Check the level of the hyd fluid...also check the level of your engine oil, just might be going from the hyd pump into the crankcase...hope you understand what I mean...BobG in VA
You might try a Farmall specific group on line, maybe Yesterday's Tracrors or a Yahoo group. A repair manual might help as well. I had one like in the following link but sold it along with my M. Don't know whether it covers Super A or not. International Tractor Repair Manual A, B, C, MTA, H, M, MD, Cub, etc.
A manual made especially for the Super A might be easier to understand, if you can find one. For me, the more manuals from different authors, the better. One might cover something another skims over or tell a better way of doing it.
