Otherwise, the plastic thread will be damaged thereby destroying the air spring (41). When replacing the air spring (41): ↓ Break open the clamping ring, detach pressure line connection and insert the pressure line (41a) up to the marking in the new pressure line connection. Pull back pressure line (41a) a short distance so that the peripheral retaining edges in the inside of the clamping ring engage in the line outer surface. If pressure line (41a) is damaged or leaky or if pressure line connection is damaged: ↓ |
