Overhaul TRD 2-way Limited Slip Differential (LSD) for Toyota Corolla AE86 Levin / Trueno
12th April 2004 Monday
Part 4 of 4
After the clutches are removed the top piece / cover case (2nd case = internal case) is removed and placed on the left of the picture below. Again flipped upside down upon removal.
Then the top gear, which was previously under the top piece / cover (2nd case = internal case) is removed and placed on the right of the picture below. This piece is the one directly connected to the drive shaft. Notice the much smaller teeth in the center vertically.

Finally the 4 pinions and gears
So, now I know how LSD works.
If we looks at the top picture and start to imagine things from the drive shaft, which is directly connected to one of the gear,
which upon turning - force the 4 smaller gears to turn,
which forces the cross-bar to push the 2 case opposite,
which forces the case to push against the clutches,
which forces the clutches to push against the cone springs / washers
which forces the cone springs / washers to push against the outer main case
finally all this action forces the two drive shaft to turn in syncronisation.
Everything start from the cross-bar end pushing the 2 case opposite.
