Notes on fitting hydraulic lines and hoses - AH32.50-P-0001-02A

Due to the extremely high pressures in the ABC system, proceed with great care when assembling hydraulic lines and hoses. Otherwise leaks can occur which can lead to accidents, damage to the vehicle as well as environmental pollution.

• Check sealing surfaces and any union nuts of the hydraulic lines and hoses as well as sealing surfaces and connections of ABC system components for damage before assembly and replace defective components if necessary.
• Before assembly clean sealing surfaces, connections and any union nuts thoroughly. Do not use anything other than compressed air and lint-free cloths for this operation.
• Replace sealing rings and O-rings.
• In the case of sealing rings with support ring the sealing ring should only be replaced in the event of damage. If the support ring is damaged the complete hydraulic line should be replaced.
• Align hydraulic lines and hoses with their connections free from tension.
• As far as possible tighten any union nuts by hand.
• Pay attention to tightening torques.
