This document is valid for different design variants of turbochargers. There may be sections and descriptions of components that are not relevant for a specific turbocharger variant. Please contact an ABB Turbocharging Service Station if you have any questions regarding a design variant (see Contact information at www.abb.com/turbocharging).
Safety Introduction Turbochargers manufactured by ABB reflect the state of the art. The respective safety and health protection requirements are met. This ensures safe operation of the turbocharger. Nevertheless, there may be some residual risks during operation of and work on the tur- bocharger which: ¡...
The use of the turbocharger is limited to the specific application released at the time of de- livery. ABB accepts no liability and rejects all warranty claims for any non-intended applications. [1]Euromot = The European Association of Internal Combustion Engine Manufacturers...
If during external inspection anomalies are found or if a particularly strong deflagration event has taken place, it is also recommended to check the bearings of the turbochargers before the next start. An ABB Turbocharging Service Station should be instructed to carry out this inspection.
If warning plates are not present in the designated locations or not readable, proceed as fol- lows: Order new warning plates from ABB Turbocharging Service Stations. Remove any warning plates that have become unreadable. Clean and degrease the areas designated for the warning plates.
Locations of the rating plates The locations of the rating plates are defined in the Operation Manual. Periodic check of the pressure vessels The pressure vessels used by ABB Turbocharging, such as those for wet or dry cleaning, are so-called "simple pressure vessels". ¡...
Lubricants and pastes used during assembly can liquefy or vaporise and escape as oily fluids during the initial hours of operation. Continual escape of an oily fluid indicates an oil leak. If there is a leak, contact an ABB Turbocharging Service Station. Commissioning after taking out of operation...

6.2.3 Service work on turbocharger every 18000 hours It is recommended to have this service work and these checks carried out by an ABB Tur- bocharging Service Station. Damaged and worn out parts must be replaced with original ABB parts.

6.2.4 Service work on turbocharger every 36000 hours Service work on the rotor and bearing parts must be carried out by an ABB Turbocharging Service Station. Damaged and worn out parts must be replaced with original ABB parts. Take note of correct customer spare part set (see chapter Ordering spare parts →120).
The interval between the cleaning cycles depends greatly on the operating conditions. Cleaning should normally be carried out every 50 hours of operation. If the specified cleaning interval is incompatible with operation of the engine, contact ABB Turbocharging. Cleaning method and operating state The compressor is cleaned during operation using the wet cleaning method.
Repeating the cleaning If the cleaning is still unsuccessful after three processes, it is recommended to have the tur- bocharger checked and cleaned by an ABB Turbocharging Service Station if the engine val- ues are unsatisfactory. Volume of water per cleaning process...

Repeating the cleaning If the cleaning is still unsuccessful after three processes, it is recommended to have the tur- bocharger checked and cleaned by an ABB Turbocharging Service Station if the engine val- ues are unsatisfactory. Optimum cleaning effect It is important that the specified amount of granulate is blown in for each cleaning process in order to achieve an optimum cleaning effect.
To prevent significant loss of efficiency, specific tolerances must be fulfilled. ¡ If there is any doubt about the extent of the rubbing, contact an ABB Tur- bocharging Service Station. ¡...
The specified tightening torques of the bolted connections must be observed. Tightening torques for assembly devices Unless otherwise described, the screws and nuts of the assembly devices supplied by ABB must be tightened in such a way that they are tight-fitting.
Clearances outside the tolerance Serious damage to engines or property can be caused by clearances outside the tolerance and excessively worn parts. Have the components assessed and, if necessary, replaced by an ABB Tur- bocharging Service Station. Fig. 43: Measuring axial clearance A The axial clearance (A) of the rotor should always be measured before and after service work.
A275-L Table 32: Maximum admissible loosening torque (51087) If a threaded stud (51086) shears off when loosening, an ABB Turbocharging Service Sta- tion should be contacted. If a threaded stud (51086) works loose when removing the nut (51087), it should be refit- ted, after disassembling the gas outlet casing, up to the stop in the gas inlet casing until hand-tight.
840 Nm Table 33: Maximum admissible loosening torque (51087) If a threaded stud (51086) shears off when loosening, an ABB Turbocharging Service Sta- tion should be contacted. If a threaded stud (51086) works loose when removing the nut (51087), it should be refit- ted, after disassembling the gas outlet casing, up to the stop in the gas inlet casing until hand-tight.
Clearances outside the tolerance Serious damage to engines or property can be caused by clearances outside the tolerance and excessively worn parts. Have the components assessed and, if necessary, replaced by an ABB Tur- bocharging Service Station. Fig. 57: Measuring axial clearance A The axial clearance (A) of the rotor should always be measured before and after service work.
Impermissible vibrations and unbalance values can cause serious damage to the engine or property during operation. It is imperative that the following work is carried out after emergency operation with a locked rotor by an ABB Turbocharging Service Station: Remove rotor and check for unbalance...
If the nozzle ring is removed for emergency operation, the clamping of the cover ring (57001) to the gas outlet casing must be ensured. In this case, additional washers (01) must be provided in accordance with the following table. These washers (01) are not supplied by ABB. Fig. 67: Ensuring clamping of the cover ring...
The chapter is only applicable for engines with several turbochargers and joint air and ex- haust gas receivers. The cover plates for the compressor casing outlet, gas inlet and gas outlet are not included in the ABB scope of delivery. The following figure shows the positions where to fit the cover plates.
If the acid number (TAN) is greater than 2 mg KOH/g, the following mothballing measures are necessary after taking the engine out of operation: Dismantle the turbocharger. The rotor and bearing parts must be dismantled and subsequently refitted by an ABB Tur- bocharging Service Station. Clean all parts.
¡ The casings of the turbocharger remain attached to the engine, the rotor and bearing parts are dismantled by an ABB Turbocharging Service Station and stored separately ¡ The turbocharger is completely removed, either as a whole unit or in individual parts For the measures always necessary for preparing the turbocharger parts for mothballing, see section Taking the engine out of operation for up to 12 months, subsection Preparations...
