Taking a turbocharger out of operation

9.2

Locking the rotor

9.2.1

Introduction

CAUTION

Cooling of a locked rotor
Serious damage to engine or property can be caused by the overheating of

intact turbocharger components.

If the gas inlet is not blanked off, the lubricating oil supply remains switched

on (see section Further information for operation of 4-stroke engines with

locked rotor).



If there is a lubricating oil leak on the turbocharger, stop the oil supply.

A locked rotor must be removed after emergency operation and checked for unbalance (see

chapter

Removing the cartridge group [➙

67]).

The unbalance check must be carried out by an ABB Turbocharging Service Station.

Exception

The exception concerns customer requirements for test bed runs of new engines at a maxi-

mum engine load of up to 25 %.

In these cases, subsequent removal of the rotor is not required as the engine is only operated

briefly with a locked rotor.

In these test bed runs, it is not allowed to remove any set screws from the compressor wheel

when fitting the locking device (see section Fit

ting the locking device [➙

95]).
