15. Connect the fuel inlet line to the fuel filter head.
16. Connect the fuel return line to the fuel filter head.
17. Connect all the labeled wire harness connections on
the engine.
18. Install the hood latch plate. Align the mark on the
plate to help with hood adjustment.
19. Secure the return hydraulic oil filter plate to the
frame.
20. Install both heater hoses to the engine and tighten
clamps.
21. Install the complete radiator assembly (1) and
tighten the four bolts
22. Install the hose clamp on the bottom radiator hose
and work onto the engine. Tighten the clamp.
23. Install the hose clamp on the top radiator hose and
work onto the engine. Tighten the clamp.
24. Connect the transmission inlet and outlet hoses on
the oil cooler (2). Install the clamp holding the top
transmission cooler hose and the three bolts holding
the fan screen.
25. Install and adjust the engine cover.
26. Connect the negative (-) battery cable to the battery
negative terminal.
27. 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. 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.
28. Check that all hydraulic system, electrical system,
cooling system, fuel system, and exhaust system
connections are correct and connected tightly
29. From within the cab, lightly depress the throttle pedal
to full-throttle position. As needed, adjust the limit-
stop screw until it touches the pedal. Tighten the
locknut to 13,6-14,1 Nm (120-125 lb-in).
Note: Have an assistant stand by with a Class B fire
extinguisher.
30. Run engine to normal operating temperature then shut
off the engine. While the engine is cooling, check for
leaks.
31. Allow the engine to cool. Check the radiator coolant
level, and top off with a 50/50 mixture of ethylene
glycol and water. Replace the radiator cap.
32. Check for leaks from the engine, main hydraulic pump
and lines, transmission, hydraulic reservoir and fuel
tank. Check the levels of all fluids and lubricants. Fill
as required.
IMPORTANT: During the full throttle check:
• DO NOT operate any hydraulic function.
• DO NOT steer or apply any pressure to the steer-
ing wheel.
• Keep the transmission in NEUTRAL (N).
33. Obtain and connect an appropriate engine analyzer
or tachometer. Check the engine rpm at full throttle.
If the rpm is not 2200 +/- 50 rpm, readjust the throttle
limit-stop screw at the throttle pedal within the cab.
34. Purge the hydraulic system of air by operating all
boom functions through their entire range of motion
several times. Check the hydraulic oil level.
35. Check for proper operation of all components.
36. Turn the engine OFF.
37. Install the engine belly pan.
38. Close and secure the engine cover.
