Clutch
Clutch Plate, Wear, Damage Inspection
• Visually inspect the friction and steel plates for signs of
  seizure, overheating (discoloration), or uneven wear.
• Measure
  points.
            the thickness of each friction plate [A] at several

  If any plates show signs of damage, or if they have worn
  past the service limit, replace them with new ones.
  Friction Plate Thickness
    Standard:        2.72  2.88 mm (0.107  0.113 in.)
    Service Limit:   2.5 mm (0.10 in.)

Clutch Plate Warp Inspection
• Place each friction plate or steel plate on a surface plate
  and measure the gap between the surface plate [A] and
  each friction plate or steel plate [B] with a thickness gauge
  [C]. The gap is the amount of friction or steel plate warp.
  If any plate is warped over the service limit, replace it with
  a new one.
  Friction and Steel Plate Warp
    Standard:        0.15 mm (0.0059 in.) or less
    Service Limit:   0.3 mm (0.01 in.)

Clutch Housing Finger Inspection
• Visually  inspect the clutch housing fingers [A] where the
  friction plate tangs [B] hit them.
  If they are badly worn or if there are groove cuts where the
  tangs hit, replace the housing. Also, replace the friction
  plates if their tangs are damaged.

Clutch Housing Spline Inspection
• Visually inspect where the teeth [A] on the steel plates
  wear against the sub clutch hub splines [B].
  If there are notches worn into the splines, replace the sub
  clutch hub. Also, replace the steel plates if their teeth are
  damaged.
