaging the other fastener head with the straight edge lever element, and (c) while grasping said one fastener head with the hook element and engaging the other fastener head with the straight edge lever element, inserting into said space a second tool and grasping the connector on the fan clutch, (d) while both tools are engaged, turning one or both said tools to disconnect or connect the threaded shaft of water pump pulley and the connector on the fan clutch.
