I have a 1952 8N that runs very well. Previous owner did n in frame overhaul.Engine has excellent compression and good power. The only issue with this tractor is the low oil pressure. I have read all the posts, and done all the checks that I possibly could do. I replaced the Rotella 15-40 with sraight 40 wt. I have replaced the gauge with a stewart warner, and I have replaced the oil pressure relief valve and spring. All this has made no difference! 20 to 25 lbs cold and barely above 0 hot at idle. If I raise the idle I can sometimes get it to between 5 to 8 lbs. I'm at a loss....
What about stretching the relief valve spring,or replacing the oil pump gears ?
Any ideas ????
