To all...I have a 1951 TO-30 that I use primarily as a work tractor. I"ve owned it for about three years and have added a step-through trip-bucket loader and updated the paint and sheet metal. The farmer I bought it from said the engine had been rebuilt several years earlier (by a local JD dealership). Compression is good as is oil pressure. No oil in the radiator. I have a couple of issues I"d like to address with the tractor: 1) The oil pressure guage fluctuates wildly. Sometimes it reads a steady 20+ lbs, other times nothing. Do you think this is likely the guage (and not the oil pump)? It happens with the tractor running at any RPM. 2) Two years ago I replaced the pressure relief valve on the hydraulic pump - a local tractor parts/repair shop told me this would clear up the problem with the pump not maintaining pressure after the PTO was disengaged. It didn"t work. Does the pump need to be rebulit? 3) I have one annoying oil leak where the transfer case meets the engine (just behind the oil pan). Is this an engine seal leak or possibly a leak in the transmission? I"m assuming to find out (or even to fix it) the tractor would need to be split. 4) The valves seem rather noisy. More clackity-clack than I hear with the Ford/8n/2n/9n. Is this normal or should the valves be adjusted? If so, is adjusting the valves a very difficult process? I"m aware it"s overhead valve configuration. I"m no mechanic, but I"ve done all of the work on the tractor to this point and I"m not afraid to take things apart to fix something (that doesn"t require $20K in equipment, of course). Any advice is greatly appreciated. WMT
