REPLACING SEALS
AND BUSHES
To ensure
maximum
efficiency of
the suspension
and therefore a greater duration
and
safety,
every
10,000
km
it
is
necessary
to replace
all
the seals
and
slide
bushes.
CAUTION;
The
operations
sequence
shown
in
the
draw-
ings in the following
paragraph
refer to the
disassembly and reassembly of the
left
arm.
It
is
fundamental
to
remember
that the
parts
dis-
assembled from
this
arm
should be reassem-
bled
on
it
and
not
on
the right arm, since
-
as
it
is
possible to note
when
disassembling the
arms, the
adjustment rod
of
the
left
arm cap
bolt
is
much
shorter than the
one on
the
right
arm.
Remember
also that
the cartridges are
differ-
ent.
Be
careful
not
to
confuse
them
at
the
reassembly
stage.
