Required special tools, instrumentation and fixtures: Sealing agent "AMV18820003".
Primary regulation (leading) shaft is not required. After repair, however, it is necessary to remount the provided shim, which was made at the factory. It is also possible that no shim was installed. In this case, carry out the assembly without the adjusting washer. When replacing a bearing or clutch housing or gearbox housing, the use of a washer is no longer necessary.
