FUEL INJECTION NOZZLES MAINTENANCE - CONTINUED
All carbon must be removed from injection nozzle tip before proceeding with testing.
Use nozzle tester and diesel fuel at 65 to 75°F (18 to 24°C) to test fuel injection nozzle for valve opening pressure. Valve
opening pressure must be 2,050 to 2,350 psi (14,134 to 16,203 kPa).
It is possible for the pressure reading of the gauge to go down fast if the valve makes a noise (chatters) when
it opens. It is also possible for the pressure reading of the gauge to be almost constant when the valve in the
fuel injection nozzle opens.
Install clamp (4) and bolt (1).
Install fuel injection lines (WP 0035 00).
