MAINTENANCE MANUAL
Repair Method: You need to replace a damqged BACu24AB swage union. You will cut out the fitting and replace it with a BACS13BX or BACS13AP sleeve, a coupling nut and MS21924 flareless bulkhead union of the same or equivalent material as the union you are replacing. Check Fig. 802 for sleeve/tube material limitations.
To make the repair (Refer to Fig. 807):
Step 1: Cut the tube adjacent to the damaged union - to dimension A, B, or C depending on the sleeve and sleeve installation method you plane to use.
Step 2: Slide a flareless coupling nut on the tube. Follow the procedures for presetting a BACS13AP sleeve or swaging a BSCS13BX sleeve to the tube end.
