CHECKING THE CLUTCH PLATES

The following procedure applies to all of the
clutch plates.
1. Check:
• Clutch plate
Damage → Replace the clutch plates as a
set.
2. Measure:
• Clutch plate warpage
(with a surface plate and thickness gauge "1")
Out of specification → Replace the clutch
plates as a set.
Thickness gauge
90890-03180
Feeler gauge set
YU-26900-9
Clutch plate thickness
1.90–2.10 mm (0.075–0.083 in)
Warpage limit
0.10 mm (0.0039 in)
TIP
The clutch plate thickness specification listed
above is for the plates with the standard thick-
ness only. If a clutch plate with one of the other
two plate thicknesses is installed, use 1.50–1.70
mm (0.059–0.067 in) or 2.50–2.70 mm (0.098–
0.106 in) for the specification according to the
plate.
3. Measure:
• Total width "a" of the friction plates and clutch
plates
Out of specification → Adjust.
Total width of the friction plates
and clutch plates
45.5–46.1 mm (1.79–1.81 in)
TIP
• This step should be performed only if the fric-
tion plates and clutch plates were replaced.
• To measure the total width of the friction plates
and clutch plates, combine 9 friction plates and
9 clutch plates as shown.

the clutch plate "1" first. After replacing the clutch
plate "1", if specifications cannot be met, replace
the clutch plate "2".
