The old girl just won't quit. We bought this tractor back in the Hodgins auction days for cheap. It was our main tractor for yrs and yrs. It has been looked after mechanically by me since we owned it. I have adjusted injector and valve lash and replaced O-rings on injectors just because I figured it was worth it at the time 25 some odd yrs ago. We had to replace the clutch at time of purchase which was I did and changed 2 wheel seals and bearings over the many years. Upon removing the planetary covers I saw a sun gear had hairline cracks and wear. I don't think the previous owner was regular with gear oil changes. Anyway I replaced all 4 sun gears to be preventative at the time and they were ridiculous cheap back then $140 if I remember correctly. I swapped planetaries to the other side to run on fresh side of gears. I sent an engine oil sample away at the time and it came back in good health. Many thousand hrs later I notice the old girl when running at operating temp, if you cut the throttle back it will trip the murphy switch low oil pressure. Bearings are likely in need. Western diesel just called and they are in. Under $400 with a pan gasket as well. Cheap maintenance. In all these yrs the only other work done was a new hydraulic pump for $1100, a new exhaust for $1200 and a water pump. A couple 3 solenoids and odd light wiring things. Replaced centre pin bushings once as well. This was far from a new tractor when we got it and just keeps going everytime you ask it too. Never touched the tranny or the diffs or rads etc. These things were built to withstand the test of time. We use this tractor on heavy harrows and 33' sunflower disc. On the scraper as well. Will pull like crazy down low and can run cheap. It will work in the field on a tank of fuel longer than I can. Put a FM 750 in it yrs ago and a Gleaner combine seat and its a comfy tractor to operate. Not the best a cab quietness but not terrible either considering it's a 1981!!
