Service Information: Operations In Area Of Clean Air Line - Si09.00-D-0005DJ

Engine 642 in model 907 

If, as part of maintenance and repair work, work is done in the area around the clean air line or if the clean air line is removed, ensure that the seals and boots of the clean air line have not been damaged or mounted incorrectly.

This could lead to the following fault profiles: 

• Engine diagnosis warning lamp lights up
• Engine has low output, switches to limp-home, emits blue smoke
• Damage to turbocharger
• Engine damage

The clean air line seal to the turbocharger must be replaced each time the connection is loosened. Deformed or damaged boots must also be replaced.

Incorrect mounting will result in complaints about engine running characteristics.

Under certain circumstances, damaged or deformed seals on the clean air line cause damage to the engine through the ingress of dirt or foreign bodies.

The specified torque of 3 Nm for mounting the clean air line to the compressor end of the exhaust gas turbocharger absolutely must be complied with.

In the event of a complaint, the seals and boots for the clean air line are to be checked for correct seating and signs of damage. Picture documentation is recommended here.

Warranty and goodwill claims for engine damage, that has been caused by incorrect mounting of the clean air line, will be rejected by the inspection station.
