SUSPENSION - STEERING 13
Pull out the stanchion and damper piston.
Be careful not to confuse the left leg's piston and other components with
those of the right because they're not interchangeable.
Left fork (fig. 6).
Right fork (fig. 7).
Stanchion inspection
Place the stanchion on V-shaped supports and check for straightness
error (fig. 8). The real centering error corresponds to half the comparator
reading. Allowed limit: 0.2 mm
Fork spring inspection
Measure the spring's free length (fig. 9).
Free length: 420 ± 2.5 mm
Min. length: 415 mm
Verify that the stanchion and leg don't show signs of abrasions, scratches
and excessive or abnormal wear.
Replace any worn or damaged components.
Oil seal replacement
Remove the oil seal retainer ring and remove the oil seal.
Avoid damage to the leg's internal and external surfaces.
The oil seals may be replaced without pulling the stanchions from the fork
yokes.
Mount the oil seals then retainer ring.
REASSEMBLY
Clean all components with a solvent and dry thoroughly prior to
remounting.
Mount the piston ring, release spring, spring seat, valve and piston collar
(fig. 10).
Insert the piston group in the stanchion and mount the snap ring.
Insert stanchion in leg. Secure leg in a padded vice; place some locking
material to the socket head bolt threads and tighten to the correct torque.
