ISSUE:
A new air conditioning spring lock coupling cleaning procedure has been developed. This procedure is required for a thicker O-ring that has been
released for servicing spring lock couplings. These O-rings have a larger cross-sectional diameter for improved sealing. The thicker O-ring is green in
color and identifiable only by the part number. These are service only O-rings and will not be used in production.
ACTION:
Clean the Spring Lock Coupling(s) (SLC), if their service is required, and install the new thicker O-rings by referring to the following Service Procedure
for details.
SERVICE PROCEDURE
