Fuel injection timing is set in the factory. Fuel injection timing can not change during operation.Note: If a fuel injection pump is removed, replace the old shims (1) with new shims (1) of the same thickness. Old shims (1) must not be reused.Note: If the thickness of the shim (1) is 0.5 mm (0.0197 inch) or the thickness of the shim (1) is below 0.5 mm (0.0197 inch), install beaded shims (1). If the shim thickness is above 0.5 mm (0.0197 inch), install the non-beaded shim. Then install the beaded shim (1). Ensure that the beading on the beaded shim (1) faces upward, toward the bottom of the fuel injection pump.
