DISC AND PLATE
1. Clean the discs and plates in suitable solvent and blow dry with
compressed air.
2. Inspect discs and plates for wear, nicks and burrs.
3. To test if friction disc or plate is not distorted, place it on a sur-
face plate and rotate it by hand with indicating ®nger of dial
gauge resting against disc or plate surface.
Allowable warpage:
0.08 mm (0.0031 in)
If it exceeds limits, replace with a new plate to eliminate possi-
bility of clutch slippage or sticking.
4. Measure frictional surfaces and projected portions of friction
disc, friction plate, spring plate, and determine each part's dif-
ferences to see if the speci®ed wear limit has been exceeded.
If any part has worn beyond the wear limit, and deformed or
fatigued, replace it with a new one that is the same thickness
as the projected portion.
Wear limit:
0.1 mm (0.004 in) or less

(3) Install pinion mate gears, side gears and pinion mate shaft in
differential case B.
(4) Set dial indicator's tip on the side gear, and read the indication.
Example:
E = A þ D = A þ (B + C) = 0.05 to 0.15 mm
A = 49.52 mm
B = 19.45 mm
C = 29.7 mm
D=B+C E=AþD
B .... 19.45 A ..... 49.52
+C .... 29.7 þD .... 49.15
49.150.37
From the above equation, end play of 0.37 mm exceeds the speci-
®ed range of 0.05 to 0.15 mm.
Select suitable discs and plates to adjust correctly.
Assembly
Assemble differential case in the reverse order of disassembly,
observing the following.
1. As an aid to installation, apply sufficient amounts of recom-
mended limited slip differential gear oil (refer to MA section) to
the faces of pressure rings, discs and plates to be assembled
together.
2. Place differential case B on a level surface, then install thrust
washer.
3. Install spring plates, friction plates and friction discs.
Pay particular attention to the direction of clutch plates and
their assembly sequence.
