Expansion (Orifice) Tube Replacement C60
Tools Required
• | J 26549-E Orifice
Tube Remover and Installer |
Removal Procedure
- Recover the refrigerant. Refer to
Refrigerant Recovery and Recharging
.
- Remove the grille. Refer to
Grille Replacement
in Exterior Trim.
- Remove the evaporator tube nut from the condenser (1). .
- Remove the evaporator tube from the condenser (1). .
- Remove the O-ring seal.
- Cap or plug the open line.
- 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:
7.1. | Remove as much of any impacted residue as possible. |
| Important: Do not overheat the pipe.
|
7.2. | 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. |
7.3. | While applying the heat, use the J 26549-E
in order to grip the expansion orifice tube. |
7.4. | Use a turning motion along with a push-pull motion in order to
loosen the impacted expansion (orifice) tube. |
Remove the tube.
Installation Procedure
- Use the J 26549-E
in order to install the expansion tube (3) into the condenser outlet
pipe (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. |
- Install the evaporator tube to the condenser.
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.
- Install the evaporator tube nut to the condenser.
Tighten
Tighten the nut to 20 N·m (15 lb ft).
- Install the grille. Refer to
Grille Replacement
in Exterior Trim.
- Evacuate and recharge the system. Refer to
Refrigerant Recovery and Recharging
.
- Leak test the fitting(s) of the repaired or reinstalled component
using the J 39400-A
.
