TESTING
NOTE
All carbon must be removed from injection nozzle tip before proceeding with testing.
Use nozzle tester and diesel fuel at 65 to 75F (18 to 24C) 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).
NOTE
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.
INSTALLATION
1.
Position fuel injection nozzle (2) on top of cylinder head (3).
