MAINTENANCE OF THE CRANKCASE GAS
RECIRCULATION SYSTEM
2/3
1.2. Inspecting the installation
-
Detach the hose clamps and wash any oil condensate and water out of the hose.
-
Clean the pressure control valve.
1.3. Performing the start-up procedure
-
Carry out the operations of a normal start-up (see IT-C-A-25-024e). If the red indicator is fully extended, push
it down with your finger, before starting the engine.
-
Record the crankcase pressure with the engine on load and the time (number of hours of operation) for the
next filter change. Set the control valve at an initial crankcase pressure of minus 4mbar. This valve shall not
be readjusted until the filtering cartridge is changed again; therefore, we recommend removing its operating
lever.
