Fuel filter
Draining the fuel filter:
NOTE: The fuel filter should be drained after every 100
hours of operation.
1. Make sure there is adequate fuel in the fuel tank and
close the fuel shutoff valve (the handle should be
pointing to the “C” position.) Remove the fuel
sediment bowl. Figure 4-12
2. Open the fuel shutoff valve until all water has been
removed and only fuel flows from the filter base.
3. Install the fuel sediment bowel. The fuel system is
auto bleeding And does not require any manual
bleeding procedures.
Changing the fuel filter:
NOTE: Change the diesel fuel filter every 200 operating
hour.
1. Close the shutoff valve (the handle should be pointing
to the “C” position). Figure 4-12
2. Remove the sediment bowl by rotating the retaining
nut Ref. No. 1. Figure 4-12
3. Open the fuel shutoff valve Ref. No. 2, to drain any
remaining water from the tank. Figure 4-12
4. Discard the fuel element Ref. No. 3, and install a new
element. Figure 4-12
5. Inspect the O rings Ref. No. 4 & 5 and replace if
necessary. Figure 4-12
6. Install and securely tighten the sediment bowl.
7. Open the fuel shutoff valve (the handle should be
pointing to the “O” position), so fuel will flow to the
filter. Figure 4-12
8. Bleed the fuel filter and injection pump as described
below in Bleeding the Fuel System.
Bleeding the fuel system
IMPORTANT:
The 3500/3700 fuel system is designed to bleed
automatically.
1. When the fuel tank is empty
Fill until the fuel level of the tank is at least half full,
then wait about one minute for air to dissipate.
2. When the fuel filter has been replaced:
After replacing the filter, open the fuel shutoff valve.
Air will dissipate for about one minute
NOTE: Fuel tank fuel level must be half full or more for
auto bleed system to function correctly.
NOTE: The 3500/3700 is an auto bleeding system. No
manual bleeding procedures needed.
Engine oil and filter
Checking the Engine Oil Level
Check engine oil daily. Tractor must be setting level and
the engine stopped for a period of time when checking oil
level. Refer to engine manual and maintenance schedule
for oil recommendation and capacities.
Change the engine oil and filter every 100 hours or
annually, whichever comes first.
NOTE: If tractor is being operated in extremely dirty con-
ditions, then it is recommended oil be changed more fre-
quently. If the engine is operated for extended periods of time
at maximum rated power and speed or under other types of
continuous, severe operating conditions the oil and filter
should be changed at 70 hours intervals following the initial
oil change.
Refer to Figure 4-13 for the engine oil filter and dipstick
location.
Refer to Figure 4-14 for the engine oil fill location.
Refer to Figure 4-15 for the engine oil drain location.
Changing the oil
1. Before adding engine oil, place the unit on a level
surface, then remove the dipstick to provide crankcase
ventilation.
2. Add oil at the oil fill shown. Figure 4-14
NOTE: When changing the engine oil, add the exact
amount specified in the engine owner’s manual.
NOTE: Use CD grade or better by API classification
engine oil.
3. Wait about fifteen minutes until the oil gets down to
the oil pan. Then check the oil level with a dipstick. A
