Description
of
system
The
suspension units on each side consist oí a
teles-
copic shock absorber and a coil spring, resting
on
lower
wishbones.
The
coils are mounted above the shock
absorbers
putting
them above the level of the wheels
as
can be
seen
in the
sectioned
view
oÍ
the
suspension in
FIG 8:1.
This
factor allows large wheel
movements on
bounce and rebound which evens out even the roughest
of roads. Radjus arms run from the lower localion
points
of
the
spring
legs
Íorward to
the
chassis where they are
rubber bushed.
These
take braking
Íeactions
and complete
the suspension system.
Toe-in is
the only front end angle
that is
adjustable.
It is necessary
to renew bent
parts
to
re-establish
the
correct angles in the
event of any misalignment.
The wheels
and drums are balanced
both statically
and dynamically
at the
factory
and must
be
marked
before disassembly so that they can
be
replaced
in their
correct Dositions.
8:2
Routine maintenance
At
every
1800
miles lubricate the
grease
nipple on the
lower swivel
and stub axle assembly. Before injecting
grease
clean and examine the nipples for
damage and if
necessafy
renew
the nipples.

for corrosion
and for discoloration resulting from
over-
heating. A light
brown discoloration may
be
due to
