Spring Plate Free Play Measurement (VN1500-N1
Insufficient spring plate 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 may slip or the clutch lever may feel "spongy" or pul-
sate when pulled.
Take care not to damage the drive shaft.
Hold an extra drive shaft [A] steady with a vise and install
the clutch parts on an extra drive shaft.
Do not install the back torque limiter springs [B] and the
operating plate [G].
Tighten the clutch hub nut [C] to about 29 N·m (3 kgf·m,
22 ft·lb) of torque to seat the clutch plates closely.
Unscrew the hub nut, then take the spring holder [E], op-
erating plate, and the clutch spring [D] out of the housing.
Reinstall the clutch spring plate [F].
Reinstall the spring holder [A] and tighten the hub nut [B]
To measure the free play, install the dial gauge [D] against
the clutch spring plate [C].
Set the reading of the gauge "0".
Turn [E] the clutch housing right and left. The difference
[F] between the highest and lowest gauge readings is the
amount of free play.
Spring Plate Free Play
Usable Range: 0.30 ∼ 1.30 mm (0.012 ∼ 0.051 in.)
In case of rear wheel hop, adjust the spring plate free
play a bit larger, and in case of clutch slip, or "spongy"
clutch lever, adjust the free play a bit smaller within the
