Start By:a. remove hood assembly FLUID SPILLAGE CONTAINMENT Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "TOOLS AND SHOP PRODUCT GUIDE, NENG2500", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. In the following procedure, the counterweight has been removed for better photo illustration.
At operating temperature, the hydraulic oil is hot and under pressure. Hot oil can cause burns. To prevent possible personal injury, release the pressure in the implement hydraulic circuits (boom, stick and bucket) before any hydraulic lines or components are disconnected or removed.
1. Release the pressure in the hydraulic system as follows:a. Fully retract the rod in the stick cylinder.b. Adjust the position of the bucket so it will be flat on the ground when the boom is lowered.c. Lower the boom until the bucket is flat on the ground.d. Shut off the engine, and put the hydraulic activation control lever in the "Lock" position.e. Move the control levers for the boom, bucket, stick and swing through their full travel strokes. This will relieve any pressure that may be present in the pilot system.f. Slowly loosen the air breather cap on the hydraulic oil tank to release the pressure.g. Tighten the air breather cap on the hydraulic oil tank.h. The pressure in the hydraulic system has now been released. Lines and components can now be removed.2. Remove the fan assembly from the engine. See the topic "Remove & Install Fan Assembly" in this module.3. Drain the oil from the hydraulic oil tank into a suitable container for storage or disposal. The capacity of the hydraulic oil tank is 150 liters (40 U.S. gal).

At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure in the cooling system. Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
4. Drain the coolant from the cooling system into a suitable container for storage or disposal. The capacity of the cooling system is 31.5 liters (8.2 U.S. gal).5. Remove bolts (1), the washers and sheet assembly (3) from under the radiator.6. Loosen clamp (2), and disconnect lower radiator hose assembly (4) from under the radiator.

Remove bolt (12), the washer and nut from the end of the governor control cable assembly.10. Loosen nut (10) that holds the governor control cable assembly to bracket (13).11. Place a drain pan under the fuel system. A small amount of fuel will flow out of hose assemblies (9) and (11) when they are disconnected.12. Disconnect fuel hose assemblies (9) and (11). Put plugs in the ends of the to prevent fuel loss and to
