  Check whether the compressor wheel cooling is fitted on the bearing casing. 
Version with water-cooled bearing casing 
 
 
Failure of bearing casing cooling 
Any prolonged failure of the water cooling will shorten the lifetime of the 
turbocharger. 
 Make sure that an uninterrupted supply of cooling water is provided during 
operation. 
  Check whether the water pipes are fitted on the bearing casing. 
3.2.3  Checks after commissioning (engine in idle mode) 
Lubricating system 
  Keep to the lubricating oil pressure at the inlet. 
  Keep to the lubricating oil temperature at the inlet. 
  Refer to chapter Monitoring operation [➙ 29] for admissible values. 
  Check all the pipes for tightness.  
3.2.4  Checks when starting up the engine 
  Measure speed, oil pressure and charging pressure at various engine performances. 
  Measure the exhaust gas temperature before and after the turbine. 
  Measure the air temperature before and after the compressor.  
  Compare the measured values with the values of the acceptance certificate. Different 
operating conditions indicate a malfunction (see chapter Eliminating malfunctions [➙ 65]). 
 
 
Lubricants and pastes used during assembly can liquefy or vaporise and 
escape as oily fluids during the initial hours of operation. Continuous escape 
of an oily fluid indicates an oil leak. 
If there is a leak, contact an ABB Turbocharging Service Station.
