⇒ Close all openings which form when certain parts are removed e.g. pipes, oil
holes etc. to prevent dirt from entering the engine. (This includes also the
pipes which are removed).
⇒ Check all repaired, overhauled or replaced parts for perfect functioning before
starting the engine.
⇒ Check all pipes which have been removed, for tightness after they are refitted.
⇒ Clearances of moving parts must be checked periodically. Should the maxi-
mum permissible values (see Clearance Table 0330−1) have been reached or
even exceeded, these parts must be replaced.
⇒ Arrange to replace all parts taken from spares stock. When ordering new
parts refer to the Code Book, mention code numbers and description.
D When tightening studs, nuts or screws, take the utmost care not to damage
their thread. They must be screwed in by hand until metal to metal contact is
achieved. Always use the specified lubricants on the threads.
D Adhere to tightening values wherever they are indicated. Use the specified
lubricant on the threads (see 0352−1 and 0352−2).
D Locking devices of bolts, nuts, etc. must be fitted correctly and secured prop-
erly. Use locking plates and locking wires only once.
D For threads of screws and studs which are getting very hot, (i.e. exhaust pipe
or turbocharger fastenings) apply a high temperature resistant lubricant be-
fore assembly, to prevent a heat seizure.
D Used rubber rings must always be replaced by new ones when an overhaul of
any engine component takes place; they must conform in dimension and qu-
ality to the Wärtsilä specifications.
The fitting of piston seal rings and rod seal rings requires the greatest of care
to prevent damage, over expansion or deformation. Before fitting the rings
heat them first in boiling water.
