1. Remove the solenoid.
2. Remove the injection pipes and glow plugs.
3. Set a pressure tester to the fuel injection pump.
4. Install the injection nozzle (2) jetted with the proper injection
pressure to the injection pump pressure tester (1).
5. Run the starter to increase the pressure.
6. Stop the starter when the fuel jets from the injection nozzle. After
that, turn the flywheel by the hand and raise the pressure to
approx. 18.63 MPa (190.0 kgf/cm
2
, 2702 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 18.63 to 17.65 MPa (190.0 to
180.0 kgf/cm
2
, 2702 to 2560 psi).
8. Measure the time needed to decrease the pressure from 18.63 to
17.65 MPa (190.0 to 180.0 kgf/cm
2
, 2702 to 2560 psi).
9. If the measurement is less than allowable limit, replace the pump
with new one or repair with a Kubota-authorized pump service
shop.
NOTEQ
• Never try to disassemble the injection pump assembly. For
repairs, you are strongly requested to contact a Kubota-
authorized pump service shop.
