Expansion (Orifice) Tube Replacement C60

Tools Required

J 26549-E Orifice Tube Remove and Installer

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the grille. Refer to Air Inlet Grille Panel Replacement .



3. Disconnect the evaporator tube from the condenser (1). Refer to Evaporator Tube Replacement .
4. Remove the O-ring seal.
5. Cap or plug the open line.
6. Use the J 26549-E in order to remove the expansion (orifice) tube (3) from the condenser outlet pipe (2).

In the event of difficulty during the removal or a restricted or plugged expansion (orifice) tube, take the following steps:

6.1.	Remove as much of any impacted residue as possible.

Important: Do not overheat the pipe

6.2.	Carefully apply heat with a heat gun (hair drier, epoxy drier, or similar item) approximately 7 mm (0.25 in) from the dimples on the inlet pipe.

6.3.	While applying the heat, use the J 26549-E in order to grip the expansion orifice tube.

6.4.	Use a turning motion along with a push-pull motion in order to loosen the impacted expansion (orifice) tube.

Remove the tube.

1. Use the J 26549-E in order to install the expansion tube (3) into the condenser outlet pipe (2).
2. Install the new O-ring seal.

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

2.2.	Insert the short screen end of the new orifice into the evaporator tube.

3. Connect the evaporator tube to the condenser. Refer to Evaporator Tube Replacement .
4. Install the grille. Refer to Air Inlet Grille Panel Replacement .
5. Charge the system. Refer to Refrigerant Recovery and Recharging .
6. Inspect the system for leaks. Refer to Leak Testing .

Tools Required

J 26549-E Orifice Tube Remover and Installer

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the air cleaner assembly, if necessary.



3. Disconnect the evaporator tube (4) connection near the junction block (6).
4. Remove the O-ring seal (4).
5. Cap or plug the open line.
6. Use the J 26549-E in order to remove the orifice tube (1) from the evaporator tube.

1. Use the J 26549-E in order to install the orifice tube (1) into the evaporator tube (3).
2. Coat the new O-ring seal (4) with 525 viscosity refrigeration oil.
3. Install the new O-ring seal.

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.

4. Connect the evaporator tube connection (6).

Tighten
Tighten the tube connection to 24 N·m (18 lb ft).

5. Charge the system. Refer toRefrigerant Recovery and Recharging .
6. Inspect the system for leaks. Refer to Leak Testing .
