This is Eddie here with Messick's service.
Today we've got a BX
that that has transmission issues.
We're going to let you peek inside,
take a look at what happens inside a transmission.
This video is
by no means instructional,
it's just to give you a
point of view and take a peek
inside a transmission
and let you see what's going on inside.
As you can see, we've already got
the transmission up on a stand.
We've gone ahead,
we pulled the hydrostatic pump
and motor out,
pull the top cover off the transmission.
We're going to go down and
stand up here and let you guys look down inside.
As you can see, we've got
the transmission top cover off
standing up looking down inside.
Main input shaft,
this is what's going to transfer the power
from the engine into the transmission.
Four wheel drive
which we have in neutral right now,
so rear PTO,
front PTO.
On your input shaft,
these gears right here,
this is where your pump would ride.
Spinning this shaft,
this shaft next to it your main PTO shaft
is where your motor would be
spinning the PTO.
We've now taken and stuck
the rotating group
of the hydraulic pump
and motor,
set them down on the shaft so you can see.
As this pump goes around,
it goes over what we call a swash plate
which has an angle on it.
It's curved.
As this pump turns over this,
it causes these pumps
to actually pump.
These pistons move in and down the pump.
The swash plate on how this angle is
set is controlled by a lever that comes out
through here.
On this unit as you push the lever forward,
it will cause it to go one direction;
as you push the lever backwards,
it'll cause it to go another direction
causing you to go forward
or reverse.
This pumping action from this pump
is what creates the pressure
to make this motor spin.
This motor uses that pressure
in order to cause it to spin,
and depending upon
whether you're going forward or reverse
would depend upon
if your motor went forward and reverse.
We'll make this go around,
this is in
low range right now.
We'll then move the--
Let range selector down,
engage the other gear,
this will put us in high range.
Much easier for me to turn,
tractor will go much faster.
Now we have four-wheel drive,
this is in neutral right now,
we can shift that
into four-wheel drive.
At that point when we spin our axles,
four-wheel drive shaft would spin
so your front wheels would also
engage for traction.
On this side of the transmission is
where the PTO takes place.
Front PTO,
all of our gears are spinning;
rear PTO,
I can spin this but you can't see anything,
the clutches and everything are all down inside
this would be spinning this
makes your rear PTO spin
when it's engaged to your front PTO which
spin off of this shaft.
Now, we're going to pull out a handful
of these gears
and allow you to look down inside
and see what happens below this level.
We've gone and pulled out all those
gears on the top,
we're now looking down in at the differential.
You can see as we turn the shaft,
the differential goes around.
We're now going to lock in the diff lock.
You can see that diff lock move.
Basically, that just makes the becks lock up,
they cannot turn independent,
they turn together now.
Here we have the four-wheel drive shaft,
slides in and out,
bearings on this shaft made in Japan.
The gear
slides on the shaft.
If you were to look at the gear on the edges
you'll see
normal wear marks
from this being shifted into four-wheel drive.
All of those little particles that wear off
are picked up by your filter,
that's why it's important to change you filter
on a scheduled basis.
Hope you enjoyed our
teardown of this transmission.
