Farmall Cub

All 3 of my Cubs have the overflow tube broken off and this may not be a correct police type fix it certainly worked and can be done with the hood on.Drilled a 9/64 hole in a 1/4 inch bolt and a jam nut on the outside of the neck.The bolt fits right in the broken tube and the threads help hold the tube in place.

Just in case you are a butterfingers like I can be occassionally, you might want to slip a shop rag in the radiator opening just enough to keep a stray bolt from slipping from your fingers and falling in. Naturally you will want to remove the rag once the bolt is tightened.

To eliminate possible galvanic corrision and seizure of the nut to the bolt, I suggest using a brass bolt and a brass nut.
