This loader cat 938 G has lost torque and power, and it has thick smoke, as if it were from the Stone Age, walking on coal. I am a heavy equipment mechanic. After I diagnosed the malfunction of this loader, I found several reasons causing the loss of torque and heavy smoke, including a blockage in the carburant fuel hoses or filters, and the second reason is as In this video, I explained a blockage or obstruction in the air paths, so that a sufficient amount of oxygen does not reach the internal combustion chambers, which causes an imbalance in the fuel mixture with oxygen, and thus combustion does not occur continuously, which results in weakness in the engine, irregular cycles, and the release of thick smoke. All of these factors produce weakness. Determination
So, watch the video until the end and learn about one of the causes of loss of torque and power in heavy equipment machines. Share your opinion with us about the video content, as well as the method of diagnosing and repairing faults with simple capabilities.
