    Repairing Damaged Expansion Chamber

    Hi

    Expansion Chamber of my Yamaha RX 135 is damaged from bottom. though its not a very big dent then too, its affecting performance.

    please let me know safe ideas to rectify this problem.
    chamber is made up of tin not steel. please let me know if you know anyone who make or repair chambers in Mumbai Suburbs/ New Mumbai/ Thane.

    waiting for suggestions.

    Thanks.

    Topic Approved.

    You may have to make some inquiries at the local Automobile market of your city. I don't mean the company owned showrooms, but automobile parts shops.

      Any body repair shop should be able to handle that. They normally weld / braze spokes on the dented area, heat the metal up and pull on the spokes with a plier.

      There are various other methods but I wont recommend them in India.

          Seal the one end with auto-freeze plug/M-seal fill entirely with water and seal the other end.Now put the filled expansion chamber in the freezer and when the water starts to freeze it will push out the dent.Welding/brazing tin is not a thing your local welder will effectively be able to do.

            He will need a big freezer I guess

              He can approach a local ice-cream parlour/ice factory to get a big one.Or the fix can be used as an excuse to head to Europe/the Himalayas.

                thanks Vignesh and Gyroerror,
                that was an idea which i was planning, but according to some sites and forum, freezing method is having unpredictable results.

                some says to fill chamber 70%, some says 80-90. but no one is sure about the result. as my chamber is made up of tin, its tensile strenghth is very low. so i am afraid of cracking.
