#### Tool Required

J 29803-A ISO Flaring Tool

### Removal Procedure

1. Obtain the recommended tubing and steel fitting nuts of the correct size. Use the outside diameter of the tubing to specify the size.
2. Cut the tubing to length. Use a string to measure the old pipe and add 3 mm (1/8 in) to determine the correct length for each ISO flare.
3. Cut the end square
4. Use a de-burring tool to chamfer inside and outside diameter of the tubing.
5. Remove all traces of lubricant and/or metal chips from the tubing.
6. Ensure the fittings are installed on the tubing before starting the flare.
7. Clamp the flaring tool body (2) in a vise.
8. Select the correct size collet and forming mandrel for the tube size used.
9. Insert the proper forming mandrel (1) into the tool body.
10. Thread in the forcing screw (3) until contact is made with the forming mandrel (1) while holding the mandrel (1) in place with your finger.
11. Turn the forcing screw back one complete turn when contact is made.
12. Slide the clamping nut (1) over the tubing into the correct collet. Leave approximately 19 mm (3/4 in) of tubing extending out the collet.
13. Insert the assembly into the tool body. The tube end must contact the face of the forming mandrel.
14. Tighten the clamping nut into the tool body very tight or the tube may push out.
15. Wrench tighten until the forcing screw bottoms out. Do not overtighten the forcing screw or the flare may become over-sized.
16. Back the clamping nut (1) out of the tool body.
17. Disassemble the clamping nut (1) and collet (2).

Notice: When replacing tubing, make sure that the tubing is free of burrs, cuttings, and dirt. While wearing safety glasses, use compressed air to blow out contaminants. Contaminants can destroy the air brake valve sealants.

18. The flare is now ready for use.
19. Use a tube bender to bend the new pipe to match the old pipe.
20. Ensure to maintain the following clearances:

• | Maintain the minimum clearance of 19 mm (3/4 in) to all moving components.

• | Maintain the minimum clearance of 13 mm (1/2 in) to all vibrating components.

• | Maintain the minimum clearance of 7 mm (1/4 in) to any shielded lines, unless clipped to a component.
