3.22 INSPECTING THE COMPRESSOR LINE
Remain at a safe distance from
rotating and/or moving components.
Note:
If excessive values are measured, the inside of
the air-dryer housing and the silencer on the vent
should first be cleaned. Then repeat the
inspection.
1. Bring the engine up to operating
temperature.
2. Bleed the system to a pressure below the
cut-in pressure of the pressure regulator.
3. Remove compressor control line (1) which is
hooked up to connection point 23 of the air
dryer. Then seal the opening at connection
point 23.
4. Build up pressure in the brake system
(pressure regulator must cut out).
5. When the engine is not running, remove the
safety valve from the compressor line and
replace it with a test nipple.
6. Connect a pressure gauge (measuring
range 0-16 bar) to the test nipple.
7. Start the engine and run it at maximum
speed.
