A
Welcome
hydroxyl,
101,
so
global
village
construction
set
relies
pretty
much
completely
on
hydraulic
power
as
a
way
to
transfer
power.
So
we
use
power
cubes,
which
are
modular
engine
units
and
using
hydraulics
power,
cubes
and
hydraulic
components.
We
can
modularize
design
completely
because
power
is
transferred
through
hoses.
So
starting
with
a
power
cube,
we've
got
an
engine
which
is
right
now
a
standard
gasoline
engine.
The
engine
is
connected
to
a
hydraulic
pump
through
a
direct
coupler
you're.
A
Transferring
the
rotary
motion
of
the
engine
to
rotary
motion
in
a
pump,
which
is
basically
a
pump
that
pumps
fluid
at
very
high
pressure
and
that's
how
all
the
power
is
transferred.
The
good
thing
about
it
is
that
so
you
have
this
big
engine
and
then
a
tiny
pump.
It's
literally
like
this
big
and
this
little
little
thing
carries
like
right.
Now
we
have
the
27
horsepower
power.
Cubes.
This
little
thing
carries,
creates
the
fluid
at
very
high
pressure
like
2,000,
to
3,000
psi
that
transfers
the
power
to
all
the
different
wheels.
A
This
bypasses
the
need
for
transmission
because
the
transmission
is
done
through
hydraulics
and
these
hoses
are
flexible.
So
you
can,
you
can
attach
any
kind
of
active
power
component
very
flexibly
instead
of
using
things
like
transmissions
and
mechanical
shafts.
So
essentially
a
hose.
You
know
like
a
half
inch
hose,
can
transfer
50
horsepower
of
power.
Then
you
go
to
a
three-quarter
inch.
Hose
I
can
transfer
like
hundred
hundred
horsepower.
So
very
tiny,
conduits
transfer
a
lot
of
power
and
it's
a
very
effective
way
that
allows
us
to
now
go
into
absolute
modular
design,
its
plug-and-play.
A
We
use
quick
couplers
where
the
fluid
hoses
and
all
the
components
are
connected
by
quick
couplers
that
just
basically
snap
in
and
snap
out,
so
we
can,
you
can
plug
and
play
like
a
life-size
Lego
set.
So
there
are
five
main
components
pretty
much
when
we
talk
about
hydraulics
and
the
main
concept
is
continuity
of
fluid.
If
you're
pumping
this
fluid,
it
has
to
like
a
circuit,
it's
a
circuit,
it
flows
from
one
outlet
of
pump
and
then
it
returns
on
the
other
side.
A
But
it's
a
complete
closed
circuit
and
when
you
design
anything
here,
that's
one
thing
to
kind
of
think
about.
You
always
have
to
keep
the
continuity
of
fluid
going
and
it's
kind
of
a
basic
design
principle.
So
how
do
you
do
that?
The
main
components
are
valves,
cylinders,
motors
and
then
there's
two
more,
which
is
a
flow
control
valve
and
a
cushion
valve
and
with
those
five
basic
five
elements
plus
fittings,
we
can
power
all
the
things
that
we're
talking
about
right
now
in
the
six
and
sixty
campaign.
A
So
what
is
about
that
there's
two
main
types
of
valves:
it
basically
allows
fluid
to
flow
in
one
direction
or
another
direction.
So
this
example
right
here
is
a
bi-directional
flow
control
valve
push
it
one
way:
fluid
goes
out
one
one
outlet
and
goes
back
the
other.
You
push
it
the
other
way.
It
goes
out
the
other
outlet
and
goes
back
in
the
other
and
the
way
you
feed
these
is
so
the
hoses.
A
Basically,
if
you
have
a
power
cube,
then
the
hoses
that
go
into
it
going
on
one
side
and
come
out
the
other
so
to
draw
that
you've
got
your,
so
you
start
with
your
power
cube
that
has
two
outlets,
so
we've
got
two
outlets
for
the
power
cube.
You
go
to
your
valve.
Your
flow
control
valve
basically,
fluid
goes
in
to
one
side,
then
goes
out
the
other
side,
and
you
complete
the
cycle
like
that.
A
So
you
can
connect
to
anything
you
want
to
this,
so
this
will
have
the
two
outlets
in
and
out,
and
you
can
control,
for
example,
a
cylinder,
so
so
one
side
of
the
cylinder
one
in
the
other
inlet
of
the
cylinder
and
goes
in
and
out
so
you
can
control
it
both
ways
if
you
connect
it
to
a
motor
instead,
if
you
don't
have
that,
but
instead
you
connect
it
to
a
motor.
So
basically
the
motor
will
have
two
two
outlets:
we've
got
some
motor
with
a
shaft
going
one
side
go
out
the
other.
A
If
you,
if
you
have,
if
you
go,
you
can
basically
reverse
the
direction
of
the
motor,
so
you
can
go
forward
and
backwards
per
cylinder.
That
means
extraction
extension
and
retraction,
and
you
can
you
that
Valve
allows
you
to
go
in
one
direction,
one
direction
and
say
like
that:
if
you
press
the
valve
stake
up
and
then,
if
you
reverse
it,
then
then
you
go
back
this
way
and
forward
that
way,
so
in
control
the
directions,
it's
it's
pretty
easy.
A
Now,
there's
two
types
of
valves:
that's
the
main
thing
like
when
we
design
this
two
types
of
outs:
one
is
a
cylinder
valve
and
there's
a
unique
valve
for
a
motor.
You
can't
actually
control
you
can
use
the
same
valve
for
both,
but
here's
what
happens
so
a
Sun.
What's
what
does
it
cylinder
valve
mean?
It
means
that
once
you
when
you,
when
you
push
it,
it
will
stay
there.
It
doesn't
let
fluid
freewheel
after
you
push
it
to
a
certain
position.
A
That
means,
when
you
extend
the
cylinder
it
will
stay,
there
will
be
very
firm
staying
there.
If
you
used
a
motor
valve
to
be
able
to
push
that
rod
back
in
and
out,
because
the
fluid
can
actually
flow
freely
and
that's
the
difference,
the
the
freewheeling
action
that
I
described
is
very
useful
for
a
motor,
because,
if
you're
going
forward,
if
you
lock,
if
you
release
the
valve
and
just
stop
it,
it
would
come
to
a
dead
halt
and
you'd
screech
to
a
halt.
A
So
so
that
that's
why
you
want
to
use
a
motor
valve
for
things
like
tractor
or
truck.
You
want
to
use
a
motor
valve,
because
that
means
it
will
keep
freewheeling
whenever
you
release
it,
which
is
which
is
good,
and
if
you
want
to
stop,
you
can
actually
pull
it.
The
other
way
and
you'll
be
able
to
stop
that.
You
bet
basically
reverse
the
direction
to
make
it
actively
stop.
A
Now
that
might
sound
like.
If
you
push
it
one
way,
then
you
reverse.
It's
like
well
something's
gonna
give
well
that's
right,
something
is
going
to
give,
and
that
is
the
the
valves
typically
have
a
pressure
relief.
So
there's
a
there's
going
to
be
this
kind
of
a
knob
on
the
side
of
a
valve
and
you
adjust
it
to
set
it
from
low
to
high,
like
three
thousand
will
be
maximum.
A
Typically,
if
you
set
it
to
low
setting,
then
when
you
do
something
like
reverse
on
up
on
a
vehicle
it'll
like
bypass
the
fluid,
while
still
stopping
so
it
won't
jerk
it
jerk
you
around,
but
be
smooth
and
allow
you
to
stop
so
the
other
component
that
I
mentioned
was
a
flow
control
valve.
If
you
look
at
that,
so
that
valve
so
instead
of
this
have
a
flow
control
valve.
A
A
When
you
push
the
lever
all
the
way.
One
way,
all
the
fluid
will
go
out
of
this
one
say
exit
one,
and
if
you
push
it
all
the
way,
the
other
way,
all
the
fluid
will
go
up
exit
two.
So,
for
example,
if
you
connect
this
to
the
different
sides
of
a
micro
track,
you
can,
in
the
middle
you'll,
get
have
50/50
so
you'll
be
going
forward.
A
You
go
all
the
way
to
the
to
the
one
side,
only
that
one
side
will
be
going
forward
and
the
other
one
will
be
just
there
steady
and
if
you
do
it
the
other
way,
then
so,
if
you
have
to
say
that
you've
got
that,
like
the
micro
track
with
two
wheels,
not
in
the
full,
like
the
full
to
the
left
position.
Only
this
will
we've
gone
so
basically
you'd
be
able
to
turn
around
like
this.
A
So
that's
that's
what
it
would
do
this
we
can
use
either
this
or
just
just
two
of
these
valves
for
the
micro
track.
If
you
use
this
one
that
wheel
right,
there
is
not
locked,
so
it
can
go
forward
a
little
bit
because,
let's
see
we'll
have
to
see
it
in
practice,
but
we
can
experiment
using
one
of
these
valves
or
just
two
of
these
for
each
side,
because
if
you
use
this
one,
then
you
actually
have
a
reverse
on
each
side,
which
is
which
means
that
you'll
be
able
to
like
spin
in
place.
A
You
won't
be
able
to
spin
in
place
with
this
kind
of
valve
for
simplicity.
We
don't
need
to
do
this
right
now.
So,
let's,
let's
work
with
just
these
simple
ones
and
maybe
like
scratch,
doesn't
that's
just
for
your
reference,
but
let's
scratch
this
one
for
now,
because
we
can
definitely
take
two
over
these,
so
you've
got
so
now
you
have
a
double
no
two
spool
valve
you'd
have
once
again
you've
got
in
and
then
out
come
and
coming
back,
and
then
you
have.
This
has
got
to
to
help
us
here.
A
So
this
would
be
to
one
wheel,
motor,
and
this
would
be
to
the
other
wheel.
Motor
this
other
side
would
be
to
the
other
wheel,
motor
on
your
tractor
on
your
micro
track.
So
you
can
go.
You
can
literally
spin
in
place.
So
that's
how
you'd
wire
that
up
so
getting
to
the
cylinders,
it's
things
like
loader
arms,
that's
where
this
other!
Third,
let's
call
the
third
component,
the
the
cushion
valve
is
important.
What
that
allows
you
to
do
is
when
you
have
a
cylinder
control
valve.
A
If
you
raise
so
you're,
lowering
lowering
a
heavy
loader
filled
with
stuff
on
things,
if
you,
if
you
lower
it
and
then
just
stop,
it
will
just
totally
come
to
an
abrupt
stop.
So
that's
where
you,
you
use
the
cushion
valve
that
we
showed
in
fact
the
hydraulics
101
page,
because
that
will
basically
make
it
go
like
it's
going
down
fast
and
then
just
kind
of
slows
and
and
stops
otherwise
you'd
be
like
getting
bumped
up
every
time.
You
move
the
loader
down
it'll
like
lift
it
back
up
kind
of.
Do
that
thing.
A
So
now,
I'll
just
describe
briefly
what
the
things
are
that
you're
looking
for
like
some
of
the
because,
because
in
surplus
center
anywhere
that
you
look,
there's
gonna
be
hundreds
of
types
of
these
valves
and
so
I
want
to
just
tell
you
what
are
the
main
things
you
need
to
look
for
critical
thing
about
these.
It
has
to
be
open
center.
A
What
does
that
mean?
That
means
open
center
means
that
that
fluid
goes
right
through
it
through
the
center
and
flows
out
when
it's
not
activated,
because
our
hydraulic
power
cube,
always
pumps,
fluid,
there's
other
types
of
pumps
that
are
called
like
variable
displacement
pumps
where
you
know
which,
which
they
either
pump
fluid
or
not.
So
they
it's
a
different
mechanism
that
you
can
actually
control.
A
How
much
fluid
they're
pumping
here
we've
just
got
one
volume
of
fluid,
which
is
for
a
27
horsepower
power
cube
it's
about
14
gallons
per
minute
for
the
new
50
horsepower
power
cube,
it's
gonna
be
about
28
or
25
to
28,
something
like
that.
So
for
the
large
power
cubes
that
we
use,
we
need
to
have
30
gallon
per
minute
valves
if
we
use
the
small
power
cube,
there's
20
gallon
firm.
That
involves
us
more
than
enough
for
the
14
gallons
per
minute
that
we
have.
A
A
That's
basically
the
same
as
hot
as
pipe
fittings
in
your
house,
but
it's
easy
to
work
with
and
as
opposed
to
the
there's.
Another
type
called
sae,
which
has
got
ol
rings.
Some
of
it
will,
whenever
we
can,
let's
not
use
The
Awl
rings,
because
the
the
NPT
is
kind
of
like
more
flexible,
it's
easier
to
it.
It's
kind
of
easier
to
work
with
in
some
way.
A
In
a
sense,
that's
easy
to
design
the
circuit
that
way,
because
if
you
have
any
time
you
have
you're
going
from
NPT
to
SAE,
you
need
to
have
adaption
so
because,
for
example,
the
quick
couplers
that
we
use
are
all
NPT.
We
would
always
need
an
adapter
so
so
to
use
to
reduce
it
down
to
all.
Npt
really
works
for
us,
because
that
way
we
use
a
finite
number
of
fittings.
Otherwise,
like
the
number
and
different
types
would
just
get
it
out
of
control.
There's
there's
also
British
pipe
thread.
A
There's
the
o-ring
one
and
then
there's
the
NPT.
So,
let's,
wherever
possible,
use
NPT
unless
you
have
to
because
it
simply
doesn't
exist.
I
can
tell
you
that,
on
the
huge
wheel
motors
that
we
use,
those
are
British
pipe
thread
for
some
reason.
So
we
just
have
to
go
through
that,
meaning
that
we
get
an
adapter
from
surplus
centre
at.
A
B
A
And
then
you
just
put
so
this
is
a
female
fitting.
Typically
I
have
female
fittings.
That's
that's
a
standard
email,
it's
standard
on
these
valves.
So
here
what
that
means
is
you
need
an
empty
team
mail.
A
hose.
Does
that?
Well,
ok,
but
here's
the
trick
so
so
far
free.
So
one
OC
open,
Center,
two
NPT
three
was
the
GPM
value
either
like
20
or
30.
There
they
typically
have
you'll,
see
it,
but
there's
30
gallon
per
minute
ones
will
need
those
for
the
big
power
cube.
A
Why
we're
also
doing
MPT
is
that
you
can
actually
go
to
the
store
and
get
one
from
the
plumbing
store.
There
they're
a
little
different
there
they're
weaker
at
the
store
they're,
not
as
strong,
but
they
work
for
return
lines,
but
for
pressure
lines
it's
not
a
journey,
a
good
idea
to
get
to
use
this
once
from
from
the
plumbing
store,
because
they
they
will
break
they're
like
there.
We
have
some
of
them
on
an
old
tractor
and
they
haven't
broken
yet,
but
they
can.
We
definitely
do
track.
A
Sometimes
the
dedicated
by
drunk
ones
that
you
get
its
surplus
center.
They
look
like
hacks,
they're,
more
hexagonal
like,
for
example,
the.
When
you
look
at
the,
for
example,
the
nip
it's
gonna,
be
kind
of
like
X
agonal,
and
then
you
got
the
threaded
part
of
here.
That's
the
hole
there
thread
it
apart,
they're
the
ones
for
the
store,
look
like
the
ones
that
are
hydraulic,
they're,
just
like
straight.
They
just
got
thread
here
right
there
and
you
need
like
a
pipe
wrench
or
clamps
to
call
them
to
tighten
them
here.
A
You
have
this
hex
to
tighten
it
down.
Next
part.
Here
is
the
quick
couplers.
We
want
to
make
all
of
our
components
quick
couple
such
that
if
we're
prototyping
these
machines,
so
you
can
take
one
valve
we're
done
with
with
prototyping
the
the
micro
track
can
put
the
valve
on
a
different
device
like
the
iron
worker.
So
we
don't
have
to
build
up
another
one,
because
you
got
to
put
in
all
these
fittings.
A
A
B
A
Looks
like
that,
it's
quick
coupled
this
one.
It
has
this
kind
of
a
spring
spring-loaded
ball
that
once
you
take
off
the
coupler,
it
doesn't
leak
fluid.
So
you
can
have
one
of
these
devices
just
sitting
there.
You
take
off
the
hoses
and
there
it's
sitting
there
ready
for
use
without
leaking
fluid.
So
here's
two
parts
here,
so
this
quick
coupler
nip
valve,
nip
quick
coupler
and
then
on
these
fittings.
At
best
we
have
once
again
like
1/2
inch,
NPT,
so
another
nip,
but
in
another
net
all
typically,
all
these
are
female.
A
So
there's
another
net
coming
out
here
and
then
put
a
quick
coupler
on
that.
The
convention
we
like
to
use
is
male
for
forgiving,
like
meaning
like
forward
flow,
would
be
like.
If
you
have
a
outlet
that
would
be
a
male
male
outlet,
the
female
would
be
the
receiver.
So
that's
the
convention.
We
want
to
want
to
do
for
the
valve,
since
they
both
give
and
receive
they're,
both
like
since
it's
double
acting
they're,
both
in
and
out.
Let's
just
set
a
convention
of
like
make
the
bottom
one
st.
A
like
wherever
the
valve
is
just
make
that
we
have
to
set
some
convention
so
they're
all
the
same.
Let's
just
set
the
convention
that
the
bottom
is
say
female
and
the
top
is
male,
quick,
coupler
male,
quick,
coupler,
female,
quick
coupler,
so
so
the
female.
That
means
you
have
this
one
here
and
this
one
that
looks
like
that
here.
A
A
A
So,
but
this
once
you
identify
the
30
or
20
gallon
version,
there's
only
like
one
type
of
out
just
select
one,
if
there's
many
different
ones
like
different
brands,
just
go
through
one,
the
prince,
what
we
did
today,
we
use
the
Prince
brand
of
valve
that
pretty
much
covers
the
bi-directional
valve
and
these
valves
can
be
single
double
spool
triple
to.
However
many
you
want
for
like,
for
example,
for
the
cab.
You
want
them
to
be
individual
on
a
micro
track,
it's
probably
easier
to
have
one.
A
That's
got
two
directions
and
it
depends
on
what
device
you're
working
on
you
can
select
single
double,
so
I
mean
another
specification
is
like
one
or
two
three
valve
like,
for
example,
on
the
backhoe.
We
want
to
have
one.
That's
like
that's
things,
got
like
six
cylinders
to
control
motors
motors
next
and
you
have
any.
A
This
make
sense
so
for
motors
it's
the
same
kind
of
be
able
to
perfectly
you've
got
a
motor.
It's
got
an
outlet,
you
know,
got
an
outlet
in
the
simplest
fashion,
II
a
motor
will
so
here
we
had
eight
a
minimum
of
eight
components
that
come
to
make
enough
a
valve.
So
for
a
single
valve
for
motor
you're,
gonna
need
like
say
it's
got.
Sailor
motors
got
once
again
look
for
NPT.
A
B
A
A
its
lubricating
outlet,
that's
not
at
pressure.
It
kind
of
lets
fluid
bypass
within
the
center
of
the
motor
so
but
there's
another
quarter
inch.
These
are
typically
like
half-inch
fittings.
There's
a
little
quarter
inch
one,
that's
that's
there!
So,
since
that's
the
one
that
really
dead,
that
bypasses
fluid,
which
convention
should
we
make
it
first?
Which
convention
should
we
make
make
these
ones?
Let's
say
that
if
we're
looking
at
the
shaft
of
the
motor,
let's
just
do
this
here.
A
This
is
gonna,
be
left,
is
gonna,
be
male
rights,
gonna
be
right,
it's
gonna
be
female.
Let's
just
do
that.
This
we
gotta
just
select
something
so
that
it's
uniform
everywhere.
Now.
What
do
we
select
for
the
gender
of
the
out
the
outlet?
What
is
that
going
to
be
done
by
our
convention?
Is
it
male
or
female?
Most.
A
Good
because
it's
it's
an
emitting,
it's
not
receiving
it's,
it's
giving
fluid,
so
it's
cold
as
male,
so
that
this
will
be
a
male,
quick,
coupler.
So
a
quarter-inch,
it's
a
quarter,
inch
male
coupler,
now,
quick
coupler
and
typically
all
these
ones.
The
quick
couplers
there's
actually
two
types
of
most
of
them
that
we'll
use
are
going
to
be
12.
So
all
the
outlets
from
the
valves
we
can
do
twelve
out
like,
for
example,
if
we're
running
cylinders
do
twelve.
So
that's
that's
another
height
of
here
four
cylinders.
A
Do
the
they're
do
the
small
ones
which,
with
the
12
GPM
gallon
per
minute,
half-inch
quick,
couplers,
the
inlets
and
outlets?
Typically,
you
want
to
make
them
larger,
because
that's
we
can
stack
these
valves
up.
We
can
put
like
the
next
about
next
to
it.
So
let's
make
these
three-quarter
fittings
whenever
we
and
well
on
a
micro
track,
you
don't
need
3/4,
so
we
just
have
to
make
decisions
like
you.
Definitely
don't
need
3/4
on
a
micro
track
and
in
the
price
difference
like
the
the
half-inch
couplers
are
about
15
bucks.
A
The
the
30
on
permanent
couple
of
quick
couplers
are
30
bucks
about
so
there's
a
little
price
difference,
but
if
we're
using
the
good
thing
actually
about
the
the
fittings,
though
the
quick
coupler
is
that
both
of
them,
the
30
and
15,
can
plug
into
each
other.
So
you
can
interchange
them
for
the
motors
hydraulic
motors,
what
I'll
say
is
half
inch
ones
for
the
small,
the
small,
more
small
applications
like
the
micro
track,
but
we
really
need
to
go
to
3/4.
If
you
talk
about
the
bulldozer,
you're,
definitely
3/4.
A
If
like,
for
example,
if
you've
got
four
wheels
and
fit
and
say
30
gallons
per
minute,
if
we
have
a
50
horsepower
power
cube
right
now,
the
30
gallons
divided
by
4
is
only
8,
so
actually
the
small
ones
would
do
for
now.
But
if
we
have
more
power
in
the
future,
we're
gonna
need
more
from.
In
the
meantime,
we
can
actually
just
do
one
half
I
can
do
one
half
for
now,
since.
A
B
A
Then
there's
simple,
simple
gear
motors,
so
there's
various
types
and
the
amount
of
torque
they
give
out
depends
on
all
kind
of
mechanism.
They
have
inside
they're
quite
quite
intricate
when
we're
going
to
do
to
build
these
because
we're
going
to
build
these
in
the
future,
we're
going
to
start
with
simple
gear
type,
pumps
and
motors,
and
at
that
point
we'll
be
able
to
make
a
huge
hydraulic
motor
and
we
will
not
need
our
gear
down
that
we're
building
right
now.
But
right
now
those
huge
hydraulic
motors
are
gonna,
be
like
five
thousand
dollars
each.
A
A
Now
the
cushion
valve-
let's
talk
a
little
bit
about
the
cushion
valve
if
you've
got
so.
If
you're
designing,
like
the
real
real
case
of
cylinders
on
the
backhoe,
you
got
say:
individual
cylinders
on
the
on
the
loader
you've
got
one
valve
acting
on
two
cylinders,
so
you're
you're
gonna
save
got
the
valve
you
going
to
to
the
two
cylinders
you
go
out,
then
you
have
to
tee
it
out.
A
A
Consider
consider
the
t's
teeing
out.
That's
all
it
really
is
for
the
loader
arms,
for
example.
Now
for
the
loader
arms
we
we
need
to
put
in
the
cushion
valve
in
this
with
in
this
circuit.
So
where
do
we
put
it
so
now
for
that?
Let's
talk
about
the
cushion
valve,
so
it's
like
a
square
square.
Looking
thing,
it's
got
basically
two
inlets
on
one
side
and
two
outlets.
A
A
The
fluid
goes
like
that,
typically,
under
that
shot
condition
what
it
will
allow
is
there's
a
spring
inside
there,
and
it
will
allow
fluid
to
cycle
like
that,
so
it
can
continue
falling
down
a
little
without
getting
locked
right
there.
That's
basically
how
it
works
to
to
put
it
into.
How
do
we
put
it
into
this
circuit
here
we
got
to
put
it
between
the
cylinders
of
the
valve.
A
Well,
just
put
it
in
like
right
there.
So
basically,
these
two
outlets
here
and
there
that's
what
you
need
to
do.
You
can
look
at
the
existing
life
track
to
see
where
them
to
identify
those
those
cushion
valves
and
basically
kind
of
replicate.
What's
going
on
there
and
concept
is
here
like
when
you
do
the
select
your
components.
A
You
have
to
look
at
the
geometry
like
where
you
are:
where
is
the
valve
pointing
to
how
is
it
oriented
so
you
might
need
to
have
elbows
like
instead
of
this
snip
here
you
might
need
a
nip
elbow
because
they'll
be
like
real
geometrical
considerations
at
all
times.
Otherwise
you
get
this.
This
crow's
nest
of
hoses
everywhere,
which
is
presently
the
status
of
the
existing
tractor.
A
We
like
to
do
it
right.
That's
why,
when
we're
moving
to
the
cab,
we'll
try
to
organize
it,
so
it's
really
well
organized
and,
and
the
only
like,
for
example,
for
the
cab
you
just
have
a
plug
in
into
the
cab
and
then
an
exit
and
then
a
case
drain.
And
then
everything
is
like
all.
The
levers
are
inside
and
there's
outlets
for
the
arms
for
the
motors
from
that
from
that
cab.
But
basically
we
try
to
organize
it
as
well
as
we
can.
We
want
to
eventually
go
to
metal
tubing.
A
I,
don't
know
if
we're
gonna
have
time
right
now,
like
metal
tubing
that
you
just
plug
into
that
and
they're
fixed.
So
you
don't
have
to
worry
about
the
hoses
rubbing,
because,
basically,
what
happens?
If
the
hoses
rub
any
time
you
activate
them,
they
kind
of
stiffen
up
and
I
kind
of
punch.
So
so,
if
they're
up
against
each
other,
there
they're
going
break
very
quickly,
if
you
don't
have
them
properly
aligned
and
arranged.
A
So
that
is
I
mean
we
go
through
a
lot
of
hoses
here,
because
we
haven't
really
fixed
that
issue
of
mounting
them
in
a
proper
way.
That's
perhaps
one
of
the
big
challenges
of
doing
this
is
that
you
have
to
mount.
It
have
to
actually
put
a
lot
of
attention
to
how
you
how
you're
gonna
mount
it
yeah
and
then
eventually
go
to
the
metal
to
me
now.
A
We
cover
all
those,
let's
see
the
five
components,
so
we've
done
cylinders
motors
you've
got
the
valve.
We've
got
the
cushion
valve
and
we're
gonna
forget
about
the
fifth
component,
which
is
the
flow
control
valve
which,
which
controls
the
amount
of
fluid
to
each
exit.
We'll
forget
about
it.
So
that's
that's.
Basically
it
I
think.
That's
you
know
for
the
this
little
instruction
on
hydraulics
101,
that's
that's
about
it!
For
now,
any
any
questions
or
okay!
That's
it
cut.
