Spring Plate Free Play Measurement
Insufficient clutch free play will cause the engine braking
effect to be more sudden, resulting in rear wheel hop. On
the other hand, if the free play is excessive, the clutch lever
may feel "spongy" or pulsate when pulled.
Hold an extra drive shaft in a vise and install the following
clutch parts on the shaft.
Needle Bearing [B]
Clutch Housing [D]
Clutch Hub [F]
Sub Clutch Hub [G]
Friction Plates [H]
Steel Plates [I]
Spring Seat [K]
Spring Plate [L]
Engage the clutch hub with the sub clutch hub.
To measure the free play, set a dial gauge [A] against the
raised center [B] of the clutch spring plate.
Move the clutch housing gear back and forth [C]. The dif-
ference between the highest and lowest gauge readings
is the amount of free play.
Drive Shaft [D]
Measure the spring plate free play.
Spring Plate Free Play
0.05 ∼ 0.55 mm (0.002 ∼ 0.022 in.)
If the free play is not within the usable range, change all
of the friction plate.
