Locking the rotor
9.2
CAUTION
A locked rotor must be removed and checked for unbalance after the
turbocharger repair.
NOTICE
An exception is a test rig run up to a maximum of 25% of the engine
load in the case of new engines with one or several turbochargers. This
is sometimes requested by customers. As operation with a locked rotor
is only brief and the loads are low in these cases, subsequent removal
of the rotor is not necessary.
CAUTION
During operation of the engine with a blocked turbocharger, the lubricat-
ing oil system must remain connected to this turbocharger also and be
turned on if the gas inlet cannot be blocked. (See section Further
measures and information for operation with a blocked rotor for 4-stroke
engines.) Otherwise components that are still intact can be damaged
through overheating.
Shut off the oil supply in the event of lubricating oil leaking from the tur-
bocharger.
