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.

Figure 4-12

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
