Abstract: A camshaft alignment tool and method uses a main body having at least three projections to engage cogs on cog wheel driven double overhead camshafts. The tool is used to maintain the cog wheels in a fixed relationship with respect to one another during replacement of a cooperatively toothed timing belt. Use of the tool enables a single technician to change the timing belt on a high performance internal combustion engine employing double overhead camshafts even if the cam surfaces are aggressive and the valve return springs employ large spring constants.
