FSO-2405 2nd Ed. 02/07 General Information
Housings
Clean interior and exterior of cases, covers, etc., thoroughly. Cast parts may be cleaned in hot
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.
WARNING! 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.
Gears, shafts and synchronizer assemblies
Whenever magna-flux is available, this process should be used to check the parts.
Check carefully gear teeth for wear, pitting, chipping and cracks. If gear teeth show areas
where the case hardening is worn through or cracked, the gear should be replaced.
Check shafts for warping and excessive wear or damaged splines.
Cases, covers, etc.
Make sure cases, covers, etc. are completely clean and that mounting surfaces and bearing
bores are free from nicks or burrs. Check carefully every part for cracks, excessive wear or for
any other condition that may cause oil leak or a future failure.
