TP-5867 11/02 8 Section 2 Scheduled Maintenance
2.1 Service Schedule
Perform the items listed in the service schedule at the
designated intervals for the life of the generator set. For
example, an item serviced every 100 hours or 3 months
must also be serviced after 200 hours or 6 months,
300 hours or 9 months, etc. Rough operation, lack of
power, and excessive oil use indicate serious generator
set problems.
2.2 Lubrication System
See Section 2.1, Scheduled Maintenance, for oil
change and oil filter replacement intervals.
See
Section 1.6, Service Views, for the oil drain, oil check, oil
fill, and oil filter locations.
The engine has a positive pressure lubrication system
and low oil pressure shutdown.
2.2.1 Low Oil Pressure Shutdown
The low oil pressure shutdown feature protects the
engine against internal damage if the oil pressure drops
below preset limits because of oil pump failure or other
malfunction.
It does not protect against damage
because of operating with the oil level below the safe
range—it is not a low oil level shutdown.
2.2.2 Oil Level Check
Check the oil level regularly and add oil as needed to
protect against running out of oil. See Figure 2-1 for the
dipstick and oil fill locations. Do not check the oil level
when the generator set is running.
Shut down the
generator set and wait several minutes before checking
the oil level.
2.2.3 Engine Oil Recommendation
Use synthetic oil of API (American Petroleum Institute)
Service Class SG or SH. Synthetic oil oxidizes and
thickens less and causes fewer deposits on the engine
intake valves and pistons than other oils.
If nonsynthetic oil is used, select the viscosity based on
the air temperature at the time of operation.
See
Figure 2-3.
