Hi, I'm Eric from Rocky Mountain ATV/MC.com
And today I'm going to show you how to change the oil on a modern Honda four stroke.
The supplies we'll need are rags, an oil drain pan, some common hand tools, oil filters.
Today we're going to be using the Billy Who Man Funnel. A service manual and some quality oil.
Rocky Mountain sells a wide variety of oil and oil filters.
CRF's have two oil compartments, one is the transmission, the other is the engine oil.
We're going to start first with the transmission oil. We're going to take off the cap.
We're gonna loosen the drain bolt.
The we're going to get our Billy Who Man Funnel and line it up underneath the bolt.
Then we're going to go ahead and remove the bolt the rest the way and let the oil out.
This funnel is necessary if you have a skid plate, but it also helps just making sure it's not as messy, even if you don't.
Now that the oil is drained, we're going to remove the funnel and reinstall the drain bolt.
We're going to torque this to 16 foot-pounds is what this service manual calls for.
To fill the oil we're going to take out our oil level check bolt first.
And then we're going to go ahead and refer to our service manual.
Get the approximate volume that we need to put in it. And then we're going to watch our oil level check bolt.
As we add oil, we'll notice the oil start to flow out. That's when we know we have enough.
We'll go ahead and reinstall the oil level check bolt.
Go ahead put the cap back on.
And then we're going to move on to the engine oil.
And the engine, we're going to go ahead and remove the cap.
Sit it aside
Now we're going to drain the engine oil. The drain bolt is actually located underneath the engine.
Go ahead and let the engine oil drain completely.
And then we're going to reinstall our drain bolt
We're going to torque that to approximately 18 foot-pounds. Always check your manual to double check that.
And then we're going to change the oil filter and to do that we're going to go over on the other side of the bike.
There's the oil filter cover. Go ahead and remove that.
And when you remove it, there's a spring on CRF models that you want to make sure you don't lose.
And also take note of how the filter was mounted onto the cover.
Go ahead and replace it with the high-quality oil filter like a Tusk Oil Filter.
A little bit of oil on the sealing surfaces makes it so we don't tear anything when we install it.
Put the spring on. If that spring won't stay there, a little bit of grease in that recess will hold the spring during installation.
Slide it in, make sure everything fits in nicely.
And then reinstall your bolts.
Check your owners manual for torque specs.
Now it's time to add the engine oil.
And once again the Billy Who Man Funnel makes it a no mess oil fill.
We've checked our owners manual so we know approximately how much oil to put into it.
But you still need to check it with the dipstick or on the four wheeler models there is also a sight window.
So what we're going to do is we're going to go ahead and run the bike for a few minutes.
Now that we've ran the bike we're going to check the oil level.
And you un-thread the dipstick. Clean it off.
And then sit it back in the hole without threading it in.
And this is how you get your correct oil level.
The Tusk Oil Filter comes with a maintenance sticker to help keep track of your oil changes.
Once you apply that, then you're done
