[00:00:10]All right, guys. Welcome back to the channel. I'm Baz and this is another chapter of welder the fabric. Now, let's go and see what's just turned up.

[00:00:29]lot that's the doors are in LN contractors that we looked at in the last video. It has actually come early because it dropped a track.

[00:00:41]So rather than messing around, we thought we get it done, get it boxed off pretty quick.

[00:00:48]So, I got Luke coming in today.

[00:00:53]See who's left on this one.

[00:00:56]As I have done me backing over the weekend and I mean I'm in absolute agony here. So, I'm going to try and find a chiropractor today. Um, probably getting old playing with kids on trampolines.

[00:01:15]just what I didn't need at this moment in time. So, I got Luke and Ian on this job. They should be able to uh box that.

[00:01:22]Although, I wanted to be on it.

[00:01:43]So, it's dropped a link on the drive there.

[00:01:51]I'm just wondering if the seal's a blown track tensioner.

[00:01:59]So, like I said, it did drop a track.

[00:02:01]So, it must have been this track. That's why it hasn't been washed off. They couldn't track it to the power washers.

[00:02:06]They basically just put the track back on and parked it up.

[00:02:12]And we've no power wash, so it'll be a case of uh getting the needle gun on where all the bolts are.

[00:02:23]Yeah, that could be a problem on the idler end.

[00:02:31]See where to get it stripped down.

[00:02:34]We'll just gas these chains off. Gas them off. Get it out of the way. We need the daughter off the deck first though, so we might make a frame to put under the back end.

[00:03:14]So, we dropping a link there. I'd say the uh that seal's definitely blown in that side. Now, then past experience tells me if you do one side, do the other side. So, we'll reseal both sides.

[00:03:26]But what we'll do, we'll split it apart.

[00:03:29]have a look at the piston, make sure the piston's all good. If the piston's damaged, then it might be a case of a new piston as well, but we won't know till we get it apart. So, basically, tracks off. We'll look at the slack adjuster, and then we'll get that away for a reseal, unless we can get the seals and do it ourselves. All depends on the piston.

[00:04:04]Oh, turn that way.

[00:04:18]Heat up here.

[00:04:56]Heat.

[00:04:59]Heat.

[00:05:18]Heat.

[00:05:35]Heat. Heat.

[00:05:50]Heat.

[00:06:25]Heat. Heat.

[00:06:47]Heat. Heat.

[00:06:51]Heat. Heat.

[00:07:37]Heat. Heat.

[00:07:54]Heat.

[00:08:05]Heat.

[00:08:25]I thought that would have come out very easy, but obviously not. So, I've just put a chain around the blade.

[00:08:43]Yeah. So what happened there was the guide had slipped out and wedged. So now it should come out easy. Just get a bar on it. Lit bar out. That I say I knew they should have come out easy.

[00:09:01]A chain and a strap down.

[00:09:21]Heat. Heat.

[00:09:28]Heat.

[00:09:52]Heat.

[00:09:55]Heat. Heat.

[00:10:26]Heat up here.

[00:10:40]Heat.

[00:10:53]Heat.

[00:11:19]So, the holes in the drives aren't as bad as we thought.

[00:11:23]I reckon they're good enough to go again. So, we've gunned them up.

[00:11:26]Obviously, we got two men on a bar tightening them up. Got the top rollers on.

[00:11:34]We noticed some of the were bars are too far gone.

[00:11:39]You've got little were bars here. The piece missing there. This side's completely missing. Just a little bit on back end there. So, we're going to have to dig that off. And the side ones. Can you see how that's all worn down? So, we'll cut some plates on plasma. Cut them off. Weld some new ones on before we put the advers back in. We want to lift the back end up now. So, there's no point using Jack when we've got the uh UK's number one record in our yard, is there?

[00:12:16]That's good thing about being in this shed.

[00:12:19]We can use that whenever we want.

[00:12:28]Now for those people that might not have seen this before, this is the only one at UK it's sliding back on. Is it >> only one slides, one roll?

[00:12:36]>> One slide, one rolls.

[00:12:38]So this crane will slide back. How far does it go? About 6 m. 6 mish. So we'll get it bang on it middle of dozer and we'll just pick the dozer up. I reckon we should get a drone up director.

[00:12:54]Heat. Heat.

[00:13:26]So, we're just coming up with a rigging plan now.

[00:13:29]And we're going to use two tens on straps around the drives at the back.

[00:13:33]And we got this big loop going through the eye at the front.

[00:13:39]So, it shouldn't shouldn't be allowed to go anywhere. Very safe.

[00:13:45]Heat.

[00:14:04]Heat.

[00:14:09]Heat. Heat.

[00:14:30]Heat up here.

[00:15:10]Heat up here.

[00:15:41]Go a try. Yeah. Just see if there's any movement.

[00:15:45]Come on. Just take a bit of weight. Keep an eye on it. See if it moves in a bit.

[00:15:58]Well, I think you put a bit of wood behind it some.

[00:16:20]>> He's going down. He's going down here on frame.

[00:16:29]Yeah.

[00:16:38]>> Straighten that up a bit.

[00:16:41]Want to straighten that up a bit.

[00:16:43]>> Slow it down. Slow it down.

[00:16:50]>> That's it.

[00:17:05]So we just put some timber in there really just so we don't put any weight on that ram going now.

[00:17:20]Spin it.

[00:17:23]Spin it.

[00:18:13]Take the metal. And then you want to go in with your front one. I'd say a little bit. So you want blue in a slight bit.

[00:18:26]Bit more blue.

[00:18:28]>> Watch out.

[00:18:48]It tell you the weight on there or not?

[00:18:50]>> Yeah.

[00:18:50]>> How much?

[00:18:52]>> 15.

[00:19:01]>> 15 ton.

[00:19:05]Are >> you putting these under it?

[00:19:22]>> Yeah.

[00:19:24]>> They're going to hold it.

[00:19:26]>> Too far out.

[00:19:30]>> It's creaking a bit. H it sure knows the blade drops over there.

[00:19:57]Probably better going real it. Is it long enough? No. I'm going have to put one on. Let's put one on each side of it.

[00:20:03]>> Well, it's not going to go much, Blair, is it? Pull it right pull it right through that.

[00:20:20]>> Check it up that we'll put it out drive.

[00:20:22]Take it up a bit more at back.

[00:20:24]>> Luke, drag another trestle out from shot.

[00:20:29]Thank you.

[00:20:30]>> Just here.

[00:20:34]>> Yeah, but you're better off having more as well.

[00:20:43]>> Yeah. Not too far cuz it goes better anyway.

[00:20:49]>> Yeah. Better better leg. Yeah. Do you want that other one? Uh, >> stop it sliding. Yeah. You got this small bit.

[00:20:56]>> Nah.

[00:21:00]>> What are you thinking, Luke?

[00:21:04]>> That'll allow us to get to all this. All right. As well.

[00:21:06]>> Yeah, we only need to get that that >> cut them off. Yeah.

[00:21:12]We want We want that as close to that as possible, don't we?

[00:21:28]Yeah.

[00:21:44]>> Yeah. We're good at this.

[00:21:49]Hello.

[00:22:03]Heat.

[00:22:10]Heat. Heat.

[00:23:02]So now we got it landed on some trestles.

[00:23:04]We've kept 30% of the weight on the straps, although we could take it off if we want, but we're only changing the bottom rollers. And we're only doing it for a little bit of character to the video for you guys, just to show a little bit of this million pound recorder. And just basically what we can do in the yard being good pals with the owner, proper thing.

[00:23:28]As long as we don't send any sparks towards it, which we won't need to. We can do that when it's on the deck as we change these were bars.

[00:23:36]At this moment in time, we're just going to needle gum all the nuts and bolts or just bolts. Take all the guards off, all the bottom rollers, replace everything, drop it down. Really, I could do it for lifting this side though.

[00:23:49]Fort lifting this side to lift the bottom rollers up. So, might take all the weight off it just yet. We'll see.

[00:23:57]Heat up here.

[00:24:33]Heat up here.

[00:24:50]Heat.

[00:25:12]Heat.

[00:25:16]Heat.

[00:25:30]Heat.

[00:25:38]Heat up here.

[00:26:13]Got it.

[00:26:15]>> So, I just got a new set of seals. Might as well do both sides now. Then, why this was passing grease and they couldn't pump this track up was because of that. That's the important bit there.

[00:26:27]That white one.

[00:26:30]Yeah. And you see how it's missing off there.

[00:26:34]So that allows it for grease to pass so that idler wouldn't be able to push out when you're putting grease into the grease valve onto that.

[00:26:46]So we'll strip these apart. We'll clean these rods up. These rods are a little bit scarred, but we'll clean them up with a little bit of emey cloth and uh they'll go again no problem. So now we got the doors back on the deck. put the rest of the segments on this side and then we'll build these idlers up.

[00:27:06]Slide the idlers back in. Put the chains on. No problem at all.

[00:27:13]Quite smooth operation.

[00:27:16]I mean, we only really did that to make life a little bit easier for the for the boys putting the rollers on. So, who who needs a pit when we got a wrecker?

[00:27:27]Let us know within the comments if you want to see us go out on some recovery missions in this or any other wreckers that Millers have because as long as the whether they're going out to recover, we'll allow it to be on camera. We might actually go out and do a few recovery operations with these men.

[00:27:52]Well, this is Luke set up his little rogue. Although you have just bought a warrior, aren't you? 330 big >> and a little torch.

[00:28:01]>> Little torch. Is it a good little set that >> belting?

[00:28:04]>> Belting.

[00:28:04]>> Yeah. Good on ball welding. Very good ball.

[00:28:07]>> Ah, doing it for line bing. Yeah. So, I just put some were bars on here now.

[00:28:11]Only need to be mild steel.

[00:28:14]Side bottom bottom side.

[00:28:20]But what are they? Six mill them.

[00:28:23]>> Yeah. Six.

[00:28:24]>> Yeah. 6 million.

[00:28:26]>> Might better just checking that the uh the harder should be, shouldn't it?

[00:28:31]>> Yeah.

[00:28:31]>> Yeah.

[00:28:33]>> A little bit of tolerance.

[00:28:34]>> Little bit of tolerance. So, we've just built the other side up now. The hardly put new seals in it on the rod and uh the cylinder. The dust seal was all right on the cylinder. So, that's built up now. This is the one that was passing and that was the seal that came out of it.

[00:28:54]You see it's damaged and it didn't have that white bit of seal on it. So, this track wouldn't pump up at this side all because of that.

[00:29:07]So, the rod's good to go again. We'll just wait for Luke to put the were bars on this side. Then we'll slide that in and uh and then it's ready for the tracks. But I'll just show you the process in here.

[00:29:23]as we're about to reseal this one.

[00:29:28]The seals are probably all right on this. Let's just have a quick nosy.

[00:29:32]Well, they're like >> Yeah. So, you can see that white seal's still there. So, it's not as bad, but we're not going to mess about. We'll just change it.

[00:29:44]Yeah. And two little seals there.

[00:29:48]Give that rod a good clean up. Bolt the new idler on them.

[00:30:24]That's how it should look.

[00:30:29]So, that'll just slide in there nicely now.

[00:30:35]Grease valve out.

[00:30:41]Should we put that in before? Ian, do you want to put either on first? Bang that in first.

[00:30:45]first.

[00:30:46]>> Yeah.

[00:30:47]>> Then put that in.

[00:30:50]>> So you got put this on afterwards.

[00:30:59]Should idle worn down. There's a little bit of movement in that. So good job of changing some idlers.

[00:31:10]Heat. Heat. N.

[00:31:20]Hey, hey, hey.

[00:32:03]Heat. Heat.

[00:32:39]Hello.

[00:32:39]Perfect.

[00:32:46]All cleaned out. Lock tight them bolts in there now with the pad on.

[00:32:53]This is my new front man by the way.

[00:32:55]People not seen him yet. We'll be seeing a lot more of him soon.

[00:33:10]So we use the sprocket with the strap just to pull the chain >> round.

[00:33:17]Lock it up at the other end.

[00:33:20]Plenty of lock tight and everything that you use.

[00:33:29]Job's a good one.

[00:33:34]Heat.

[00:33:47]Heat.

[00:34:04]So, she's ready. Well, the tracks are going to be a little bit tight till the bedied in.

[00:34:10]Yeah. So, it needs a good day's work.

[00:34:11]What I might do, I might spread get some of them planings out from over there and just spread them across yard. But I'll just track it now. You'll just listen to it be because the links are a little bit tight.

[00:34:24]The tracks aren't tight, but the links are tight till it's beded in.

[00:34:30]Hey Luke, this back race is new belted.

[00:34:34]Bit travels are good and still slows me down a little bit more.

[00:34:51]So, it doesn't sound too bad to be fair.

[00:35:34]Heat. Heat.

[00:35:41]Heat. Heat.

[00:36:12]So, I reckon we'll uh we'll get some playings out. We'll spread them across yard, track it a little bit. But what we'll do when we send it back to site, we'll go out after a day, just check everything, make everything's good. And after a week, we'll check the segment bolts are still tight.

[00:36:30]So, can you see how the links are a little bit up and down? That'll be just until the bedied in. Yeah, like I say, a day on site. We'll sort that job out.

[00:36:41]Ready for collection. So, I wanted to start this video on the dozer, but there was a little bit of work done before this doors are actually turned up. So, let's jump back to that bit of work that we did before I had this bad back.

[00:37:11]Heat. Heat.

[00:37:18]Heat. Heat.

[00:37:28]Heat.

[00:37:44]Heat.

[00:38:00]So that's them bits welded up. Quite a bit of welding went into that. And on the underside, put quite a few runs in.

[00:38:09]Fill it all up nice and strong.

[00:38:13]So now we're just going to make the two ends.

[00:38:16]And then we need to try and straighten that best we can. I need to take that lump out of it there because when this ram bracket goes ram guard goes back on that is catching. So I'll knock that in.

[00:38:30]Obviously we're not going to try and straighten all this up. Obviously we got to try and keep cost down a little bit.

[00:38:34]Um but as far as it goes you'll not get much better than that unless you want to spend a lot more money with obviously hardox material. We've only used mild steel here as the original was only mild steel.

[00:38:48]So, we got to make the two ends. Now, if you look, this was one of the ends before. It's only 10 mil.

[00:38:56]You can see what it like before, can't you?

[00:39:00]It ripped away. So, I thought I might just cut these by hand. Actually, get a piece of 15 mil off rack and uh just do with the hand plasma.

[00:39:13]Cut two ends, weld them on, straighten that up.

[00:39:17]Job done. If we got a bit of paint, I'll put a bit of paint on it. But I don't think we've got any that like chassis gray paint. So, I don't think customers too bothered about it being painted, but we'll see where we're at.

[00:39:43]Heat. Heat.

[00:40:05]Heat.

[00:40:16]Heat.

[00:40:39]Heat.

[00:40:46]Hey, heat. Hey, heat.

[00:40:50]Heat. Heat.

[00:41:30]So that is now the blade finished for the duck 14 ton duchon and Ryan the owner. How you doing pal? How we doing?

[00:41:42]>> Has actually just turned up.

[00:41:45]>> Tell us a little about this, bud. Was it uh Yeah. So machine's been on high four years. Um obviously >> four years.

[00:41:51]>> Four years. Yeah. So obviously he's done his work. So but they've uh trashed it as you seen. But um Baz and his gang have sorted it out very fast for us.

[00:42:00]Turned around in a week. So really happy with the service.

[00:42:03]>> Yeah. Well, when a when a machine is down, like I always say, if a machine's down, it has to be done quick. hitch over there that's coming. That has to be done quick because the machine's going back out on Are you going back down to fit this now?

[00:42:14]>> Yeah, it's got to be fitted by 3:00 today.

[00:42:16]>> 3:00 today?

[00:42:16]>> Yeah.

[00:42:17]>> In Southampton.

[00:42:19]>> Southampton.

[00:42:19]>> Yeah. Southampton. Yeah. Yeah. So, that be fitted today. We'll have a happy customer.

[00:42:23]>> So, I have a rate of 1 to 10. What would you rate Well farmer?

[00:42:27]>> Fantastic. 10 10 out of 10.

[00:42:28]>> 10 out of 10.

[00:42:29]>> Service great product. Who's that on there?

[00:42:36]>> Is he your f?

[00:42:37]>> Yeah. Yeah. bit. Yeah. So, yeah, second set of hands.

[00:42:40]>> The only thing you might have a bit of fckling with is the ram guard.

[00:42:44]Obviously, I've I've kind of guessed that getting it straight. Yeah.

[00:42:47]>> Do you know what I mean? So, it might just be a few hammers here and there to >> just get that to fit on site, but other than that, everything else shouldn't be a problem at all. Spot on.

[00:42:56]>> All right. P LMC plant and site services. How much tackle have you got?

[00:43:00]>> Uh, so we got a few machines, but we predominantly do um sort of breakdowns and service repair really.

[00:43:06]>> Oh, yeah.

[00:43:06]>> So, yeah. Yeah.

[00:43:07]sound. So, how many machines you got on here? Just a few.

[00:43:10]>> Uh, about eight at the minute.

[00:43:11]>> Eight.

[00:43:12]>> So, yeah. Yeah. So, >> 14 tons with track skid steers and bits and pieces like that.

[00:43:18]>> It's always good to meet customers around the country, especially from all way down south. What made you come up here?

[00:43:23]>> Just your feeds and watching you and the quality of the work. So, needed something done properly.

[00:43:27]>> YouTube or Instagram?

[00:43:28]>> Uh, Instagram.

[00:43:29]>> Instagram. Yeah.

[00:43:30]>> Yeah. It's always good for us to find out as well where the the work comes from. Do you know it's like things just turn up here. They don't even know they're coming.

[00:43:38]Do you know what I mean? So, yeah, I'm pleased. You're happy with that, bud?

[00:43:41]We'll get you loaded and you can get back on the road. All right. Thank you very much.

[00:43:45]>> So, big thanks to Ryan. Cheers, pal.

[00:43:48]Appreciate the work of you men. Now, then all loves a bit of gouging, don't you?

[00:43:56]>> So, looking at this lenov hitch now, we need to go right over it. We get a torch at van. A good inspection. From what I've seen so far, we need to reweld all these points here.

[00:44:14]Someone someone's >> someone's attacked it there.

[00:44:19]We'll take both sides out. Yeah, cuz it's obviously been failing at that point. Right.

[00:44:25]And underneath the hitch where the plate goes on there a couple of cracks.

[00:44:34]>> You see here? Big crack there. Yeah.

[00:44:39]And a big crack there.

[00:44:45]>> Yeah.

[00:44:46]>> Yeah.

[00:44:48]>> Try and get these studs out as well.

[00:44:51]You all right? Studs.

[00:44:53]>> Yeah.

[00:44:53]>> Yeah.

[00:44:55]Good way of extracting that would be to tack a washer on it, then tack a nut onto the washer, wind it out.

[00:45:05]Yeah. We'll be very careful with the all this.

[00:45:10]>> Yeah.

[00:45:10]>> Yeah. With the uh with the sparks and stuff.

[00:45:13]Um in fact, you probably could try the new gouging gun.

[00:45:17]>> Yeah.

[00:45:17]>> Do you want to try that?

[00:45:18]>> Yeah, definitely.

[00:45:19]>> Where is it? Here we go.

[00:45:22]or hyperfirm 85.

[00:45:26]We bought the new gouging gun on the sink.

[00:45:29]So, it's set at 15 degrees that so it's a lot easier for blowing out.

[00:45:34]You know, if you're blowing up there, dead easy.

[00:45:38]So, give that a whirl.

[00:45:41]>> I know you like our curing, but try that for today. Yeah. too many eyeballs.

[00:45:48]>> Our caring, there's a lot more material going to come off a lot faster, but because there's so many parts on there, unless we strip it down completely, um, which we don't really need to do for the for the amount of cracks that are in it, unless we find some others, >> good check with torch.

[00:46:04]>> Yeah.

[00:46:05]>> Yeah. All right. So, there's that. I've got to go and do a welding job on site on a crane today that can't be filmed.

[00:46:12]So, we've cut the plates on the plasma.

[00:46:15]Um, I'll head over there and do that shortly. I'll set a camera up on you.

[00:46:19]All right. The other two boys are still on the vans.

[00:46:23]This is challenge and fear is totally the absence of love.

[00:46:36]All right. Uh so what started off as a routine crack that we were just going to gouge out and weld it up has now turned into a bigger job a lot bigger job. So as you can see here gouge this out to get this crack originally and now we can see one's formed here right round and through but the welding oh it's gone up there as well.

[00:46:57]Same other side.

[00:47:00]Yeah this could be down to not being preheated when it originally done or repaired previously.

[00:47:05]So a bit of a trial and error thing. We can just keep gouging and see where we get to with it.

[00:47:43]Heat. Heat.

[00:47:50]Heat up here.

[00:48:29]Heat. Heat.

[00:48:53]Love is light.

[00:49:19]Love.

[00:49:32]So, I've just landed back in the workshop.

[00:49:35]That would have been a good job actually, director, but we weren't allowed to put it on camera.

[00:49:41]But you've done a lot of gouging there, all with that new uh >> that will b on. That really works.

[00:49:48]>> You like it?

[00:49:49]>> Yeah. Yeah, they are good if set at 15° them gouging guns for hypermir. And uh but when you sent me the pictures whilst I was on that job, I could tell it needed a lot more material out of it.

[00:50:02]That's why you need to jump onto arcer.

[00:50:03]Yeah, the arcer just takes so much more out when you're using this gun.

[00:50:08]>> So now you got to bottom of the wall.

[00:50:11]Just keep heating it and you like a spider's web.

[00:50:15]>> Yeah. Yeah. Some in like that. Not in that size.

[00:50:18]>> Yeah.

[00:50:19]>> It literally like like it were fractured. Started off a little then just sprayed out. I've got I've got them all.

[00:50:26]>> Yeah.

[00:50:28]Right. So that side's nice and not in it. Get it flipped on its side. Let's get try and get as much welding to that as we can. When we flip it back over, we'll preheat that side again. Have a little quick Have a little sweep up. Get welding. Yeah.

[00:51:22]Heat. Heat.

[00:51:30]The same is true.

[00:51:51]Love is existential.

[00:51:55]So >> that's a Lenoff hitch repair done.

[00:52:02]probably got a little bit over the top there, but once again, always better going over top. We took as much as possible out as we we could as you saw earlier with how much we took out and then built it back up to a flat position and then obviously we've capped it with multi-runs. So, there's more runs on there than original.

[00:52:23]We'll just have to hope that we got uh basically to the root of the problem.

[00:52:28]So, I'm hoping that'll be all right. So, it's going on a big machine.

[00:52:33]So, this pulverizer is just coming from Howard stock. We'll jump on this shortly, but we got to get on with that crushing bucket first really. And I've just had a call to go out to lance a pin out. So, I think we'll put an end on this video for this week. Might be a short one. Cheers guys. Thanks for watching. Don't forget to hit that like button. We'll catch you on the next one.
