Installing Rolling Lobe Air Spring with Top Plate

Air Spring Systems for Commercial Vehicles

WARNING:

  • Do not inflate unless properly secured in the suspension system of the vehicle or in some other appropriate structure.
  • Pressure may not exceed 100 psi / 7 bar. Otherwise there is a danger of injury!
  • Working temperature: -40°C to 70°C / -40°F to 158°F.

Removing the Old Air Spring:

  • Jack up the vehicle securely as high as possible. Make sure it cannot fall off its support.
  • Let the air out of the air spring system.
  • Remove the old air spring.
  • Please note that for conical rolling lobe air springs, the narrow end must be placed on the piston.

Installing Crimped bellows

  • When complete ContiTech air springs are supplied they are usually provided with bolts and/or threads to match the hole pattern of the vehicle. If the piston is to be used again, the piston and the bottom clamping plate (except for vulcanized-in clamping plates) have to be cleaned.

Installing Crimped bellows

  • Fit the air spring by the top crimping plate onto the chassis. Press bottom bead to an oval and push through the bottom clamping plate.

Installing Crimped bellows

  • Position both bottom clamping plate and piston to be in line with the hole patterns on the axles and push the clamping plate into the holes of the piston.

Installing Crimped bellows

  • Screw piston tightly to the clamping plate (if necessary, secure the air spring with the help of a second person to prevent twisting, or tighten it prior to installation).

Installing Crimped bellows

  • Fit piston on the vehicle axle. Pressurize the air spring system and lower the vehicle. The rolling lobe air spring is now fitted and will automatically roll onto the piston.
