5D1-22 TRANSFER CASE (PART TIME 4408) Cleaning Procedure Notice Before cleaning, check the magnet for thepresence of metal particles which indicate internalchipping of the transfer case.
1. Using cleaning solvent, clean the residual oil and dirtdeposits.Notice
During cleaning, be careful not to damage the metal surfaces.
2. After cleaning, dry the parts with low pressure (Max. 20 psi) compressed air.
3. Lubricate the ball bearings and needle bearings with transfer case oil after cleaning. NoticeProtect the lubricated bearings from dust.
Inspection Procedure
1. Visually check the all removed parts. Notice
Always replace the hose coupling, O-ring and oil seal with new parts.
2. Inspection Terms Burr : Local rise of material forming protruding sharp
edge
Chip : An area from which a small fragment has been
broken off or cut
Crack : Surface break of line nature indicating partial or
complete separation of material.
Excessive wear : Heavy or obvious wear beyond
expectations considering conditions of operation.
Indentation : Displacement of material caused by localized
heavy contact.
Galling : Breakdown of metal surface due to excessive
friction between parts. Particles of the softer materialare torn loose and welded to the harder material.
Nick : Local break or notch, usually displacement of
material rather than loss.
Scoring : Tear or break in metal surface from contact
under abnormal pressure.
Step wear : Heavy wear that produces a step that can
be seen or felt between adjacent contact and noncontactsurfaces.
Uneven wear : Condition of localized, unevenly distributed
wear Includes hollows, shiny spots, uneven polish and other visual indications.
