How to deal with agricultural diesel engine rod bearing knocking sound
Phenomenon: This is a short "dang, when, when" sound. The higher the speed, the louder the percussive sound, the more pronounced the sudden increase in throttle. Causes: 1. The lack of oil in the oil pan or the quality of the oil and the grades do not meet the requirements; the lubrication oil road is blocked or the engine oil is faulty. 2. The connecting rod bearing and the connecting rod bearing wear too much, and the radial clearance is too large. 3, connecting rod screws loose or broken. 4. Crankshaft centrifugal clean room is blocked. 5, crankshaft centrifugal cleaning chamber oil plug loose. Diagnosis: After this fault occurs in the diesel engine, the compression force of the cylinder is insufficient and it is difficult to start. And at the same time the knocking sounds, the oil pressure drops. If the oil indicator cover is removed, the indicator buoy can be pressed by hand (in normal times the indicator buoy cannot be pressed down).
