ENGINE
Fuel Tightness of Pump Element
1. Remove the engine stop solenoid.
2. Remove the injection pipes.
3. Install the injection pump pressure tester (refer to “8. SPECIAL
TOOLS” at “G. GENERAL” section) to the injection pump.
4. Install the injection nozzle (2) jetted with the proper injection
pressure to the injection pump pressure tester (1). (Refer to the
figure.)
5. Set the speed control lever to the maximum speed position.
6. Run the starter to increase the pressure.
7. If the pressure can not reach the allowable limit, replace the
pump with new one or repair with a Kubota-authorized pump
service shop.
NOTE
Q
• Never try to disassemble the injection pump assembly. For
repairs, you are strongly requested to contact a Kubota-
authorized pump service shop.

Fuel Tightness of Delivery Valve
1. Remove the engine stop solenoid.
2. Remove the injection pipes.
3. Set a pressure tester (refer to “8. SPECIAL TOOLS” at “G.
GENERAL” section) 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 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 (from 190
to 180 kgf/cm
2
, from 2702 to 2560 psi).
8. Measure the time needed to decrease the pressure from 18.63 to
17.65 MPa (from 190 to 180 kgf/cm
2
, from 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.

• Never try to disassemble the injection pump assembly. For
repairs, you are strongly requested to contact a Kubota-
authorized pump service shop.
