  • Tank Cleaning

    Has anyone had any luck with having a tank 'boiled', or whatever, at a radiator shop. I have a spare wing and header tank with very minor (rust?) flaking inside, usually around the threaded fittings. The rest of the interior of the tanks are just about spotless. Do I use the old 'BB' shaking trick to try and knock it out, or what. Can't find anything in old posts, if so please direct me to them. Thanks in advance!
    Cheers,
    Marty

    Marty, hi, I had a leaky tin tank in a '39 Bl65 that I took to the local radiator shop and they did a great job.

    I think that they cut out all the rust metal though.

      Dave,

      No leaks I am aware of, just want to clean some minor stuff out. Thanks, though.

        Speaking generally, what I would do if it were my tractor...

        A radiator shop, if they still have a hot tank (EPA); can get the goo and non-metalic stuff out. You can do the same with TSP and water, heated up to like 100f or more (put in sun in Arizona for a bit hotter), or use electric hot plate under wash tub full of solution.

        If Alum. Then use carb cleaner (the cold soak kind). I pour a gallon can into the tank and slosh it around, leave it in for a few days and rotate tank to get all areas under the solution. Wash out with soap and hot water, followed by a wash with solvent (paint thinner...)

        If you have light rust, you can often dissolve or at least neutralize it with buffered phosperic acid (Auto/Industrial paint store, home depot, Sherwin Williams).

        If you have much rust, then you need a place like redi-strip that uses a electrolytic process or you can do that yourself too; the car/old machinery people talk about it a lot on the web.

        You might find you have corrosion holes that were plugged up with a layer of old gas goo.

        Pay attention to the filler neck. Some are swedged in, some are welded. Some get loose. Check for leaks there before you install. Use a bit of airpressure and some soapy water. Dont use too much pressure or you will have funny metal balloon.

          Thanks Bob. The two headers look real clean after I scoped them last night. Just a few flakes of minor rust and a light discoloration that should come out real easy. I'm even hard-pressed to call them flakes, just very small pieces. May have come from around the fittings area. There are four on the header tank, alone. I will have to look at the wing tank tonight. Thanks for the tips!
          Cheers,
          Marty
