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
2.92 ∼ 3.08 mm (0.115 ∼ 0.121 in.)
Service Limit: 2.7 mm (0.11 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 (0.01 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
44.2 mm (1.74 in.)
Service Limit: 42.8 mm (1.69 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.
