intended. The disassembled parts must be put in the
special container by following the disassembling
sequence, in order to facilitate re-assembling.
Upon re-assembling, the parts must always be
replaced with new ones: the gaskets and seal rings,
elastic pins, safety snap rings and springs. The nuts and
screws must be tightened to the specified torque, and
their threads must be dry, degreased and spread with
LOCTITE 641. The lubricant and detergents must be
disposed of in compliance with the specific
regulations in force.
Overhaul operations must be carried out by means
of the specific tools indicated. On disassembling, parts
must be put aside by following the disassembling
sequence, to facilitate later re-assembling.
