AIR SPRING MAINTENANCE AND INSTALLATION GUIDE
• Control the air entrance and other connections against leaking.
• Control surrounding for enough space while inflation. Usually min. 36 mm space is required for diameter
increasement under high pressure.
• Control periodically the suspension’s required rice height at suitable position. The measurement must
be +/- 7 mm in order to avoid bottoming out or avoid occuring shocks cause by extreme expandings.
• Place the air spring at high position and if necessary clean the air spring free from unknown materials
with cleaning solution which should not be petrol derivatives.
• Control the air spirng piston surface free from unknown material on it. Corrodes on the piston may
decrease the life of the air spring. Cleaning of them is your requirement in the regular controls.
• Control the shock absorbers against leaking, cracked connections, eroded bushes and extreme expandings.
• Control the bolts and nuts torque applied at suitable level. Please refer to manufacturer’s manual for more
specific information.
• Control the weight control ventile working properly. If necessary clean or replace it with a new one.
Regular maintenance of valves will save you from hundreds of Euros.
• Your vehicle’s life increases and reduce your overall maintenance expense with regular controls as above
mentioned.
CAUTION
• Please do not inflate the air spring without fixing the vehicle suspension system or any suitable structure.
• The pressure should not exceed 100 psi/bar, Otherwise damages may be occured.
• Working temperature is between -40’C and +70’C
AIR SPRING INSTALLATION GUIDE
Prior to install suspension air spring, please make sure all the necessary equipments are ready to use.
Please look over to the service manual of the manufacturer in order to gain proficieny to the suspension system.
If you have any doubts please contact with a specialist or suspension manufacturer or air spring
manufacturer’s asistance.This prevents you losing time and protect for further damages.
• While disconnecting loading adjustment ventile,control the twisted or broken connection.Replace if
necessary.
• Control the shock absorbers for possible replacement.There are 2 warning sign for worn shock absorber.
If the shock absorber can be eassily compressed or extended then they are needed to be renewed.The shock
absorbers must be hot to the touch while the vehicle is on the service if not, then they are needed to be
renewed. Please do not forget regular shock absorber maintenence is the key for increasing the life of air spring.
• When the air inlets are removed, it is necessary to control against cracks and other damages. Besides
control the connection for loose and replace if necessary.
• Sometimes failures of the air spring are clear or easily realized,sometimes failures are not realized. In
case of unrealized stuation remove the air spring and correct the main problem.
• When the suspension air spring is removed other suspension parts can be reached easily, therefore
control the damages and worns on chasis connections,bushes and torque rods. Replace these parts if
necessary.
• Furthermore control the installation groove for the air spring. Remove and make sure for the any obstacles
and sharp edges which will damage the new air spring.
• Prior to install the new air spring clean the bead plate surface for installing.
Always use new nuts for installing. Old ones may occur failures.
• Control the adjustment rod working properly. Normally adjustment rod moves through intake position under
load.Returning of this rod’s starting point will let the air inside the air spring. When unloading the vehicle
adjustment rod will move to exhaust position. This opens the exhaust valve and let the air outside untill the
rod returns starting point.
