The need to replace the high pressure hose can be caused by a ruptured rubber tube, corrosion of the reinforcement layer or a blockage of the passageway. Replacing the hose is reduced to dismantling it from the system connecting flanges and installing a new hose using a wrench.
The high pressure hose is designed to supply the working fluid to the power steering cylinder. Structurally, the hose consists of a rubber tube, at the ends of which there are 2 fittings. In most high-pressure hoses, the tube is reinforced to increase strength. The need to replace the hose may be dictated by its rupture, clogging or corrosion of the reinforcing layer.
The need to replace the hose
The high-pressure hose fittings are practically not subject to breakdowns, so replacing it is reduced to changing the rubber tube while maintaining the standard fittings. This method is not inferior in terms of reliability to a complete replacement of the hose and provides for significantly lower material costs. Replacement of the high pressure hose can be carried out both independently and by specialists of auto repair shops specializing in the repair of elements of hydraulic systems.
Operating procedure
Before starting work, the front of the machine must be jacked up. For convenience, it is better to set the steering wheel to the extreme left position. After that, you need to remove the working fluid from the power steering reservoir using a syringe, at the end of which a rubber tube is fitted.
Different high pressure hoses can have different connection designs. A wrench of the appropriate size is used to disconnect the nipple. The hose connection is sealed with copper gaskets, which must be replaced in case of severe wear.
After removing the hose, plug the holes to prevent hydraulic fluid from spilling onto the floor. The selection of the hose for replacement must be carried out while maintaining its diameter, since changing the size of the section can affect the performance of the hydraulic booster. In case of partial replacement of the hose, the rubber tube is dismantled, after which a new tube is pressed onto the connecting bosses of the fittings.
The new hose is mounted on standard fittings. The fasteners are tightened with a wrench. The design features of some car models require the use of cardan wrenches, since it is problematic to tighten the fastener using a conventional wrench due to the lack of free space. After installation, fluid is poured into the power steering system and its operation is tested.
