Air Springs “Problem – Cause – Solution”
Problem and Cause
Solution
Deformed Air Springs · improper storage · improper transport · improper handling |
|
|
· storage according to ISO 5285 no daylight, dry, at normal room temperature · avoid improper transport · avoid improper handling |
Damage of the conical beads and cuts · improperly mounted bead plate · pinching of the bellows with metal parts |
|
|
· keep conical beads clean and corrosion free · avoid driving without pressure in the air suspension |
Bellows rubs off at shoulder · bead plate diameter incorrect · bellows too long for application |
|
|
· make sure to use original parts · avoid wrong cross references |
Broken off thread bolts · excessive torque · use of oils or lubricants |
|
|
· don’t exceed recommended torque according to your maintenance manual · avoid usage of oils or lubricants |
Overextension · spring travel not restricted · incorrectly adjusted level control · air spring not suitable for application |
|
|
· check the shock absorbers · check and adjust level control valve · double check if the air spring fits the OE part number |
Abrasion · Bellows contact with chassis parts · Bellows contact with foreign bodies |
|
|
· double check if the air spring fits the OE part number · check regularly and remove foreign objects stuck between bellows and piston |
Chemical contamination · usage of oils or lubricants |
|
|
· avoid usage of lubricants or cleaners which contain mineral oils · check air springs on a regular basis |
Air Spring bursting, broken piston · overload · exceeding the maximum allowable pressure |
|
|
· never exceed the maximal allowed weight of the vehicle |
