MAINTENANCE
To prevent the engine from accidentally starting, dis-
connect the negative battery cable before servicing
the engine.
------------------------------------------------------------------------
See Table D.1 for a summary of maintenance inter-
vals for the items listed below. More frequent service
may be required, depending on your specific applica-
tion and operating conditions. See the Kubota Engine
Operator's Manual for further information
OIL
Check the oil level before starting engine or
daily.
BE SURE TO MAINTAIN THE OIL LEVEL .
Change the oil for the first time after 50 hours of oper-
ation. Then, under normal operating conditions,
change the oil as specified in the maintenance sched-
ule.
CHANGING THE OIL
Change the oil, while the engine is still warm, as fol-
lows:
1. Drain the oil from the drain plug located on the
engine bottom, as shown in Figure D.1.
2. Replace the plug and tighten it securely.
3. Remove the oil fill cap and add oil until the level
reaches the full mark on the dipstick. The quantity
of oil required for an oil and oil filter change is 5.4
quarts (5.1 L). Use oil that is rated for diesel
engine service (API classification CD/CE). Use
SAE viscosity grades per the following table:
4. Reinstall the oil fill cap and the dipstick and start
the engine. Run for several minutes and stop
engine - Wait 5 minutes to allow the oil to come
down to the oil pan and check oil level again.

OIL FILTER
Change the oil filter the first time after 50 hours of
operation. Then, under normal operating conditions,
change the oil filter at every oil change.
Change the oil filter as follows:
1. Drain the oil from the engine and allow the oil filter
to drain.
2. Remove the old filter (spin it off) and discard it.
Wipe off the filter mounting surface and adapter.
3. Apply a thin coat of new oil to the rubber gasket on
the new oil filter.
4. Spin the new filter on to the mounting adapter until
the gasket just touches the mounting surface, then
turn it down another 1/2 to 3/4 turn. Do not over-
tighten the new filter.
5. Refill the engine with the proper amount and type
of oil as described in the CHANGING THE OIL
section. Start the engine and check for leaks
around the filter element. Correct any leaks (usu-
ally by retightening the filter, but only enough to
stop leaks) before placing the RANGER 300 back
in service.
6. If there are no leaks, stop the engine and recheck
the oil level. If necessary, add oil to bring the level
up to the FULL mark, but do not overfill.
