ADJUSTMENT OF
THE
RACK
DAMPER
This is
provided
to
ensure
the
required
amount
of
damping
In
the
steering
tie-rods,
and
to
maintain
the
minimum
of
backlash in
the
gear
teeth.
This
should
_be
adjusted
in
the
followlng
manner
:-
Check
the
damper
spring, which
should
have a free
length
of
approximately
1·024 in. (26'01 mrn.), and
should
give a load
of
80 lb. (36,3 kg.)
when
compressed
to
·75 in. (19,05
mm.).
When
the
steering
gearbox
is
completely
assembled,
fit
the
plunger,
spring
and cap,
but
omit
the
shims.
Screw
down
the
cap until
the
plunger
bottoms.
While
screwing
down
the
plunger
rotate

and add
to
this
measurement
·051 in. (1·30 rnrn.].

too
tight,
it is
permissible
to

to
·030 in. (·76 mm.)
or
increase
