Today we're going to replace a camshaft in a Polaris 500. I'm going to show you what to do, what to look for. I've got all the plastic stuff already. All you're going to need for this job after you've got everything removed is an 8mm socket and an 10mm socket. First, I'm going to make sure you're at top dead center. You look down at as the mark line up the flywheel for the top mark and that'll put you at top that center. What I like to do is take the recoil cover off so that way I can line everything up. Make sure I am at top dead center. So I took my recoil cover off, put a mark on the flywheel, line everything back up, get everything at top dead center. I took my access cover off and took the bolts off for the rocker cover. So the dawn at hole is a little mark here and is a mark on the flywheel. Well that ought to mark that. I am at top dead center. Take that cover off, this is a rocker cover off. See what kind of damage I have here. I have a plan with this. I learned that if you take a H.O. cam and an H.O. carburetor, you can make this a Plairist 500 H.O. So that's my plan. So I'm going to show you how I plan to do it. So here we go. There are also two marks up here on the gear. Those have to be straight up and you know you are at top dead center. Next up is a cam off. We are going to go to the other side of the machine here. We are going to go for a ride. Alright. So you got your elbow for your top coolant holes and then there is an access cover for the cam down here. So I am going to pull that out. So I am going to start cam with it. And that access cover. So you have to go on here. There is one, two, three, four. I will take those bolts off. This will come right out. It will be a little slight to cam off. Last bolt. Yeah that doesn't look bad at all. There is not a whole lot of wear. There is one little groove right here. So I am guessing that cam is good. So what I am going to do is take those three bolts off. Make sure my mark is up there and then I am going to take a piece of wire and hang that up out of the way and then I can pull the cam off. And last thing I forgot, before I do that, right there. That is the chain tensioner. Comes out with two eight millimeter bolts. And you need to get that off first, otherwise this chain is going to be really tight. Just stop down there pretty good. There we go. It looks like there is a little push button right here. Push this down. When you install this, you take this bolt out. There is a spring in there. Leave that out. Push this down. It stays in. And then you will reinstall it. Put the bolt in with the spring in and it will put tension on that chain. I am going to show you my little trick here. Move back over here. I don't want to have the chain come off the gear or some tension on this one. I am taking this bolt out. The idea is to hang this up out of the way. I have everything to stay intact while I pull the camera. That is all. Now, when I pull the camera from the other side, I don't have to worry about losing my position on the gears or the timing marks or anything. I will set over to the other side. I will give you a shot of what I have got going on here. I don't have much wear on that cam. That should be sitting pretty good. I can take that access cover off over here. That is going to be stubborn to this bolt. There it is. There is a little oarring in there too. It keeps it sealed. Now, I should just build the side that came right out. Be careful because this cam is still good. I will try to see it. It can look good yet. I can reuse it my next project. Now, when you want to install your new cam, just do the reverse of what I said. There is one last step. It is 0.006. I posted a video on how to adjust that. There you have it. It is pretty simple. Thanks for watching. Subscribe to my channel for more player's fixes.
