Cleaning the dust seal (FIG. 5)
FUG.5
This operation can be carried out with the fork installed on the mo-
torcycle.
No need special tools.
Use silicone grease spray.
Dismantling
• Carefully clean the stanchion tube ( 6 ) before carrying out this operation.
• With a small screwdriver prize the dust seal ( 12 ) off the slider ( 13 ), without
scratching the stanchion tube.
• Slide the dust seal along the stanchion tube and clean inside the dust seal
and its seat on the slider with a jet of compressed air.
Never use metal tools to clean any particles of dirt.
• Compress the fork legs slightly and remove any traces of dirt from the stanchion
tubes.
• Lubricate the dust seal and the visible surface of the oil seal with silicon
grease.
Re- assembly
• Re- assemble the dust seal ( 12 ) in its seat, pressing it home with your
hands.

Bleeding the air

This operation must be carried out with the fork assembled on the
motorcycle and with the fork's legs fully extended (front wheel off
the ground).
The pressure generated by the air that can get into the fork legs
while the motorcycle is being used and which, due to the special
shape of the oil seals remains trapped inside, can cause the fork to
malfunction.
Dismantling
• Monthly or after every race use a crosshead screwdriver to unscrew the air
bleed screw ( 14 ) in both the fork legs on the top part of the slider, to drain
the pressure that can build up inside.
• Check the state of the oil seal ( 50 ); replace if necessary.
Re- assembly
• Tighten the air bleed screw ( 20 ) to the recommended torque (see Table 1
-Tightening torques), being careful not to damage the oil seal ( 50 ).
