If there is oil loss, plug the turbochargers
8
Switch on the manual mode of the auxiliary blower
9
Make sure you are within the load restriction
10
Verify the maximum firing pressure
NOTE:
The load restriction for 1 out of 2 turbochargers is 40%. The load restriction for 1 out of
3 turbochargers is 55%. The load restriction can be increased considerably, if an orifice
plate is also inserted in the turbine inlet.
NOTE:
If reducing the load doesn’t help and the turbocharger has problems running even at
reduced load, then consult the turbocharger manual for further advice.
The turbocharger has been cut out successfully. The engine is now running under a special running
condition.
If it is possible to run for an extended period of time with a turbocharger out of operation, then
proceed like this:
C.) For engines with one turbocharger and the exhaust bypass option:
1
Stop the engine
2
Open the cover (E)
3
Lock the rotor of the faulty turbocharger (check your turbocharger manual for details)
4
Remove the blanking plate (T1, T2, T3, T4) from the exhaust bypass pipe
5
Remove the compensator (1) between the compressor outlet and the scavenge air duct.
6
Remove the expansion piece (2) for the air outlet of the turbocharger (F)
7
Insert an orifice plate (3, 4) in the compressor outlet
