Repair instructions
Turbocharger, changing
Always troubleshoot and repair any cause of damage
to the turbo before installing a new unit.
The engine’s lubrication system and intake system
must be maintained properly for the turbo to work well;
the oil and the oil filter must be changed at the specified intervals, the correct type of oil must be used and
the air filter must be maintained correctly. The first
step in installing a new turbo should therefore be be to
check the engine oil and change the filter if necessary, then run the engine for a few minutes before installing a new turbo.
Reinstall the air filter and air hose.
When changing the turbo, blow out any flakes of rust
or soot from the exhaust manifold as these flakes can
damage the turbine on the new unit.

Check the oil level and if necessary add engine oil according to specifications. See “Technical data
TAD1240GE, TAD1241GE/VE, TAD1242GE/VE,
TWD1240VE”

Start the engine and perform a functional test and leak
check.
It is also important to clean out the intake duct from
the air filter. Fragments from a damaged compressor
wheel, for example, can remain and cause immediate
damage to the new turbo.
