Regarding the hydraulics: My 504 with loader just acted like the pump was weak- one of the cylinders on the loader leaked a little, so I'd watch the level closely. There's a pipe plug on the left side of the transmission housing, about halfway down, that sure looked like a level plug (ie, fill til fluid comes out)- it even had been drilled and tapped with a 1/4 inch bolt, for easy checking. I finally broke down and got another pump, and when I took the old one out, got to looking and found that if the hydraulic oil level was at the level of the plug, it was just barely high enough to get into the pump! So apparently the pump was just starving for oil. I took some measurements, and now fill it to 8 inches below the filler on top of the tranny, and it works like a champ. So that plug on the side is not the fill level plug.
