a friend picked up this Toro 4 stroke snow blower from the trash. he thought that it was a score, well not so much, lets see if we can figure out what happened to it.
Hey guys how's it going i'm at a friend's house and he was bringing up in conversation about a snow blower that he has out back. That is, i believe, dead on our arrival. He probably could be a better story than i would yeah. I was uh.
I saw it sitting in the trash on the side of the road it looked mint. I backed up grabbed it and threw in the truck before anyone come out. Definitely in a trash pile with a picnic table and an umbrella sure was and uh got it home. Never even tried to start it when i got it home.
I grabbed the rope and it's there's nothing there. This pots missing yeah, so you think it's blowing up, i'm guessing that somebody bought it in a panic, buy from home depot or somewhere with, went home and put the didn't ever put the pine of oil in it that it came with, or maybe the bag of Oil never came with it yeah and she didn't know any better. They didn't know so we're gon na bring it back, possibly try to save it, but uh most likely we're gon na dissect. It probably see what happens so without further ado.
Let's go, throw it in the truck and see what we can do with it all right. Let's see what we got, i don't know if we got a year on it, you see anything about up there. I don't think it's that old. It was it probably within five years old, but it looks like it it's four stroke, so it does not use premix and like they ran it with no premix but nothing same.
They did not run it with oil in it. So i guess you could probably start i'll see if that's possibly the case, at least let's do that. Let's go get a pan that looks like it's water and oil. Where would it fill up with water from through the air cleaner? Let's go get a pan all right, i don't know if that's, oh yeah, a ton of water now was that the aftermath or is that what caused its issues, though i don't know it would have to come in through the air cleaner, would be my guess and Then pass the rings.
Let's, when you pull on it, it seems like it's got. Some kind of here relocate you. You know that's going on the floor. Let's get that out of the way yeah she just free wheels.
Let's go pull the spark plug out. You want to do a spark plug or valve cover, see the valves are going up and down get the plug out of there see the piston's moving generally, if the connecting rod lets go without even turning it well, the spark plug is not smashed shut. That's a good sign. You would basically push down with a screwdriver and you'll feel the piston move.
Don't move, let's go give her a little. The piston is jammed in wherever it is, it's not pushing down. Usually they let go there. It goes and now it'll hit yeah, so the piston let go.
We know it's blown up. Let's go see why that happened. Was it the water that caused it? Who knows, but junk can't hurt it right, curious to see if the valves still move. Tell you if the camshaft got taken out yeah the valves are still moving, one of them that valve's moving that valve's, not oh there, it goes do anything. Is that just floating yeah, it's just floating in there? That's why, with a ton of clearance, i don't know whether the valve, my guess is that part of the valve is bent and that's what all that play is right there. Let's get all the plastics off of this thing, we'll get down to the engine, maybe just rip it right out of there. We'll just do an autopsy see what happened. We got just a bunch of screws.
I may just bring it back after some of the plastic. Is out of the way i got the skins off of it looks like it's hanging from this side, so i see one two three rolling the engine looks like this plate is the only way it touches and then an electric start going up. I think everything else is pretty self-contained. This is the drive system.
Just has a cable that you pull on, pulls this idler pulley down and makes tension on the belt to drive the auger. We're gon na need some more crap out of the way anyway. To take it apart, i'm gon na yank the exhaust off gas tank off, make it a little smaller package. We got to get the cylinder head out of the way, maybe better off working with it.
If we can on this machine. So it's not flopping around a couple: little eights for the gas tank, a little rust coming out of the muffler. Oh, the exhaust port. That's that valve that's screwed too right yeah.
So it was the exhaust one. I don't know if i maybe hydro locked it and it blew up where it went under water. You know it possibly was just some place that was in a flood yeah, because the this is the outlet of the exhaust right there. This is upside down, water would not be able to get up in there.
You know just do the weather coming down on top of it, but i have to fill the if that's how it got in there got in somehow right. Do it's a dollar's worth of? Yes, all right and get rid of this heat shield, we got ta, get the pull start off of it anyway in the carb again, i don't know if it's better to pull it out of there or not. Yet, let's see on this side, those bottom bolts are getting a little hard to get to the head goes. The tin rather goes up over the head, so they get the cylinder head off.
We're going to need this removed i'll pick it away at that, and we got for the carb and that one's gon na be a little hard to get to get this out of our way. It's holding that one screw right there, so so you're coming off! You just don't know it a lot of times. They want you to take the two studs out to get the carb off. You know we're not that concerned.
Let's go look on that intake port, see if you see any signs of egress of water. That looks pretty good. It's definitely on the exhaust side. Did it's like where the water probably got in all right? Let's go see.
If we can get this flywheel cover off, i think we could reach it yeah, let's make it a run for it. Where are you going i'm out of here? I should be free all right. We need to get, i think, the coil out of our way, because it's attached to the head we'll get this tin off of here, there's that now we can see them all. I think we're gon na have to take the rocker assembly off, though, to get the cylinder head out, because we got to get down to that bolt and that bolt. So we got one all these four get them out of there yeah. Even these are bent nope. I come out of there under that valve all right. Let's get those four out ready see.
If we got that that does look bent, it looks stuck. I don't want to wipe everything off yet just for we can use it for exploratory. Look at the top of that piston, though where's our light. Oh yeah, it had a ton of water in it.
You can see where it looks like a valve was hitting right there, like, i said for a long time with the water in it too. I don't know, maybe it was even in a basement around here. You don't, you know we don't get like yards flooding, but the basements do and that may have been the scenario they put it inside the house and then over the corsa. You know in the springtime i've had you know, the sump pump doesn't work and i've had a foot and a half of water in the basement, and that would do it.
I'd fill up that exhaust too. You know all right. I say we go. Let's go spin it over.
I don't think anything's gon na happen. I can see anything. I know that piston is not connected. Let's i think now we can probably remove it from the frame because we got to split the case this way to get to the crankshaft.
So let's get the belt off we'll get those four bolts out. It looks like get it on the bench we'll take that side cover off. I think that's it. There might be another bracket somewhere else holding it, but let's go see two in the back joke there.
Yeah, coming up from here got two more: you will come out of the hole without taking the pulley off, come on down gon na make it difficult for us. Isn't it that's just one bowl these persuasion and i got persuaders now we got it to the vice pop that key out of there stop the covering and those great reveal. Hopefully, everything stays down there with it. I see a bunch of hamburger yeah the rod.
Definitely let loose when i was a kid. There was a game called operation, here's part of the rod and definitely say it spun the bearing bearing overheated and then let go. There's the dipper on the rod that piece that i'm clamped onto that's what splashes the oil up through it, and sometimes they have a hole in them that one did it or not and as it goes through the the hole the hole would be in that piece. Right there, it would pressurize oil into the rod i'll see that on this one looks like the governor's still intact, the hunk of the rod right there.
Um guess i don't know whether the water part of it came after or before. The reason why i'm saying that is because the it didn't seem like it was all that mixed up, then again, it could have settled out over the long period of time that it sat. So i don't know if it was just low on oil. It had oil in it, some oil in it and it almost seems like it would have the correct amount of oil. It doesn't hold much. Sometimes i see where the governor blows apart and that's what i'm poking at right now is the governor. That's that i've seen the governor blow apart and then it over rev and then it take itself out. Let's see if that will stay up there, we'll make it stay up there.
Well, the governor has, as this ring accelerates, it, pushes up on a little cam right. There there - and that is what backs off your thoughts, so it starts over revving. These weights push outward this uh nipple, like a belly words. Actually, that's a pretty good word lifts up and touches on the arm.
I just bent out of the way and that in turn works the governor on the throttle of the car and backs it back off. I've seen them break and then it over rev, and then it just blows itself apart from over revving. That seems like a function. Is pretty good, so i had oil in it doesn't look terribly dirty, neither whether the water came in later or before.
It's probably what i'm questioning. Let's see, i'm gon na pop you in the stand. Let's go get that piston out of there we'll try to drive it with a screwdriver out that way before we do that, let's see if we can lift that camshaft out, if anything's holding it or not there. It goes a little bit more exploration.
I don't see anything burned up on that. It looks like it's got a decompression valve right there, a little tab, that's on there see how it gets in the way of the camshaft lobe and then probably as it spins up that does the same. It pulls away and gets out of the way, that's just for easier starting. It uh bumps the compression down on startup, and now we get to the piston.
Oh, it's gon na break through that rust. For us, though, uh now we got the flywheel stalling, so we can lift the crankshaft out of it. Let me go see. I might go clean up that edge.
Let me go clean. This edge up real quick, see if i can drive the piston through that crap. Take a little scotch brite or something just scrape out it with a screwdriver, see if it even comes off. I think it's gon na fight us a bit, i might go uh grab a honing stone.
I know put a lot of effort into a piece of junk right, wow, good enough, yep, almost crankshaft's. In a way there we go. Let's grab a rag, see if there's any telltale, it doesn't look like the walls were all that bad like it didn't overheat and die some scoring on there, but all the rings still move is the oil ring stuck. I think the oil ring might be a little jammed on that all right, yeah see anything like other than where the piston was parked later.
I think that came later. I think it blew up and then my guess is that the water got introduced later, probably got shoved outside or behind the shed or i don't know it could have rained with no oil. Then they figured uh, it had no oil in it and they added the oil later and it was already too late and then you know once they figured that out. They kind of threw it to the trash. But the fact that the oil and the water were not mixed is why i'm kind of questioning it and then you can see like the exhaust port when we looked where it ran down. Let me look at the case in c2. Yeah it looks like the level was right there, and then it filled up with water to right there. I don't know, i'm not really seeing anything that i can point my finger to that caused it.
It looked like it. It had an oil level like an original oil level, like i said right there and then that, as the water pushed it up, it brought it up to there and my guess: the water came in later governor didn't blow up. The camshaft crankshaft is toast. That is gone, so it bound up on the crankshaft for whatever reason and spun itself to that.
Maybe it's a common problem with them. I don't know both lifters look, okay and it's the only wares there's nothing on the board like it ran hot on the bore. No mouse nests, so that's my guess. You guys are welcome to give yours, i think that's all i have.
I don't see anything else that we can do. If you say that let go, i don't see any damage, no scoring or anything on a cam shaft. All the bearing surfaces, look good huh, hey you see even like crud, that's in there too, like that looks like it happened later on, not now well we're going to steal parts off of it. The electric start is going to be good.
The carburetor i'm going to steal, see that belt that pulley take all that junk. I don't know about the little wheels if i need them for a lawnmower or anything those wingnuts i'll take the springs, maybe the muffler. Definitely the carburetor the pull start i'll steal that coil, a dollar's worth of gas, probably steal that primer bulb. When that ignition shut off for something else and here's the yeah, you would think that it'd be more mixed if it happened like we just don't know how long it sat me, and it would have been good to know that information.
You know if it's, if it's at six months, we say no, this should be milk. If not did you say, oil and water doesn't mix right, maybe a plastic shoot piece carcass i'll get rid of. I don't need anything on that. That's it too bad.
It was a nice machine, you know it was it wasn't a little cheapo. I mean it's as far as no blower goes. No blowers go yeah, it's a it's a small machine, it doesn't uh, it's not very expensive in general. It's probably, i know 359.
Maybe when it was new, it literally hasn't got many hours on it at all. You can tell how the rubber edge on this would get like flapped down to a point: it'll look like a knife edge and that's still flat going right across. So it didn't run very long and let's see how much wear beatness on it cutting edge to see. If the cutting edge looks like it's got a little bit of time on it, not much though yeah could have never put the oil in it to begin with, and it ran for as long as it would run before it spun the rod out all right guys. I think that's it. I think we've done enough damage made enough of a mess. I'm gon na go clean up. I got another project i want to go work on.
I figured something a little different to go chase. Why not work on the snow blower coming in the summer right all right guys with that we're gon na go sign off. Thank you all for hanging out with me and uh tearing some junk apart. We'll do it again, sometime probably sooner than later till then later, and the keep pile, not bad that'd, be a neat piece to do a cold start on.
What's the story behind that uh see it's! It's been sitting so long here that it's almost a new find again for us. We've had it's been i've had it for 30 years, drove it until it wouldn't drive anymore. Then, when my son was in high school, he gave it uh him and the kid next door gave it a rattle, can paint job resto and he drove it to school to show and tell he got an a in that class. That's left that year and then uh it slowly by surely ran slower and slower and slower until the engine didn't have enough compression to run anymore.
So you guys are doing an engine swap on it. Now, yeah we were going to do a rebuild, but it's a type of engine. Is you got to pull the engine to do a valve jaw because the exhaust valves are in the block and the intakes are in the head? So i came across this used engine. That's supposedly a good engine and uh sun's looking for another project, so we run it up to resurrected neat.
It's a 1953 m38a1 i'd like to see this tooling around town. In a couple weeks.
water got in crankcase, turned into a frothy milkshake, and the rod couldn't get proper lubrication. Engine blew and the oil and water seperated again.
I've had a small engine on a tiller fill with water with a muffler like that the the shape let's water seep through the gasket surfaces where the manifold mounts to the head and muffler done the exact same thing with the exhaust valve had to work it back and forth until it had compression and moved freely but mine didn't break a rod it just hydro locked and it wouldn't crank
i remember something about that machine n hear few worker telling other about idiots didnt like machine so he start it up n throw in ponds unite it got hyper lock n broke rod n he return it but they never touch it so it got yeet in piles of trash later other old guy took it lol n now that where you got it n took it aparts now that i remember 3 or 5 years agos
I have the same jeep except mine is one year older
Why not see how much a crank, rod, and complete piston would cost, and rebuild the snowblower?
That Jeep was real nice
Thanks for taking the time to diagnose the failure Mustie1!
Little spackle, fresh coat of paint and it will be just fine
My bets on flooded then someone hooked up the electric start and hydro locked it or something.
My bet is it was started up with no oil, ran a short time and it started getting noisy. It got shut down, they realized it had no oil, they added oil and tried to run it to clear the driveway and got about 20 mins of use out of it, making a racket the whole time, before it went boom boom.
I had a 53 M38 I put a 67 327 Vette motor in it and it could lift the front wheels when you popped the clutch!
That looks like a 196cc honda clone motor. If so, those are pretty big deal in the mini bike and go kart world
New snowblower. Put in gas but no oil, ran it until it started to seize, put oil in it, ran a bit longer till the crankshaft and rod became one, parked it somewhere where it took on water.
Well ya got a few parts for free.
Random guy…. this tiny bottle isn't enough oil…….. top it off with a gallon of water…
I bought a new Briggs engine about 4 years ago it’s running fine but seeing all of these vids with that plastic cam failing I wonder if I have one in that one can’t see why they got that bright idea !
Time for a Harbor Freight 79cc replacement.
