In this video we did a lot of troubleshooting on our Sachs Wankel KM24 Rotary engine swapped ATV frame. Last video we got the engine mounted on the frame as well as the clutch pulleys, so now it's time to get it running properly. The secondary pulley was seized so we un-seized it, but ended up making it stationary due to packaging issues. We made up an exhaust and changed out the bearings in the axle carrier to make it ride nicer. The final result turned out amazing and we're ready to move on to tuning and aesthetics! Thanks for watching and stay tuned for the next one!

So we had a pretty good success with last video. Actually, this thing did move under its own power um. It ran well, and you know, throttle on idle and all that stuff works. So that's pretty great.
What we have to do now is make it you know. Actually drive um, so we we have a rear brake that we're adding. We have to tighten up this belt. We have to rebuild the uh driver and driven pulleys yeah.
There's a lot of work to do to get this thing to actually drive, but by the end of this video. This thing is going to rip, so we're super excited for that. First, we're going to take apart this uh driver clutch pulley and just make sure that everything's, lubed up and nothing's seized or anything the driven clutch pulley is the real problem, though, because, as you can see, it's not fully extended. It's seized where it is right.
Now. Here's the first look: let's see, i'm not exactly sure how this comes apart, so we might have to pull this or something okay. This honestly doesn't look bad uh that roller moves. This one does not so we'll have to clean up some of this stuff, but um.
It's kind of cool you can see exactly how this works. It's pretty simple! So as the engine speeds up, these rollers get forced out and as the centrifugal force increases as rpm increases that forces these out more, which pushes that this in which makes basically from a small sprocket to a big sprocket. So that's how that one works. So all the rollers are cleaned up, none of them are stuck anymore.
We leave them up, everything's working pretty well, there we go so we have this part seized to the shaft it's mounted to, and all we need to do is free that up. So we can pop it off and everything will spring apart, so we're using our hydraulic press. We haven't really used this in a while, hopefully, yeah cool seems like it's moving. Hopefully that's enough, and hopefully, when we release this, everything will come with it.
Oh no just seized more great device, basically just clamped all the pieces of this drive driven, pulley together, so we're kind of stuck. We can't really pull it apart at all, there's nothing to pull on. We can't twist it it's really hard, but we're gon na see. If without the keyway, because we were able to get the key way up that if we just run the engine - and you know it's at max torque right now - so maybe we'll be able to get it to just like free itself or something i don't know.
Nothing can really explode at us since everything's all clamped together, so it shouldn't be dangerous. We'll just have to hope that it comes apart and if it doesn't, i guess we just have more torque and this one doesn't move dude. I don't know how all of our torque is being transferred through that and it's not even been held together, didn't move, but honestly i mean, i think it kind of needs the extra torque i don't know so when we left this thing and went back to school. This was stuck closed um, so we're just going to leave it like that, but i saw jay leno talking about how he restores cars and how he puts parts in a mix of atf and acetone. So we filled up this, go power sports bucket with that mixture, and we let this soak for like a week and i took it out, started hitting with a mallet and it popped out. So i think we're investing that that's pretty cool! This thing was: oh, this one was really seized, there's a bunch of corrosion and rust in there yeah. So i also did some de-rusting too so yeah, all of it kind of worked together to get it unstuck. Okay, oh well! It hasn't moved yet whoa! Okay, you know no crazy explosions, but that is off cool.
Let's see, let's take a look at it, it's definitely rusty, but um. You know at least we'll be able to clean it. Now. Oh dude, that plastic that looks like new.
So when we're doing some test runs on the jack stand, we notice that the axle bearings are pretty shot, as you can see a lot of play there. So we got new bearings and seals here, so we're gon na swap those out. So it's not flopping. All over the place, all right here we go, had to go out and buy the largest wrench we could at home depot, and it actually worked, though so finally, getting this off.
This thing was super tight and had a lot of rust in the threads. So there we go, that is some old grease. It just looks like mud. I finally got these bearings out.
These are cooked, there's a lot of play in them and now it's time to see this little collar thing there we go and let's look at this old grease. Oh my gosh, it literally looks like mud that is horrible, there's profane. Ah that's! This is safe for youtube, so we had these bearings sing in the freezer, so it should go in very easily just a little tap nice a lot easier than taking them out all right. We just pulled this off from the mock-up on the frame and we ended up going to tractor spyko today and got this ford tractor muffler.
Okay, yeah wow wow we're just gon na cut our stock exhaust. We really have no need for this and they're not very valuable, so we're going to use our swag porter band table here we go all right. We just made this little s. Bend it'll be a really easy way for us to just kind of shift the exhaust over a little bit to the left.
Okay, so the exhaust is done. This is definitely the largest exhaust we've ever made for any of our projects. I'll be honest, daniel used to do all of our exhaust welding, so this is my first time ever welding exhaust. I blew through it in a couple places.
It was a little difficult, but by the end you know this weld. I was a lot better, but um yeah. It fits up really well and hopefully we'll be able to fit it in without having to remove the engine, because that would be a pain but we'll see, oh okay, so if our engine is loose, then we can fit our exhaust cool. We got the exhaust complete.
We have a little bit more work to do. We want to position the muffler a little bit better, it's hanging down a little bit too low, but it's really late tonight and i got to go back to college. I got an exam tomorrow, so we're going to you know, start it up, see how our pulleys run and then take it for a drive. Okay, first impressions, it's a lot quieter! That's yeah bearable. It sounds cool yeah, it's still pretty loud, but it's got a deeper. Less kind of buzzy tone to it, foreign, no, it doesn't work. Thank you all for your comments telling us that our driven pulley was on backwards. You know we saw the belt getting all wonky moving different directions in the back, so we definitely have to change that.
We were looking at you know, flipping our driven pulley around into the right direction. The problem with that is that it goes directly into the line where our chain wants to run so then we'd either have to run idler sprockets or a second jack shaft, and we really don't have space for that, especially with like major frame components and the swing On back here in the spring, there's not too much space where we could put that so we're kind of worried that we're going to run into dead ends there. So our decision was to use these lock collars and just lock this pulley fully in fully tight. So basically, our clutch pulley system is now just going to be one clutch pulley that will act like a clutch and then just a pulley in the back.
It'll be a fixed gear ratio, but it'll be a lot simpler, a lot less headaches and you know if we need to change in the future we can. Originally. Our plan was to use these locking collars and just lock it down like that, but we tighten it up and you know this can still spin. So then all our power would just be going and spinning that.
So we need this piece, so we can lock everything together and it has this key way that locks it to. You know the output shaft. The only issue is, you know how to do that since everything's aluminum and our solution is luckily, we bought two of these lock collars. So we'll slide two on and we'll slap this guy down put him in the keyway and you know there is some play which is kind of odd, but you know it's meant to do that.
So you know it'll work. Okay, so that's pretty tight. You know still spins, though, but with our spacers. We have the perfect clearance to add the e-clip eclipse.
We have it, you clip in woodruff key and then it'll stay still, basically, definitely so off camera. We did a little bit of work. The main thing we did was just mounted the pulley back up now that it's fixed and it doesn't expand or contract and uh. When we mounted it back up, we mounted it offset a little bit so when this driven pulley moves to the right, it'll kind of be straight, if that makes sense, another thing we did is replace the old thumb throttle.
It was plastic and it was cracking and it wasn't staying on the handlebars. So we got this one from amazon at the atv. Thumb throttle it's billet aluminum and we'll put an affiliate link. So if you want to check it out, it'll actually help our channel. So now it's time to see if it works, um yeah, oh man, this thing ripped oh yeah. We might need to loosen the belt a little bit but dude night and day like it actually feels hey. What's oh uh all right guys so um we might need to line the belt a little bit more. I feel i smell a little bit of kind of burny smelling or smell, but there also could be.
You know oil in there from rebuilding and stuff um. You know it's not blindingly fast. Obviously this is a 23 horsepower motor, so it's not super fast and it doesn't have a transmission or anything. But i would say the acceleration is comparable to like a fully built mini bike with a pretty q12 or uh, with a torque converter as well or our um, our four tracks.
We have you know it's, it goes um. We might we might adjust the gearing a little bit. You know, make it a little faster, but um. The one thing that i'm not going to do is go fast in this thing right now, because we the front right brake, is the only thing that works right now, so we have to go through all of our brakes before we're going to really rip this thing And you know put it through its paces yeah, but i mean the rear death feels so much more solid, because last time i could feel it shaking around it's just it's.
Actually it actually works. Y'All could probably see i was happy driving this thing. This thing is seems a blast. You know what else would make it faster.
It's a turbo yeah, a turbo huh. I mean that is that is on the table like this video. If you want to see us put a turbo on there, let's just know because that's what we tried. This isn't exactly the best engine because of all that pitting in there.
But you know this thing is awesome. We're really happy with how this has turned out and um. There's a lot more work to do. You know so stay tuned and we're going to make this thing.
Look a lot cooler as well with body panels. You.
I say supercharge it skip the turbo watch the engine really wake up
You guys should really look into fixing a real working cvt, Just a tip, look for something like a powerbloc p50 primary clutch they are good and easy to tune, and a good secondary clutch, at least something that u can tune a little and have it mounted the right way. The acceleration and topspeed would be 10000 times better, with 20-25hp that quad should pop wheelies from the start all day with a good working clutch. however cool build.
Runs and drives pretty damn well! Hell Yeah! TURBO that Rotary engine Guys! It be the perfect test bed for a small turbocharger setup! 👌
Definitely Turbo it
Great job it runs nice and sounds cool.
I'm curious if you can get a Harley transmission geared right for it and use a cog belt primary and dry clutch.
The burning smell is your exhaust melting your gastank 😉
Put another of the same engine, on a Sachs G3 now. 😉
Seems Hella slow
Cool build awesome 👍😎
Turbo!
Helo from Norway🇧🇻
I want to put a turbo rotary in a custom mini bike
Put this against the rotary bike
