Montero SR 4WD V6-3.5L SOHC (1997)
A. Screw removal. (1)
1. Loosen the screws of the differential cases (A) and (B) uniformly a little at a time.
2. Separate differential case (A) from differential case (B).
3. Remove the components from differential case (B).
NOTE: Keep the right and left thrust washers, spring plates, spring discs, friction plates and friction discs separate in order to be able to
distinguish them for assembly.
Inspection
CONTACT AND SLIDING SURFACES OF PARTS
1. Check the friction plate, friction disc, spring plate and pressure ring.
A. Friction surfaces of friction plate, friction disc and spring plate.
If there are any signs of seizure, severe friction or color change from the heat, it will adversely affect the locking performance. Replace the part
with a new one.
NOTE: The strong contact on the inner circumference of the friction surfaces is because of the spring plate. This wear is not abnormal.
B. Six projections on inner circumference of friction disc If there are nicks and dents, it will cause abnormalities in the clutch pressure.
Use an oil stone to repair the parts. If the parts cannot be repaired, replace them.
C. Four projections on outer circumference of friction disc.
If there are nicks and dents, it will cause abnormalities in the clutch pressure.
Use an oil stone to repair the parts. If the parts cannot be repaired, replace them.
D. Friction surface of pressure ring friction disc.
If there are nicks and scratches, repair the part by first grinding with an oil stone and then polishing with rubbing compound on a surface plate.
NOTE: The strong contact on the inner circumference of the friction surface is because of the spring plate. This wear is not abnormal.
