Troubleshooting 1965 Hough with Cummins Engine Shutting Down After Four Minutes

Question:

Hello, I own a 1965 Hough equipped with a Cummins engine that has been running smoothly since I acquired it in 2002. However, recently I've been encountering an issue where the engine runs for about four minutes and then suddenly shuts down without any sputtering or coughing. I've already drained the fuel tank, inspected it, and replaced two filters - a PF-132 and a 3107. I suspect that the 3107 filter is an additional one. I also checked and cleaned the small metal filter in the component that the throttle pedal connects to, although it was not very dirty. Despite using new fuel, batteries, and filters, the problem persists. I usually start the engine with diesel ether, as advised by the previous owner, although I am aware that this may not be the best method. The cold start panel is not functioning, but I plan to address that in the future. I primarily use this machine for snow removal on weekends, as I have a long driveway. I welcome any thoughts or suggestions regarding this issue. I am considering if the problem could be heat-related, particularly with the water pump causing issues after the engine runs for a few minutes. While I am not very technically savvy, I am struggling to find a solution. Any assistance is greatly appreciated. Thank you.

It has been quite some time since I last came across a Cummins J series engine. I have only had the opportunity to work on one in the past. If you are facing issues with the fuel solenoid, look for a small Knurled knob near the metal filter screen on the front. By turning this knob, you can manually open the fuel solenoid and rule out any electrical issues or internal breakdown of the solenoid coil. Providing pictures would greatly assist in troubleshooting.

Mechanic mentioned that it has been a long time since they last saw a Cummins J series engine. They only had the opportunity to work on one in the past. If you are facing issues with the fuel solenoid, there should be a small knurled knob located near the metal filter screen that can be manually adjusted. This can help rule out any electrical issues or internal breakdown of the solenoid coil. It may be helpful to share pictures for further assistance. Coincidentally, I have an old 1958 J series operation and maintenance manual. As I reviewed the section on the fuel pump, it appears that earlier versions may have had a slotted headed screw instead of a knurled knob. Nonetheless, the knob or screw should be located close to the small solenoid and filter screen cap. I have attached a drawing with a red arrow pointing to the screw for you to try turning. Keep in mind that if this keeps the engine running, you will need to back it out to shut it off as it overrides the solenoid. Apologies for the misspelling of "solenoid."

mekanik mentioned that they haven't encountered a Cummins J series in many years, having only worked on one previously. If you're facing issues with the fuel solenoid, try looking for a small knurled knob near the metal filter screen that allows you to manually open the solenoid. This can help rule out electrical problems or internal issues with the solenoid coil. Providing pictures for better assistance would be beneficial. I appreciate the advice and will give it a shot.

kshansen mentioned that in an old 1958 J series operation and maintenance manual, it was noted that earlier versions may have had a slotted screw instead of a knurled knob near the small solenoid and filter screen. Referencing a drawing with a red arrow pointing to the screw to try turning, it was advised to back it out to shut off the motor if it keeps running, as it overrides the solenoid. It was discussed that the shutdown valve may need rebuilding or replacement if this method proves effective. Apologies for any misspellings in the original post.

If you're experiencing issues with your system shutting down, it could be due to wiring problems or a failing shutdown valve solenoid.
