  1. The purpose of the resistor is to protect the tractor wiring in case of a failure in the circuit between the alternator output stud and the battery terminal on the starter solenoid. If that wire fails the entire amperage of the alternator will go out the #1 terminal back to the ignition switch. The wiring and switch would not last long if it had 70 amps flowing through it. Applying full battery voltage to the #1 terminal will not cause any problem. That terminal receives full charging voltage through the diode trio in the alternator. It is also connected through one of the brushes to the stator. The regulator controls the voltage output by varying the ground the other brush

    Re-ring 282

    The block serial number for the different sleeves is 71777 / 71778. The later engines have the press fit sleeves. If you re-ring with the original type chrome faced rings you will need to break them in under as close to full load as you can get or you may end up with more blowby than you have now. Chrome faced rings last a lot longer but for your application I would opt for moly faced cast rings. Not as long lasting but will seat very quickly.
  3. Search for C-153 on the parts web site.
  4. I think I'll take a chance that the 4 pair I have been using for the past 40 years are not on the recall list. They are to old to have a SKU number.
  5. The '40 crank will fit in the 450 but you need to use bearings for the '40 M. The size of the bore in the block is the same for the M through the 450. The early crankshafts used thicker bearing shells.
  6. No point in making sure the countershaft night is tightened to 300 ft/lbs. The gears are a loose fit on the shaft so as you start to use the tractor the pressure on the gears will cause them to move so they and the spacers will wear causing the nut to become loose. Changes over the life of that transmission system to combat the problem of the nut coming loose included a heavier counter shaft, a left hand threaded countershaft, a thicker nut, thicker walled spacers, and a thrust washer on the front of the shaft. None of these solved the problem, only slowed down the time it took to become loose.
  7. Had my right knee replaced 11/11/19. My wife had a heart attack twos weeks later so that is when I started driving. Went back to work half time after Christmas and full time February 1.
  8. I worked for an IH dealership from 75 to 85. Saw that tool in the tool room but never knew what it was for.
  9. Sioux Falls, SD and Worthington, MN plants combined butcher about 40,000 hogs per day. Both of them are currently closed.

    When you change from the original block on the cylinder rod end to the ball joint style the cylinder rod is the same but the cylinder barrel has the trunnions mounted in a different location. If you don't change the barrel the tractor will not steer all the way in one direction.
  11. A 10DN alternator will not work with with the original generator regulator. The generator sends voltage out through the F terminal where the regulator controls the generator output by grounding the field current. The 10DN regulator work by providing voltage to the F terminal where it is grounded internally in the alternator.
  12. The cheap meters are the ones that have the problem.
  13. Mechanical voltage regulators work by switching between maximum charging and no charging. They react much slower than transistor regulators and as a result sometimes do not play well with digital VOMs. Analog meters cannot react quick enough the show the changes in voltage so the resulting reading shows a steady reading. Your digital meter is constantly displaying the voltage it sees when it refreshes the display.
  14. I'd say it is a mechanics service tool for automotive repair, probably from the 1930's.
