CHAPTER
ONE
GENERAL
INFORMATION
This
manual
provides
maintenance
informa
tIon
on
the
Datsun
510
Series
and
521
Series
of
vehlcles
The
510
Series
includes
the
two
door
sedan
four
door
sedan
and
station
wagon
The
521
Senes
IS
the
pIck
up
truck
Coverage
is
from
1968
through
1972
models
All
models
use
the
L16
engme
a
96
horse
power
four
cylmder
overhead
camshaft
design
The
510
has
a
fully
synchronized
four
speed
manual
or
three
speed
automatic
transmisSIon
The
521
has
a
four
speed
manual
transmission
only
In
1972
horsepower
ratIng
was
lowered
to
92
horsepower
due
to
changes
m
emission
control
device
requirements
Figure
1
is
an
over
all
view
of
the
four
door
sedan
Figure
2
shows
the
station
wagon
and
Figure
3
illustrates
the
pick
up
truck
Over
the
years
the
510
and
521
series
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
