Install a Welded Catalytic Converter
Catalytic converters filter a percentage of harmful emissions that a motorcar produces. Environmental regulations dictate emission contraction methods that Everyone nation must pursue. Automakers append this type of emission control Accoutrement on late van and Motor lorry products. However when method surpasses the limits of the converter's expertise to function properly, it becomes binding to transform it to preserve the alike flat of filtration as when the converter was contemporary. When elderly catalytic converters persist in manipulate after their activity expectancy, the vehicle can fail tests of emission containment. It is facile to install a current welded catalytic converter with some public shop tools.
Instructions
Compare that distance to the length of the fresh converter and adjust so that a Correct connexion Testament be prepared between the contemporary converter and the ancient exhaust piping.2. Move the cutting torch tanks near enough to the work area for the cutting head to reach the converter and operate freely.1. Raise the vehivle to a heighth where you keep inconsiderable access to the exhaust development of the vehicle. Evaluation for fluid leaks and be undeniable that the nature sorrounding the catalytic converter is dry and free of charge of fuels that may be ignited during the cutting gone of the ancient converter(s). Speck the exhaust piping 3" before and after the converter, where the exhaust pipe is at its straightest and crowing case.
Open the gas and air valves at the top of each tank and grab the igniter. Open the valves on the cutting handle in the proper proportion to turn the cutting flame from a flapping yellow to an intense, clear blue gas flame that can cut through metals. Press the air injection tab to create a cutting flame that can cut out the old converter quickly and easily. Cut around the marks made on the exhaust pipes outside of the converter inlet and outlet.
3. Grind down and around the end of the exposed exhaust pipes with a handheld grinder and abrasive wheel. Depending on whether the new converter has expanded pipe ends that slide over the old exhaust pipes or not, the converter will need to be tack welded end to end using a stick welder. Prepare the ends of both exhaust and converter for welding. A welded catalytic converter is expected to have high performance throughout the life of the vehicle. Take time to get this step right before welding so that you'll get a better result.
4. Connect the ground to the exhaust pipe that will be welded and hold the new converter in place, edge to edge with the old exhaust piping. Protect your eyes with welding glasses and touch the stick to the joint of the two parts. After the connection is made, hold in place for three seconds, then pull away. Repeat this process again on the opposite side of the piping and then on the other end of the converter. This tack weld will hold the pieces together for complete welding later. Complete the converter welding around both inlet and outlet pipes of the converter so that the weld is complete and free of leaks.
5. Transfer old converters and exhaust tubing that can be recycled into a recycling bin. While the converter may become clogged and unable to be used, the precious metal can be recycled. After each and every upgrade or maintenance job there is something you can do to help the environment. Do your part by recycling everything that needs to be disposed of properly and find that your shop stays clear of dangerous debris.
