Engine: Perkins 1104-42 & 1104-42T
7-6 3508PS, 3509PS, 3512PS, 3513PS, 4008PS, 4009PS, 4012PS, 4013PS, 4017PS, 40.8, 40.9
15. Remove the air conditioner condenser (if equipped)
from the radiator assembly.
16. Carefully lift the radiator/oil cooler out of the engine
bay.
Note: If applicable the radiator can be removed with the
radiator frame. Remove the five bolts holding the
radiator frame to the machine frame and remove the
radiator and radiator frame as one unit.
b. Radiator/Oil Cooler Installation
1. Install the isolator mounts to the bottom of the
radiator. Insert radiator through the machine frame
mounts and install the washers and new locknuts.
2. Install the air conditioner condenser (if equipped) to
the radiator assembly.
3. At the top of the radiator, install the isolator mounts.
Install the washers and new locknuts on the back
side of the weldment.
4. Be sure the engine fan has clearance in regard to
the radiator. Install the radiator fan shroud.
5. Uncap and connect the previously labeled oil cooler
top (6) and bottom (7) hoses to their appropriate
locations.
6. Uncap and connect the previously labeled radiator
top (4) and bottom (5) hoses to their appropriate
locations.
7. Uncap and connect the previously labeled air
conditioner hoses (8) (if equipped) to their
appropriate locations.
8. Open the radiator cap and fill the radiator completely
with coolant. Replace and tighten the radiator cap.
Add coolant to the overflow bottle until the bottle is 1/
4 to 1/2 full. This overfilling will compensate for any
air trapped in the cooling system.
9. Properly connect the battery.
10. 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.
11. Install the engine cover.
12. Install the belly pan.
13. Close and secure the engine cover.
14. Remove the Do Not Operate Tags from both the
ignition key switch and the steering wheel.
7.5 ENGINE ELECTRICAL SYSTEM
The engine electrical system, including the starter,
alternator and primary wiring, is described in Section 9,
“Electrical System.”
7.6 FUEL SYSTEM
7.6.1 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.
Note: 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.
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 must be reduced by
75 hours. The use of fuel with a sulfur content above
1.3 percent is not recommended.
