Impact of oil leakage from automotive tensioner
Oil leakage from car tensioners can affect vehicles in many ways :
aging and corrosion of oil seal : One of the main reasons for the oil leakage of the tensioner is aging and corrosion of the oil seal, which will lead to the deterioration of the sealing performance, resulting in oil leakage. If left untreated, the spill could worsen and could even cause serious mechanical failure.
The impact of sealing material : rubber seals exposed to the alternating cold and warm environment for a long time will lose plasticizer, resulting in shrinkage and hardening of seals, weakening elasticity, resulting in oil leakage.
vehicle performance degradation : Oil leakage of the tensioner will cause the timing chain of the vehicle to lose tension, which will interfere with the normal operation of the engine and affect the overall performance of the vehicle.
hidden danger : Ignoring the oil leakage of the tensioner may lead to sudden failure during driving and endanger driving safety.
Prevention and response measures
In order to prevent and respond to the problem of oil leakage from the tensioner, the following measures can be taken:
timely replacement of invalid oil seal : If leakage is found, the oil seal should be updated in time to avoid oil leakage due to the aging of the oil seal and the loss of elasticity.
Attach importance to the role of gasket : the gasket between the parts of the car's resting part plays a leak-proof sealing role to ensure that the material, production quality and installation meet the technical specifications.
regular inspection and maintenance : regular inspection of vehicles, timely find and solve the problem of oil leakage, to avoid oil leakage caused by problems such as ventilation plug and check valve blockage.
Proper installation and fastening : Ensure that all kinds of fastening nuts are tightened according to the specified torque to avoid oil leakage caused by improper installation.
Why does the tensioner break
Timing belt failure
The main cause of tensioner damage is usually caused by timing belt failure. Failure of the timing belt will cause the tensioner to not work properly, which will lead to damage to the tensioner. This damage is irreversible, so it can only be fixed by replacing a brand new tensioner and cannot be repaired.
Specifically, the tensioner plays a guiding and tensioning role in the operation of the engine, ensuring that the timing belt or chain is always in the best tensioning state, preventing the belt from slipping, skipping teeth or loosening off, thereby reducing the wear of the sprocket and chain. If there is an abnormal noise in the bearing inside the tensioner, it may mean that the bearing has been damaged, which may lead to the timing of the engine, ignition and valve timing disorders, which will affect the normal use of the car. If it is not replaced in time, it may cause engine jitter, ignition difficulties, or even failure to start in serious cases, may also lead to valve deformation, damage to engine parts, and even lock phenomenon, so that the belt can not drive normally, resulting in car breakdown.
In addition, improper operation during assembly can also cause damage to the tensioner. For example, if the position of the timing belt is not properly adjusted during assembly, eccentricity may occur, resulting in accelerated wear of the tensioner.
To sum up, the main reason for the tensioner damage is the wear and stress problems caused by the failure of the timing belt or improper assembly
