If the truck engine is accompanied by abnormal noise during operation, and the oil pressure is low and the alarm is often on. Some people may simply think that these problems will occur because the oil is not added enough, but after adding oil several times, it is found that the root cause of the problem has not been solved. This kind of fault problem is mainly caused by abnormal wear of the engine crankshaft bearing, which causes abnormal engine noise and low oil pressure. So how can we try to avoid these situations?
First of all, in terms of lubrication, add enough oil that meets the requirements, clean the oil filter regularly, replace the filter element, and eliminate the hidden dangers of diesel engine oil leakage. Further ensure the smooth flow of the diesel engine main oil channel, crankshaft oil channel and each lubricating oil channel, ensure the cleanliness of the lubricating oil and replace it regularly.
At the operating level, when the oil temperature and water temperature of the diesel engine are low, do not suddenly increase the throttle, increase the speed and load. When the oil temperature is too high, do not stop immediately (usually the oil temperature needs to be lower than 60 degrees). In addition, reduce long-term overload working conditions and try to control the oil temperature within the specified temperature. Excessive oil temperature will reduce the oil viscosity.
In terms of maintenance, keep the engine parts clean and prevent carbon deposits, fuel and cooling water from entering the lubrication system. At the same time, use qualified shafts and bearings, and regularly inspect and maintain them, and replace bearings with abnormal wear. In addition, ensure that the clearance between the journal and the bearing meets the requirements and the oil supply is sufficient.
Many truck drivers often use cheap and unqualified oil from roadside stalls, and they are mostly responsible for heavy-load transportation, with many slopes and heavy engine loads. Under the action of inferior oil, abnormal wear of the bearings is gradually formed.
Summary
As one of the important parts inside the engine, the bearing will frequently withstand various forces such as pressure, friction, and bending stress during operation, and the working conditions can be said to be very harsh. For most truck drivers, avoiding overloading and overweight, and avoiding keeping the engine under high load for a long time can further extend the service life of the engine. At the same time, don’t be greedy for small bargains and use inferior oils. Regular maintenance and repairs are basically enough.
