J 26549-E Orifice Tube Remover and Installer

1. Recover the refrigerant from the system. Refer to Refrigerant Recovery and Recharging .
2. Remove the retainer from the evaporator case to the evaporator tube.
3. Remove the evaporator tube from the evaporator.



4. Use the J 26549-E in order to remove the expansion (orifice) tube (1).
5. Remove the restricted or plugged expansion tube:

•	Remove as much of the impacted residue as possible.

•	Carefully apply heat with a heat gun, or hair dryer 7 mm (0.25 inch) from the dimples on the inlet pipe.

•	DO NOT overheat the pipe.

•	While applying heat, use the J 26549-E in order to grip the expansion tube. Use a turning motion along with a push-pull motion to loosen the impacted expansion tube and remove.

Important: 

•	Install the shorter screen end (3) first into the evaporator.

•	Coat the O-ring seal (2) with 525 viscosity refrigerant oil.

1. Use the J 26549-E in order to install the expansion tube.

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.

2. Install the evaporator tube to the evaporator.

Tighten
Tighten the evaporator tube to 19 N·m (14 lb ft).

3. Install the retainer to the evaporator tube to the evaporator cover.
4. Evacuate and Recharge the refrigerant to the system. Refer to Refrigerant Recovery and Recharging .
5. Inspect the system for leaks. Refer to Leak Testing .
