It's not quite apples to oranges but REX chain company did lubrication tests many decades ago and their results showed that an unlubricated chain has about 600 times the wear rate of a properly lubricated chain. Oil/grease is cheap and works... very well. I constantly fight with customers to get them to throw even a few drops of oil on chains, let alone properly lubricating them. Downtime in my industry costs about $ 25,000 per hour and I have seen days of downtime caused by not using fifty cents worth of oil.
I bought a $300 electric grease gun. I gave them a ring with 6 sheet of lamented paper showing exactly where the grease fittings were. There was 17 on this machine. I told them in the morning grease it before the shift. I come back 2 weeks later... Well the grease guns battery is dead I cant grease anything... I mean you can only do so much.
Looks to me like the tractor fifth wheel jaw was also well out of adjustment. The driver must have been aware of the play between the tractor and trailer every time he slowed down or accelerated (clonk, clonk). At least people who decide not to maintain stuff like this ensures work keeps coming your way. Love your jobs, thank you.
I have a friend who has a construction and demolition company. He changes the colors of the grease he uses so he can tell if people are greasing or not greasing the equipment.
This very sad see this but that way is sometime.i work coal 1980-88 as serviceman se bc and they are tough on this.they said" grease is cheap but parts are costly" you got good point there.i work on trailers banister pipeline some 30 years look near new due money spend on maintenance.thank expose this thing.😮
Greg is not BS ing about those 3M Cubitron ll discs.... I have been using for over 5 years now and the 36 grit removes metal very very fast and gives a smooth finish.... I use on hot rolled structural steel we use for making mobile bars for hotels and they have to look like furniture.... no chattering on bouncing around on the material.... Greg knows his Grinding Discs...... cheers, Paul
Brings back memories , I’ve done some many of those things back when I started. But with a torch and and old hobart welder with jet rods!! Man how things have changed for the better. Great job!
Those cubitron discs are really that good. The old timer I wrench under handed me a handheld grinder with one of those discs when I was angling a piece to join on a large bench grinder. So much better. It's the mobility of a handheld tool with more cutting power and precision than the benchtop. It's the new OG stuff, you recommend it because it is absolutely the best.
I work at a Cat dealership and unless we need to dig something out with a hard stone we majnly use the cubitron sanding disks for everything. They are awesome!!
Great work!!! Not trying to publicly blast...just asking a question to learn. Do the craters left behind by the carbon arc gouging process weaken the base plate?
Great job on the replacement love the vids. One thing you do not grease the king pin , the jaws are out of adjustment on the 5h wheel. Many many fith wheels today use a Teflon or wear plate no grease whatsoever. Only place that gets greased is the side pins and jaw mechanism. You can see how the top of the pin is worn as well, the adjustment on the fith wheel is gone most likely the jaws are complete junk, and has been out of speck and illegal for some time.
@OFW they need to check and maintain adjustments, the driver who drove that trailer should have been screaming something was wrong just a small amount out creates a noticeable clunk also ruins the truck.
Just amazes me...the lack of simple maintenance and a little bit of TLC...if they made the damn operators go out there with you on repairs (and act as your handimen and gofers)...I bet they would take more pride in just pointing the equipment down the road...they aren't operators...they are just drivers Ah well...job security for a good welder! You need a sticker that says "I'm here because you broke something!" Keep em coming!!!!
I have gotten to the point, if I see a no grease situation.... .I have no respect for the owner and do not want to do the job.... .cheers my friend, Paul in Florida,
AirArc is just awsome I watched a Russian dude cut a massive steel roller his rods must have been 10 ft long and he spend all day cutting this thing into giant chunks lol I've been binge watching now for two days On Fire Weilding is at the Top of his game one of the very best I've seen on YT God bless O F W 💫✝️✨
I run my suitcase off of a bobcat instead of a big blue, I would be interested to see you test out live voltage readings with certain lengths of lead connected to it. It is surprising how much voltage drop occurs between my powerplant & suitcase depending on if I have 4/0, 2/0, or 1/0 connected, and 50' or 100' of lead.
We can hope that they figure out that it’s cheaper to grease things every once in a while. So that they don’t have to call you. I greased my truck every 10,000 miles weather it needed it or not, when I sold it 1,125,000 miles on the original kingpins and bushings. 5th wheel needed to be rebuilt & I greased it every once in a while. Thank you Sir for the video
That cubitron abrasive pad, how well does it work grinding along its own plane? I mean along its edge. Say for example I have an interior fillet weld that I want to grind down with higher precision than I can get with a flap disc, how well does the edge of that pad hold up?
Every now and then I get to deal with dry 5th wheel plates. In that the trailer will not allow the truck to steer, it keeps the truck going in a straight line. Lube 5th wheel and truck steers normal. I had one on Hwy 299W in the Trinity River canyon, driver had hard time making the curves. Perhaps you went up 299W to get to Happy Camp. You got good stuff!
I'm not going to say that weld is not structural because it is to a point but most of the load force is back and worth not up and down the more important part is the fitment in the hole
Oh cool I didn't know that the fifth wheel plate could wobble left and right. Come to think of it I've never looked at the kingpin of any trailer but dry van. Makes sense, just never thought about it.
I also have used cubitron abrasives at my work and we only ask for them, they are the best full stop, even tho the higher ups dont like spending that kind of money on pads, disks and grinding wheels they cut down on labour time by a big margin and they last alot longer then other brands so you dont buy them as often therefore saving money and waiting time on ordering consumables. I swear by them
I work for a small equipment rental company and we deal mostly in power generation, but pretty soon we'll be entering the earthmoving sector and i'd love to hear your reccomendations for a welder/generator to go on a service truck? We don't have a dedicated welding truck, it's a lube truck and while not ideal I'll have to do my best to make sure it's equipped for most jobs. I'm the head mechanic (one of only 3 total) and the owner of the company told me he'd like me to learn the hard-facing process for the buckets on machines we'll be getting. I'm not a certified welder, although I have some experience with flux core and MIG welding but no experience with dual shield or stick. I'd be looking for a machine that will cover all the bases, would love to learn arc gouging too. (I don't plan on doing any structural welding until i have the experience) What's the best way to go for a good all around setup without breaking the bank? Love the videos!
My choice would be a 302 air pak. You can do light gouging and it will provide all the air you will ever need. You can run a wire feed unit off of it. Good all around machine.
If most management had to choose between preventive maintenance and going blind they'd be navigating by striped cane. Cubitron and everything else 3M make is wonderful. Not cheap, but cheaper then blowing through crappy abrasives when time is money.
I have owned and been working on trailers and trucks my whole life and I would think that the tractor that has been pulling that trailer has wore out fifth wheel jaws or they are extremely out of adjustment with a lot of slop to wear out a king pin that bad on a relatively newer trailer even with a low amount of grease that was on that plate and kingpin.
Boy!!! that's real risky stringing!!! I would NEVER use use fabric straps thru a pin bush hole--- could be a burr in there that would cut that strap like butter!!! just ask I,C weld about that---- always use a shackle with a strap!!!
Hey brother, great videos, learning a lot from you. I’m watching your excavator bucket wings vid. If you love your dog please don’t have it around while you’re welding because it will look straight at the light! I’m sure you know how that feels as I do. Please point this out to your viewers because I’ve seen this on many different channels, please help all the pets out there! Keep up the great work & videos:)
Hi Senioro Greg, Yours is an prime example of leave them wanting. The 60 min plus vid's are seldom worth staying the course. I looked at your weld around the new plate and on the "right" side, it looked like the weld just rolled up against the plate edge. I know your work better than to think that but why did it look like that? I tried some 3m Cubitron sanding discs but did not see a big plus over the good quality alum oxide discs I buy. I haven't tried the grinding discs because I haven't had any welding goin on. I could see what you did in real time and it is clear they cut like a hungry bear..... Threeeess to Ya Laddie. Ye Ole Caterpillar Cowboy

I grabbed som e elcheapo ceramic disc before I spent the 3M money, holy shit they cut and last longer than aluminum oxide discs. I know where I can grab some from…..

The Ol' Grease worm does lots of damage , but just think of all the time those operators saved by not greasing ...............

Love the decal on the truck You Tube certified mechanic, Great job perfect!!!
*On Fire Welding* Bravo well done, always a pleasure to watch, thank-you sir for taking the time to bring us along. GOD Bless.

Good job sir. You stay busier than most you tube welder/machinists. I love. you channel
I have a friend who has a construction and demolition company. He changes the colors of the grease he uses so he can tell if people are greasing or not greasing the equipment.
Another great job, thank you for sharing and your explanation are very good , another great video who i watch when i start my day 👍👍👍👍

cheers, Paul
Greg the Cubitron cutting/grinding wheel is unique I totally agree after trying it
I've tried them 36 grid on a 7" inch grinder.....
They can remove a lot of material.....fast..
I have not done much welding but i see what you do and how thorough you do your jobs, always impressed by your work ethic and keep the videos coming
I was going to buy a welder but watching On Fire Welding videos is so much cheaper, and the welds are better too.
Brings back memories , I’ve done some many of those things back when I started. But with a torch and and old hobart welder with jet rods!! Man how things have changed for the better. Great job!
Thank You from Temecula
Always Bad A.. and straight to the point!!!!
Love the show . You do great work and don't over talk. 29 years as heavy equipment mech..I know
Always amazed at all different repairs you do. Keep up great work & videos🤘🤘🤘
Love that Earl Schieb 'FactoBake' paint finish........
Wtf you think he's gonna do most people wouldn't even paint it at all. It's a repair one your jealous of
You’re in Fresno! I didn’t know that.
Thanks for another very good video and discussion.
Have swapped out bolt in adapters on a couple of those in the UK. Nice and simple job for a change better than beating bearing off for hrs.

I work at a Cat dealership and unless we need to dig something out with a hard stone we majnly use the cubitron sanding disks for everything. They are awesome!!
Those are the best for grinding on flat surfaces. It took a second for me to transition but once I did I never looked back
They need to "UNHOOK" the trailer and grease the plate and all pins... But that is just more work for you if they don't... Good work! Ron...
I like your channel, i have learned allot from your welding videos
Beautiful work !!
Ive always thought of goiging as a weapon of mass destruction, but seeing you cut that kingpin insert out has changed my opinion. Nice work.
This came apart a lot easier than that stump grinding thing-a-jig in the last video.
Nice work, Greg! Thanks for showing such a variety of repairs on your channel! I think I’m gonna look into those Cubitron discs.
You can buy a lot of grease for what it would cost to repair stuff. People just don't want to take the time to grease stuff. I see it all the time
Thanks for the video!
Trabalho muito eficiente e rápido. Parabéns do velho professor do Brasil.
Great job!
Always a great job people that don't grease shit to keep you in business.😊
Wow ,that cubitron grinding disc is amazing
Great work!!! Not trying to publicly blast...just asking a question to learn. Do the craters left behind by the carbon arc gouging process weaken the base plate?
No, there were filled In with the new weld. I should have cleaned them out a little first though.
I was going to buy a welder but watching On Fire Welding videos is so much cheaper, and the welds are better too.
Great job on the replacement love the vids.
One thing you do not grease the king pin , the jaws are out of adjustment on the 5h wheel. Many many fith wheels today use a Teflon or wear plate no grease whatsoever. Only place that gets greased is the side pins and jaw mechanism.

Yep. They were trashed. Customer installed brand new ones. Hopefully correctly.
@OFW they need to check and maintain adjustments, the driver who drove that trailer should have been screaming something was wrong just a small amount out creates a noticeable clunk also ruins the truck.
Great work young man!
Everybody knows part aryweigh more cheaper than greased right lol but it keeps you in business love your videos be safe and have a great day Sam
I say, you and Issac at @ICWeld are masters with at arc gouging!
I used to refurbish those on the trailers.
Just amazes me...the lack of simple maintenance and a little bit of TLC...if they made the damn operators go out there with you on repairs (and act as your handimen and gofers)...I bet they would take more pride in just pointing the equipment down the road...they aren't operators...they are just drivers
Ah well...job security for a good welder! You need a sticker that says "I'm here because you broke something!"
Keep em coming!!!!
Maybe make the company's operators to pay a percentage of these repairs and I bet they will start lubricate frequently
I have gotten to the point, if I see a no grease situation....
.I have no respect for the owner and do not want to do the job....
.cheers my friend, Paul in Florida,
I'm willing to bet that Greg smiles all the way to the bank each time one of his customers, who are lax on maintenance, calls him.
Christ the undercut all the way around the original weld is pretty insane.
AirArc is just awsome I watched a Russian dude cut a massive steel roller his rods must have been 10 ft long and he spend all day cutting this thing into giant chunks lol
I've been binge watching now for two days On Fire Weilding is at the Top of his game one of the very best I've seen on YT

I swear by them
Nice job.
More to the point: Amazing what a compleat & utter lack of even a little grease can do....
Why do they preheat metal before welding sometimes ??
It helps relax the metal from welding stress.
Nice fix
Like watching your vlogs..maybe just interesting

that pad really did rip through that weld, would have liked to have seen the pad after as well.
Wat was the issue the king pin was wore down due to lubrication ?
lube and the locking jaws not being adjusted correctly.
Bro "TH-cam Certified Mechanic" is fk'ng hilarious!! Right on the back of the truck! Love it, thx for posting more vids my friend...
Bon Boulot ❤😂
Get rid of that sling before it gets rid of your toes!
Hey good job man take care
1:46, lol, Freudian slip? check all the cracks or check all the welds for cracks.
You made that look easy.
I have owned and been working on trailers and trucks my whole life and I would think that the tractor that has been pulling that trailer has wore out fifth wheel jaws or they are extremely out of adjustment with a lot of slop to wear out a king pin that bad on a relatively newer trailer even with a low amount of grease that was on that plate and kingpin.
what temperature are you preheating to?
300f ish
Wow, i was imagining you having to do that upside down on a trailer. Much easier your way!
Coffees on guys!! Got to grease it!! Cheers!;-)!!
Thank you for using a strap to hold up the plate, so you can’t arc,out the crane cable, seen people over the years not doing it right .
Hopefully one day the customer will respect you enough to clean the product before they give you the job.!!!
I don't think paint would be an issue because it wasn't greased very often if at all.
Maybe a driver's retirement fund should get a bonus when his machine demonstrates proper maintenance.
If that was removing all of the dirt, so you could see the cracks. If you removed some of the dirt, you could maybe think about the cracks?
Boy!!! that's real risky stringing!!! I would NEVER use use fabric straps thru a pin bush hole--- could be a burr in there that would cut that strap like butter!!! just ask I,C weld about that---- always use a shackle with a strap!!!
I think I'm correct welding king pin becomes a liability so a certified welder must be used
Weird how a lack of maintenance will cause something to wear out prematurely 😅
Hey brother, great videos, learning a lot from you. I’m watching your excavator bucket wings vid.

Perfect
What type of trailer was that?
Bottom dump. For gravel
Thanks for the reply...and the videos!
It wont hurt if the strap breaks and it hits you? Nice to know that. lol
That’s quite a disc - really hogged off the material 👍🏻
I replaced a couple of them but I had to cut the whole plate off to get to the pins

Grease and oil are both cheap, compared to replacement parts. It's your choice
When will people learn that you can buy a lot of grease for the cost of a part.
I grabbed som e elcheapo ceramic disc before I spent the 3M money, holy shit they cut and last longer than aluminum oxide discs. I know where I can grab some from…..
For sale vintage grease zerks. never used.
its strange they dont have support on the lower side of that pin...
What is the actual name for that part?
King pin
@@OFW I was told a long time ago that it is not the king pin, those are up on the front axle. No worries, I call it the fifth wheel kink pin lol.
This'll be good :)
