Over
the

years
the
510

have

remained

essentIally
the
same
with
the

excep

tion
of

changes
to
the

emISsion
control

systems

and
overall

body
stylmg
In
this
manual

every

effort
has
been
made
to

pinpoint
significant
c
if

ferences
between
model

years

The
use
of

SpecIal
tools
and
test

equipment

has
been
avoided
wherever

possible
When

necessary
special
tools
and
test

equipment
are

illustrated
either
in
actual
use
or
alone
A
well

equipped
mecharuc

may
find
he
can

substitute
similar
tools
or
make
his

own
to
fulfill
a
e

Ii

ment

Recommendations
are

occasionally
made
to

refer
servIce
or
mamtenance
to
a
Datsun
dealer

or
a

SpecIaliSt
in
a

specIfied
field
In
these
cases

work
WIll

probably
be
done
more

qUlckly
and

economIcally
than
if
the
mecharuc

performs

them
himself
