Checking The Components - APRILIA RST mille Futura 2001 Service Manual

7.8.4 CHECKING THE COMPONENTS

LOWER FORK TUBE
Inspect the sliding surface to make sure it is not
scratched or scored.
Slight scratches may be eliminated by sanding with
very fine (1200 grit) wet sandpaper.
If the scratches are deep, replace the tube (1).
Use a dial indicator to make sure any bending in the
fork tube (1) is less than the acceptable limit.
If greater than the limit, replace the fork tube.
Bending limit: 0.008 in (0.2 mm).
DANGER
NEVER try to straighten a bent fork tube. This can
weaken the tube, and
unexpectedly. Replace bent tubes. If this happens,
control of the vehicle surely will be lost, and
inevitably followed by an upset and accident, with
serious injury or even death.
UPPER FORK TUBE
Make sure it is not damaged and/or cracked; if so,
replace.
SPRING
Make sure the spring (2) is intact, and that its length is
within the prescribed limit.
If the length does not match the prescribed limit,
replace the spring (2).
Minimum free length of the spring: 9.76 in (284 mm)
Check the status of the following components:
- slider bushing (3);
- guide bushing (4);
- damper (5).
Should you find any signs of excessive wear or damage,
replace the component in question.
NOTE
Carefully clean the wearing surfaces of the
bushings, being careful not to scratch the surface. Any
embedded foreign matter must be gently removed.
Replace the following components with new ones:
- gasket (6);
- dust seal (7);
- the two O-rings on the regulator (8).
