Place the three hard washers behind the plate from Tooling (A) and install bolt (19). Note: The plate must be installed in order to keep camshaft drive gear (21) on the camshaft during the removal procedure. The plate can be used from the right-hand camshaft drive gear. If necessary, fabricate a plate that has a diameter of 76 mm (3.0 inch). The thickness of the plate must be 19.00 mm (0.750 inch) thick. Drill a hole 22.00 mm (0.875 inch) in the center of the plate.
