Hello, John Talley here with partzilla.com.
Today we're going to be doing an oil change and checking our the air filter on our 2011
Polaris Sportsman 850.
Polaris is kind enough to send you an oil change kit, and what it has in there are two
quarts of oil and the correct oil filter for this application.
We're also going to take a look at the air filter and see if it needs to be replaced.
So to get started we need to crank it up and let it idle for about two or three minutes
just to get the oil system circulated and heated up.
So, I'm going to go ahead and start her up, let it idle for a while, and then we'll get
into it.
Alright, we've got her heated up so we can go ahead and start the process.
Let me show you a couple of tools you're going to need to accomplish this.
The drain bolt is just a 6mm Allen head, so nothing that specific.
What you will need is a oil filter wrench.
so if you don't have one of these you'll need to pick one up because it's almost impossible
to get to without it.
Alright, it's going to be a little bit difficult for you to see under here, but your drain
bolt is right here.
It's that center hole.
While that's draining, we can go ahead and pull the oil filter off as well.
Go ahead and get your drain plug back in place.
Make sure you've got your crush washer on.
Before you put it on, go ahead and put a little bit of oil on that outer seal.
Get it snugged down.
Right there.
Alright, we've got our oil filter in place, the oil drain plug is back in and snugged
down.
Next, we need to just put in two quarts of the Polaris oil.
And you actually fill it where the dipstick is.
It's a nice big opening so you can actually do this without a funnel.
There's one.
In goes number two.
Go ahead and pop your dipstick back in, and we're going to start it up, let it run for
a few seconds, then check the level.
Alright, we've got our drain plug and our oil filter back in place.
We've run it for a couple of minutes, it's settled, so let's check the oil level and
make sure we're okay.
To do that, Polaris actually wants you to screw it in all the way.
First you have to bring it out, wipe it off, so you can get a good reading on it.
Pop it back in, screw it all the way back in.
And that's what we want.
we're right there in the middle so that's dead on.
Alright, next I'm going to go ahead and drop the lift down, we're going to pull the seat
and we're going to take a look at that air filter.
so give me a minute and we'll get this thing dropped down and we'll go from there.
Alright, well we've got our oil and our oil filter changed, so let's take a look at that
air filter.
Alright you need no special tools to do this.
Just grab the back of the seat and pull up on it really hard and it'll release.
Next, go ahead and remove this little air vent end and the end of the airbox you've
just got these two through bolts that hold on the outer cover.
Like that, pull it up out of the way.
Now what we're going to see in here is the air filter and the pre-filter.
What the pre-filter is is basically just a shower cap if you will for the air filter
itself.
Alright, it doesn't look super dirty.
We want to go ahead and pull off the pre-filter and see what the actual filter looks like.
Alright now that's looking a little rough.
You can tell this one has gotten wet because it is actually moldy.
I can't imagine that that's letting it breathe very well at all.
So we're going to go ahead and replace this.
So, let me run to the stockroom, pick up the correct one, and we'll get it popped in there.
Alright, I went and got another air filter, so we've got that ready to go because I definitely
don't want to reuse that.
The other thing we need to do is go ahead and clean this pre-filter, and all you need
is like soapy water to do that.
So let's go ahead and get her in there and get some of this crud off of it.
Looks like it's coming clean a little bit.
Once we get all of this scraped off we want to let it be completely dry before we put
it back on the air filter itself because as you can imagine paper and water don't get
along very well.
Alright, not exactly perfect but it's better than when we started.
What I'm going to do now is just get some regular water to get the soap off of it and
then I'm going to let it air dry.
Once it's through drying, then we can get it put back on the air filter and get it popped
back in there.
Alright, so, we'll be back in a few.
Alright, we've got our pre-filter cleaned up and dried off.
Mine has a couple of holes in it, so it's getting really close to needing to be replaced
but I'm going to go ahead and run with it.
If your has any large rips in it we want to go ahead and replace it.
Alright, all we need to do is just slide it back over out main filter-- preferably without
ripping it.
That'll do.
Now what we need to do is on the end, the one that's the intake is take a little bit
of grease and seal up that edge like that.
Back in she goes.
Be sure it's seated all the way at the front.
Get on our rear cover.
Just get these two bolts just hand tight.
Get your little rubber boot into that vent.
Then just pop our seat back on.
And with that, that completes our project today.
Well listen, if you have any questions, just leave me a comment below and I'll do my best
to answer.
