B. FUEL LECTION PRESSURE
1. Set the injection nozzle to the nozzle tester.
2. Measure the injection pressure.
3. If the measurement is not within the factory
specification, adjust with the adjustment washer (1)
inside the nozzle holder.
(Reference)
Pressure variation with 0.1 mm (0.004 in.) difference of
adjusting washer thickness is approx. 10 kgf/cm².

• Never contact with spraying diesel fuel under
pressure, which can have sufficient force to pen-
etrate the skin, causing serious personal injury.
• Be sure nobody is in the direction of the spray.

7.2.10 FUEL SYSTEM
A. DELIVERY VALVES FUEL TIGHTNESS
1. Remove the injection pipes, glow plugs and the in-
let manifold, and install the pressure tester.
2. With the speed control lever at the fuel injection
position, turn the crankshaft counterclockwise
(facing the flywheel) until the pressure build up to
the fuel injection pressure.
3. Release the pressure in the delivery chamber by
moving down the plunger to bottom dead center
(turn the crankshaft clockwise approx. 1.57 rad (90°)
from the F1 timing).
4. If the pressure drop for 5 seconds exceeds the al-
lowable limit, replace the delivery valve or pump
assembly.
5. If the pressure does not built up, replace the pump
element with new one and test again.
