Clutch Plate, Wear, Damage Inspection
Visually inspect the friction and steel plates for signs of
seizure, overheating (discoloration), or uneven wear.
Measure 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
2.72 ∼ 2.88 mm (0.107 ∼ 0.113 in.)
Service Limit: 2.4 mm (0.094 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
0.15 mm (0.0059 in.) or less
Service Limit: 0.3 mm (0.012 in.)
Clutch Spring Free Length Measurement
Measure the free length of the clutch springs [A].
If any spring is shorter than the service limit, it must be
Clutch Spring Free Length
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 clutch hub splines [B].
If there are notches worn into the splines, replace the
clutch hub. Also, replace the steel plates if their teeth are
64.6 mm (2.54 in.)
61.6 mm (2.43 in.)
