In the hydraulic power steering system, the steering pump and steering gear work frequently, which will produce a large amount of metal chips and impurities, which will increase the wear of the steering system and shorten the service life of the steering pump and steering gear. Therefore, the steering oil needs to be changed regularly, and the steering oil filter should be replaced at the same time.
It is particularly important to note that the hydraulic power steering system generally adopts the method of oil return filtration, that is, the added steering oil directly enters the steering gear, and the return oil of the steering gear passes through the steering filter. Therefore, pay special attention when adding and replacing the steering oil, and do not bring dirty things in, otherwise it will directly damage the steering gear.
