Abstract
A method and apparatus for providing an improved static timing between a crankshaft and a camshaft in an internal combustion engine. The crankshaft and camshaft are locked into predetermined rotational positions to set the desired timing between the crankshaft and camshaft. The camshaft is locked into its predetermined rotational position using a camshaft timing member positioned between a flat portion formed on an outer peripheral surface of camshaft and an adjacent portion of said engine, such as the cylinder head. This positioning of the camshaft timing member prevents the camshaft from rotating and locks the camshaft into the desired predetermined rotational position for setting the static timing with respect to the crankshaft. The crankshaft in locked into its predetermined position using a crankshaft timing pin inserted through the engine block and positioned into a slot formed in a counterweight on the crankshaft. The slot in the counterweight is shaped so as to fittingly receive the crankshaft timing pin. The crankshaft timing pin prevents the crankshaft from rotating and locks the crankshaft into the desired predetermined rotational position for setting the static timing w…
