Start By:
Purge the air from the air tanks. Refer to Disassembly and Assembly, "Air Tanks (Brake) - Purge" for the Machine System.
Personal injury can result from removing hoses or fittings in a pressure system.Failure to relieve pressure can cause personal injury.Do not remove or disconnect hoses or fittings until all pressure in the air system has been relieved.
Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Note: Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will prevent dirt from entering the internal mechanism.
Position a suitable container below the radiator in order to contain the coolant for storage or for disposal. Drain the coolant from the radiator to a level below the air compressor. Refer to Operation and Maintenance Manual, "Cooling System Coolant (ELC) - Change".
