Start By:a. remove hoodb. drain coolantc. drain hydraulic tankd. evacuate air conditioning systeme. remove radiator guard Fluid Spillage ContainmentCare 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 Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates.
Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publication SENR3334-01, SENR5664 and NEDG5065-01 for the proper procedure, equipment and tools to reclaim refrigerant from any Caterpillar machine.
Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping refrigerant R-12 (C C12F2Dichloro Difluoro Methane) and refrigerant R-134A can cause freezing of human flesh.Do not smoke while working on air conditioning. Inhaling Refrigerant R-12 or R-134A through any smoking material, although not toxic or flammable, can cause violent illness. Also heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual Form No. SENR3334-01 and SENR5664, for more information on removal and installation of lines and refrigerant from the system.
At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot water or steam. Any contact can cause severe burns. Look at the sight gauge to check the coolant level. The coolant level should be in the green range. If necessary, remove the fill cap only after the engine has been stopped and the cap is cool enough to remove with your bare hand. Remove the cooling system fill cap slowly to relieve pressure. Cooling system condition contains alkali that can cause personal injury. Avoid contact with the skin and eyes and do not drink.Allow cooling system components to cool before draining.
Typical Example1. Disconnect air conditioning condenser lines (1).
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the fill plug only when the engine is stopped and the fill plug is cool enough to touch with your bare hand.
2. Disconnect hydraulic oil cooler line (2).
Typical Example3. Disconnect fan motor hydraulic hose (3) at motor and at fitting behind rear frame member. 4. Remove upper radiator brackets (4) consisting of four bolts and washers. Loosen hose clamps and slide top radiator hose forward. 5. Remove bottom radiator housing bolts and washers (5) and allow housing to hang from hose. Replace gasket during assembly. 6. Remove four bolts and washers and remove step plate (6). Open rear compartment lid. Remove six bolts and washers securing cover plate (7). Remove the cotter pin from the control arm. The cotter pin is located behind the rear compartment. 7. Remove four bolts and washers and remove step plate (battery box cover) (8). 8.
