The most common issue is a warped pump cover. This happens over time, and is a known issue. The bearings can contribute to the issue, but if it is a good runner, I would do the pump cover and see how that affects the pressure. The process is to remove the oil pan. then remove the oil pump (easy to do, and obvious) remove the lower cover (not iron) and flat sand it on a piece of glass with 340 grit paper and thin oil, or water. Use non directional motion and uniform pressure to bring it back to flat. Next use 600 grit to smooth it a bit more. The clearance between the rotor gears, and the cover (with the paper thin gaskets should be between .0005", and .001". Plastigauge can be used to measure this, or thin .0005, and .001 shim stock. Put a small tab of the stock between the cover, and a gear. Gently tighten it (with gasket) until with a .001 tab it begins to lock (do not force tightness) and with a .0005 tab of shim it turns free when snug. The gaskets can be found at caseih dealer, or made from material (very thin material) the stack or combo of gaskets act as shims to provide the clearance. All this costs is a pan gasket, and some pump gaskets and time. Best of luck, Jim

Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens. In the winter, we'd play
