65350A 1 Mercury CHECK VALVE ASSEMBLY, BLEED HOSE

Start By:
Prepare the machine for disassembly and assembly procedures. For additional information, refer to Disassembly and Assembly, "Preparation for Disassembly".Note: Put identification on all lines, hoses, wires, and tubes for installation purposes. Use caps and plugs on all lines, hoses, and tubes in order to prevent fluid loss or contamination of the systems.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publications Service Manuals, SENR3334, SENR5664, and NEDG5065 for the proper procedure, the proper equipment, and the proper tools needed in order to reclaim refrigerant from any Caterpillar equipment.
Personal injury can result from contact with refrigerant.Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.Personal injury or death can result from inhaling refrigerant through a lit cigarette.Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.
Evacuate the air conditioning system.Reference: Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134A Refrigerant"Reference: Special Publication, NEDG5065, "Air Conditioning Tools"
