【あきらめない！】半死のエンジンを修理する。シリンダーホーニング&バルブのすり合わせ。水陸両用車のレストアamphibious vehicle「MAX Ⅳ」

Oh no, the Kikushin channel is starting. Hello everyone, this is the Kikushin channel. Thank you for always watching. I ‘ve been there. This is the piston that I took apart last time. This side is safe. Unfortunately, the piston ring is on this side.

It was a shame that I lost it, but for the time being, I was able to buy the same standard size piston ring made in 67 on eBay. Well, the items themselves cost 4,000 yen, 4,000 yen, 5,000 yen, etc. I was fine with just the two above, so I

Thought I’d go for something that would fit the bill, this 77m one made in Japan, but it was about 2,000 yen expensive. If it was a 2,000 yen difference, I’d buy a proper one , so I ordered the genuine one.Yes, I’m waiting, so here’s the cylinder.In the meantime

, I’d like to do a little work on Mako’s cylinder.I’ll do it today. I know the work is a little rough here.It’s a little rough here too.I asked a lot of people yesterday and they said it wasn’t good enough for boarding,

So I think I’d like to polish it up a bit.Yeah, it’s okay. Damia, it’s okay, right? It was originally a Noki engine, and it didn’t have that much compression, and it was just the part below it, so it wasn’t the whole thing, so I saw a lot of stuff on YouTube and bought

Something like this, and I was intrigued.It’s called engine cylinder honing. Honing is not boring, it’s a tool used to poke the scratches in the cylinder a little bit so that the oil can circulate better, but since it seems like it can polish things

Up quite a bit, I didn’t push it too hard. There are 120, 180, and 280 that I don’t have , but the first one I bought was this gentle 280, so I thought I’d try polishing it with this.It’s an experiment, so let’s

Do it with this kind of machine. If you stick this inside the cylinder like this and spin it around and around with a drill, the inside of the cylinder will become a little slippery at this part.I’d like to try it out.You can see this scratch

Here. I’m just wondering how far the scratches on the surface can go. I ‘m going to see how far this slightly rough area can be cleaned.Yesterday, I was told to be careful about the accident, so I don’t want to overdo it.The walls are getting too thin

Here. If you do, you’ll have to put in this oversized piston ring, so don’t overdo it.I’ll have to get that piston ring this time, so I ‘ll go with that standard piston ring.Well, you’ll also get an oversized piston ring , but it costs about 20,000 yen. So I’m not saying

That it’s a bit difficult to buy an oversized one, but it’s already quite expensive, so at this stage, I’m going to put this on here, and it’s going to look like this here, and I’m going to use this oil. It’s engine oil. It looks like we’re going to apply this here first.

It’s good. It’s sticky. It’s pretty sticky. Apply a lot of oil to the stone-like engine [music] and let it run . Evenly with the force of the spring. It’s starting to put pressure on me [Music] I don’t know what

To do with this kind of thing, but it’s gotten pretty slippery. It’s already enough. There’s still quite a bit left, but it’s pretty good. Let’s do this too. It’s slimy. It’s slippery and slippery. I’ve put a little bit of it on here.

I’m selling something that can be replaced with just the stone part, so it’s just here. I ‘m still worried about the scratches, but if it’s this clean, it ‘ll probably be fine. You can do that, but I’ll leave it at that for now.It’s pretty clean now

, my hands are dirty, so let’s continue. It’s a valve that opens here and air comes out from here, then it opens tightly and the exhaust escapes from here , but there’s a gap in this and it has to close properly.

Air leaks out of the air.If you do that, the things that come in won’t come in, the things that go out won’t come out, and the things that come in will come out, so this, this , this, kerosene, diesel, this

Here. If you put it in like this, if there is a gap, it will come out. This won’t come out. Yes, I’ll try putting this one in. It won’t come out. It won’t come out. Yes, this is all that comes out. It also came out from the top. In other words, there

Is a little gap here. Okay, here it comes out. I’m going to make it so that the gap here is perfect. The reason why this gap is created is that I ‘m going to do this here and there, but for example, there’s some gap rust around here, so there’s a gap. If

There’s something like that, it feels like it’s leaking from here, so there’s a little gap here and there against the mating surface, so it’s leaking from there. Compression Compression is also not the cause of compression because when you compress the air from here

, it comes out from here, so the cause of compression is this piston.The piston ring was stuck like this.Also, the cylinder had a little scratch like this . Besides that, there was a gap in this valve, so there was a gap in the valve

, so yeah, that’s the cause.It’s coming out from other places as well , but this one is a bit violent.It’s like a monkey.It’s the fastest. Monkey What Patapata Smoky The one that comes up when you watch it on YouTube is the fastest monkey

Patasmo and Makoto is a little bit the cause, so actually it’s like a machine that suppresses this valve like this, so I’m going to press it down, but something is different. I can’t use the valve compressors that are sold all over the place, so it’s a little difficult to use

Because it’s welded here, so I ‘ll just do it as is [Music] Okay, now I’m open. You can see that this gap is a little sagging , or rather, it’s rusty and swollen. I

Think this is probably the case. If I remove it, I’ll just have to squeeze it by biting it too much, but it’s quite difficult to remove it. It’s hard , so I can’t put any force into it. Isn’t there a good angle ? [Music] No , I want to take it off.

Hmm, it’s tough. Probably with this open, the engine stopped and water got in. [Music] Alright, fine . Just sandpaper. I’ve been steadily chipping away at it. Good, oh no. [Music] It’s still a mess. It’s still coming out. It’s pretty good if I take it off. I’ve shaved it off quite a bit. I don’t think it’s perfect, but what do you think? It’s coming from above. Look, look, it’s not

Leaking . It’s not leaking. It’s on. It’s not leaking. Okay, I did my best. I’ll leave it at that for today. It’s snowing again, so I’ll do some work after this. Why do I have to wash my hands ?Next time I’ve taken the trouble to disassemble this part

So I thought it would be okay to rebuild it, so I’m going to try it again.It will take about a month to put the piston ring together. I said it would be from the second half of February to the beginning of March, so it would take about 20 days or 23 weeks,

So during that time, I was doing my best to clean the piston rings. When it comes, I’ll just put it back together and then the engine will start.This time, it’s opened up to this point, so I’m looking forward to it.I hope it’s helpful for everyone.Thank you for watching [Music] know
