Typical example

Type of fuel injection pump ... In-line cassette

Direction of rotation of the camshaft for the fuel injection pump ... Clockwise from the drive end

(1) Tighten the mounting nuts and setscrews to the following torque. ... 15 N·m (11 lb ft)

(2) Tighten the delivery valve holders to the following torque. ... 42 N·m (31 lb ft)

(3) Shim

The shim adjusts the timing of the fuel injection pump. A thicker shim regresses the timing. A thinner shim advances the timing. The timing changes 1 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, new shims, which have the same thickness as the original shims, must be installed.

If any of the following new components are installed, new shims must be used.

• Camshaft

• Cylinder block

The following thicknesses of shims are available:

• 0.20 mm (0.008 inch)

• 0.25 mm (0.010 inch)

• 0.30 mm (0.012 inch)

• 0.35 mm (0.014 inch)

• 0.40 mm (0.016 inch)

• 0.50 mm (0.020 inch)
