c. Test valve seat tightness.
(1)
With injection nozzle (1) installed to the nozzle tester (2), pump handle until pressure is
raised to 1849 psi (12.75 MPa) and sustain pressure for 10 seconds.
(2)
Observe injection nozzle (1) for fuel leaks. If leaks are observed, replace injection nozzle.
d. Test Fuel Injection Pressure.
(1)
With injection nozzle (1) installed to the nozzle tester (2), slowly move the tester handle
and measure the pressure at which the nozzle begins to spray fuel.
(2)
If pressure is not between 1991 and 2133 psi (13.72 to 14.70 MPa) and/or the nozzle
leaks, replace the injection nozzle.
