Abstract:

An adjustable cam shaft sprocket for allowing small adjustments to a cam shaft. The adjustable cam shaft sprocket comprises an inner member and an outer member, the inner member being placed concentrically within the first circular member and held in place by a fastener. A series of openings located at the perimeter of the inner member and outer member are arranged such that only one pair of openings between the inner member and the outer member are aligned for each hole alignment. A shear pin is inserted through the aligned pair of openings to prevent the inner member from rotating with respect to the outer member. A small adjustment to the cam shaft is achieved by removing the shear pin, rotating the inner member with respect to the outer member so that a second pair of openings is aligned, and re-inserting the shear pin.
