Inner Tube, Outer Tube Inspection
Visually inspect the inner tube [A], and repair any dam-
Nick or rust damage can sometimes be repaired by using
a wet-stone to remove sharp edges or raised areas which
cause seal damage.
If the damage is not repairable, replace the inner tube.
Since damage to the inner tube damages the oil seal,
replace the oil seal whenever the inner tube is repaired
If the inner tube is badly bent or creased, replace
Excessive bending, followed by subsequent
straightening, can weaken the inner tube.
Temporarily assemble the inner tube [A] and outer tube
[B], and pump [C] them back and forth manually to check
for smooth operation.
If you feel binding or catching, the inner and outer tubes
must be replaced.
A straightened inner or outer fork tube may fall in
use, possibly causing an accident resulting in seri-
ous injury or death. Replace a badly bent or dam-
aged inner or outer tube and inspect the other tube
carefully before reusing it.
Dust Seal Inspection
Inspect the dust seal [A] for any signs of deterioration or
Replace it if necessary.
Spring Tension Inspection
Since a spring becomes shorter as it weakens, check its
free length [A] to determine its condition.
If the spring of either fork leg is shorter than the service
limit, it must be replaced. If the length of a replacement
spring and that of the remaining spring vary greatly, the
remaining spring should also be replaced in order to keep
the fork legs balanced for motorcycle stability.
