What should I do if the engine belt is loose? Is it necessary to replace or repair it directly? How can I judge whether the engine belt is excessively elongated or damaged?
The reason is basically that the engine belt has been aging and slack for a long time. There is also the fact that the belt is normal because the screw is loose, but the belt is slack. The other is the weather. The heat and cold of the machine cause the belt to appear slack. This basically does not appear in summer. The engine belt loose can restore the belt to the proper tension by adjusting the limit screw of the tensioner (the wheel without load). If the belt is worn out due to wear and aging, it should be replaced in time.
If it is the engine crankshaft (drive wheel) belt, if it is not treated in time, it will affect the normal operation of the water pump (wheel), generator (wheel), air conditioning compressor (wheel), steering booster pump (wheel), air compressor, etc. The overall working condition of the engine can even damage the engine or cause a safety accident. If the engine belt is found to be loose, it should be disposed of in time.
The belt has been worn for too long and has aged, and that is what needs to be replaced. If the belt can still be used, it can be adjusted. On the pulley with the belt, there is an adjustable screw. After loosening the screw, press the pulley with the skid stick, and then tighten the screw, but still There is a belt that can't be too tight, and you have to have a half-centimeter swing distance.
The engine belt is an important connecting piece for connecting the auxiliary machines. The daily maintenance is not timely, or the overloading and poor driving behavior may cause the engine belt to break, which will bring you unnecessary trouble. More severely, it can cause engine damage, forcing you to overhaul the engine. Daily check the tension of the belt: press the belt in the middle of the pulley with the thumb, about 4~5kg vertical pressure, the belt pressure is between 10mm~15mm, then the belt tension is considered suitable. If it is too tight or too loose, it must be adjusted in time.
The inspection found that the belt was cracked and worn, and should be replaced immediately to avoid belt breakage. 1-2 belts should be kept in the emergency kit and should be replenished in time to cope with unexpected needs.
