This is a procedure to service any cracks where the MTA tube attaches to the catalytic converter.
The following information is a supplement to TSB 83-3-30, MTA Tube to Catalytic Converter Inlet Pipe Bracket Breaks. Should services to the MTA tube bracket be required (per TSB 83-3-30), the air supply nipple weld to the converter should also be checked.
Figure 28:
If the air nipple weld is broken (Figure 28), the nipple should be rewelded to the converter shell. However, the following precautions must be observed:
1. Brazing is not authorized, because of high temperatures, 2. The converter shell metal and air supply nipple metal must be clean, dry and rust free.
3. Recommended welding rods for best welds are 308, or 309, or 310.
4. Assure that the air passageway into the converter is not blocked with weld, and that there are no gaps in the weld, and no converter shell "burn throughs".
5. Clean any weld splatter off the outside surface of the MTA air supply nipple to allow MTA tube to pass freely over the nipple.
