if
this
occurs
it
will
be

necessary
to
set
the
camshaft

to
the
No

can

be
checked

by
turning
the

is
made

by
setting

out
in

the
following
manner

until
all

36

system
should
be
lubricated

every
two

years

or
50
000
km
30
000
miles
whichever
comes

fIrst

A
lithium
base

multipurpose
grease
must
be
used
for
the

rack
and

pinion
and
rack
and
tie
rod

joints
The

plug
on
the

steering
gear
housing
should
be
removed
and
a

grease
nipple

fitted
so
that
the
recommended

quantity
of
10
to

15

gram

0
35
to

0
53
oz
of

grease
can
be

injected
Remove
the

grease

nipple
and

replace
the
plug
when
lubrication
is

completed

The

grease
reservoir
on
the
tube

should
be

replenished
when

the
level
of

grease
falls
to

approximately
