7.7 Notes on assembly
All the details in Section 7.5 are to be observed, in
particular the notes on safety.
Good mechanical engineering practice is to be ob-
served for assembly work.
Use original spare parts. See also Section 2.3 . Do not
use defective parts.
Treat close-tolerance areas (not on stainless steel
parts) with a corrosion inhibitor. Greas screw threads
prior to assembly.
Check whether all parts fit and only then perform as-
sembly.
Important dimensions are to be checked before as-
sembly, e.g. by fitting parts together as a test.
These important dimensions are centerings, bearing
seats or bearing clearances.
During assembly, gaskets 400 , 401 and 406 are to be
replaced, intermediate rings 509 must be replaced.
Prior to assembly, remove any metallic particles ad-
hering to parts fitted with magnets.
