Maintenance
Cleaning the parts
All of the parts must be cleaned with special
biodegradable solvents and dried with compressed air.
Proceed with the cleaning process of all the parts
B
before disassembling them as well as after the partic-
ular parts have been disassembled. Clean each part
even before reassembling.
Connections
In order to allow the motor to function in the best con-
ditions it is absolutely necessary that all of the connec-
tions meet the standards established by the manufac-
turer. A connection with reduced standards could
cause seizing, while a connection with excessive toler-
ation causes vibrations which accelerate the wear of
the components.
General norms for assembling the parts
For reassembling invert the disassembling procedure,
paying careful attention to the specified procedures.
Gaskets, oil spill protector, metallic locks. Tightening
rings in deformable material and self blocking nuts
must always be substituted.
The bearings are dimensioned for a determined num-
ber of working hours. Substitution is therefore recom-
mended in consideration of the difficulty in checking
wear. The above mentioned is in addition suggested
for dimensional controls of the single components
mentioned in the relative paragraphs.
It is absolutely necessary to carefully clean all of the
components; the bearings and all of the other parts
subject to wear must be lubricated with motor oil before
reassembling. Nuts and screws must be locked to the
pre established torques.
Following are the descriptions of the disassembling,
revision and reassembling procedures of the various
parts and sub parts constituting the motor, in the final-
ized sequence of a completely disassembled motor.
Disassemble the motor from its frame as described in
the relative paragraph;
Drain the oil from the oil cup;
Remove the spark plugs covering the openings with
clean rags to avoid small objects (rings, etc.) from
falling into the motor.
