Inspection Procedure
1. Clutch Cover Check the diaphragm spring tip for wear and height
unevenness.
Check the pressure plate surface for wear, crack and
discoloration.
Check the strap plate rivet for looseness and replace
the clutch cover if loosened.
Unevenness Limit 0.8 mm
2. Clutch Disc Check the facing for rivet looseness, excessive runout,
sticks, oil and grease.
Measure the rivet head depth. If out limit, replace the disc.
3. Clutch Release Bearing The release bearing is permanently lubricated and
requires no cleaning.
Check the bearing for sticks, damage, abnormal noise,
turning drag and wear.
4. Release Fork If there is abnormal wear in contact point with bearing,
replace the release fork.
Wear Limit 0.3 mm

MAINTENANCE AND REPAIR ON-VEHICLE SERVICE MAINTENANCE OF TRANSFER CASE LUBRICANT Oil Level Check Clean the oil level plug and surrounding area.
Remove the oil level plug and check whether oil is drip out or not.
Tighten the oil level plug.
Oil Change Clean the oil level plug and surrounding area
Place a suitable container under the transfer case.
Remove the oil and tighten the drain plug.
Fill the oil through the oil level plug until oil begins todrip out.
Tighten the oil level plug.
Cautions for oil level check and plugs tightening Do not use an impact wrench to remove or tighten theoil level plug or drain plug since this will damage thethreads in the transfer case.
Tightening Torque 20 - 30 Nm

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.
