1. General Information
Precautions
Precautions during disassembly
and assembly
In order to prevent damage to transmission
parts during initial gear movement,
it is important when assembling the
transmission, to lubricate gear bearings,
needle roller bearings, non sealed
bearings and all other parts under friction
conditions, with the same transmission
lubricant oil.
Multi Purpose Grease
Where specified Multi Purpose Grease use a NLGI
2 lithium based grease with dropping point at 177ºC
minimum.
Cleaning and handling
In order to completely clean the parts, wash them into a
bath of solvent (kerosene, for instance), moving every
part up and down slowly until all the old lubricant and
foreign material have been dissolved.
Care must be taken to avoid skin rashes,
fire hazard and vapor inhalation when
using solvents.
Non sealed bearings
Immerse the bearings in clean solvent. Move them up
and down slowly in order to loosen the deposits. Dry
the bearings by means of moisture free compressedair.
Repeat the operation until the bearings are thoroughly
clean.
Never drive the air jet directly to bearings
in order to rotate them in high speed.
That can damage bearings.
Synchronizer assemblies
Avoid bad handling of synchronizer assemblies. Either
drops or bumps when disassembling or assembling
may cause them to lock.
Housings
Clean interior and exterior of cases, covers, etc.,
thoroughly. Cast parts may be cleaned in weak
alkaline solution baths (we recommend a 7% soluble
degreasing oil solution). The parts are to remain in
the bath for the time it takes to become completely
clean. The parts cleaned in alkaline solutions should
be rinsed with clean water to remove any alkaline trace
after cleaning process.
Care must to be taken to avoid vapor
inhalation and skin rashes when using
alkaline solutions. Every cleaned part
must be totally dried at once by means
of moisture free compressed-air, or else,
by means of a lint free soft cloth, not
containing any abrasive material such
as metal filings, contaminated oil or
polishing compounds.
Inspection
A thorough and careful inspection of each part is very
important for the transmission life. The replacement of
parts showing either wear or fatigue will avoid future
expensive and foreseen failures.
