How long is the power steering fluid replacement? How to maintain car hydraulic power steering system
Power steering is a car on a new technology of increasing the comfort, can automatically provide the driver for steering force, so as to reduce labor intensity of the driver's steering, power steering oil is filling in power steering system of a medium oil, have the effect of the steering force and buffer. Many car owners to ignore the importance of assistant steering fluid, such as out of the question to check to replace the power steering fluid, it is wrong, the general power steering fluid needs to be changed every 30000 kilometers.
To run partial phenomenon is due to failure of maintenance when the redirector assembly or adjust, especially the steering worm gear and worm and hydraulic oil distribution valve assembly and adjustment improper, can cause to wandering, sometimes, two front wheel brake adjust uneven can also cause new wandering.
Steering heavy is caused by the steering hydraulic booster system doesn't work, it has nothing to do with to mechanical parts. Cause to heavy concrete are: hydraulic oil; System sealing performance is poor, there are internal air into the hydraulic system; Hydraulic gear pump cavity badly worn or drive hydraulic pump belt gear damage, all of these can lead to hydraulic booster system doesn't work.
To send the pendulum phenomenon is due to more connecting mechanism pine kuang, wheel alignment, the differences between the two front wheel tire caused by improper. To have a louder noise is due to the drive pulley more loose kuang, steering pump fixed bolt looseness or fuel reservoir fluid level is too low.
Combining with the above several kinds of circumstances, we should correctly in practical work to use and maintenance of the hydraulic steering mechanism. Specific should do the following:
1. During maintenance, shall check the firmness of steering pump belt, look to whether have fracture, if any should be replaced in a timely manner, looseness should press with finger it is advisable to 1 cm;
2. Check the pipe joint of the hydraulic system for oil leakage, hydraulic tubing should try to avoid friction with other parts, to prevent breakage intake, at the same time, the hydraulic hose should be replaced periodically, prevent peeling from the hose pipeline;
3. Regularly check whether the steering hydraulic oil is lack, such as lack of should be added, at the same time, regular cleaning of the hydraulic oil cup and filter, to prevent the hydraulic oil dirty or bad, suggest every travel 30000 km to replace hydraulic oil;
4. Turn, the direction may not be "killed", especially in the spin, should have a certain margin, guarantee the normal work of the hydraulic steering system;
5. The maintenance steering, should install properly, especially between worm wheel and worm assembly, steel ball must then vow, slippery course no deformation of the steel at the same time, the hydraulic oil distribution valve and piston chamber wall to clean, choose high quality, model matching oil seal to prevent leakage of hydraulic oil.
