32 41 ... Notes On Hydraulic Line With Quick-Connect Coupling

1) Quick-connect coupling with ID marking_







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

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


2. Quick-connect coupling with indication pins







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

Assembly:
When replacing hydraulic line: remove transportation lock (T).
Push quick-connect coupling (1) onto pipe (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing.
To check that quick-connect 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.

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