Determine
the
number
of
lines
or
hoses

Knowing
the
number
of
lines
or
hoses
is
helpful
in
identifying

the
gear
part
number.

Vehicles
equipped
with
an
assist
gear

all
have
4
lines
and
many
vehicles
without
an
assist
gear
are

equipped
or
ported
for
4
lines.

If
your
gear
only
has
two
ports
on
the
valve
housing
this
is
a

2
line
gear.

If
there
is
a
third
port
with
a
steel
plug
or
hydraulic
line
in
the

valve
housing
you
have
a
4
line
gear.

Look
for
the
fourth
port

at
the
opposite
end
of
the
gear
near
the
ID
pad
or
in
the

‘bowl’
of
the
gear
near
the
output
shaft.

It
is
also
helpful
to
know
the
location
of
the
pressure,
return,

and
auxiliary
ports
in
the
process
of
identifying
a
gear.

There

are
four
combinations
of
pressure
and
return
port

configurations.
