Frame and suspension 6.1 1
50 Clean the bottom of the slider and the
inside of the axle/brake caliper bracket and
remove any traces of corrosion.
51 Smear the new oil seal with fork oil, then
fit it over the slider and press it into position
on the bottom of the tube.
52 Smear the inside of the new dust seal with
fork oil and install the seal.
53 Install the axle/brake caliper bracket and
tighten the retaining bolt securely. Use the axle
inserted through the bracket to prevent the
fork slider rotating when tightening the bolt.
54 Install the brake caliper and front wheel
(see Chapter 8).
Disassembly
Note: The forks on these models are diffcult to
disassemble. Also, some models have had
undocumented changes to the internal
components of the fo& and they may differ to
those components described. A cecertai n amount
of reader input and common sense will have to
be applied if the forks are to be disassembled.
Note: Always dismantle the fork legs
separately to avoid interchanging parts.
55 Remove the steering stem (see Section 7).
56 Remove the dust and oil seals
(see Steps 48
and 49).
57 Remove the lower circlip from inside the
bottom of the fork leg, then draw out the lower
bush and remove the upper circlip. Discard
the circlips as new ones must be fitted on
reassembly.
58 Pull the slider out of the fork leg together
with the rebound spring, washer and upper
bush. Drain the fork oil out of the slider.
59 Withdraw the compression spring and
buffer from the leg.
Inspection
60 Clean all parts in a suitable solvent and dry
them with compressed air. lnspect the fork
sliders for score marks, pitting or flaking of the
chrome finish and excessive or abnormal wear.
Check the straightness of the sliders with a
straight-edge. Peugeot do not list the sliders as
separate items. If a slider is worn or damaged a
new fork assembly will have to be fitted.
61 Inspect the springs for cracks, sagging and
other damage. Measure the spring free length
and compare the result to the specifications at
the beginning of this Chapter. If a spring is
defective, renew all the springs as a set.
62 Examine the working surfaces of each bush;
a
worn or scuffed, renew the bushes as a set.
Reassembly
63 Install the various components in the
reverse order of removal. Pour the correct
quantity of the specified fork oil into each
slider before installing the sliders.
64 lnstall the new upper circlip using a suitable
piece of tubing to ensure it is squarely positioned
inside the fork tube, then install the lower bush a
new lower circlip using the same method. Take
care not to scratch the slider. Make sure the
circlips are corr&ly located in their grooves.
Upside-down forks
(Vivacity
50
cc models)
65 The forks on these models are outwardly
similar to the Trekker forks. However, Peugeot
only list replacement oil seals for the Vivacity.
The replacement procedure for the seals is
the same as for the Trekker. If the fork action
is suspect, consult a Peugeot dealer. If the
fork is damaged a new fork assembly will
have to be fitted. To remove the fork, first
remove the steering stem (see Section 7).
Upside-down forks
(Vivacity 100 cc models)
66 The forks on these models are outwardly
similar to the Trekker forks. However, fork
action is controlled by an hydraulic cartridge
in the left-hand tube and a spring in the right-
hand tube, and the forks are maintenance-
free. If the fork action is suspect, consult a
Peugeot dealer. If the fork is damaged a new
fork assembly will have to be fitted. To
remove the fork, first remove the steering
stem (see Section 7).
10 Rear shock absorber
removal, inspnmrinn
and installati1
Removal
1 Support the machine
on
its stand and position
a support under the rear wheel so that the engine
does not drop when the shock absorber is
removed, but also making sure that the weight of
the machine is off the rear suspension so that the
shock is not compressed.
2 The shock absorber is secured to the frame
at the top and the transmission casing at the
bottom. To access the nut securing it at the
top, remove the body panels as necessary
according to model (see Chapter 7). Remove
the air filter housing (see Chapter 4).
3 Undo and remove the nut and bolt securing
the top of the shock absorber to the frame.
4 Undo the nut and bolt securing the bottom of
the shock absorber to the transmission casing.
Support the shock and remove the bolt, then
manoeuvre the shock away from the machine.
lnspection
5 lnspect the shock absorber for obvious
physical damage and the shock spring for
looseness, cracks or signs of fatigue. Later
Speedfight 2 and TKR models are fitted with a
remote reservoir shock with adjustable spring
preload (see illustration); use a C-spanner to
ensure the preload adjuster turns freely and
locks in position under spring pressure.
6 lnspect the damper rod for signs of
bending, pitting and oil leakage and check the
mountings at the top and bottom of the shock
for wear or damage (see illustration 9.17).
Individual components are not available for
the shock. If any parts are worn or damaged,
a new shock must be fitted.
lnstallation
7 lnstallation is the reverse of removal.
Tighten the shock absorber mounting bolts to
the torque settings specified at the beginning
of this Chapter.

1 Remove the engine/transmission unit (see
Chapter 2A or 28).
2 Counterhold the engine bracket-to-frame
bolt and undo the nut, then withdraw the bolt
and remove the engine bracket, noting how the
silentblock ffis to the bracket (see illustration).
lnspection
3 Thoroughly clean all components, removing
all traces of dirt, corrosion and grease.
4 lnspect the silentblock closely, looking for
obvious signs of wear such as compression
and cracks, or distortion due to accident
damage. It should be necessary to compress
the silentblock in order to remove and install
the engine bracket-to-frame bolt. If the
bracket is not a tight fit, renew the silentblock.
5 Check the bolts for wear and check the
holes in the engine bracket for wear. If the
bolts are not a precise fit in the bracket the
components must be renewed.
6 Check the condition of the engine mounting
bushes (see Chapter 2A or 28).
