(3) Shim

The shim adjusts the timing of the fuel injection pump. A thicker shim retards the timing. A thinner shim advances the timing. The timing changes one degree for each 0.10 mm (0.004 inch) difference in the thickness of the shim. More than one shim can be used. If the fuel injection pump is reinstalled, a new shim, which is the same thickness as the original shim, must be installed.

If any of the following new components are installed, a new shim which has a thickness of 0.5 mm (0.020 inch) must be used until the timing of the fuel injection is correctly adjusted.

• Camshaft

• Cylinder block

The following thicknesses of shims are available:

• 0.10 mm (0.004 inch)

• 0.20 mm (0.008 inch)

• 0.30 mm (0.012 inch)

• 0.40 mm (0.016 inch)
