Hello, John Talley here with partzilla.com. Today I'm going to walk you through the process
to evaluate-- potentially clean-- and possibly replace the air filter on our 2012 Honda TRX420,
also known as the Honda Rancher. So let's step over to the table, look at the parts
that we're going to need to pull this off, and then we'll dive into it. All right guys
the only part number that you will potentially need is just the part number for the air filter.
Now we're going to look at this one and see if we can reuse it, but with a machine this
old, we really need to be careful and inspect it for any tears or this rubber
starting to break down. Because if this fails and lets dirt and dust get into your engine,
that is a killer right there. And often times it's overlooked.
Now you'll notice, when you open this up out of its packaging, it's actually already pre-oiled.
But I still like to add a little bit more on top of that. I think the primary reason that Honda
pre-oils these as they're packaging them is so that the foam will last longer and be ready to go
in the machine. So let me drop this thing down, show you how to get the seat off,
and then we're going to take a peek to see what kind of shape it's in.
Okay kids, this is really easy, but it's so often overlooked. I mean, as I said before,
if you don't keep this filter clean and dirt, and mud, and dust get past it? You're going to
be doing an engine rebuild-- which by the way we will be doing to this particular unit in a coming
episode, so you may want to subscribe so you'll know when that one drops. I've removed the seat,
it just had one little catch on the back. Now pull these clips back and we can remove the cover.
Let's see what we have in here. Okay, this may explain why we're end-- end up doing a
a rebuild on this engine. Look down here. That's the number one killer for these foam filters
is they get old, they start to deteriorate, and without you even knowing it you've got to split
down here and guess what? That is a straight shot for dirt and dust to go straight into that engine
and destroy your rings, cylinders, valves, you name it. Somebody wasn't paying attention on
this particular unit, and we are where we are. But we're going to show that engine rebuild at
a later date, but for right now, we're going to get that removed and get the new one installed.
It's, it's so simple, but if you don't get in there and at least check it,
this is the kind of thing that can happen. So the only tool you need to remove this is just a number
two Philips. Just loosen up this clamp, rock it a little bit, and then she pulls right out. Hmm...
I think I know why that rip is there, because I see the remnants of a critter invasion.
Pecan holes that have been uh, no, it's a peanut hole that has been um, devoured.
So we had a little furry tenant at one point in time. So before we install the new one,
let's at least get the shop vac over here and uh, and clean that out.
Now you get a better look at that tear. I guess he made a bed out of that.
Well at any rate, we're going to go ahead and swap
that one out. So all you need to do is just get that inner section out.
Now if this one was not torn, the rest of it looks to be in pretty good shape and uh, I can tell
it's like it's only been cleaned twice. See this little mark down here? This little imprint from
that breather that was probably the original and that was probably the second time it was cleaned.
Now could you clean this one up if it weren't ripped? Yes, and PJ1 makes a great cleaner that
I've used so many times, and it really does-- works magic on these things as far as getting
all the dirt and dust and everything out of them. But like I said, this one's got a rip,
so it has to be replaced. There's just no getting around that.
Don't try to tape it or any of that... they're far too inexpensive compared to how much it costs to
rebuild an engine not to go ahead and replace them. So this one is going in the trash can.
Now I'm going to go install the frame. I know some people they'll spray the the foam filter
oil on the inside and the outside. I think that's the appropriate thing to do on like. a K&N filter,
but on a foam one I prefer just to put it on the outside. Personal preference.
All right, now before everything gets really slippery, we'll go ahead and get our clamp on.
Now we're just going to put a light coat on it. Now I can go ahead and warn you, this gets
a little messy. So you want to glove up, I would suggest you go over maybe a newspaper, or a paper
towel, or maybe even the trash can. And you don't have to get real carried away, just a light coat,
that should do it. Go ahead and knead it in.
And now she is ready to go back on the machine.
Kind of have to put it in at an angle a little bit and get that inner frame
inside this boot, and there we go. Then it'll slide up and over like that. Now hold it in place
and tighten down that clamp. Now you don't have to get real carried away on the clamp,
just snug it down. And she's good to go. Next, get our cover back on. You notice it says front, so
pretty obvious it only goes on one way. Just get your clips back on.
Last, get our seat.
All right guys, that is way too easy to do, and really too important to be overlooked. Plus, with
a clean air filter, your machine breathes better and hence it's going to run better, and that way
you're sure that nothing's going to get pulled in and destroy that engine. Well listen, if you need
