Important
ï‚· Before proceeding with operations, read Par. 3.3.2 .
ï‚· To easily locate specific topics, the reader should refer to the analytical index or chapter index .
ï‚· The operator must check that:
o the components, the assemblies, the coupling surfaces of the parts are washed, clean and
thoroughly dried;
o the coupling surfaces are undamaged;
o the equipment and tools are ready so that all work can be carried out correctly and safely;
o ensure that the working environment is safe.
ï‚· The operator must:
o carry out the procedures smoothly and safely. It is thus recommended to install the engine
on a special rotating stand used when servicing engines to ensure the safety of the operator
and the other individuals involved;
o tighten the assemblies and / or components in a criss-cross or alternating pattern, initially
with a value lower than that preset, and then subsequently, with the tightening torque
specified in the procedure;
o replace all seal gaskets after each assembly for all components on which they are provided.
