The standard setting of length [A], total thickness of clutch plates shown in the illastration,
becomes about 40.7 mm. For this setting the effective stroke of clutch spring plate during
the back-torque limiter operation is adjusted between 0.45 and 0.75 mm. By increasing
the effective stroke the back-torque limiter causes more slip. The effective stroke
increases by decreasing the length [A]. The length [A] between 39.5 and 40.7 mm is
available by changing the combination of the steel plates. Replace one steel plate with a
thinner one and try the setting. If the operation of the back-torque limiter is not enough
replace other steel plates one by one.
* Steel plates of former model’s are available.
