INSTRUCTIONS
If any service problems occur always refer to
the fault diagnosis chart in the first instance.
Problems can usually be correctly by the
routine external maintenance described in
Part 2. If the problem persists a close
inspection of the working parts inside the
hub will be necessary by a qualified cycle
mechanic.

2.3 Hub Bearing Adjustment
The right hand cone is preset at the
Sturmey-Archer factory and should only be
disturbed during a major service. The
left-hand cone only is used for normal
bearing adjustment.
1. Loosen left-hand cone locknut.
2. Adjust brake arm nut until very slight
side play can be felt at the wheel rim, and
none at the hub.
3. Holding the brake arm nut stationary
tighten the cone locknut (Torque 27 Nm).
4.1 Disassembly
NB: Item numbers in the illustrations refer to
exploded view overleaf.
1. Remove the indicator rod, axle nuts and
spacing washers.
2. Use a screwdriver carefully to release the
sprocket circlip from the drive, and then
remove the spacing washers (if any),
sprocket (note the order of these parts to
facilitate reassembly).
3. (See Fig.1) Clamp right hand end of axle
in a vice and unscrew the left hand cone
locknut, and brake arm nut. Remove the
left hand cone, brake arm assembly, and
brake shoes. Remove the brake actuator
assembly by turning hub-shell clockwise.
Remove hub from vice.

4. Loosen the right hand ball ring and
dustcap assembly with a C-spanner or
hammer and punch. Unscrew the ball ring
to release the internal assembly from the
hub shell.
NB: If a replacement gear internal assembly
(Item 60 on exploded view) is to be fitted, no
further disassembly is required.
5. See (Fig.2). Clamp the left hand end of
axle in the vice and remove right hand
cone locknut, spacers (if any), lockwasher,
cone and spring with cap. Lift off ball
ring and ball cage assembly, together with
the driver assembly. Separate the driver
assembly from ball ring by compressing
pawls and extracting the driver assembly
through ball ring.

readily, but have high resistance to turning
anti-clockwise.
7. Brake shoe segments - Replace if worn.
8. Left hand cone - Condition of ball track.
9. Brake Arm - Replace if damaged.

6. (See fig. 3). Lift off gear ring assembly,
clutch and axle key. Remove planet
pinion pins and axle key. Remove axle
from vice.
4.3 Assembly
NB: All hub greases must be replenished
during assembly using lubricants to the
following Sturmey - Archer Technical
Standards:
For Bearings SA103B
For Brake Parts SA103E
For all other internal parts SA103A
If a complete replacement gear internal
assembly (Item 60 on Exploded View) is to
be fitted, assembly commences at Point 5
below:
1. Locate planet cage over the axle with
external screw thread facing away from
axle slot. Screw first locknut down until
finger tight. Slacken off 1/8 of a turn
allowing free running of the planet cage
with minimum axial movement. Hold the
first locknut in place and screw down the
second one to lock against it.
2. (See Fig. 3). Clamp left hand end of axle
in vice and fit the planet pinions and pins
vertical), clutch and gearing assembly.
3. (See Fig. 2). Fit the ball ring assembly
then driver assembly compressing pawls
to ensure driver ball track seats correctly
on ball ring. Fit spring then cap.
4. Screw down the right-hand cone finger
tight. Unscrew the cone by half a turn. Fit
the cone lockwasher. If the washer will

7. (See Fig. 1) Fit ball cage assembly, with
balls facing down. Fit left hand cone,
lining up the slot on the underside of the
cone (See Fig. 5) with the brake actuator
drag spring tag. Slide over the axle to
engage tag, checking the cone is correctly
seated by rotating slightly ensuring that it
engages with the brake shoes (see Fig. 5).
Fit brake arm assembly, brake arm
locknut and locknut. Adjust hub as
described in Part 2. Remove hub from
vice.
8. Assembly dustcap, sprocket and circlip in
