Notes on repairing air-spring struts
Note:
As of a mileage of 200,000 Km it is recommended that the air springs be replaced per axle if there is damage to one air spring.
If the shock absorbers leak, the complete air spring strut is to be replaced. The oil of the shock absorber can damage the roller.
When depressurized, the air spring must not be twisted. There is the danger that the roller in the inside of the air spring will be damaged
by bending or folding and thus significantly reduce the running time.
Air-spring strut
1. Before loosening the air lines in the installed state, check if the rolling boot is still filled with the residual pressure of approximately 3 bar. To do
this, press on the rolling boot of the air spring with your thumb. The rolling boot must give perceptible resistance. If no significant resistance can
be felt, the air spring is depressurized and must be replaced along with the residual pressure retaining valve.
The greatest possible care and cleanliness, as well as perfect tools are important requirements for carrying out perfect repairs on air-spring struts.
The general and basic rules of safety apply. These are specifically listed here again for repairing air-spring struts.
-
Thoroughly clean the connection points and their surroundings before loosening them.
-
Do not use fiber-shedding cloths.
-
Do not take spare parts out of the packaging until right before installation.
-
Only use lubricants that have part numbers.
