Hello, John Talley here with Partzilla.com.
Today I'm going to show you how to change the front gearcase and the transmission oil
on our 2015 Polaris RZR900S.
Pretty simple to do, let me go grab a couple of tools and I'll show you how to get it done.
Alright guys, this is going to be a skill level one, so it's really going to be easy.
Let's go over the tools you're going to need to pull this off, also a very short list.
As always, a decent ratchet, a couple of different extensions, and an 8mm Allen.
And as always, a good torque wrench.
Alright, if you would, reference our exploded diagrams.
They'll actually show you where the fill and the drain plugs are for the front diff as
well as the transmission.
Alright, as far as the oil, there's two different types, so make sure you get the correct quantity
of each.
So, once you've got your parts and your oil together, I can go over there and show you
how to get it done.
Alright, we're going to start with the front gearcase.
the first thing you need to do is go ahead and pull the full plug, that way it'll actually
drain out.
Now how often should you be doing this?
Well Polaris says every 100 hours or 1000 miles.
And I know that this unit has 102 hours on it at the moment and a little over 1100 miles,
so, I'm curious if they've actually changed this or not.
My instinct says no, so let's see what comes out.
And this is just an 8mm Allen for both the fill plug and the drain.
Alright, that doesn't look too bad.
But it didn't seem like it was that much volume coming out, so I believe she holds right at
8 ounces.
Alright, let's take a peek at our drain plug that actually has a magnet at the end of it.
That's not to bad, that's pretty much normal to see some of the wear accumulate on the
end of this.
We want to make sure that this little O-ring down at the bottom is in good shape.
We've got the magnet cleaned off, so now we just need to reinstall it.
Grab my torque wrench and we're going to take it to 10 foot-pounds.
There it is.
What I'm looking for here is making sure there's no milky discoloration.
If it looks like milk, then it probably has water intrusion.
It could be game over for your front gearcase if it's really milky and it's going to wear
it really quick.
But this one?
It looks good to go, so let's go ahead and get it refilled.
Your fromt gearcase actually uses a different fluid compared to the transmission, and I've
just got a standard Polaris pump and a little bit of hose on the front of it.
We'll just fill it up until it runs over a little bit.
Like I said, it only holds about seven and a half.
maybe eight ounces.
There it is.
It doesn't take much to fill it up.
Take that out.
Let's get the fill plug in there now.
And it actually has the same torque as the drain plug, so 10 foot-pounds.
Alright, next I'm going to go clean out that fluid pump and we're going to go tackle the
transmission, so let's go.
Go ahead and remove the fill plug.
Like the front, it's just an 8mm Allen.
Make sure that you're O-ring is still in good shape.
It is, I think we can reuse that.
And now, let's go ahead and get the transmission drained out.
Alright, don't see much wear on the magnet, so it's looking to be in pretty good shape.
Go ahead and wipe off any fragments that still may be on there.
Like I said, the O-ring looks to be in good shape, so looks like she's pretty much finished
draining, let's go ahead and get the drain bolt back in there.
We're going to take it to 14 foot-pounds.
Alright, I've got the hand pump cleaned out that we used up front, so now we just need
to fill it up.
It's going to take about 40 ounces.
So it's the AGL fluid back here, and the Demand Drive fluid up front, like I said earlier.
So, let's go ahead and start filling her up.
Now when you're doing this you want to make sure the machine's level, otherwise you may
have too much or not enough.
If you're sitting on an incline on your driveway, probably need to compensate for that.
Alright, we've got our second bottle hooked up, let's go ahead and finish filling her
up.
Alright, she's starting to run out so it is full.
Alright, let's get our fill plug back in.
Same torque as the drain, so 14 foot-pounds.
Well alright guys, that pretty much wraps this one up.
Told you it was going to be simple.
