Will it run after 80 plus years 1926 Mack model AB truck

Today we have a Mac ab

model

1926

and this old one has been around for at least 80

years

. I'm sure this old one was probably parked at the beginning of WWII and has been in operation almost forever, as you can see on the bumper if you look. Look here on the bumper, you can see where the wires have been routed. I

will

say there was a pulley here and it has a winch on the back so it was probably used to haul things out of a field or It could have been like an Old Wrecker recovery

truck

.

It has this little plaque here on the side. The other one is missing. Mac says and it's in the dog's mouth. He has a book that says the cost of transportation and he's tearing it up, so I guess these. it's supposed to be best for hauling with the engine completely locked, I mean locked, it's a 471 cubic inch engine, let's see here, as you can see, it's a pretty big old four cylinder, that thing is bigger than a d Diesel and her. It makes about 50 or 60 horsepower, so it's not really efficient on a cubic inch to horsepower basis, but it's nice to see.

Missing. I think this was a starter that went here but the fan turns but the engine doesn't say drain and renew the oil. every 500 miles I'm not sure where the oil dipstick is, this may be it. I haven't even checked the oil in this thing, man, that's cool, I just think that's where the earth fools live, uh, yeah, that's all that's down there. The plugs appear to be intact, as you can see, this one here is a plutonium plug, which is why it has that strange color. They started manufacturing them. Well, they use uranium. I think even in the '20s, but it was around 1940, so it was probably working. like 1940 but probably parked around 41 maybe later but it has all the plugs in there they don't look rusty these are old style champions this all looks intact and the ground dobers have plugged it in for us so I mean, that's all. here for the most part, but it's stuck on the inside here, well it's pretty complete, we've got the transmission, it's stuck in neutral luckily because if it was stuck in gear it would cause a world of problems, this is your uh, parking brake and this is something else, maybe another brake, let's say it's another parking brake.

I'm not too sure if this could be a shifter of some kind. We'll have to look at it, we haven't paid much attention to it. I don't know how to check the oil like I said because I don't see a dipstick on this thing under the oil pan. It's oily looking, so that's good, but overall, she's here, the drums. they're locked up like I said and the tires are as old as they can be, let's go ahead and remove the power wash and see what we get, at least the Magneto here hopefully

will

work and we'll remove the hood completely. and clean this out, soak some stuff, fill it with diesel, it'll probably take a good, I don't know, 30 gallons of diesel to fill this, but that will dig up the inside and hopefully it won't be too much.

It's hard to get this old girl to turn and run because I have to say it's one of the nicest vehicles we've ever had to put on the road. Take off these little side caps right here, after loosening or loosening them. just pull that right there and as you can see there's some dirt down there from that nest of dirt, but these are here so you can inspect the rods down there, you can see how big the rods are. We'll put a light here. a minute and this one here just moves and moves and comes out and there are the connecting rods and I mean they look clean, you have a lot of them, you can see the connecting rods here and they're huge, they're 471 cubic inches and the crankshaft is absolutely huge in this thing, everything in there looks good, it's oil down there, it's a weird color because it's probably 100

years

old, it's probably trying to turn back into a dinosaur or something and on this side here you can see there's a a lot of stuff falling down that old dipstick, let's get a rag and clean up whatever we can and well, we're going to wash this thing off with diesel fuel, but first we're going to crawl under it, pull that old drain plug and see .

If there's some oil on it, and after we have it with quite a bit of diesel, that's not really going to do anything to loosen it up, but it will help clean all the gunk out of that pan. Which must happen then. We'll take the plugs out and put in some acetone transmission fluid and maybe some PB Blaster and hopefully in a few days it might take a week but this old one should come loose because it doesn't look like water has run down the rods and that is. Normally, what happens when water or a lot of humidity gets into them, they drain.

You can see a line of rust on the rods and everything there looks nice. Well, it looks like water. Get ready and the moment of truth arrives. Well, that's warm water, oh, well, I didn't need a drain plug, uh, well, I mean a drain pan, and she's completely dry in the oil unless she has a little bit of oh, oh, yeah , has Gunk, is Gunk, oh uhoh, yes, that's what at least an 80 year old has. oil that just set looks like it's basically turned into grease oh there's quite a bit in there oh man good thing we had the big drain pan it turns that weird red color not sure why but that's it thick were those pieces.

There's nothing wrong with performance though, we're going to let this drain over the next probably 24 business days. Looks like in this case we're going to have to go in there and really clean out the bits of the drain hole. probably four or five times this thing has been draining for hours and well, it's still draining. We have one of these neat little battery-powered liquid transfer pumps from Port Fear. We have this thing. We were going to buy one of these just to make. Things are easy but if you bought a 5 gallon gas jug you got one for free so even if it doesn't work like it's supposed to I guess we didn't waste our money because we have a 5 gallon gas jug that we needed .

Let's go ahead and put some diesel in there first. Oh, that thing actually works surprisingly well. A little diesel down there and maybe that will finish our drain. At some point these should be hot enough. I think we're going to hit it. a good spray from the old PB Blaster and yes it looks pretty warm, some of these are almost rusty you can tell and luckily they have that little gap there so you can fill them up and let it sizzle for a minute. Let's move on to the next one, well let's skip this one because it'll set you on fire and we'll move on to these, there's only two plugs on this head and there's four on this one because I guess they plug them in. for some reason, but we'll get them out.

This here seems to be the toughest and hopefully none of these will break. I'm afraid it's going to break. That's a setback. Oh yeah, it probably broke, but at least. We tried it and I cleaned all this so that no garbage falls there. Luckily, let's do our spark plug test here and see if it's hot. We'll do it later. The easiest it can be in these. It's not that useful, there's almost no rust on this one, I mean, one looks new, that's the plutonium plug, and there's quite a bit of stuff on this one, you can see the scary plug well now, maybe I can get to it this way .

So not now, damn it, I just don't want to let go, here we go. I'm going to leave that plug there for a while because it's probably 13 million degrees, unless we can catch it with this, we can, let's see, you can see. You can see there is quite a bit of rust on the end. I mean, it's not terrible, terrible, but now I'm going to show you the inside of the cylinders and it looks like we're going to pull the intake and probably shot it trying to buy back everything we can. We can leave the input on for now and just fill the cylinders and then do it later, it depends on how many things are seen there so that you can see this cylinder here.

Don't look bad, there is some rust, this one has just a little carbon and a little rat. The nest looks just like this one back here, there's quite a bit of surface rust and stuff on that valve. and this one looks clean. I'm going to say this one had an open exhaust valve and it ran fine too, this one didn't and this one didn't because usually the ones with the exhaust valve open look worse when it's an updraft motor. because the exhaust is where things come in and it's a lot harder to get things through the carburetor, then up here and then inside we're going to have to pull the intake, but I'm going to clean this one out and all the other ones look good.

We're going to fill them with PB Blure acetone and anything else we can put in there to help it loosen. Number one is all nice and clean now, so hopefully we can fill it and it won't leak out of the valve. oh I think we're getting somewhere with this one, yeah I didn't have a valve open, these things just slide down these rings real quick because I can already hear it hitting the wool pan and dripping, that one's still empty, it's just Lo The same thing is going to happen with that when it goes by so fast just for fun, let's see if it moves because the rear cylinders have been soaked for a while.

I highly doubt it won't be licked. So as not to hurt anything by doing that, as long as we don't put too much pressure on her, well, all we can do is let her do it and I'll come back to you in a day, two, three, 10, 20 or 30. It depends on how long it will take. this to release her. It usually works within a day or two, but this one seems to be really stuck. There doesn't appear to be any real rust on the cylinders. I think it's just. The surface rusts from its configuration and it heats up and cools and the cylinder sweats, so we let this sit for a week or two and well, the engine is still blocked, so I already removed the spark plug tube, it was just like two wires and we've sprayed this with PB Blaster and everything else, so we're going to take the impact to take the heads off, we're going to take the intake out.

I think it's the valve train that is hanging because these should. No water enters them, but you never know because it is an updraft system. Looks like today will be the day the head bolts completely come out of there, if that's the case that will make our job 10 times easier, isn't that something that one stuck, oh it came out and I know a lot of people like Milwaukee impacts, but I've had this for like 5 years and I leave it in the rain every time it rains and it never gives up. Well, that's the way we got it, although it's also hot, so I think we'll take it out here.

I know someone said you could use plastic shims, they had the idea to not damage the head gasket, but since they are made of asbestos and copper, and the copper is very thin, anything you have that makes direct contact with it and pushing it will bend it, so if you take a saw blade or any flat piece of metal and place it on top of that joint first, it will help. Don't destroy it. I found out that it's not a 100% sexual success rate, but it's about 83.4% and here we go, please don't be Carnage Bo, there's a lot of stuff down there, I figured look at all that nasty stuff, kid.

Oh boy, this thing has some big valves, the dead rubber cylinders, you can put your fist in them and the dead rubber doesn't even touch the sides of the cylinder walls, my goodness, but there's all this crap on top of this cylinder, which is Not good, it was good to get the heads out anyway, but we wanted to get it loose first, but hey, at least we got that one out of there, so we cleaned all that up. I hoped that was what locked the old girl in with all that crap. that was up there, but it wasn't that tight, it was just sitting there from the dirty people that lived there, I'm not sure how they managed to get in there like that because these valves were closed, I guess at one point, this engine when maybe when the guy who got it before the other guy pulled it out of the woods because it was still going because the guy who got it had it for like 20 years I guess and the other guy had it. for over 20 years and maybe when he pulled it out of the woods the engine wasn't stuck and all that stuff was there and it just pushed against there and that could have blocked it but it's still stuck so we're I'm going to take this head off here, it may be a problem with the valve train, as you can see, our ratchet strap is still tight, so it hasn't moved even a little bit yet, but I'll come back to you, let's take this.

Hopefully it will come out pretty easy and we will clean the cylinders, clean the head surface, clean the valves and remove the intake, make sure there is no junk there and here in a while, as long as the Magneto works and As long as we are enough men to spin it, hopefully we'll have it loose and running, okay, it's loose, we're good to go, oh man, here we go, there's not a ton of junk on this and the cylinders are really nice. and nice, you can see there are some things that damaged the head gasket, so we're good there, it must be the valve stuck on this thing, as you can see, these cylinders are really clean,as clean as the others, there is some carbon. buildup, but it should be cleaned right away because ATF and stuff cleans all that out.

This valve is kind of open, it doesn't look like another one is supposed to open or anything, so I'm not really sure what's blocking it and maybe the valve train, maybe something. so it could be stuck lifter but we'll clean this up and then see if we can get it to spin because it still didn't roll after we cleaned that one so I'm not sure what's going on. We will clean the cylinders and buy them. We'll take a wire brush and clean the carbon and lead buildup off of it, but we're going to go ahead and see if we can get this thing moving.

I messed around with the valve territory a little bit down there. little to see but it shouldn't be anything holding it the cylinders are as clean as possible oh I think it's movement I think she's moving there we go oh it's stuck again no I'm just not tough enough it doesn't matter she's moving Come on kid. This thing is hard to get out, isn't it? Oh man, oh, that's why we got stuck in that old cylinder. It's pretty rough, so this one has some rust. Hopefully they can see that they can, but there is a bit of rust and junk on this. and that's what's been holding us back listen to that boy she gets so soft she wants to live oh no, she's stuck again no, no, she's loose again I think something's stuck, maybe one of those valves is getting stuck got stuck, I don't know. everything seems to be open oh yeah, here we go, that's what we want.

She's rolling calmly now, so she got rid of it easier than I thought. It may have been a combination of the things in this cylinder and the rust around here because there's quite a bit of rust and stuff, we'll clean all that out and around this piston and clean the cylinders. It looks like all the valves are working, she turns perfectly, so the next order of business is to clean everything, remove the intake and exhaust and We're going to put some oil in this because it's just diesel and some flooding in the transmission in this moment.

We have to find how much oil is needed. I don't hear the Magneto clicking, so we're going to have to work on that. Old lady, hopefully she hasn't lost her magnetic powers or whatever she's doing there and she turns around, that's the main thing, you can hear the rings, there's a little bit of crap on this and it scrapes, but she turns around smoothly, so that's good. to know that one is gone forever at least we haven't broken anything yet now this should be removed oh boy you can see it's all full of junk the intake valves and stuff is full of stuff that's why we have to throw it away of admission too.

It's broken, the bad boy should come out of there like this, we have to take it off so we can repair it because he has a big old spot where I guess some moisture got in, it just rusted, now we take this out. We're going to have the exact same problem trying to put it back in, so the best thing we can do is move as much as we can and try to get the V input, the input, uh, underneath all of this so that I don't have to. deal with all that, okay, the intake is loose, that's watering the carburetor because I set it on fire earlier, so it's no big deal, now put this here and this here and try to avoid a mess here, boy, that's it heavy, come on. and that's it, go ahead and clean the engine a little more, we also clean the intake.

I thought the broken piece was right there where it is broken. I thought that went to the entrance part, but it doesn't just go around it. I'm not sure how the fluid was leaking from that, but let's make sure there isn't a crack there, but everything on the engine looks very, very good. We've been running it up and down, cycling the pistons to clean the cylinder walls and make sure there's no more junk in there, but I took the cap off that thing with a bolt and it popped off, so let's go check the fuel filter. oil here and see how it looks.

I'm not exactly sure what kind of oil filter they use, but I took it out of there and I'm guessing since it's in the nice warm sun, all the grease will come out and oh, I've never seen an oil filter. so, uh, it's pretty thick, I guess, you know, 80 years, I guess it turns back into crude oil, it's that filter, that's the filter, that's the filter material there and that's rust, so that's the filter, that is grease and filter and grease and filter and grease and filter. and just garbage, uh, we're going to have to get this out of here somehow and it looks like it comes out like this and guys, it's there okay, okay, it might be a two-handed job to get it out, we have to put the camera on.

What the hell is happening here? It just got stuck, yeah, it's very, very well stuck, oh D. Damn, that made a mess, it smells terrible, we have some of that in the cylinders, but we can always buy it back, uh, not sure. If you get a replacement for one of these bad boys, normally we would take the head gasket out and spray both sides, but it's glued to the block and if we remove it, we'll separate the copper pieces and it won't do any good. after that, so this won't have to be a good way to do it, is it there, it's there, just move it and move it and so it's a lot easier than they come off now, a little bit of oil on these . so we can get them to tighten tight, voila, we're going to have to pull the radiator, well, the connector tube to put the radiator hose on, but generally, we put that one in there or all these bolts real quick and start putting it back together, it's time to drain the diesel oil mixture from everything we have in this crankcase so we can clean it the rest of the way.

I'm not sure if this will hold up. every little bit, so we may have to put this drain plug back in, hopefully it will get rid of all those bits. H, it's pretty thick, pretty thick, but we'll have to do this again later because you don't want any of that. in the oil pump and now it's this thing's turn, okay, this is how it's supposed to go and so we have a homemade oil filter. I'm sure they sold replacements in the past to make that thing work, but this thing lasts about 100 years. old and they probably stopped making them 50 60 years ago decided to pour rain today but we're about to put some oil in this thing we had to patch the oil pan with some JB Weld because this is really It's difficult to solder and we didn't want to remove it.

It had a crack, so we made it so the oil wouldn't leak, but everything in there is clean. We're about to put the covers back on. filled with oil, as you can see on the bottom of this dipstick, you see that little one, it's like a spoon, but it's more like a hook that throws oil onto the dipstick, so we have to have enough oil to fill that part. of the tray, so we're about to fill it with some oil and see how much is really needed. Hopefully 5 gallons is enough. Put that old five gallon bucket of oil here and as you can see, it's touching where it should be. a little less here because it's angled that way, but I think these require around 17 or 18, we put it around 20, so it should be more than enough and we're at least one step closer to being up and running again.

The head bolts are now tightened. I tightened them up to 8590 which should be there in the range, one place said 115. I'm not sure how reliable that source was so let's see they are in the 90s, some of them may be a little more and we should be ready to go now let's go ahead and throw these plugs in here and see how hard it is to turn this thing with compression because the more things we put back on it, like the heads and everything it gets harder and harder to turn it, so hopefully We'll be able to turn this by hand pretty easily, no guarantees, although after this we'll have to put the intake and valve train cover on and work on the old Magneto and I think.

Those are the last steps. We'll put a cooling system on it once we get it up and running, but right now we're just focusing on getting it turned on for the first time in 80 years. Well, at least in 80 years it has been said. I guess that's how it is. Time to see if it has compression and hopefully it's not too hard to turn it around. Oh my gosh, it has compression. It has good compression. It's going to be fun to crank this one. I hope it starts well because I don't know if. We have enough ugad duas to start this thing like we did with the old GMC 29 and all the others because it's a lot harder to deliver than you think.

We put the entry here. We cleaned the carburetor and hooked up the fuel line. up although the tank is not connected but we will fill the carburetor with fuel here in a minute the plugs are being tied all this is done on this side the last thing to do is come here and see what this old Magneto does Looks like we have to put it some new spark plug wires and after that as long as the Magneto is working we just need to give it some initial float gas and we should be able to turn it by hand and hopefully it will fire quite a bit.

Easy, you can see that it's a solid piece of aluminum or something here and that's part of the connection points. This is all brass. I mean, it's very well done. They don't even look very corroded when installed, as long as you have this. They look really clean, they need to be cleaned up a little bit and this is the gear that basically drives the distributor error and this just sits here like this and locks it in place more or less and that's what gives you the spark that you need. and that's the time and all that, so I've been working on this for a month of Sundays and we clear all the points and it seems to have a spark, sometimes we're not and sometimes we're not.

I'm not going to show you guys probably the three hours I've been running this thing, but sometimes it sounds like the Magneto is clicking and generating spark, but it still won't reach the wires if you spray it really good. With starting fluid and Spinner, sometimes you will see a little smoke at the points, like they are getting spark, but they just aren't getting spark. If you know what I mean, I'll try to stay out of the way. so maybe you guys can see, I can see, I swear you're getting sparks. I hear it every time now maybe the Magneto just needed to be turned forever, that's every time I'm here, I didn't do it that time, yeah. that time he did it that time he did it that time okay I think they're activating now maybe Magneto is okay I guess he's lost his s magic for 80 years and maybe he just needed a lot of effort 9.4 I think 62 or something so, come on, we crank and crank and crank and crank on this engine and it still won't start.

I think it's getting spark so I went ahead and put in some engine to stop the leak in cylinder number one. I'm going to do that to all cylinders and give it a little star spray and flood before putting the spark plug back in. I can smell gas in the cylinder, especially on this spark plug when I pulled it out so it's getting fuel. just maybe it doesn't have enough compression because the Maring May may still be a little stuck, so the engine leak should give us enough compression to make it work. I'm going to go ahead and do that with the four cylinders and come back. with you and hopefully by then we can have her running, come on, she's going to do it, come on old lady, come on, I'll restore you and make you nice and bright, if you run for me, you've got to run.

Leave Ethan for a while until we break your back, come on man, let's pull it back and see, I've been running this thing for I don't know how many hours counting yesterday and this morning it's like 2:00 now. 1:00 since 8am on and off so I've probably been running it four hours a day or five, I'm not too sure, let's open the choke in case that's our problem, come on girl you caused me a lot of problems today and yesterday and the day before yesterday but still you have to run you have to run that's all I'm going to give you a little more time and if you don't like it I don't know what to tell you we're getting there we're getting there we're getting there shit, come on, come on, that idiot, don't come, come on, come on, come on, come on, old lady, come on, come on, stay running, old lady, oh boy, she's going to run, come on.

Come back, come on, girl, let's try this again, girl, there we go now, woo, she's a runner, it may not have been a good idea to keep them there, but she's running, uh, let's get more gas 'cause We need more gas, she uses gas very well, I guess because of her way as difficult as she was, she seems to run with so much choke and she seems to run, that's all I have to say, this has been the hardest I've ever had . I've once messed with that to get going, like starting it. I thought she was going to die before this started.

Now we're going to get gas, a lot of gas, a lot of gas and a bunch of little spray bottles and us. We'll keep it fed and warm and then let it sit overnight and try to get it going tomorrow. You can see some steam coming out of the top of the engine coolant I guess. I would say radiator hose metal radiator hose, but I'm excited that she's running, she runs, she doesn't like ether at all. I'm defining one here now becausethat thing is extremely loud, we ran it, kept it running for a while. Let's go around, so after 80 something years, we got the old girl running and I have to say she runs great while sitting and it took me like 20 hours of cranking to get her running and I mean, I thought I was never going to get it to work.

This started but finally after I turned it on and it turned red it turned on and works great. Now I put the axle shaft in the back, we were going to try to get it. She was driving for you but we had a problem, the transmission was stuck in neutral luckily when we got her and well she's pretty tough, she's not as tough as the one we have seen above, but the gears are rusted in a way that they will. She doesn't move in any direction and it's pretty rough down there too, so we have to soak it in well.

You can see there's a lot of rust down there. Fortunately, a hole had rusted through the side deck and it remained submerged for probably only 40 minutes. years or so, but the gears are pretty good metal. Let's soak this in some vinegar. It will probably take a couple of weeks of cleaning for everything to come loose and we may have to break it up, but the drums are there. It also got stuck when we went to get this thing. I had to put the

truck

under it because it wouldn't roll. You can see the flat spots there when the guy before the guy pulled it out, he pulled the shaft out because he thought. the back was stuck, but no, it's the drums and they're stuck, but overall we got it working.

It works well. Needs some seals on the water pump. We need to replace that piece there and take out the bolts. because they all broke, but generally the oil pump and everything works, so you guys are going to see this truck again, we're going to restore it, we're going to put new tires on it and you know, once we get it all nice and shiny and on. on the road we could even pull a bulldozer or something, well a small one because that's what it was built to be a workhorse and well it's still not enough to retire on but thanks everyone for watching please consider leaving a I like it or maybe. subscribing because we have a lot more interesting content on the channel and next week we will have a really cool old car and I will see you in the next video.
