 B. Deburr the Tube and Remove the paint (if applicable).
 (1) The internal diameter:
 (a)
 Use the deburring tool and the stem subassembly that are correct for:

 -
the diameter of the tube,

 -
the thickness of the wall. (Ref. Fig. 213/TASK 20-23-11-991-004)

 (b)
 Make sure that the deburring tool is clean. Lubricate it with HYDRAULIC FLUIDS (Material No. 02-003).

 (c)
 Prepare to deburr the tube:

 -hold the tube,
 -push in the plunger of the tool,
 -put the stem into the end of the tube,
 -release the plunger to let the stem become expanded and seal the tube. (Ref. Fig. 214/TASK 20-23-11-991-005)

 (d)
 Deburr the tube:

 -continue to hold the tube,
 -apply light pressure on the cutter and at the same time turn the knurled body clockwise,
 -continue to turn until the tube is deburred.

 (e)
 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,
 -clean the end of the tube and the stem.

 (f)
 If the end of the tube is not correctly deburred:

 -push the tool into the tube,
 -do the step (d) again,
 -pull the tool out of the tube.

 (g)
 Fully clean the stem with CLEANING AGENTS (Material No. 11-003) if it touched the fluid and dry it immediately.

 (2) The external diameter:
 NOTE : Do not cause damage to the seals of the fittings:
____
 -
the tubes must not have external burrs,

 -
the tubes must go freely into the fittings.
 If a tube does not go freely into a fitting (not circular, out
 of tolerance), do not install the fitting.

 (a) Remove the burrs on the external diameter of the tube with Grade 240 emery cloth. Burrs on the external diameter of the tube can cause damage to the seals in the fittings. This damage can cause external leakage. The surfaces must be clean and without damage:
 -the swaging area must have no deep scratches and must be clean (no dust, particles of metal, etc.). Before you swage, clean the end of the tube with CLEANING AGENTS (Material No. 11-003). You can do the installation on parts that are treated with Alodine. You must not do the installation on parts that are painted.
 (3) Remove the paint (if applicable)
 (a)
 Remove the paint, with Grade 400 emery cloth, on a sufficient length so that you swage the union on a bare area. Make sure that you do not make scratches on the tubes when you remove the paint.

 (b)
 make sure that all the tube ends are in the correct condition and agree with the tube dimension specifications (Ref. TASK 20-23-11-200-001).

 (c)
 Clean all the tube ends with CLEANING AGENTS (Material No. 11-003).

 C. Mark the Tube Insertion
 (1) Make the marks for tube insertion.
 NOTE : These marks give an indication of the depth of the tube in the
____
 fitting before and after swaging.

 (2)
 Use a marking tool with the correct dimensions for the tube that you must swage: DLT5302-013-01, tubes from 1/4" thru 3/8" DLT5302-031-01, tubes from 1/2" thru 3/4" DLT5302-040-01, tubes from 1" thru 1-1/2"

 (3)
 Put the marking tool in position on the tube. The lip of the marking tool must be against the end of the tube. Make a mark on the tube with the marking pen D10058. (Ref. Fig. 215/TASK 20-23-11-991-006)
