Tool for use in adjusting engine valves

Abstract

A tappet adjusting tool for use in replacing the adjusting pads in the valve lifters of overhead cam, internal combustion engines, such as those commonly used in motorcycles and some automobiles, includes a main tool body having a generally curved lower extension adapted to fit loosely between the cylinder head and the cam of the engine. When in proper position between the cam and cylinder head, the tool is locked into that position such as by a wedge member which is normally swung in toward the tool body but which can be biased into locking position against the cylinder head. A plunger extends from the tool extension and makes contact with the edge of the valve lifter. The plunger is extended to move the lifter and adjusting pad of the engine being worked on away from the cam so that the adjusting pad can be removed and replaced.
