Hello, Garrett here with Partzilla.com,
and today I'm going to teach you how to
do an oil service on a 2005 Honda CRF
450 R. It's a super simple job. Just need
to drain the oil, replace the filter, and
fill it back up. It's that simple. So let
me go grab a couple tools and we get
started.
Okay. Super simple job today so I'm only
gonna rate it as a skill level one. Now
let's go to the tools you'll need for
the job. You'll need an 8 and a 10
millimeter socket, possibly an extension,
a ratchet, and a torque wrench. As far as
the parts go, reference our exploded
diagrams at Partzilla.com. There, it'll
give you an up close and detailed point
of view of how everything comes apart
and more importantly how it all goes
back together. So grab your tools and
let's turn some wrenches. Okay, the first
thing we're going to do is remove our
left engine cover. That way we can
actually remove the oil filter. It's held
in place by one 10 millimeter bolt. Then
we're going to remove the oil fill cap.
That way, it'll allow the crankcase to
breathe properly and actually drain all
our engine oil. Okay, next step is to
remove the drain bolt. It's held in place
with a 10 millimeter bolt as well.
Okay I've got majority of the engine oil
drained out of the dirt bike now, so what
I'm going to do is I'm going to push the
kill switch and turn the engine over
four or five times with the kick starter
that way it will pump any additional oil
out of the engine. Okay now it's time to
install our new drain bolt. But don't
forget to install a new crush washer
before you reinstall it, that way it'll
seal properly. Okay,
now we're going to torque our drain bolt
to twelve foot-pounds. Okay, next up is to
remove the oil filter. It's held in place
with two eight millimeter bolts.
Now if you notice there's two different
lengths of bolts that come out of the
oil filter bracket. The longer one goes
towards the front of the motorcycle, and
the shorter one goes towards the rear of
the motorcycle. Just like that. I'm gonna
take us a flathead screwdriver and pry
the cap off.
And don't forget to retrieve your spring.
That way your old filter will go in
correctly.
If you look at the cap you notice
there's an o-ring there. We're gonna want
to replace it with a new one. And replace
it with our new one.
Okay now it's time for the new oil
filter. Now if you notice, on the front of
it, it actually is marked outside and it
also has a black grommet. You look at the
back side there's no grommet, the front
side there's a grommet and it's labeled
outside. You want to insert the oil
filter with it outside facing out of
course. And don't forget your spring. Now
it's time to install the oil cap. And
starting with our longer bolt towards
the front, and the smaller bolt towards
the rear. Okay, we're gonna torque these
bolts to nine foot pounds. Now we'll put
our engine cover back on.
Okay, the last step now is to fill the
bike back up with oil. Now this model
holds 0.73 quarts, and the oil I'm
putting in it today is Honda HP 4. It's a
synthetic blend. Okay, you may ask yourself, "How often should I do this?"
Well, Honda recommends to replace the
engine oil and filter after every 6
races or 15 hours, so just keep that in
mind. Okay, we have the bike filled up with
oil now it's time to check the level. And
we do that by making sure the bike is
standing straight up. And if you look
towards the bottom of the crankcase you
can see a sight glass, and to the side of
it you can see the letters H and L. Those
indicate high and low. We want our oil
level somewhere between the two of those.
As you can tell, I'll shake the bike back
and forth a little bit,
we're right in that margin. So we're good
to go.
Now it's time to put the oil cap back on.
Well okay, that wraps this one up. Wasn't
that hard was it?
And, it's gonna save you some cash
because you didn't have to drag it to a
pesky dealer. Listen, for parts used in
