• Clamp axle with small internal thread
upwards.
• Position small sun gear (12) with crown
gears to the front.
• Position thrust block (17) in the slotted
hole (is laterally guided when the sun
gear is mounted).
• Locate bolt (16), then spring (15) in the
axle and screw in grey grub screw (14)
until it is flush with the axle end.
• Clamp other axle end. Fit large sun gear
(13). Position conical compression
spring (18), with the large diameter first.
Compress spring and fit washer (19) and
retaining washer (20).
• Assemble cover (21), compression
spring with 7 turns (22) and the second
cover (23, insides to the spring).
• Compress spring and position thrust
block (24) (it is the same both sides) in
the center of the slotted hole.
• Position coupling gear (25) with carrier
plate facing downwards.
• Fit cover (28, inside to the spring) for
compression spring.
• Position gear ring (26) over the teeth of
the coupling gear.
• Place ball retainer (30), with balls below
on the gear ring.
• Position large compression spring (27)
on gear ring.
• Mount compression spring with 13 turns
(29) on the axle. (Is supported in the
coupling wheel by the cover.)
• Locate driver (31), press it down and
screw on fixed cone (32). Tightening
torque 20 Nm.
• Clamp other axle end.
• Push on thrust washer (11) and fit
planetary gear carrier (10). In doing this:
Position mounting aid
(Fig. 2) on the
planetary gear carrier so that the (X)
markings on the three planetary gears
match with the mounting aid.
• Insert planetary gear carrier, place
thrust washer (9) and mount circlip (8) in
recess.
Remove the mounting aid.
Advice:
If the gears are not accurately installed
the hub may be tight to move.
This could lead to damage to the gear-
wheels in operation.
• Mount hub shell (7), with a slight
counterclockwise turn.
• Fit plate (6) and 2 washers (5).
• Screw on counternuts (2+1), tightening
torque 15 – 20 Nm (133 – 177 in.lbs.).
• Reassemble electric drive.

Dismantling shifter cable:
• Place shifter in gear position “1“.
• Do not remove the Clickbox from the axle
end.
• Unscrew the adjusting screw (1, Fig. 3)
completely. Unscrew the cover screw (2),
brush aside the adjusting screw (1) and
remove the cover (3).
• Withdraw shifter cable and clamping
bolt (1, Fig. 4) upwards, loosen clamp
and pull clamping piece from the cable.
• Slightly lift the grip cover (Fig. 5) , push
the cable out and discard.
Assembly shifter cable:
• Route new cable through shifter housing
and pull cable to seat cable head
completely into cable recess.
Feed the cable through the new cable
housing and adjusting screw.
• Position clamping bolt (1, Fig. 6) at a
distance of 80 mm, tighten up with
1.5 Nm (13 in.lbs.) and cut off cable ends
to 2 – 3 mm. For positioning the clamping
bolt use adjust gauge
(Fig. 7) . (Part. No.
65 0324 107 000)
• Locate clamping bolt (1, Fig. 4) and place
shifter cable around the carrier cylinder
(counter-clockwise winding).
• Position the cover (3, Fig. 3) and tighten
up with the cover screw (2).
Torque 0.35 – 0.45 Nm (3.1 – 4.0 in.lbs.).
Screw in the adjusting screw (1)
completely.
Advice:
• If you want to remove the Clickbox from
the axle end for changing the cable, do
as follows:
– Place shifter in gear position “1“.
– Loosen the knurled screw and pull the
Clickbox off the axle.
– Now it’s essential to push the end (1,
Fig. 7) of the adjust gauge completely
into the Clickbox and tighten up the
knurled bolt (so that you maintain the
initial tension of the spring inside the
Clickbox).
– Change cable as per description
above.
• If you remove the Clickbox from the
axle and change the cable without
using the end of the adjust gauge, then
you will lose the initial tension of the
spring inside the Clickbox. In this case
you must assemble the cable by placing
it around the carrier cylinder with an
additional winding (Fig. 4).
A D J U S T M E N T
• Be sure to reset rotational shifter from
4th to 3rd gear.
• Match up the marks in the Clickbox
viewing window (Fig. 3) by turning the
adjusting screw (1).
