BMW steering oil pipe 17227583187 Industry Knowledge Introduction
It is divided into two categories: high pressure hose 17227584007 and low pressure hose. The high-pressure hose withstands 100 - 150 bar high pressure and is responsible for transferring the pressurized power-assisted oil; the low-pressure hose withstands only 1 - 5 bar pressure and is used for the return of oil. The material adopts a multi-layer composite structure, with the inner layer of oil-resistant synthetic rubber preventing leakage, the middle steel wire braid layer enhancing pressure resistance and fatigue resistance, the outer layer of wear-resistant and weather-resistant material adapting to complex environments, and cushioning or heat-insulating structures in some high-end models.
The specifications of the fuel line 17227584008 vary significantly from one BMW model to another, with the inner diameter of the high-pressure fuel line of the 3 Series being 8-10 mm and the outer diameter 12-14 mm, and the inner diameter of large SUVs such as the X5 being 10-12 mm and the outer diameter 14-16 mm, so replacement must be strictly matched to the model and the frame number.
The choice of oil is very important. Use CHF-11S special booster oil, which has excellent viscosity and temperature characteristics, anti-oxidation and anti-wear, and good compatibility. It is strictly prohibited to mix other oils, otherwise it will lead to deterioration of the fluid and damage to the system. It is recommended to change the power steering fluid every 2 years or 30,000 kilometers and to clean the fuel line.
During maintenance, if there is heavy steering, oil leakage and other phenomena, you need to check in time. Replacement is required to release the system pressure, ensure that the joints are firmly sealed, comprehensively test the power-assisting effect and sealing after maintenance, prioritize the use of original or high-quality parts, and strictly follow the maintenance specifications to ensure the reliable operation of the steering system.
