4 Disassembly and assembly
4.1 Introduction
This Operation Manual may be used to carry out only those operations that
are described in it. If the cartridge group is disassembled or assembled
incorrectly, this can lead to serious engine damage.
ABB Turbo Systems recommends having further operations carried out
only by trained staff or an ABB Turbocharging Service Station.
Marking casing position for assembly
ABB Turbo Systems recommends marking the casing positions prior to
disassembly.
Identification of the assembly devices
Not all assembly devices are marked with a part number. Identification is guaranteed by the
tool list. This list is enclosed in the toolbox.
Servicing the assembly devices
Assembly devices must be checked for damage before and after use.
Visually inspect for corrosion, cracks, deformation and wear.
Damaged assembly devices must no longer be used and must be
replaced.
Before starting operations, make sure the required customer spare part sets are available.
See chapter Spare parts [➙ 43].
Tightening torques for components
The specified tightening torques of the screw fittings must be observed (see Table 17).
