  • Engine/Tranny Case Sealant? Gasoila?

    I am getting ready to put my Panhead motor back together and wondered what to use on the inside of the engine and tranny cases as a sealant.

    I was told to use Gasoila Hard-Set red varnish sealant. I was going to pick up some tomorrow but thought I would ask you guys first. What is your experience, if any, with using this?

    I did search the forum for gasoila and only three hits came up, I know that Cotton stated gasoila isn't good for carb floats due to fuel, but does this apply to the cases considering it sees mostly oil?

    Thanks,

    Josh

      Glyptal is superior to Gasoila by far, but it must be pointed out that any contamination with modern digestive fuels can take either of them out. They do NOT resist P4gas.

      This is especially of concern to owners of H-D OHV's with leaky petcocks.

        I got six years out of Yamabond4 as a sealer for between the cases.

        Not bad, if only it was a Yamaha.

        H-D's (-80 OEM number) 3M #800 Industrial Sealer does much, much better, but it's ugly.

        Neither are appropriate for sealing the inside surfaces, encapsulating abrasives, etc.
        I have only found some epoxies and isocyanate urethane to survive fuel contamination.

          Nordbak industrial epoxy from Loctite will stand up to almost anything. It is expensive though, about $250 for a small kit that would do a few sets of cases.

            I use a product from the electric motor repair shops, it is called Dolph ER44 poleurethane sealer. It comes in a large spray can and a little goes a long ways, been using it for well over 20 years.

              Carl...after opening cases, which you used this product on, for an over haul, are you stating, the sealer held up and did not flake off anywhere ? Thanks, Paps

                  I have decided to go with the Glyptal, looks to be a bit better then the Gasoila, even though they both are not perfect.

                  I found the cheapest price for Glyptal to be $38.99/quart from Caswell, Ebay and Eastwood sell it for $49.99/quart. I never really dug into the electrical supply companies, so it may be found cheaper yet.

                  If you want to use the Gasoila, then V-Twin sells a 1/4 pint for an overcharged price of $36.31, or you can save money and buy it for $15.29 or better yet buy 1 pint for $34.16 from JME
                  http://www.jmesales.com This was local, so I ended my search with that.

                  As for the Dolph ER44 I only found their website, but didn't find any pricing.

                      Carl, is there any difference in ER44 and Dolph's ER-41 Polyurethane red insulator?

                        I've been using Glyptal for about 10 years, prior to that I used Gasoila. Both work well, but I like the Glyptcal much better. AS fopr the Gasoila, you must be absoluiteoy certain that ALL the oil is out of the casting before you apply it or the Gasoila will peal off. in small sheets.

                          Okay I am finally ready to seal my engine and transmission cases using Glyptal.

                          Reading the can it says an appropriate brush is needed to apply... but it doesn't say what is considered to be an appropriate brush????

                          It also says that when possible the coating should be baked for 2 hours at 125F. Is it necessary to do this?

                          I don't want to cut any corners on this so I am asking those who are far me experienced then I to lend in your advice.

                          Thanks,

                            Josh keep in mind a Harley tranny has no pressure due to the fact that it’s vented. You’re not working with the Columbia’s booster o rings here. What ever your choice of indestructible sealant your going to use there are certain guidelines to be followed. First is mating surface preparation. I use a white cotton cloth with lacquer thinner (Do not use paint thinner or others like it because they leave residue). I wipe those surfaces until that cloth remains white and the pores of the surface are oil free. Guaranteed no leak pans. Second is the amount of sealant. Lets keep in mind that the stuff your about to use is just that. Indestructible! Any extra than is needed could end up braking off inside and end up in a very important spot like an oil passage. Twenty years ago I came up with a simple way of dealing with this. I live out of a clip board. I save the cardboard backings. I apply sealant to one side of the gasket and smear it out against the card board and the other side the same way. This leaves the gasket surface saturated with no excess. Hope this helps. Bob L
