Tools Required

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .



2. Loosen the nut from the evaporator tube fitting.
3. Use the J 26549-E in order to remove the orifice tube (1) from the evaporator tube (2).
4. Cap or plug the open line.

1. Uncap or unplug the evaporator tube.
2. Lubricate the new O-ring using new 525 viscosity refrigerant oil.



3. Install the new O-ring seal.
4. Install the orifice tube (1) to the evaporator tube (2).

4.1.	Coat the O-ring seal with 525 viscosity refrigerant oil.

4.2.	Insert the long screen end of the new orifice (1) into the evaporator tube (2).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

5. Connect the evaporator tube at the fitting.

Tighten
Tighten the fitting to 25 N·m (18 lb ft).

6. Evacuate and recharge the system. Refer to Refrigerant Recovery and Recharging .
7. Leak test the fittings of the repaired component using J 39400-A .
