Pump Element Fuel Tightness
1. Install the p ..essure tester (See page S-53) to the fuel in ­
jection pump.
2. With the speed control lever at the maximum position of
the fuel injection, rotate the flywheel to raise the fuel
pressure to 39.23 MPa (400 kgf/cm
2
,
5689 psi).
3. Measure the falling time of the fuel pressure from 39.23 to
34.32 MPa (from 400 to 350 kgf/cm
2
,
from 5689 to 4978
psi).
4. If the measurement is less than the allowable limit, replace
the pump element or the injection pump assembly.
• IMPORTANT:
• After replacing the pump element, adjust the amount of
the fuel injection on the specified test bench.
