The nipple connector can be unlocked by pulling the locking clip (fig. 2.352).
The hose/tube should be disconnected without any additional means.
Installation
When replacing the sealing ring, insert it into the groove of the boost air hose. Make sure that the ring is completely seated in the groove.
Lubricate the sealing lips and O-ring with oil.
Fig. 2.353. Locking and unlocking positions of the retaining bracket
Move the locking bracket to the unlock position 1 (fig. 2.353).
Press the boost air supply hose into the coupling until it stops.
Move the locking bracket to the locking position 2 and press the hose again, finally (fig. 2.353).
By pulling, check the correct fit and secure fixation of the hose in the coupling.
Hose connections with spring clamps
Fig. 2.354. Spring clamp
Note: After removing and installing the booster air tubes with spring clamps, there is a high probability of the hose "slipping off" while driving. For this reason, spring clamps are installed, which are then allowed to be opened if the corresponding booster air tube is faulty (fig. 2.354).
In case of repair, the spring clamp must be broken using a suitable tool and replaced with a new one.
