4.To measure the thickness "d" of
the plate package (with 2.0 mm
thick outer plates, but without
disk springs), hold the plate pack-
age lightly in a vise and measure "d"
with a micrometer.
Example: d = 76.40 mm.

5.To determine "e" (must be equal
to 5.20 mm) e = c - d
Example:
c = 81.60 mm
d = 76.40 mm
e = 5.20 mm

= e = 5.2
mm
Note
If "e" is greater than or less
than specified,
install thicker or
thinner outer plates.
"e" less than 5.20 mm - install

Outer plates of thicknesses 1.9 mn,
2.0 mn and 2.1 mm are available.
6.After assembly, measure the slip
torque with drive applied to one
axial bevel gear and the other
fixed. Clamp a flange with two
screws in the vise and place dif-
ferential in position. Locate
second flange with improvised
connector and turn differential
with a torque wrench. A torque of
10 . ..35
Nm (7.3... 25 ftlb) must be
attained.
