Expansion (Orifice) Tube

Tool Required:
J 26549-E Orifice Tube Remover and Installer or Equivalent

Remove or Disconnect
1. Recover refrigerant.
2. Grille.
3. Evaporator tube from condenser. (See the bottom of this article).
4. O-ring seal.
- Cap or plug the open line.
5. Expansion (orifice) tube from the condenser outlet pipe, using J 26549-E or equivalent.
- In the event that difficulty is encountered during the removal of a restricted or plugged expansion (orifice) tube, the following procedure is recommended:
A Remove as much of any impacted residue as possible.
B. Carefully apply heat with heat gun (hair drier, epoxy drier or equivalent) approximately 7 mm (1/4 inch) from dimples on inlet pipe. Do not overheat pipe.
C. While applying heat, use expansion tube removal tools J 26549-E or equivalent to grip the expansion (orifice) tube. Use a turning motion along with a push-pull motion to loosen the impacted expansion (orifice) tube and remove it.
