9. Check the fork tube (A, Figure 51) for straight-
ness. Refer to Table 3 for maximum runout.
10. Inspect the fork cap bolt threads in the fork tube
(Figure 52) for wear or damage.
11. Make sure the oil hole (Figure 53) in the fork
tube is clear. Clean out if necessary.
12. Check the slider (B, Figure 51) for dents or ex-
terior damage that may cause the upper fork tube to
53
stick.

2. If removed, install a new bushing (Figure 60)
onto the fork tube.
62
NOTE
Place a clinging-type plastic wrap
over the end of the slider and coat it
with fork oil. This will prevent dam-
age to the dust seal and the oil seal
lips when installing them over the top
of the fork tube. The parts can then be
carefully slid over the fork tube and
the plastic wrap without damaging
the seal.
3. Coat the new seal with clean fork oil.
63
NOTE
Position the new oil seal with the open
groove facing upward.
4. Slide the fork slider bushing (A, Figure 61),
spacer (B), oil seal (C), stopper ring (D), dust seal
(E) and cover (F) down into the fork tube.
5. Insert the damper rod cartridge into the fork tube
(Figure 62).
NOTE
The slider bushing opening must be
positioned to either side of the slider
after the fork tube has been installed.
64
Orientate the opening in relation to
the front fender mounting bosses. If
the opening is positioned toward ei-
ther the front or rear of the slider, it
will wear prematurely.
6. Position the slider bushing with the opening
(Figure 63) toward either side of the slider.
7. Insert the fork tube into the slider until the slider
bushing reaches the slider.

ing (A, Figure 64) is correctly located in relation to
the fender bosses (B). Readjust if necessary.
NOTE
A fork seal driver like is required to in-
stall the fork tube bushing and seal into
the fork tube. A number of different af-
termarket fork seal drivers are avail-
able that can be used for this purpose.
Another method is to use a piece of pipe
or metal collar with correct dimensions
to slide over the fork tube and seat
against the seal. When selecting or fab-

seal into the fork tube. A fork seal and
cap installer (JIMS part No. 2046) is
used in this procedure.
9. Slide the fork seal driver down the fork tube and
seat it against the seal (C, Figure 64).
10. Operate the driver and drive the fork slider
bushing, spacer and new seal into the fork tube.
Continue until the fork tube stopper ring groove is
visible above the fork seal (Figure 65).
11. Slide the stopper ring down the fork tube.
12. Install the stopper ring and make sure it is com-
pletely seated in the groove in the fork slider (Fig-
68
ure 66).
13. Install the dust seal into the slider. Index it into
the groove in the slider (Figure 67).
14. Install the cover and carefully tap it into place
(Figure 68).
15. Insert the damper rod cartridge into the fork
tube (Figure 69).

not be installed in Step 16.
16. Insert a scribe or thin screwdriver into the hole
in the base of the slider to guide the lower end of the
damper rod cartridge into the lower stop in the base
of the slider.
NOTE
If the damper rod cartridge rotates
while tightening the Allen bolt, tem-
porarily install the fork spring and the
cap bolt to hold it stationary.
17. Install a new washer on the Allen bolt (Figure
71
70). Install it in the fork slider and tighten to the
specification in Table 1. If installed, remove the cap
bolt and fork spring.
NOTE
The following special tool is usually
part of the fork holding tool. If not so
equipped, one can be fabricated that
is approximately 2 inches long with
an inner metric thread of 12 ×1.0.
This tool is to extend the length of the
damper rod for fork bleeding process.
18. Install the special tool extension (Figure 71)
72
onto the damper rod cartridge.
19. Secure the fork assembly in a vertical position.
NOTE
To measure the correct amount of
fluid, use a plastic baby bottle. These
bottles have measurements in millili-
ters (ml) on the side.
20. Completely compress the fork tube into the
slider.
21. Add one-half of the recommended amount (Ta-
ble 2) of H-D Type E fork oil to the fork assembly
(Figure 72).
73
NOTE
During the bleeding procedure, main-
tain the fork oil level above the sliding
portion of the damper rod cartridge. If
the oil level drops below this level, air
may enter the cartridge, nullifying the
bleeding procedure.
22. Bleed air from the damper rod cartridge as fol-
lows:

FRONT SUSPENSION ADJUSTMENT
(FXDXT, 2000-ON FXDX)
Rebound Damping Force Adjustment
The rebound damping can be adjusted by turning
the knob adjuster on top of the fork cap bolt. The
knob adjuster has 17 positions.
10
The standard adjuster setting is eight turns out
from the base position. Turning the adjuster all the
84
way clockwise results in the stiffer setting, while
turning the adjuster counterclockwise results in the
softer setting.
1. Turn the knob adjuster (Figure 85) in either di-
rection to achieve the desired rebound damping.
2. Turning the adjuster clockwise will increase re-
bound damping.
3. Turning the adjuster counterclockwise will de-
crease rebound damping.
4. Repeat for the other fork assembly. Ensure both
fork legs are adjusted to the same setting.
85
Compression Damping Force Adjustment
The compression damping force can be adjusted
by turning the screw adjuster on the base of the fork
slider. The knob adjuster has 14 positions.
The standard adjuster setting is ten turns out from
the base position.
1. Turn the adjuster (Figure 86) and rotate it in ei-
ther direction to achieve the desired compression
damping force adjustment.
