My Farmall Super M Oil filler cap mounting bolt broke down inside the hole. That bolt goes into part of the casting, which I found out is not very thick. There is also a metal with holes in it down in there to filter out large objects I guess. Anyhow, I was tightening the cap and the whole bolt and that piece of cast iron came out. So, now there is no way to attach the filler cap.
I have a feeling this has happened to other people considering how thin that part of the casting is. Changing that whole piece is not an option. It's like a fairly large part of the engine and looks like a lot of work to change, not to mention finding the part and the cost. At the same time I can't leave it like this or rain water will get in the engine.
I could possibly ask a local welder to weld something but that seems very difficult to weld in that hole and plus it's cast iron, which is hard to weld anyhow, not to mention the flammable oil. Plus I'd have to drive the tractor about 6 miles to a welder. On top of that, I could see welding "spray" would get into the engine. So, it looks like welding is not an option, and neighter is JB Weld because everything is coated with oil.
Unless someone has another idea, all I can think of is finding another method to seal the filler hole. The only idea I can think of would be those expandable rubber plugs like they use on boats, where you tighten a wingnut and the rubber expands. But can I find one to fit this size hole? Plus, will the rubber hold up under the heat of the engine?
Anyone have any ideas or suggestions? Anyone had this problem? I do need to seal it against weather because the tractor sits outside. I guess that's why I broke it, I always tightened it very tight to keep out water.
Thanks
