Hi my name's John Talley and I'm with Partzilla.com.
Today we're going to be working with our 2007 Honda TRX400EX and what we're going to show
you today is how to do a simple oil change.
This particular unit has what they call a dry sump system meaning that you have oil
inside the crankcase as well as the oil tank.
To get things started, we just need to crank it up, let it idle for about two to three
minutes, get everything circulating through the system then I'll walk you through the
process of how to get it drained and refilled.
Alright?
Let's go!
And welcome back, I've shut off the machine and now I'm going to show you what tools we
need to accomplish this task.This is a really short list, only three sockets are necessary.
We need an 8mm to pull the oil filter cover, we need a 12mm to drain the crankcase oil,
and then a 14mm to drain the oil out of the oil tank.
Alright, first things first, we need to get the oil out of this machine.
Like I said, we need to get it out of the crankcase and the oil tank as well.
First thing we want to do is at least loosen up the dipstick on the oil tank itself.
Next, we want to go to the 12mm on the crankcase and go ahead and take it off.
We want to be careful not to drop the crush washer and get it lost, otherwise that would
make it leak.
Next, while that's draining, we want to go ahead and pull the drain bolt off the oil
tank itself.
Same scenario, as the crankcase drain bolt, it has a crush washer which we do not want
to lose.
As this is draining completely I'm going to take you to the other side of the machine,
go ahead and pull the oil filter, and show you how to replace it.
Alright, let's go ahead and get that oil filter out of there.
This way you only need that 8mm socket.
There's only two bolts holding it on.
What you're going to see on the other side of this cover is the oil filter itself and
a spring on the other side of it.
Don't be alarmed if a little bit of oil dribbles out when you pull the case.
Warned ya!
There's our oil filter.
And then tucked up inside there is our spring.
Basically you just want to leave it up on the case.
Alright, here comes the tricky part where you need to take note.
You can actually install this oil filter backwards and that would be catastrophic for the engine.
But fortunately for us, printed right on the side it says OUTSIDE TOWARDS FILTER COVER.
That's what we want, facing toward the outside of the engine.
We make sure our spring is still up in there, lay in our filter, and then get our cover
on.
You can only put it back on one way because these two bolt holes are offset, that will
tell you naturally which way it should go.
While you're up on the case reinstall your 8mm bolts.
This is a fairly small thread so there's no sense getting carried away on your torque.
Get those tightened back down, about right there.
And we're done with that.
With that finished all we need to do now is put back our drain plugs.
First, let's do the drain tank.
That's the 14mm, you want to get it in there started hand tight no sense getting carried
away on this but they want about 12-13 pounds which my internal torque wrench says is right
there.
Next we go to the 12mm and do the crankcase.
And roughly about the same amount of torque is needed for it.
About right there.
Alright, with that finished, all we need to do now is refill it.
Before we actually pour the oil into the machine we'll look at a couple different lines of
oils that Honda makes.
First is the tried and true GM4 oil, this is your generic oil that you see in 90% of
your vehicles, typically your work vehicles.
Second, you go with an HP4M, now this is an ultra-high performance oil typically only
used in race conditions.
Typically because it will get absorbed into the wet clutch plates and make them slip so
you better be ready to change those if you want to run this oil.
Now the oil I prefer is the HP4, this is without poly but is a synthetic blend that is designed
to put up with extra heat and stress on a high performance engine.
Now with our oil filter replaced, and both of our drain plugs in place, it's time to
go ahead and refill.
Now the trick with this machine is that it has a 1.9-quart capacity and the problem is
we can't pour all of that in on the first go.
So what we need to do is go ahead and put 1 quart in, run it for about 10-15 seconds
and then add about three-quarters of the second quart and then check it.
Let's go ahead and get the dip stick out and get our first quart in.
We can go ahead and fill it without fear of it overflowing.
Alright, she's in.
Go ahead and pop your dipstick back in.
What we're going to do it start it up and let it idle for about 10 or 15 seconds.
What it's doing now is essentially pulling the oil out of the oil tank into the engine,
filling the voids where the oil filter is.
That should be enough.
Now what we want to do is pop the dipstick back out, let's go ahead and grab our second
quart.
I wouldn't dump the whole thing in there because like I said it holds 1.9 and the last thing
you want to do is have to drain out some of your oil.
So go ahead and add about three-quarters of it and what we're going to do is start it
back up and let it run a good bit longer, probably around 1-2 minutes, shut it off,
and let it sit for 2 minutes and then check the levels.
So we're going to start her up and we'll be back in a few minutes.
OK, so now she's set for a couple minutes let's take a look to see where we really are.
Alright, to check it, we just pop the dipstick back in, don't screw it in, just pull it out,
and we are about at the halfway point.
Which is good enough, but I prefer it to be a little more toward the upper level.
So let's add just a tick more.
Don't get carried away.
Just to bring it up on the mark just a little bit more.
That's what I want.
About three-quarters of the way up.
Put your dipstick back in, snug down, no sense in getting carried away.
And once I take the oil to the recycler, we can call this done.
If you have any other questions, or if you need any of the products, come see us on Partzilla.com
and we'll get you taken care of.
Thanks for watching and have a great day.
