• Do not loosen the injection pipe when the fuel is under high
pressure (within five minutes of stopping the engine).
1. Remove the window cover (1) from the flywheel housing (2).
2. Put the piston of the number 4 cylinder at TDC.
• When positioning the piston of the 4th cylinder to TDC,
rotate the flywheel counterclockwise and align the TC mark
(4) on the flywheel with the mark (3) on the housing of the
flywheel. If the supply pump gear timing mark (8) meshes
with idle gear (6), then the piston of the 4th cylinder is TDC.
If they do not mesh, rotate the flywheel counterclockwise
one revolution.
3. Make a temporary mark (5) with a white paint marker pen on the
tooth of idle gear (6).
• This mark is extremely useful during reassembly of the
supply pump gear and idle gear (6) to get the timing right.
4. Fix the flywheel in place.
5. Loosen the supply pump gear's mounting nut (9).
6. Remove the supply pump (10).
• Do not disassemble the supply pump.
• Store the supply pump so it does not get any dust in it.
