Bought it last year. Did some work to it. Put 100 hours on it replacing the drain tile around our house. Started it half a dozen times over the winter. No problems, other than 2 more cylinders leaking and king pins are still shot. I've put maybe 10 hours on it so far this summer, always check fluids before using, and often after too.
Last week I checked everything, all good, and used it to load some dirt into the truck, ran for about 45 minutes. After I parked it and got out, I noticed an oil trail the last 50 feet into where I parked it. Looked it over and checked the oil, and the dipstick was full. It was thin and clean (I did just change the oil again this spring). Since the only choices are Fuel and Antifreeze, I assume the pump was leaking fuel into the crankcase. I'll pull the plug to check for water when I get a chance. Injectors were new when I bought it last year.
Was this a common problem for the 580c engine, I believe it is the 207 if I remember correctly? I don't remember any other coolers or anything that could pass hydraulic oil or transmission oil to the engine. Would the shaft seals mentioned in the manual be the problem, or would this require a pump teardown? I've taken apart a few pumps, but never tried putting any back together. Is a pump rebuild something worth trying myself? I was ASE Master Certified for Med/Heavy Trucks, but not equipment and we always farmed out our pump rebuilds. I've rebuilt many components, starters, alternators, transmissions, axles, engines, cylinders, pumps, turbos, etc. so I'm the complexity isn't a problem. However, I don't have any special tools that might be needed, or any special test equipment, which is the same reason I haven't rebuilt any auto trannys since I quit working on trucks full time.
What do you think? I suppose I could take it off and take it in to get tested. I bought a skid steer this spring, and the plan was to sell the backhoe this fall after I was done with it, but I can't sell a backhoe producing oil.
