Fuel Tightness of Pump Element
1. Remove the bonnet and air cleaner.
2. Remove the muffler.
3. Disconnect the accelerator wire.
4. Remove the air cleaner stay.
5. Remove the injection pipes and glow plugs.
6. Install the air cleaner stay.
7. Connect the accelerator wire.
8. Install the injection pump pressure tester to the fuel injection
pump.
9. Set the speed control lever to the maximum speed position.
10.Turn the flywheel ten times or more to increase the pressure.
11.If the pressure can not reach the allowable limit, replace the
pump element or injection pump assembly.
NOTE
■
• Apply a liquid gasket (Three Bond 1215 or equivalent) to
both sides of the solenoid cover gasket.

Fuel Tightness of Delivery Valve
1. Remove the bonnet and air cleaner..
2. Remove the muffler.
3. Remove the injection pipes and glow plugs.
4. Install the injection pump pressure tester to the fuel injection
pump.
5. Set the throttle lever to the maximum engine speed.
6. Turn the flywheel and raise the pressure to approx. 14.7 MPa
(150 kgf/cm
2
, 2130 psi).
7. Now turn the flywheel back about half a turn (to keep the plunger
free). Maintain the flywheel at this position and clock the time
taken for the pressure to drop from 14.7 to 13.7 MPa (from 150
to 140 kgf/cm
2
, 2130 to 1990 psi).
8. Measure the time needed to decrease the pressure from 14.7 to
13.7 MPa (from 150 to 140 kgf/cm
2
, from 2130 to 1990 psi).
9. If the measurement is less than allowable limit, replace the
delivery valve.
