If you have a 440ICD there should be two pedals, one on each side of the console. The one on the right side is the brake pedal and the one on the left side is the clutch pedal. The two levers in the middle operate individual steering clutches and each side brakes separately. If your machine is equip...

Scott When I bought my 440ICD/831 the air cleaner was missing. After searching around for a while one diesel shop suggested to me that I should look into a throw away filter. I am running a Baldwin PA2803. It is a pleated paper filter about 8" in diameter and about 10' long. Came complete with a met...

Pull the valve cover off and see if an exhaust valve has dropped down? I keep thinking of all those gears on the back of the engine. Possibly pull the governor off and see how it looks from there. If you pull the governor off you have to pull the intake access plate at the same time, neither one wil...

Has it got a generator or alternator on it? I have never heard of a positive ground alternator. I know Chrysler converted to negative ground when they went to 12Volts in 1956. Not sure about Ford. I just dug up a 65 Motors truck manual. It shows two generators and two alternators available in 59. Th...

Brian You are right that timing should have no effect with the secondary wire pulled out of distributor and being held near ground. For the tests we are doing you don't need to turn the starter over. There is something wrong with the voltage readings you are getting. As long as the ignition switch i...

Lavoy No problem, amybody with any ideas on how to help Brian is welcome. From my electronics background I consider the low voltage wiring the primary circuit. That is from ground to the positive term. of battery, thru battery to negative term., on thru ignition switch to coil neg. term. thru coil t...

Brian If you have 6 volts at the negative terminal of the coil, 6 volts at the positive terminal with points open, and no volts at the positive terminal with the points closed. You should be able to hold the secondary wire within 1/8" of ground and open the points and get a spark. Do you have access...

Brian The basic theory of operation is with voltage at the negative terminal, a current flows thru the coil primary and the points to ground. This current builds up an electromagnetic field within the coil. When the points open the current flow stops and the field collapses. This collapsing field in...

Brian With all the wires loose from the coil the primary winding should measure a low resistance, probably under 50 ohms, this is between the positive and negative terminals. the secondary should measure somewhat higher maybe 1K or more, this is between the center terminal and the positive terminal....

Brian your first sentence tells the tale. On a positive ground system there should be NO voltage difference between the ignition switch and the negative terminal of the coil. And with the switch off 0 ohms resistance. Ohmmeters have a low tolerance for external voltages. At best you can let the smok...
