    D722 Electrical Oil/Temp/Fuel Solenoid

    I hear ya about being paranoid. It is easy to create trouble where there is none. Too many systems to track other systems will get complicated. We know if it is made by man, it will eventually fail. I suppose we should replace parts (belt [done] and hoses) that are known to fail in the long term...

    D722 Electrical Oil/Temp/Fuel Solenoid

    I have ordered a 160*F KLIXON. We will see where that leads. I think the hottest portion of the exterior head will be 20*F cooler than the coolant. I am not positive, but it is a starting point. I feel better we are moving ahead with securing the engine to be able to be left unattended for...

    D722 Electrical Oil/Temp/Fuel Solenoid

    I just contacted Thermo King and the parts guy said there is no thermal switch on the engine, only a temperature sensor. The on/off cycles are controlled by the ECU. Maybe he is too young to remember non-ECU units? I will try a local truck repair shop who has seen a lot of older equipment.

    D722 Electrical Oil/Temp/Fuel Solenoid

    Again...a potential solution . I have to wonder, though, is the external surface of the head the same temperature of the coolant? What is the difference? I can take my digital thermal gun to read the temperature to read the maximum normal temperature where it is at its highest and purchase a...

    D722 Electrical Oil/Temp/Fuel Solenoid

    My friend is Amish and certainly not up on ECU control. I could design and assemble an electronic monitoring system, but he would not prefer that since it is beyond his understanding. In fact, keeping the engines operating with minimal control oversight is preferred. Engine protection from...

    D722 Electrical Oil/Temp/Fuel Solenoid

    We have a D722 driving a lineshaft. Currently it has been configured with the fuel solenoid grounded to the block. The solenoid gets power once the oil pressure comes up to "minimum" for the current oil switch. The temperature sensor/switch was replaced at some point with a non-oem switch and...
