-when you get the set swage torque values (after 15 to 20 seconds), the motor stops, the mandrels turns counterclockwise then moves to the rear,
-
the expander moves to the rear,
-
the cycle is completed.
(8)
Put the jaw switch on RELEASE.
(9)
Open the half jaws and remove the tube from the swage tool.
(10) Carefully clean the tube with CLEANING AGENTS (Material No. 11-003).

D. Do the Check of the Swage
(1) Measure the diameter A, B and C and make sure that they obey the dimension acceptance criteria. (Ref. Fig. 254/TASK 20-23-11-991-047, 255/TASK 20-23-11-991-048)
NOTE : You must calculate the permitted min. and max. dia. C as a
____ function of the actual thickness of the tube before swaging.
NOTE : In all cases, you cannot re-swage.
____
(2)
Make sure that there are no scratches or other damage on the seal areas between sleeve and union.
(3)
Make sure that there are no scratches or roller marks on the tube
I.D.
NOTE : A helical extrusion mark in the G area (due to tube wall
____ growth during swaging) or a rubbing mark in the H area (due to swage tool cage rubbing) is permitted.
(4) Connect the HARRISON sleeve and union of the tubes and TORQUE it to the normal test value.

-
upstream of the Yellow E-pump (Ref. TASK 29-00-00-870-006)
-downstream of the engine pump (Ref. TASK 29-00-00-870-007).
(c)
For the Blue sytem:
-upstream of the Blue E-pump (Ref. TASK 29-00-00-870-008)

(d)
For the normal braking system (Ref. TASK 32-42-00-870-001).
(e)
For the alternate braking system.
-low pressure (Ref. TASK 32-43-00-612-001)
-high pressure (Ref. TASK 32-43-00-870-002).
(6)
Make sure that the work area is clean and clear of tool(s) and other items.
