tool, and torque the derailleur anchor bolt
(B,
Figure 2
) to the specification in Table 5.
Make sure the inner wire still sits in the
pinch-mechanism groove.
13. Cut the excess from the inner wire.
Leave a couple of inches for future adjust-
ment.
14. Fit a new cable ferrule (A,
Figure 2 )
over the inner wire end, and crimp the fer-
rule in place.
15. Install the battery and battery cap
(Chapter Seven).
16. Install the shifter onto the handlebar as
described in this chapter.
17. Adjust the derailleur and then the
cable tension as described in this chapter.
DERAILLEUR
Derailleur Lubrication
Lubricate to the following components
on the derailleur. See Figure 10 .
1. Each edge of the pulley-wheel dust
cap.
2. Both ends of each pivot on the par-
allelogram.
3. The mounting bolt treads.
4. The barrel adjuster threads.
5. The anchor bolt treads.
Derailleur Adjustment
Three screws are used to adjust the derail-
leur. The H-screw (high-gear limiter screw)
sets the outward limit of the derailleur’s
movement. The L-screw (low-gear limiter
screw) sets its inward limit. The B-screw
adjusts the distance between the bottom
of the cogset and the derailleur’s guide
pulley.
A fourth–hand tool (Park Tool BT-2) is
required to perform this procedure
1. Check the cable attachment to the
derailleur pinch mechanism.
a. Check the position of the inner wire in
the pinch mechanism. The wire should fol-
low the groove in the pinch plate, and the
pinch plate tab should be inboard of the
wire when you look directly at the pinch-
mechanism stud (
Figure 9
).
6. Check shifter operation by pulling the
wire and turning the shifter. The inner wire
should move in and out, and the shifter
should click.
7. Insert the inner wire through the ferrule in
the upper end of the cable housing. Feed
the wire through the housing until the wire
emerges from the housing end at the
derailleur.
8. At the shifter, slide the upper housing
along the inner wire, and seat housing fer-
rule in the barrel adjuster.
9. Install the cover (A,
Figure 3 ) and twist
grip (B) onto the shifter.
10. At the derailleur, insert the inner wire
through barrel adjuster and through the
cable pinch mechanism. Make sure the
lower cable ferrule seats in the derailleur
barrel adjuster (C,
Figure 2 ) and the inner
wire is properly routed through the pinch
mechanism.
11. Manually tighten the anchor bolt (B,
Figure 2 ) so the inner wire is secured in the
pinch mechanism groove. Look directly at
the pinch mechanism. The tab on the
pinch plate should be inboard of the inner
wire as shown in
Figure 9
.
12. Loosen the anchor bolt. Pull the slack
from the inner wire with the fourth hand
