Installing a Polaris 180 Pool Cleaner Small Wheel

"ALLYN CHRISTOPHER: We're going to put the bottom of the cleaner on now. Now, this is the original bottom and this one's the new one. Really, it doesn't take a rocket scientist to figure that one out, huh? A lot cleaner and newer. But this, it's more of a benefit than just having a brand-new shiny piece that'll look sharp when it's done. Actually, they're saving you a lot of time by not putting on the swing axle assembly, which can be sold by itself if that's the only thing that fails on you. All right, I've got the old one over here, so we started to back off the screw and the shield, and we're going to take the original wheel off here and--you see, that's a misspeak because there is no way that this is the original wheel. I can actually tell, by the pattern on the outside of it, that this is one of probably many parts that have been replaced on this unit. And also probably because the bearings are in relatively good shape here, all right? Relatively. All right, the swing axle actually allows the small wheel to bob up and down and adjust itself as it transfers power from one wheel to the other. You'll find out, when we reassemble it, that one of the wheels is passive and takes its power, translate it through this, almost like a transfer pulley, and into the space. So that's pretty much over there. No good. Get rid of it. Lotta rub marks at the bottom, lot of 'em. Spending years against the concrete pool, bye-bye. All right, now we got a brand new one over here and now this is a piece that I did not take off just for demonstration purposes, but rather to, you know, it does come disassembled so you have to put it on. Again, though, bearings, preassembled, good benefit. All we're going to do here is just simply slide it on and look at that. Oh, beautiful, beautiful. And then this one over here, again, bearing shield, it's beveled, and this goes in just like a dream. Get a little flathead in there. Don't use the drill on this one; I'd highly recommend against that. And, again, just like everything else on this, not tight at all. Yeah, you don't want to retard any of its beautiful movement. There it is: Brand new swing axle and a small wheel."
