Power Steering Line/Hose: Service and Repair

Notes on Hydraulic Line With Quick-Release Coupling





1) Quick-release coupling with ID marking

Removing:
Push quick-release coupling (1) against pipe (4) (thereby relieving strain on spring (2)).
Press plastic ring (3) into quick-release coupling (1) and remove coupling (1).

Assembly:
Markings (K) on coupling (1) and pipe (4) must be flush.
Push quick-release coupling (1) onto pipe (4) until a "click" can clearly be heard.
To check that quick-release coupling (1) has been installed correctly, pull it back forcefully.





2) Quick-release coupling with indication pins

Removing:
Press plastic ring (2) into quick-release coupling (1) and remove coupling (1).

Assembly:
Push quick-release coupling (1) onto connector (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing.
To check that quick-release coupling (1) has been correctly fitted, feel indication pins (4) at outside diameter of housing. When correctly seated, indication pins (4) cannot be pressed into housing.

Caution!
Coupling is not correctly engaged if both indication pins (4) fail to protrude from housing. Leakage is thus unavoidable.
