 (n) Remove the nut (1). Make sure that the slide (4) and the coupling (3) are between 3.8 mm (0.1496 in.) and 0 mm (0.0000 in.) from the shoulder of the union. If not, tighten the nut (1) until the slide (4) and the coupling (3) are in the correct position.
 (o) The union (2) must touch the tape (5).
 (p) The edge of the coupling (3) must be across the mark on the tube.
R  (q) Tighten the assembly to complete the swaging procedure.

R  (b) For the Yellow system: 
R  - upstream of the engine pump (Ref. TASK 29-00-00-870-004) 
R  - upstream of the PTU (Ref. TASK 29-00-00-870-005) 
R  - upstream of the Yellow E-pump (Ref. TASK 29-00-00-870-006) 
R  - downstream of the engine pump (Ref. TASK 29-00-00-870-007). 
R  (c) For the Blue sytem: 
R  - upstream of the Blue E-pump (Ref. TASK 29-00-00-870-008) 
R  - downstream of the Blue E-pump (Ref. TASK 29-00-00-870-009). 
R  (d) For the normal braking system (Ref. TASK 32-42-00-870-001). 
R  (e) For the alternate braking system. 
R  - low pressure (Ref. TASK 32-43-00-612-001) 
R  - high pressure (Ref. TASK 32-43-00-870-002). 
R  (6) Make sure that the work area is clean and clear of tool(s) and other
 items.
