description

The function of the tension wheel is to adjust the tightness of the timing belt. It is generally replaced with the timing belt to avoid worries. Other parts need not be replaced. The timing tensioner is mainly composed of a fixed shell, a tension arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve, etc. It can automatically adjust the tension force according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.
The tensioner is a vulnerable part of automobile and other spare parts. The belt is easily stretched after a long time. Some tensioners can automatically adjust the tension of the belt. In addition, with the tensioner, the belt runs more smoothly and has less noise, and can prevent slipping.
what is the abnormal noise of the tensioner
The abnormal noise of the tensioner is the continuous squeaking noise near the engine belt, and the tone becomes sharper as the engine speed increases. The tensioner pulley is a belt tensioning device used in the automobile transmission system. Its function is to adjust the tightness of the timing belt and automatically adjust the tension force to make the transmission system stable, safe and reliable.
The tensioner is mainly composed of a fixed shell, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve.
First of all, you must determine the location of the sound, open the hood, and roughly determine whether the sound is from the top, middle, or lower part of the engine, or front, middle, or rear.
The abnormal noise of the timing belt tensioner bearing is basically the same as the abnormal noise of the power steering hydraulic pump bearing, generator bearing, etc. It is a continuous rustling sound, and the tone becomes sharper as the engine speed increases.
The timing belt tensioner bearing is located in the timing belt cover of the engine, so the location of the abnormal noise cannot be determined by external inspection. If the engine has abnormal noise similar to the bearing, but there is no abnormal noise in the external accessories such as the water pump, generator, power steering hydraulic pump and so on with a long-handled screwdriver or stethoscope, it can be preliminarily determined as the timing belt tensioner bearing Abnormal sound. At this time, disassemble the timing belt cover, take out the timing belt and all timing belt tensioner bearings, turn the bearings by hand, and carefully check the bearings for abnormal noise and jams.
The bearing of the timing belt tensioner has to withstand greater lateral pressure, so when you turn the bearing by hand, as long as you can feel a slight abnormal noise or jamming of the bearing, it means that the bearing has been damaged and it will be generated during use. Abnormal noise should be replaced immediately. Listen to the sound in the crankcase as soon as you open the oil filling port cover, listen carefully from the oil filling port, and repeatedly change the engine speed test.
