Secondary drive check up
To check the wear of the secondary drive is necessary to proceed to the visual inspection of the
front sprocket (24) and of the rear sprocket (2). If the teeth profile is shown as in figure (dotted
line) the sprocket must be renewed.
Chain washing
Chains with O-rings must be washed in oil, diesel fuel or paraffin (kerosene).
Do not use petrol, trichloroethylene or other solvents, which could damage the rubber O-rings. For
the same reason use only sprays specifically formulated for use with O-ring chains.
.
Chain lubrication
Chains with O-rings are lubricated and sealed to protect the O-rings themselves against wear in
the pin/bushing area. However, these chains need lubricating at regular intervals to protect metal
parts of the chain and the O rings.
Lubrication also serves to keep the O-rings soft and pliable to ensure the maximum sealing
efficiency.
Using a brush, apply a thin protective film of high-density gearbox oil along the entire length of the
chain both inside and outside.
IMPORTANT
The substitution of the rear sprocket (2) must be done together with the front sprocket (24) and the
chain (3).
