5. Recommendations
1) Read the data in 3301 − 1 Work Platform.
2) Do the work carefully. Make sure that all parts and equipment are clean. Use only
the applicable tools and equipment for the maintenance tasks. For data about the
tools and equipment, refer to 9403 − 5 Tool List.
3) Make sure that the tools and equipment are serviceable before you use them.
4) Calibrate gauges before you use them. Also, calibrate gauges at regular
intervals.
5) Do regular checks of hydraulic tools to make sure they are serviceable.
6) Apply protection to the running surfaces and sealing faces of parts that were
removed to prevent damage.
7) When pipes are removed, dirt can go into the openings. Apply protection to the
openings in the pipe and the removed item.
8) Before you start the engine, make sure that repaired parts, replaced parts, or
parts that had an overhaul are serviceable.
9) Make sure that all pipes that were removed and installed are tightened correctly.
10) Do regular checks of parts that move. If the maximum permitted value is the
same or more than that given in 0330 − 1 Clearance Tables, the parts must be
replaced.
11) Use spare parts from the spares stock on board. When you order new parts, get
the code numbers and description from the Spare Parts Catalog.
12) When you tighten nuts, bolts or screws, make sure that you do not cause
damage to the thread. Turn the nut, bolt or screw with your hand until the metal
parts touch. Use only the specified lubricants on the threads.
13) Where torque values are shown, refer to the data given in 0352 − 1 and 0352 − 2 .
14) Devices that lock nuts, bolts etc must be correctly installed. Use lockwire, tab
washers and lock plates once only.
15) For threads of screws and studs in very hot areas, (e.g. exhaust pipe or
turbocharger) apply a lubricant that is resistant to high temperatures before
assembly. This will help when it becomes necessary to remove these items.
16) Always replace O-rings during an overhaul of components, or during removal and
installation procedures. The O-rings must be of the correct dimensions in
accordance with Wärtsilä Services specifications.
17) The installation of piston sealing rings and rod seal rings must be done carefully
to prevent deformation and distortion. Before installation, put the rings into very
hot water.
