Oh, there is some actually kind of deeper pitting and there's also some raised parts, so we're ending up using the same technique that we used on our last rotary, build for the rotary shifter cart. It actually worked great um. We just used super fine grit, sandpaper right now, we're at 400 and we're gon na move step it up to a thousand after we do our first pass, but basically we just glued it with spray adhesive, and we just clamped it down onto this piece of glass. So we have a really flat finish.

This is kind of like a backyard way to do it, but we just want to see if we can get it running and then you know if it's still super bad pitting, then we will have to go to a machine shop. It was kind of interesting to note that there is some scoring on here. You can feel that with your fingernail, i don't know if y'all can see that and then we have this whole area that is pitted so yeah we're just going to lap it and we'll see how it goes so using the sandpaper on this side we went up From 220 grit all the way to 1000 grit, and we actually have some really great results on this. A lot of the pitting is much less pronounced and i do not think we'd really have any problems with compression leaking from this pitting and the score over here is a lot less noticeable and your fingernail does not catch on as much so.

We have really great results for the side housing, so the one problem is the other side. Housing that has the pinion gear is a lot deeper pitted, so we're gon na have to start working on that probably do a lot more pass with the sandpaper and we'll see how that goes so yeah we got the oil seal out and we got the snap Ring out so now per the saks um instruction service manual. We can just uh tap this on a piece of wood. Okay, so now we have the eccentric shaft out.

We can. We can we'll have to decide if we want to get the pinion gear out, but this will make it a lot easier to resurface. All of this all right. So with that, the 1000 grit is done now, honestly, i'm very impressed by how this turned out um visually and just by touch it is extremely smooth, um, even better than the machine surfaces that you know you see on engines and everything um.

You know, of course, there may be variations in like the large scale, but you know small scale very smooth looks great um. This score right here is a lot better and the pitting is not as bad. Obviously, this is not. You know a professionally machined surface, so there could be some problems with this.

The problem that we ran into is we called a couple rotary shops and they really just work on. You know rx7s rx8s and you know large scale, larger and mass-produced motors, and they really don't work on these types of motors. So, to get this machine, we'd have to go kind of like a custom machine shop, um and it'd probably take a long time and be a little bit more expensive than we're. You know willing to spend so we're definitely going to try this first and if it doesn't work, you know, there's still a couple thousands left over there, so they could still um machine it down for us.

It's you know we're not. We haven't ruined the block or anything so yeah, i'm really happy with how this turned out and uh we'll get to assembly all right, so we repacked the bearings with grease. Another thing to note: one reason we might not have had compression is because it seemed like somebody took this apart before us and they use grease to put all the apex seals in we're going to use vaseline, which a lot of rotary guys do and that's because One will lubricate it and keep any like startup, wear and tear from the initial disassembly lube, and also it will burn off, and then the air fuel mix or the fuel oil mixture will then act as a lubricant. Once this burns off so it'll be cleaner and it won't gum everything up, uh nice.

So this is yamabond. It's used for two stroke, casings uh, just as kind of sealant. So, since we're not really sure if these uh casings are warped or if they have any imperfections or anything we're going to use a very small amount of yamabond on the outside side, seal is nice and springy, and now we're doing the corner springs. So these have two springs on each corner, so one face is down and then one goes on top of it and faces upwards, and then we have our corner seal that goes on top.

It springs nicely cool, so yeah before these we're not really springing very much. So this is a big improvement, so we have all the springs working really well and then, since these are split apex seals, we put the small piece in first, so the vaseline will hold that in place. When we put this in there or inside of the rotor housing and then later, we can slip in these a lot easier. So we have our eccentric shaft facing to the right, and then that puts this corner facing right at the spark plug it's kind of nice, because the uh the rotor, only fits in one way.

You know you don't have to like guess or use marks to time or to line everything up right. So all right! So now we get to put the apex seal spring in, do it facing upwards, and then it will go into this little notch on both sides. So the other split side is gon na have a similar notch like this and um so yeah. You just need to get this under that notch on that side and make sure that it's all right and then you can slide the top uh bigger part of the apex seal nice there's our last apex seal.

So with that all of our springs are in. Let's give it a little spin and see what yeah that's cool. Let's see, final installation, it's got a little bit of spring to it, that's good and now the bolts. Okay.

So now we're talking these two six foot-pounds, which is not very much but it's aluminum casing. So now see this bad boy's got compression, that's definitely harder to turn yeah. I honestly dude. I think we actually have a really good chance of this.

Somehow working yeah yeah yeah. No, that's like genuine compression. I mean, of course i have no leverage right here, but that's better than it was before it was kind of spin over with nothing so high hopes. This actually may have some compression.

I think it's at least gon na have enough compression to run. You know it. May not be a you know, peak power, but i think we got a good chance now that the magneto assembly is on, which is also pretty cool, because this also has a generator for lights and for a battery. So we could run a headlight on this thing, which would be kind of cool but um, so now we're putting on the fan.

One interesting thing is the threads on. This are really messed up, but they're not just like bent or anything they're chipped off. So it seems like the previous owner hammered on them problem is that we can't get this nut to thread on, so we have to put this castle nut on backwards, so it skips those first couple of threads, it's kind of weird and not ideal, but i think It's better than having that little oil pump or fuel pump sticking out of the front of the engine. The last piece to go is the pole cover, so i'm actually super excited for this um.

We spent a lot of time working on this. A lot of work into it - and you know it'd, be great to save some money, and i have to take this thing to a machine shop now if it works good enough, it works good enough. We're not trying to our original plan was actually to turbo this engine, but um after seeing the insides of this. That is definitely not even an option.

I would not trust this thing turbocharged. So there's actually one piece that i forgot to put on here. We need the counterweight for the accenture shaft on this side. You know i was just checking they are paying attention, so we'll put this on it's about time to test yes, sir, so yeah i checked for spark.

Everything seems to be doing. Well, you just give it a couple of pumps. Oh that's! That's very satisfying yeah. It was a lot of work but yeah.

Okay, so we'll put the carb on and we're trying to actually run it all right, get up fuel all right, um, yeah carb is not tuned, so we're just gon na. I guess we can start by trying to do it without or should we just? We might just start with starter food: all right go for it, heck yeah, look at the uh. We got a lot of smoke, smoking up, baby smoking it up what that dude no way yeah. I guess we've got to get an exhaust and everything built up, but that's all the proof we need.

I mean that was no starter, fluid just had it on the throttle and then i actually kind of idled as well. So that's pretty insane um. It looks like we got ta work in rotary, so wow, let's go. That was great.

That's probably one of the best case scenarios for this thing and i think we can keep going with the build start it up like a champ sounded like it ran pretty healthy. Just bits of flames too, it was pretty sweet. So next up it's trying to get this thing fitted on to our atv frame. It's going to be a little challenging because with the clutch pulleys and everything it's a pretty big assembly but um, i don't think it should be too difficult and then we'll be one step closer to having probably one of the world's only rotary atvs.
