A. Selection of the Tools to Cut and Deburr the Tube
   (1) Get the applicable tube cutter.
NOTE: The RCSK8-02S013 RYNGLOK UNIVERSAL TOOL KIT, and Permaswage DLTFRPSKT3028A REPAIR KIT FIELD - SIZE 04 TO 24 include tube cutting and deburring tools and their related swaging kits, and are approved by Airbus.
As an alternative, you can use other tools (hacksaw or automatic cutting tool) if these tools
  • make a clean cut
  • do not cause tube contamination (filings, chips...).
     (a) For tube size -04 or -06
  • Permaswage tool P/N: D12530-001
  • Rynglok Eaton Aeroquip tool P/N: RTCT0-01-01
     (b) For tube size -08 or -10 or -12
  • Permaswage tool P/N: D12531-001
  • Rynglok Eaton Aeroquip tool P/N: RTCT0-01-02
     (c) For tube size -16 or -20 or -24
  • Permaswage tool P/N: D12532-001
  • Rynglok Eaton Aeroquip tool P/N: RTCT0-01-03
   (2) Get the applicable inner deburring tool.
     (a) For tube size -04 or -06
  • Permaswage tool P/N: D9851
  • Eaton Aeroquip tool P/N: RDTA0-01-01
     (b) For tube size -08 or -10 or -12
  • Permaswage tool P/N: D9850
  • Rynglok Eaton Aeroquip tool P/N: RDTA0-01-02
     (c) For tube size -16 or -20 or -24
  • Rynglok Eaton Aeroquip tool P/N: RDTA0-01-03
   (3) For tube size -16 and -20 only, get the applicable outer deburring tool.
  • Rynglok Eaton Aeroquip tool P/N: RDTA0-01-06
   (4) Get the applicable stem.
4. Procedure
Subtask 20-23-11-917-112-A
A. Cutting the Tube
   (1) Put the tube cutter in the correct position on the tube:
     (a) Install the tube cutter on the tube.
     (b) Make the tube touch the two rollers of the tube cutter.
     (c) Tighten the drive screw until the cutter wheel lightly touches the tube.
   (2) Give the drive screw a 1/16 to 1/8 turn.
   (3) Turn the ratchet handle through the arc of clearance until the wheel makes one or two turns.
   (4) Make sure that the wheel makes only one groove:
CAUTION: MAKE SURE AT REGULAR INTERVALS THAT THE CUTTER WHEEL STAYS IN THE SAME GROOVE ON THE TUBE.
     (a) If the wheel makes only one groove, do steps (2) and (3) again to cut the tube.
     (b) If the wheel makes more than one groove (thread) on the tube, remove the tube cutter. Do the procedure again from step (1) on a new area of the tube to remove the thread.
   (5) Cut the tube slowly and smoothly to make sure that the shape of the end of the tube does not change.
   (6) Regularly lubricate the ratchet, the rollers and the cutter wheel with Mineral base Lubricating Oil-General & Water-displacing Preservative Low Temp. - (Material No.03BDB9) for easy operation.
NOTE: After you do steps (2) and (3) two or three times, you can give the drive screw a 1/8 to 1/4 turn in step (2) to let you do the procedure faster.

B. Deburring the Tube
   (1) Deburr the internal diameter.
     (a) Make sure that the inner deburring tool is clean. Lubricate it with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) or Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
     (b) Hold the tube.
     (c) Push in the plunger of the internal deburring tool.
     (d) Put the stem into the end of the tube.
     (e) Release the plunger to let the stem expand and seal the tube.
     (f) Apply a light pressure on the cutter and at the same time turn the knurled body.
     (g) Continue to turn the knurled body until the internal diameter of the tube is deburred.
     (h) Do not push the plunger in, but carefully and slowly pull the deburring tool from the tube until you can see the first ridge of the stem.
     (i) Make sure that the tube is correctly deburred:
       1 If the end of the tube is not correctly deburred, do step (c) to step (h) again.
       2 If the end of the tube is correctly deburred, pull the tool out of the tube.
     (j) Fully clean the stem and the end of the tube with a Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) and dry it immediately.
   (2) Deburr the external diameter of tube sizes -04 to -12 and -24:
CAUTION: DO NOT LET BURRS OCCUR ON THE EXTERNAL DIAMETER OF THE HYDRAULIC TUBE. SUCH BURRS CAN CAUSE DAMAGE TO THE SEAL OF THE FITTING. THIS DAMAGE CAN CAUSE LEAKAGE.
     (a) Remove the burrs on the external diameter of the tube with CLOTH-EMERY (GRADE 240).
     (b) Clean the end of the tube with Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) . The surface must be clean and without damage.
     (c) The tube must go freely into the fitting. If the tube does not go freely into the fitting, do not install the fitting.
   (3) Deburr the external diameter of the tube sizes -16 and -20:
CAUTION: DO NOT LET BURRS OCCUR ON THE EXTERNAL DIAMETER OF THE HYDRAULIC TUBE. SUCH BURRS CAN CAUSE DAMAGE TO THE SEAL OF THE FITTING. THIS DAMAGE CAN CAUSE LEAKAGE.
     (a) Make sure that the outer deburring tool is clean. Lubricate it with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) or Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
     (b) Hold the tube.
     (c) Push in the plunger of the outer deburring tool.
     (d) Put the stem into the end of the tube.
     (e) Release the plunger to let the stem expand and seal the tube.
     (f) Apply a light pressure on the cutter and at the same time turn the knurled body.
     (g) Continue to turn the knurled body until the external diameter of the tube is deburred.
     (h) Do not push the plunger in, but carefully and slowly pull the deburring tool from the tube until you can see the first ridge of the stem.
     (i) Make sure that the tube is correctly deburred:
       1 If the end of the tube is not correctly deburred, do step (c) to step (h) again.
  • The tube must not have external burrs.
       2 If the end of the tube is correctly deburred, pull the tool out of the tube
     (j) Fully clean the stem and the end of the tube with Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) and dry it immediately.
     (k) The tube must go freely into the fitting. If the tube does not go freely into the fitting, do not install the fitting.
