SECTION 5
SERVICE AND PREVENTATIVE MAINTENANCE
5.1 INTRODUCTION
This section covers service for the generator set and general engine service. Refer to the Kubota engine workshop
manual, Section 1.1, for additional engine servicing.
WARNING
!
Beware of moving V-belt and belt driven components.
5.2 PREVENTATIVE MAINTENANCE SCHEDULE
A tabular listing of the recommended preventative maintenance activities and schedule is provided in Table 5–1 .
5.3 BATTERY SERVICE
When replacing the battery, determine whether the unit was supplied with a mat in the battery tray. If so equipped,
the mat must also be replaced.
5.4 ENGINE SERVICE AND COMPONENTS
5.4.1 Bleeding the Fuel System
The unit is equipped with a mechanical fuel lift pump mounted on the engine next to the injection pump. The fuel
system is a closed circuit which will require bleeding if loss of fuel has occurred. To fill and bleed the system, do the
following:
1. Turn fuel bleed valve (Red, see Figure 2.8 ) counterclockwise until fully opened.
2. Turn the top of the manual priming pump (see Figure 5.1 ) counter-clockwise to unlock it, and then hand
pump the manual plunger until a positive pressure (resistance) is felt. This will indicate fuel flow.
3. Depress and turn the top of the manual priming pump clockwise to lock in place.
4. Start engine. (Refer to Section 2.3 ).
5. When engine is running properly, turn fuel bleed valve clockwise until fully closed.
5.4.2 Servicing Fuel Pump Internal Filter
The internal fuel filter may become plugged or restricted with foreign particles or wax, which can develop if the
wrong grade of fuel is used or untreated fuel is used in cold weather, contaminating the fuel. If the internal filter is
plugged, the engine will lose power. Therefore, the filter must be cleaned on a regular basis. The quality of the fuel
will affect the filter cleaning schedule (refer to
Section 5.2 ).
1. Turn nut counter-clockwise to loosen and remove.
2. Remove banjo fitting and let it hang loose.
3. Turn filter counter-clockwise and remove. Check and clean.
4. To install, reverse steps 1 through 3.
