Speaker A
Welcome back. This is part 10 of restoring my dream power hammer. We've got 17 days to go before 30 tons of concrete is cured, and I can install this 67-year-old piece of British history. This is the standard. Today, we need to work on the lower half, the base plate. So, it's time for a little workshop shuffle.
Speaker A
There we go. Look at that, Jamie. Thank goodness I went to all that effort of sealing it from not getting any dust in.
Speaker A
Okay, you know what's funny about this? My neighbor Steve, right? He's got engines apart all the time. He knows cars back to front, left and sideways, upside down. He did tell me before this, "Oh no, I'll never let grit blasting go anywhere near an engine. Even trying to seal it off, you'll never keep the grit out." And I thought, "Yeah, that makes sense." But I'll give it a try anyway.
Speaker A
It's worth it. Look at this beautiful paint job we've got. It's worth having to hoover up a bit of grit.
Speaker A
It's weird how it's made like a weird symbol or something there. Oh yeah. Isn't that funny?
Speaker A
Look how much of it there is. That's crazy. I think we might be blocked.
Speaker A
That's got a face on it as well. I don't want the coincidence. What do you reckon, Jim? You would eat your dinner out of that?
Speaker A
It's a bit better, is it? But would you eat your dinner out of it?
Speaker A
I'm not sure if I'd eat my dinner out of it. Breakfast? I'd eat my breakfast out of it. Yeah.
Speaker A
Oh, good. Big improvement. I did have it in my mind to now go ahead and start assembling the flywheel components, but then I realized, haha, I then won't be able to mess with the oiler. Right here in the machine is the heart of its continued operation. And that is the lubricator. See, up to about this level, this tank is filled with oil. And this lubricator lives right there, actuated by a cam on the spinning flywheel crankshaft, sucking oil up through the bottom of it, pumping it through this larger bore line before it gets filtered and sent to the rest of the machine. We got to fix the oiler while we still have access.
Speaker A
It's like being at the aquarium. Now, I have no reason to suspect that this wasn't working at its last operation, but considering how rusted that little piston is there, I think the whole thing does need to come completely apart. I can't just clean it up and shove it back in because I presume that that piston wants to be a proper leak-proof seal between it [music] and the bore because it is this that goes up and down pumping the oil. Apart you come. Mike could need a vice. See what secrets you hold.
Speaker A
Okay. Explain that to me, Jamie. How did that get in there in the first place? If it fouls on that. Oh, just that's strange.
Speaker A
Any secrets? No secrets. I think that might be like a pressure relief thing. Any [music] secrets?
Speaker A
It's not the chamber of secrets in there, right? Not off to a good start.
Speaker A
Well, this is the main bit, but like how the hell do you get it off?
Speaker A
I don't know. Maybe it's threaded. Not exactly like a nice way of Oh, it looks like it [music] could be threaded actually.
Speaker A
Yeah. What? The way a little bit of it protrudes, you mean? Yeah, but it almost kind of looks like a thread.
Speaker A
Oh, yeah. I think you're right. Oh, yuck. Well, it's not spinning now. I'm getting bad, bad vibes from this thing, Jamie.
Speaker A
Why? And as I look across to that, the vibes get worse. More I look at this, I'm not feeling happier.
Speaker A
My mouth's drawn. I can't just disturb John at every single opportunity. This looks like that shaft and this flange is one, one piece. There's a nice radius and I can't find any gap where it joins. So, this must be hollow.
Speaker A
And that runs through it. It still could be threaded. Oh, there was a ball poking up here and now I've pushed it down.
Speaker A
Yes. Look at that. It was frozen in the shut position. Brilliant news. Well, there's some relief. That's good for the soul, isn't it? High five. Oh, yes. Out comes our piston. Oo, beautiful.
Speaker A
This looks way less daunting now. Yep. Much better feelings at the moment, guys. And it all looks quite lovely in there.
Speaker A
I'm impressed with how little wear it looks like this thing has considering the motor pushes it up and down 140 times a minute. I think this little fella is a pressure relief valve so you don't go blowing up the oil lines.
Speaker A
Looks like there's a little ball in there. And I think this screw pushes on a spring against that ball, which means that if this pumps too much pressure or there's a blockage, at least it's not just going to be building up and building up and building up pressure until it blows up. It has a tapered pin running through the side of it, presumably so that the tension can be set in the factory. But we're going to need to get rid of that so that we can clean the inside. Oh, miracles do happen. That is the easiest taper pin I have ever extracted.
Speaker A
Taa. Yummy. See a ball in there? Mhm. Is that malt teaser? Yeah. You want one?
Speaker A
Oh yeah, that's so strange. Why? Because I literally clean my butthole like that muzzle. [laughter] Okay, so here are all our components.
Speaker A
I'd say it looks rather, rather fine in there. Thankfully, everything that was completely sealed on this hammer kind of survived, especially if it had a healthy coating of oil. Anything that was exposed to the atmosphere, as we saw on the shaft of this piston here up there, just nasty thick rust. But I got the high spots off and hopefully we'll have a feel of a nice fit.
Speaker A
Yes, not too crunchy and yep, drawing suction, which is exactly what we want. And the way this is arranged, this has some ball bearings in it. You can just about see it inside the end of the shaft there. I can't tell if it's one or two ball bearings. Now, this one appears to be in fairly good nick. However, if we look at our pressure relief valve, the ball bearing that lived inside it looks, as Jamie pointed out, more like a malt teaser than a nice ball bearing.
Speaker A
Look at that ring of rust around it. Not quite as catchy as ring around the posies, is it Jamie?
Speaker A
But on my previous Massey Power Hammer, we've also had ball bearing problems. Rusty balls is something that we've been around a time or two, haven't we, Jamie?
Speaker A
Speak for yourself, mate. Were you not there that day? Yeah, I was. Yeah. So, I do have a pack of balls.
Speaker A
However, the new ball is a lot smaller than the old ball. Will it work? I don't know. Will it just pass straight through? I think it's going to work just fine. Expert opinion, Jamie.
Speaker A
I don't know, mate. Surely it needs to be big enough to give it a seal.
Speaker A
Yeah, but I mean, a ball's a ball to give it a—That was an aquatic joke. Mating surface on there. Looks so—So, don't really know what angle that little chamfer should be ground to. Also, don't know how to tell if this is going to seal and hold pressure. Maybe I need to suck on it. You know, vacuum pump. That's how I can test it.
Speaker A
A lot of suck on it. That's what he said. Does appear like it's holding a vacuum.
Speaker A
My scientific test tells me it's not quite holding so well here. Sounds like it is.
Speaker A
No, I can just tell. Where did I put the piston? There. Oh, that one maybe is holding a bit better.
Speaker A
M. I'm a bit skeptical about the quality of the seat. So, apparently the thing to do to get a proper seat is drop that in there. Hardened ball, hardened ball should deform the seat enough.
Speaker A
Yep, that's sealing. Go. One more for good measure. All right, there's one. Now, the ball bearings in here are super corroded. So, I think there's a bronze bung that holds the ball in. And I want to get that bung out so we can replace the ball. So, I'm hoping this just falls out as we heat up the outside. Loud noise.
Speaker A
That'll be a negatory. I was thinking, you just know where this is going to just fall out.
Speaker A
You wouldn't have been chuckling if it had. As a man who spent many, many hours taking apart rusted manky things, I can't believe you'd even think that would be possible.
Speaker A
I see the old insult compliment. [laughter] I need just the perfect thing that'll fit down there that I can tippy tap away on.
Speaker A
[music] Did it move? No. No. Anything? It's not even lik
Speaker A
seal and hold pressure. Maybe I need to suck on it. You know, vacuum pump. That's how I can test it.
Speaker A
A lot of suck on it. That's what he said. Does appear like it's holding a vacuum.
Speaker A
My scientific test tells me it's not quite holding so well here. Sounds like it is.
Speaker A
No, I could I can just tell. Where did I put the piston? There. Oh, that one maybe is holding a bit better.
Speaker A
M. I'm a bit skeptical about the quality of the seat. So, apparently the thing to do to get a proper seat is drop that in there. Hardened ball, hardened ball should deform the seat enough.
Speaker A
Yep, that's ceiling. Go. One more for good measure. All right, there's one. Now, the ball bearings in here are super corroded. So, I think there's a bronze bung that holds the ball in. And I want to get that bung
Speaker A

Speaker A
I see the old insult compliment. [laughter] I need just the perfect thing that'll fit down there that I can tippy tap away on.
Speaker A
[music] Did it move? No. No. Anything? It's not even like contemplating it. Like it's not even thinking about potentially moving.
Speaker A
Right. Thanks, Jamie. How about some good news once in a while? I don't know.
Speaker A
What was that supposed to do? Oh, I'm testing cuz what I'm going to do is I'm going to heat up this whole thing and then once it's warm, I'm going to try and cool down the little just the
Speaker A
little bung. So, everything else will be hot and then I'll shrink the bung and it'll it'll drop right out. Just you wait. We should shrink the bun.
Speaker A
What's strange about shrinking the bung? It just sounds funny. Oh, you're not going to be laughing when this drops out now, Jamie. You see it bubbling. Oh, yeah. Ready? Loud noise.
Speaker A
All right. Shrink the bung. Okay. Knock it out from the top. Oh, it's moving. It's It's about to FALL OUT. YEAH, MATE.
Speaker A
I was having your mate. It hasn't moved at all. You're a [laughter] Why did you do that to me? I'm so excited.
Speaker A
Jamie, for us on this power hammer, having a filter to scrub out any debris from the oil, capture it, and keep it helps keep the hammer running safe. But there exists data brokers and harmful sites that do a similar scrubbing,
Speaker A
scouring the internet for your data, collecting it, aggregating and selling a data profile about you to advertisers, creditors, criminals, or stalkers. There are thousands of these data brokers worldwide. And what today's sponsor, Incognito, does is it automates removal
Speaker A
requests across 420 plus of these harmful sites. This information can be your home address, your workplace, your phone number, email addresses, and attackers are using data brokers to find victims. Instead of manually going through the process of finding these

Speaker A
You know what they say, Jamie. More heat. Can't believe you do that to me. That's outrageous.
Speaker A
I think I've deformed the bit of bronze in there. It look like there's a divot.
Speaker A
There's a bloody divot. Not coming easy. On the bright side, guys, I now don't need to worry about getting that piece of bronze or brass out cleanly. I can just completely destroy it cuz I've already destroyed it. We'll just have to
Speaker A
make a new piece. While that cools down so I can get a drill on it, let's see if we can get this one out without destroying it.
Speaker A
This one won't come out either. Nope. How about penetrating oil? Yeah, right. Just a dab of penetrating oil. This interference fit will just come right off. It won't. So, this fell has been press fit in there. I can't get
Speaker A
enough of a heat difference between the steel [music] and the brass or bronze to make the steel expand more than the brass or bronze, allowing us to then have some clearance to pull it out. Got the same problem on this fella here. So,
Speaker A
I think I'm just going to drill them out. Since it's bronze, I'm going to flatten off the edge so it doesn't bite in. Tip that we learned from you guys in the comments.
Speaker A
Don't know what my game plan is after the drilling. Haven't got that far yet.
Speaker A
The whole reason we're doing this is I need to replace that ball cuz both those balls are rusted. Hello.
Speaker A
It's going delightfully, isn't it? We're going to try and make it so the ball at least comes out with the bur and then I'll be able to get a drill through it easier.
Speaker A
[music] Well, damn it. That ball actually [music] looks in really good condition. It [laughter] looks a lot less rusted now. Look at that thing. It may be discolored, but it looks perfectly smooth.
Speaker A
This is more complex than I imagined. It is not simply one small little washer, as I thought it was. It's actually a complicated bit of bronze that sits much deeper. I'll sketch what I thought it was. And I'll sketch what I think it is.
Speaker A
Now, this is how I thought it was. Steel, a pin back here to stop the ball running backwards, and then one small little brass or bronze washer with a hole in it. In fact, I think it's like this. A long brass sleeve that has a
Speaker A
machined recess here to stop the ball coming out [music] of the front. And I have now destroyed the front of this recess, meaning that the [music] sleeve back there in bronze or brass is still in place. So, what I'm going to have to
Speaker A
do is put this in the lathe and come in here with a boring bar and work inwards, making a [music] new little flat face up to which I can press a new round disc with a [music] hole in. That
Speaker A
unfortunately makes this even easier to cook up than it already was. It's probably the same on the other one, isn't it? Now, which makes that worrying cuz that can't go in the lathe. That's another hiccup in our road. And time is
Speaker A
ticking. Oh, hello. Yeah. What is happening here? Eh. Oo. Hello. I like how that's looking.
Speaker A
[music] [music] That will hopefully seal out of the lathe. This is the face that the ball bearing will sit against. And now that I'm looking inside that hole at that little bit of shaft, I am worried that this ball bearing is maybe going to
Speaker A
get No, it's fine. It's not going to get stuck cuz [music] this ball is a little bit smaller. I was worried it might get stuck down there, but I don't think we're going to have any issues at all.
Speaker A
So, the hope is is that this doesn't fit at the moment. I don't know why I would try and press it in there cuz now I have to wrestle to get it. Why would I do that?
Speaker A
How about you drill it out? Make another one. No, we're not going to do that. Why would I push it in there with force when it's not the time?
Speaker A
See if it's cold enough. Classic. [music] Is the ball inside? I hope the ball's inside. So, that is a 40 micron interference fit. Hopefully, it stays in there for as long as I own the hammer. Hopefully, it still seals as
Speaker A
well. It seals. We can now get back to this. We got to try and get that bit of bronze out since I ruined it. The ball is probably going to be perfectly fine, but we're still going to replace it with
Speaker A
a fresh one. We threw the bronze to the iron. Try and get our ball out.
Speaker A
Oh, where did it go? Why does time move so quickly? Okay, freezer time. [music] Ah, super.
Speaker A
Not quite flush, is it? No, I made it tiny bit proud. The original was a little bit proud as well.
Speaker A
And did I put the ball in? I did indeed. The ball is in. And while I was in the freezer shrinking, we made a list to see all the things we've got to do in the next 15 days. It is
Speaker A
dauntingly long. And in fact, I ran out of space. That is a serious list. I don't like the look of that, guys. I want to be forging in 15 days. And this doesn't look like I'm going to be able
Speaker A
to forge in 15 days. We're going to keep working as if we are as fast as possible and as much as possible. Yeah, we're going to be pulling some 24-hour shifts, I bet. Right now, on the oiler, I will
Speaker A
say this is a delightfully simple design. There's one spring to fail and then it's just a couple of balls which are a headache to replace. It's not really designed for servicing, but presumably if it's not left out in the
Speaker A
elements for 20 years, it's got a nice healthy coating of oil, those uh those balls would have never rusted and corroded. I've been trying to figure out exactly how it works. So, this piston is going up and down inside that ball.
Speaker A
There's that one ball check valve at the bottom. The piston also has a ball check valve at the bottom. I presume what's happening is is that as this goes down, the ball then seats in the check valve here. As it lifts with this spring
Speaker A
tension, it draws oil into the bottom of the chamber. The pressure of which closes this ball check valve. As this then closes again, that oil flows into this fella right here. And then as it lifts with the spring tension, it draws
Speaker A
more oil into this chamber. And then as it goes down that I Yeah, I don't still don't exactly understand the uh how it works other than check valves go open open closey closy sucky sucky pushy pushy. Anyway, this filler must
Speaker A
have picked up some uh debris in its life from the bottom of the old tanks.
Speaker A
It's got a good few dents and scratches on it. We'll see if we can feel any high spots.
Speaker A
So, let's have a look and see if it works. I think it is the spring that does all the work. Obviously, the crankshaft pushes it down, but the spring pushes it up. And I think it's that springs actually doing the pumping.
Speaker A
Bit tight to get in. Oh, yes. Sick. Listen to this. It does some sucking. Get in. That is just so much smoother than it was.
Speaker A
Brilliant. I think we've rebuilt an oiler, but there's only one way to know for sure. We need to test it. Let's assemble our pressure relief valve. That also gets a brand new fresh ball. The original spring seems totally fine. Put
Speaker A
a little bit of oil in it. With the ball in place, I can screw this fell in. That spring will start pushing on the ball until my groove for my tapered pin lines up. Reinstall that fella. Meaning that
Speaker A
the pressure applied to the ball is now Oh, I have a different size ball. So, the pressure is going to be different.
Speaker A
H. Well, anyway, as a matter of curiosity, what I want to do now is I want to see how much pressure is required to open the valve. a lot more pressure than I can apply. I wonder how much additional tension is being applied
Speaker A
to it. The original ball was 12.7 mm. New ball 10.3 mm. That means that that spring is applying 2.3 mm less force on it. I've got an absolutely brilliant idea. I'm biased cuz it's my idea. But do you mind sharing this idea?
Speaker A
I will share. It's it's phenomenal. It's the best idea. You've never seen an idea like it. We know the difference in ball size, right?
Speaker A
All I have to do is put a spacer in. And it's that difference. So, I'll put the spacer at the bottom of that hole. A 2.3 mm spacer. That's good, isn't it?
Speaker A
Super good. Thank you. Okay. I don't think that's going anywhere. I've locked that copper in with some center punch marks. So, our spring is now not going to know the difference between the new ball and the old ball. It's a ruse.
Speaker A
That lines up. Pressure relief valve fixed. Super. As much as we've had a battle with these ball bearings, this oiler design is fantastic. Compared to all of the other oilers that I have been around on power hammers, I think this wins.
Speaker A
This is fabulously simple. It's two ball bearings, a bit of machining, and it's constantly immersed in oil. Oh, one pressure relief valve. Bellisimo.
Speaker A
Oh, let's test it out. Yeah. See how she does. I'm going to put a little PTFE.
Speaker A
Kind of be just called blocky tapy. It is locky tapy. Actually, that's the technical word. PTFE is just a nickname.
Speaker A
It stands for please tidy fixy everything. Locky tapy is the technical one though. Look at that. No way. Listen. It made a farting noise. Okay. Ready? There is a tiny hole that passes the whole way through.
Speaker A
THERE. OH, THIS is even cooler. that pumps oil up the center of that shaft onto this surface so that you lubricate the contact point between this AND THE EAST AND the crankshaft that is pushing it up and down so it's constantly flooded with
Speaker A
oil. That is some spectacular design work. The oiler lubricates itself. Do you ever just like get emotional about beautiful simple engineering? I could cry. This is our ultra super duper special massie oil.
Speaker A
That's one stroke. Second stroke. It's already happening. Oh yeah, it's having a really nice effect of actually flushing all the debris that we couldn't get out. So this uh what is very clean and very expensive oil is now
Speaker A
getting dirty. God, this is awesome. What an amazing oiler. Hopefully, it's nice and clean now. Oh, you know what I didn't test? Actually, let me fill it back up with oil. I didn't test to see if we could get our pressure relief
Speaker A
valve to uh fire. Yeah. So, let me put my finger on it. Oh, look. When there's resistance, it pours out the top. Okay. So, now I have to hold that, too. Oh, there's another there's another squirting hole. Look at
Speaker A
that. Ready? Yeah. You need my help? YEAH. NO, [laughter] it went everywhere. All over the shop. Literally, I'm not going to play with the pressure relief valve anymore. It's just making a mess. That's all the bronze shavings from when I was
Speaker A
trying to drill out the original bits of bronze. I I mean, I degased and blew it out a good deal, but obviously not well enough. This is why I try to be so bloody careful about contamination and try and clean things as much as possible
Speaker A
because as much as you try to clean stuff, it's still going to be there. So, you might as well give it the best shot possible cuz you'll never get it all. We come back to the base plate and flush
Speaker A
all these lines. Let's make sure that these are clean. [music] So, I'm going to plug up these oil filter spots with things that I luckily happen to have on the shelf because I'm a hoarder. That way, the oil won't come
Speaker A
out of here and we can flush it through all the lines totally and properly.
Speaker A
Let's get pumping. [music] Wa. Got to watch out for that, don't we? There's incredible amount of volume it pumps with every pump. And imagine this is going up and down 140 times A MINUTE.
Speaker A
WA NO. My check valve appears to not Oh, I had this valve open. That looks remarkably clean. Oh no. Why did I go to all this trouble? Oh yeah, that's a good bit of dirt. Yes. Now we're getting some
Speaker A
good debris flowing through. Okay, it's definitely worth doing this. All that would have just been inside the hammer otherwise. Yep, that's some good sediment. Yummy. Glad we got that out of there. Another little purge.
Speaker A
Now drain this fella. Brilliant. All right, let's bring the oiler home. Some nice shiny clean bolts for you, old pal.
Speaker A
Sure. I'm glad we messed with this before we put the flywheel in. Imagine what a pain in the butt it would be to fix this oiler through this manhole in the standard. Oh gosh. With the oiler done, it's time to work on what lives in
Speaker A
these two holes. Remember, they line up with this little bulge there. So, the oil pumps into the bottom and then out the top to the bearings and to the cylinders. If we consult our manual, you'll see that we're looking for part
Speaker A
56 and 55. A magnetic oil filter and plug and auto clean strainer, also written as L and M. And this is the information I got to digest.
Speaker A
No, I can't. Let's just have a look at the real components, shall we? This is object L, our oil filter. And this is object M, our magnetic oil filter. You can tell because it's magnetic. As you can see, our Autoclean strainer has seen
Speaker A
better [music] days. It's bent. It's meant to be able to spin. It doesn't. It's also very dirty. Our magnetic filter is also incredibly dirty and very hard to clean because it's magnetic. It says taking off the brass nut at the
Speaker A
outer end of the filter, after which the sleeve surrounding the magnet can be pulled off. By the way, special thank you to Kipex. I did just have these and now I've got all of those more Kipex than I'll know what to do with. I should
Speaker A
be able to. Now it's all coming off. Okay. I totally made a mountain out of Molehill on this component. That is ready to go. Tighten you up. Yeah. This is just basically a magnet to sort out any of the iron
Speaker A
particulate. She will live right there. This is just a temporary installation. I need to see um how far it goes in. I'm going to have to make a gasket for it to seal. How good is that going to look
Speaker A
against the blue? Beautiful. I certainly think this fella is going to be more mountain than Molehill, though. This is what is called an auto clean strainer. And in fact, it's stamped here on the side of that little flange. This company is still in
Speaker A
existence, which is awesome. 100 years of oil filtration. Where it works is as follows. This handle is meant to twist.
Speaker A
It didn't twist until I loosened that little nut right there. And now it kind [music] of twists. Upon these square rods used to exist an absolute stack of these fellas, little 5,000 steel shims that protruded into this stack of discs.
Speaker A
That stack of discs acted as the filter. The oil would come up through the oil filter sump, be forced through those discs, out the center of this tube, through and across into these oil lines to feed the hammer. Those scrapers are
Speaker A
there on those square rods so that you can twist the filter stack against them, make the debris drop down and get caught by our magnetic filter. Since the company's still in existence, I gave him a call and they said, "Yeah, sure. Send
Speaker A
me some pictures. I'll see what we can do." So, we might be able to either get this efficiently refurbished or buy a brand new one. However, if I had to make a guess as to how expensive a brand new
Speaker A
one of these is going to be, considering how obscure and unique this thing looks, I'm guessing this is about 650 quid to buy a new one. I wouldn't be surprised if this is 1,000 bucks. Let's hope it's less. But I have to wait for that email
Speaker A
to come back to hear what our next steps are on our auto clean strainer. So, while that's on pause, let's begin with some other tasks. How about the uh the task I set out on doing at the start of
Speaker A
the video? Flywheel crankshaft at last. Woo! Ain't she beautiful? This one, two, three, our three most important bearing journals. This plate that's straggling along here exists only to stop oil from splashing out of here and dribbling down to the ground. And
Speaker A
that is achieved through a felt seal that is stuffed in that gap with this plate. All this will be rotated like that and positioned over this portion of the shaft. So, while this was never a ground surface, it was just a turn
Speaker A
surface, it is not a bearing journal, it does want to be a little bit smoother than this pitted finish from being exposed to the elements for so long.
Speaker A
Amazingly, you I know. Isn't that cool? You can order half2in felt online only in packs of 10. It wasn't that expensive, though. That was only £43 for that whole pack. This will be our new felt seal to go around this, but that is
Speaker A
just going to araid it to hell and back. So, I'm going to see if our first task can't be smoothing this out a little bit. So, we can put all these back there and then start working on the journals.
Speaker A
Oh, yeah, baby. [music] That worked a treat. Much smoother. It's obviously still hella pitting, but at least things aren't as proud as they were a few moments ago. Let's stuff it.
Speaker A
Well, that doesn't look very square, does it? It's got angles to it. Don't know whether to go like grain against shaft or grain perpendicular to shaft.
Speaker A
I'm sure somebody knows. Oh, you got to do grain against No, no, no. Grain grain on.
Speaker A
I'm going to saturate this in oil cuz I think that sounds like a good idea.
Speaker A
Oh yeah. In you go. Now I'll screw this cover on. Now I'll slip this into its location.
Speaker A
Oh no, it doesn't go now. No, that means I have to install it here with zero access or it's really tight cuz I now can't slip it onto the other one.
Speaker A
There we go. Felt seal done. Does that mean not on the list? Is it what? Is it not? Might have been on the ground list. Damn it. I didn't put it on the list. I might not be able
Speaker A
to tick off what I've just done, but we can takeick off the oiler. Oh, hey, by the way, see this fella right here? That is the eccentric that drives the oiler.
Speaker A
And conveniently, that's the next [music] thing that I'm going to look at. So, it's that that is doing the on the oiler up and down 140 times a minute.
Speaker A
Now, it's not a bearing journal. It's plenty lubricated. It probably would have been [music] ground. It's now very rusted, but I will polish it up.
Speaker A
M. So shiny. Kind of like a 50% [music] rust, 50% shine. More space for oil.
Speaker A
Rust is a state of mind. And time is relative. Yeah. Doesn't feel very relative looking at that countdown. Now I'm going to hit our three journals with a little bit of emory. Just little buff up before we bring the bearing shells to it. Let's go
Speaker A
get some bearing shells. Heavy. What we now need to do is get all of these fellas clean. Bring them across to our shaft. Have a feel of how much slop there is. Potentially we'll need to apply some Prussian blue. Scrape these
Speaker A
uh shells back into a position where they have more contact so that there is no slop in any of these bearings. Please do go get 60% off an annual plan from today's sponsor at incogn.com/allexteel.
