6.9b Bearing adjuster nut
this Chapter. Now slacken the nut, and tighten
it to the final torque setting specified (see
illustrations).
10 If the special tool is not available, using
either a C-spanner, a peg spanner or a drift
located in one of the notches, loosen the
adjuster nut slightly to take pressure off the
bearings then tighten the nut until all freeplay
is removed. Now tighten the nut a little more to
pre-load the bearings. Now loosen the nut and
retighten it, setting it so that all freeplay is just
removed from the bearings, yet the steering is
able to move freely from lock-to-lock.
11 Turn the steering from lock-to-lock five
times to settle the bearings, then recheck the
adjustment or the torque setting. The object is
to set the adjuster nut so that the bearings are
under a very light loading, just enough to
remove any freeplay.
Caution: Take great care n o t to apply
excessive pressure because this will cause
premature failure o f the bearings.
12 With the bearings correctly adjusted and
where only one locknut is fitted, install a new
lockwasher ensuring two of the tabs locate in
notches in the adjuster nut. Install the locknut
finger-tight, then hold the adjuster nut to prevent
it tuming and tighten the locknut securely. If the
special tool is available, tighten the locknut to
the specified torque setting. Bend the remaining
lockwasher tabs up to secure the locknut.
13 Where two locknuts are fitted, install the
rubber washer and then the lower locknut,
tightening it finger-tight. Hold the adjuster nut to
prevent it tuming, then tighten the lower locknut
only enough to align its notches with the
6 . 9 ~ Adjusting the steering head bearings
with the special tool and torque wrench
notches in the adjuster nut and install the tab
washer (see illustration 6.8~1). Install the upper
locknut, then hold the adjuster nut to prevent it
tuming and tighten the upper locknut securely. If
the special tool is available, tighten the locknut
to the specified toque setting (see illustration).
14 Check the
bearing adjustment
as
described above and re-adjust if necessary,
then install the remaining components in the
reverse order of removal.

Removal
1 Refer to Chapter 8 and remove the front
wheel and the brake caliper. On Speedfight
models, if required, remove the front mudguard
and the wheel hub. On Vivacity models, remove
the front mudguard. On Speedfight 2 Furious
and Metal-X Furious models, ensure the lower
end of the speedometer cable is detached from
the front suspension (see Chapter 9).
2 Remove the handlebars (see Section 5). On
Speedfight 2 Furious and Metal-X Furious
models, remove the bolt securing the instrument
cluster bracket and displace the instrument
cluster. Unscrew the nut on the steering stem
bolt and remove the nut, washer and shaped
spacer, noting how they fit. Withdraw the bolt
and lift off the handlebar bracket.
3 On Trekker models, remove the mudguard
liner from the underside of the steering stem
(see Chapter 7).
6.13 Hold the adjuster nut and tighten the
locknut with the special tool
4 Although not essential, it is advisable to
remove adjacent body panels to avoid the
possibility of damaging any paintwork (see
Chapter 7). Note: The ball bearings in the
lower steering head race are not retained by a
cage
-
place a clean rag on the floor beneath
the steering head to catch the ball bearings
when the steering stem is removed.
5 Unscrew and remove the bearing adjuster
locknut(s) and washer (see Section 6).
6 Support the steering stem, then unscrew
the bearing adjuster nut and carefully lower
the steering stem out of the steering head
(see illustration). Note which way round the
adjuster nuts fits -the top inner race is on the
underside of the adjuster nut.
7 The ball bearings in the lower race will either
fall out of the race or stick to the lower inner
race on the steering stem. The top bearing will
remain in the top of the steering head.
8 Remove all traces of old grease from the
ball bearings and races and inspect them for
wear or damage (see Section 8). Note: Do not
attempt to remove the outer races from the
steering head or the lower bearing inner race
from the steering stem unless they are to be
renewed.
Installation
9 Apply a liberal quantity of grease to the
bearing inner and outer races and install the
top bearing
(see
illustration).
10 Assemble the lower race ball bearings on
the lower inner race on the steering stem; they
will be retained by the grease (see illustration).
Note that there are 21 balls in the lower race.
7.6 Lower the steering stem out of the
steering head
7.9 Install the top bearing
7.10 Hold the lower race ball bearings in
place with grease
