Adjustment of Clearance between
Friction Disc and Plate
1) Measuring depth of differential case
mm(in)
Standard (A-B) 80.58 (3.17)
(C) 10.58 (0.41)
2) Measuring overall length of pressure ring, friction disc and
plate assembly
Assembly pinion shaft with pressure ring, then friction
disc and plate.
Measure length between plates at both ends over V-
shape groove. (D)
3) After A, B, C and D dimensions are measured, perform
adjustment with the following procedure.
Measure disc spring :
1.75 mm (0.69 in)
2 pcs (E)
Measure thickness of plate spring
Standard dimension :
1.75 mm (0.069 in)
2 pcs (F)
4) Select a friction disc or plate so that ((A-B+C) - (D+E+F) =
0.06 to 0.20 mm (0.002 to 0.008 in.) and also the difference
in total dimension of friction disc and plate, plate spring and
disc spring (left/right side) does not exceed 0.05 mm (0.002
in.).

Important Operation - Installation
1. Weather Strip ; Rear Window Corner
Using Semedain #560 (or equivalent) adhesive, glue the
weather strip to the complete circumference of the frame,
paying close attention to the corner areas.
2. Glass ; Rear Window Corner
Apply soap and water to the rim as a lubricant.
Place the channel in a vertical position. With your hand, apply
pressure to expand the channel. Insert the window glass in the
center of the channel.
3. Glass Run
Apply Semedain #560 (or equivalent) adhesive to the entire
length of both the upper window glass and the weather strip.
Apply adhesive to both sides of the extreme ends of the lower
portion for a distance of about 50 mm.
There should be no gap between the weather strip rear window
glass channel and the channel.
6. Rear Window ; Slide
Hold the window vertically. Apply an upward pressure to the
channel and insert the rear window slide.
8. Packing ; Rear Window
Apply a fast setting adhesive agent to both sides of the window
atop and insert it into the channel.
