Engine
b. Radiator/Oil Cooler Installation
1. Install the isolator mounts to the bottom of the
radiator. Place the radiator/oil cooler in the engine
compartment at its original orientation. Secure the
radiator with the previously used hardware.
Note: Be sure there is adequate clearance between the
radiator and the engine fan.
2. Install the radiator fan shroud.
3. Uncap and reconnect the previously labeled
hydraulic hoses to the appropriate locations.
4. Install both radiator hoses, and with the clamp
installed over the hose, work the hose onto the
radiator, and tighten the clamp.
5. Install both charge air tubes to the charge air cooler.
6. Install the coolant overflow tank (Cummins Only).
7. Open the radiator cap and fill the radiator completely
with a 50/50 mixture of ethylene glycol and water.
Replace and tighten the radiator cap. Refer to
Section 2.4, “Fluid and Lubricant Capacities,” for
proper capacities.
8. Connect the battery negative (-) cable to the battery
negative (-) terminal.
9. Run the engine to operating temperature. Visually
check for leaks with the engine running. Check the
coolant level in the overflow bottle and fill, or drain,
as necessary.
10. Install the engine dust shield.
7.8 ELECTRICAL SYSTEM
The engine electrical system, including the starter,
alternator and primary wiring, is described in Section 9.5,
“Electrical System Schematics.”
7.9 FUEL SYSTEM
7.9.1 Diesel Fuel
Fuel represents a major portion of machine operating
costs and therefore must be used efficiently. ALWAYS
use a premium brand of high-quality, clean diesel fuel.
Low cost, inferior fuel can lead to poor performance and
expensive engine repair.
Note: Use only diesel fuel designed for diesel engines.
Some heating fuels contain harmful chemicals that can
seriously affect engine efficiency and performance.
Inform the owner/operator of the machine to use #2
diesel fuel, unless ambient temperatures are below 0° C
(32° F). When temperatures are below 0° C (32° F), a
blend of #1 diesel and #2 diesel fuels (known as
“winterized” #2 diesel) may be used.
Note: #1 diesel fuel may be used, however, fuel
economy will be reduced.
Use a low-sulfur content fuel with a cloud point (the
temperature at which wax crystals form in diesel fuel) at
least 10° below the lowest expected fuel temperature.
The viscosity of the fuel must be kept above 1.3
centistrokes to provide adequate fuel system lubrication.
Note: When using diesel fuel with a sulfur content below
1.3 percent, the filter change interval may be increased
by 75 hours. Do not use fuel with a sulfur content above
1.3 percent is not recommended.
7.9.2 Fuel Tank
John Deere
Note: The fuel tank is a one piece unit. It is located on the
right side of the machine directly behind the hydraulic oil
reservoir. If it is determined that the fuel tank must be
removed, the fuel must be drained before tank removal.
Always dispose of fuel properly.
a. Fuel Tank Removal
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom, lower the boom,
place the travel select lever in the (N) NEUTRAL
position, engage the parking brake, and shut the
engine OFF.
2. Place a Do Not Operate Tag on both the ignition key
switch and steering wheel, stating that the machine
should not be operated.
NOTICE
Due to the precise tolerances of diesel injection
systems, keep the fuel clean, and free of dirt and
water. Dirt and water in the fuel system can cause
severe damage to both the injection pump and the
injection nozzles. Use ASTM #2 diesel fuel with a
minimum Cetane rating of 40. #2 diesel fuel gives the
best economy and performance under most operating
conditions. Fuels with Cetane numbers higher than
40 may be needed in high altitudes or extremely low
ambient temperatures to help prevent misfiring and
excessive smoking.
