AA" SCREWS REMOVAL
1. Check out the alignment marks.
2. Loosen a uniform amount little by little the screws securing
differential case A to B.
3. Separate differential case B from differential case A and
remove their components.
Keep the removed spring plates, friction plates, and friction
discs organized in the order of removal and for right and
left use.
INSTALLATION SERVICE POINTS
"AA DIFFERENTIAL CASE B INSTALLATION
Before starting the assembly procedure, perform the following
steps to adjust dimensional differences (clutch plate friction
force) in the axial direction of the components inside the
differential case and axial clearance of the differential side
gear.
1. Place friction discs (two each) and friction plates (three
each) one on top of another as illustrated and, using
a micrometer, measure the thickness of each of the right
and left assemblies. Select different discs and plates so
that the difference between the right and left assemblies
falls within the specified range.
Standard value: 0 – 0.05 mm
NOTE
If a new part is used, note that the friction disc comes
in two thicknesses: 1.6 mm and 1.7 mm.
2. Measure the thickness of each of the right and left spring
plates.
3. Assemble the pressure ring internal parts (pinion shaft
and pressure ring), friction plates, and friction discs and,
using a micrometer, measure the overall width.
NOTE
When taking measurements, press the assembly from
both sides so that the pinion shaft makes a positive contact
with the groove in the pressure ring.
4. Find value (A) which is the thickness measured in step
(3) added to the thickness of two spring plates.
