First time I did that on the floor is when I discovered that concrete will basically explode when you hold a torch on it. Lol!
I also found that out the hard way lol 😂
You guys are the real mvps for putting your mistakes out there so others don’t make it.
Lmfao, yeppppp. Don’t heat up concrete or rocks!
And it's always fun until you think you're awesome after doing a few,and don't get one seated down in time because butterfingers 😆
I did that once...pop...Burning urethane out of a door glass channel...oops...vice job from then on...🤪
"don't mind the messy bench" Man if the bench ain't messy then you ain't workin
Boring

This is an old school journeyman. He actually repairs things we new technicians have only known to replace.
Old school master
The problem now is where to get just the gear and not the whole flywheel? Suppliers follow what technicians want. Full parts are faster(easier) to change than actually fixing what is broken. All this knowledge is aging out and not being passed down.
True
@@leofortey7561 you are right. Been told plenty of times “ just get a new car “. Sheesh !
@@leofortey7561 I am a car enthusiast and if I needed a new starter ring gear I’d just get a new flywheel, by new I mean from the junkyard but I’m not gonna bring an air hammer to the junkyard, plus it’s probably less than a $20 difference between a flywheel assembly rather than just the ring gear
Great that your old man is passing all his knowledge to you and to us. God Bless you both 🙏🏻
Have to be honest had no clue the ring was separate, never had to replace one besides a worn plate...very cool
Another protip: You don't have to barely heat the new ring, if you also put the plate in a fridge or freezer just to where it's slightly cold to the touch. Cooling the plate gives you a couple thousandths of shrinkage, and slightly heating the ring gives you a couple thousandths of expansion. That thing will pop right on there in about half the time and effort, with less extreme temps to either component. So no risk of warpage or metal hardening. :)
@@strikeforcek9149 definitely! Route I prefer to take on expansion as much as possible. Thanks you the tip
@@strikeforcek9149 I was a jet engine mechanic for ten years and when we would tear down the engines for inspection, there were a few bearings and seals that we would would put the bearing in the freezer for a bit and then next to it we had a heat cabinet which was similar to an oven that we would put the race in to heat it up then put them together. It amazed me back 35 years ago that just how much of a difference a little heat and cool temps can actually change a chunk of hardened steel like that in just a short amount of time. Makes me wish I payed better attention in science class, lol
@@1982MCI lol. Yep, it's insane just how little it takes to change something drastically lol. Definitely makes me wish I would've paid attention even more too lol.
Same concept applies to numerous mechanical assemblies. Warm connecting rods and cool the piston pins, put sleeves in freezer a while before installing in engine block, etc. The wonders of science.
Bruh did you see pops face proud as hell of his son recording him this is the kind of people we should be following learning from just saying
You’re right. You can learn a lot from the older generation. 👍

@S_vH Facts i bet if Tik tok would start a challenge today of be unique be yourself invent something be a pioneer,you would see maybe 100 kids and the rest would be lost sheep's lol
@S_vH you are 100% correct
You’re right but why the hell doesn’t he put the jack on a stand so he doesn’t have to kneel down for six passes?
My uncle ran a shop for about 40 years and had a little oven in the corner that I always thought was junk until I saw him pull a pinion bearing out of it once. I was fascinated by the concept as a kid.
And popcorn.
I had a toaster oven set to 180 degrees for bearings. Worked like a champ.
That's old school knowledge and years of experience...bless that man!!
Thats called annealing and good luck with your softened non case hardened ring gear
@@gitar1hero1qaz ...if it wasnt safe to do in any capacity my dad wouldnt have done it for years on aircraft. With procedures APPROVED BY THE FAA. And before you say "they were bought off", no. These are the people that will fuck with you harder than the IRS if you miss a single thing, no matter how small. So if the FAA approves, im sure its fine. Besides, he specifically said "not red hot". Its just using physics and thermal expansion / compression to achieve a good fit. Shit ive known about for *years*. Note: if it wasnt tried and true, it wouldnt have been passed down the generations of mechanics and shop hands.
I did a similar thing in college. My old school teacher froze wrist pins for con rods and slipped them in
I was a new guy at a 120 year old company and watched an old pipe fitter do something similar. They could cut their own large gears.
@@cq4538r depending on the metal this procedure can be done with even heating (not just with a torch). The thing is the metal used in aircrafts is specifically sorted for specific procedures. Just cause you can do a procedure with some alloys does not mean you can do it with all of the alloys.
Thank you for mentioning his knees, I felt that floor as soon as he knelt down.
I always kneel on my opposite foot. Am I the only one?
I use motorcycle pants with knee pads built in. they are also more resistant to welding than jeans.
He need a pad on that floor for his knees
Your old man is a champ,, don't let anyone tell ya different .
You learn something new every day. I always assumed that the teeth were part of the flywheel 🤯
Your Dad knows from many years of doin it. You’re fortunate to have had someone like him to teach you all the tricks to help you get the job done, and done right. 👍🏻
I would much rather pay tuition to a man like your Dad rather than college. I was fortunate enough to learn from someone like him and I can't begin to tell you how grateful I am to this day. The lessons stuck with you for life.
It's funny when I went to a technical school for automotive the teacher was an old man instead of teaching us about how to work on cars this man was showing us how to rebuild water pumps power steering pumps how to do alignments using string and magnets how to rebuild carburators he really didn't teach us nothing about what really goes on in a real shop but I'll tell you one thing when I worked on one car I remember the parts store didn't have the part needed and noone had power steering pump for that car and the knowledge my teacher reached me came in handy because I remembered how to rebuild them and ended up rebuilding his pump and it worked perfectly fine after I rebuilt it and it stopped the major leak it had my manager even told customer that we couldn't find part anywhere and told him that I rebuilt it for him the customer check to see if it was leaking or not when he seen it wasn't leaking anymore he gave me a hundred dollar tip
I flipped the ring gear around on Datsun once, to present fresh roots faces to the starter pinion. A brass drift took it off the flywheel. To reinstall I heated the ring in ghe oven + chilled yhe flywheel in the freezer. Easy peasy.
I noticed the back of the teeth have a squared edge compared to the front's edges are rounded to assist smooth engaging of the starter. Figured it'd cause trouble starting on back to front.
Good job , Dads are great , most of them have forgotten more than we know . Love your Dad . Respect the knowledge .
Look around the shop for places where you and your dad have to kneel, crouch, lean out etc. Many of them may be easy fixes (taller work stand). Those fixes will make life easier and less painful for pop AND will help keep you and other pups from developing similar knee, back, hip, etc. problems over time.
I'm using the oven and the freezer method. Cool down the flywheel, heat up the ring gear But yours is way easier and faster. Thanks!
The freezer and oven gives a much more even heat. Freezer is around 0°, oven at 500° produces quite a difference in size.
The oven in the freezer technique works for so many things And with the oven freezer technique You have less chance of burning the s*** out of the gear some people torch it too much in one spot and distort the gear
This dude's shop does higher volume than hobby mechanics like most of us. I myself used the oven + freezer too, but it was a weekend project for me & the wife, not on a customer's dime.
If I were you Id stick to the oven technique. The blowtorch has a much higher temperature plus you have actual control over the temperature. You might loose some of the steels properties from heat treatment if you reheat it in an uncontrolled manner.
@@HiroNguy well if that's thé case, then there is a lot of magnetic systèmes that would heat a lot faster and with near to 0 risk of deformation. And they're not that expansive. :)
Damn, I thought for sure that the teeth were machined into the flywheel
Same here
Hey no worries! I love mechanical items of all kinds, guns, cars, tools, doodads of any kind make me smile, for the longest time I thought the same! And you aren't wrong tho, some gear sets ARE machined as is. But when you think about it it makes sense for a vehicle, I mean you use it almost every day all the time and parts WILL be replaced or worn on it after all, i suppose it's easier to machine a ring with teeth and it makes it much cheaper when there is very little material. Plus if you have a problem with one you can slide it off and replace the teeth themselves (which when I think about it its genius) because they're the one part of a gear actually being exposed to wear and tear, so why throw out the whole thing when you can replace just the ring? This is why I love things like this. Each day you learn something knew! Even if it's not complicated, its neat. It's even cooler in my opinion when the solution to things like this is the simple answer used in a clever way.
Me too, I always thought it was a single part/piece.
I didn't
same here
He does excellent work,we can tell your proud of him,you guys are a blessing for each other,it's awesome
Your old man is one kick azz dude!!!! Total Craftsman, you're lucky to have a dad like that.
Make sure you tell your dad you love him as much as you can… Your mom as well; I’ve lost both of my parents and I’d give both my arms and legs to hug and kiss them one more time!
I also lost my parents to improperly installed ring gears...
@kafel Bellic I fail to see how people can wish karma on someone for typing something funny. Smh.
@kafel Bellic I'm sure karma doesn't appreciate you wishing bad on people
@kafel Bellic coming from someone who lost both parents as a teenager I appreciate both the original comment(though how would he "hug" them with no limbs?) And the baddest ogre's humorous input relating the loss of parents to this post. Stop wishing bad on people with good intent
@@paulstallings6804 thank you, both of my are actually gone as well. Luckily they both had a sense of humor.😁
There's some videos online you can watch on how they used to fit "tires" (heavy steel rings) onto steam locomotive wheels, they used to do this so if they got a flat spot instead of replacing the entire axle assembly they just remove the "tire" same method as this but to achieve quick and even heat they would soak the tire in diesel and light it on fire and within seconds it was expanded enough to set on the wheel
Wow on a locomotive!? That would be awesome to watch I'm going to go check it out right now
Cool
During the later part of steam, they used a ring of fire to warm the tire. Wagon tread rings are mounted the same way, with the difference being that the metal is red hot, and the entire wheel is dipped in water to cool the metal and seat it properly. The compression of the ring is what keeps the assembly together.
Very cool, and nice torch work. Sounds like thermal expansion. The increase in temperature causes the molecules to expand while decreasing temps will cause shrinkage. There are some exceptions to this rule in some materials. Water for example stops contracting and starts to expand as its cooled to freezing, however only for a limited ranged before the material starts contracting again.
Your Dad is the man!
Did this using a bbq grill. Half of the ring gear teeth where worn, so I just flipped it over. Worked flawlessly ever since.
I had a Chevy flywheel that I put on backwards cause of work teeth. Can't do that on these newer cars
On my car I was able to reverse flywheel, automatic trans, the flywheel was neutral balance
At a low heat it really is a better way, or an oven. With a torch you risk getting it above 500F and ruining the heat treatment of the gear teeth.
“Hey, the mechanics have figured out how to reuse these gear rings by flipping them over. Make a note to redesign them so they’re half as thick, because f those guys.” - engineers.
I just flipped starter ring over on my brother's father in laws truck engine. Had to weld it on to flywheel. He bought truck new and gear came off flywheel at less than 30k, Chevy dealer welded it on first time. On an old S 15 4x4 small truck.
My dad taught me the same thing, I miss him.
I'm glad you called him dad and not the old man 👍
My kid calls me pops, but that's beside the point. I used a similar process to change a ring gear on a limited slip carrier in a car, once. Carrier was placed on its bearing standing so the gear was facing down, bolts already removed. Used the torch to heat the ring gear, and it fell off. Turned the carrier over to the other end, standing in its bearing. Placed the replacement gear so when it fell, it would line up with the bolt holes. Heated it up, and waited until it fell onto its seat. Did a quick alignment with a spud, and made sure it was totally seated on its own. Then, the bolts were torqued down, much like a wheel bolt pattern. Never had a problem with that method, and never overheated the ring to lose the temper. I will say that I'd did take a few more than six passes, though. Those things are THICK.
Mine as well. He's always fabricating something. His ingenuity blows me away.
Dad is an absolute ripper! ❤
Nobody asked for these KZhead stories but i tend to watch these more idk why there all just interesting
KZhead knows all about you and what you would like to watch its very smart algorithm.
All knowledge is good
It’s a lot easier to just scroll through the short to the point videos than having to search for what you wanna watch
Theyr like Tiktoks but not shit
Get dad a taller stand and wouldn’t have to get down on his knees. 🙄
Or atleast knee pads
@@willydmankal my thoughts exactly!
Every dad i know who does manual labor says the same things. "Knee pads and gloves are for pussies" lol
When he knelt and tussled with gravity for a mini second there, I cringed because...damn...been there 😣
This shit sneaks up on you. I'm only 28 but my knees are bad due to the army. I look like this dude's dad when I kneel
So glad ole Skool knowledge is being passed down. Your Dad is a treasure. Learn all you can.
Professional all the way. The way he got the gear off with smooth movement. 😊
Thats awesome I believe for every 100⁰ you expand steel you get 0.001"
1 inch of steel expands ~.001” per 100°F. Yep. That’s essentially the basic rule.
7 micro inches per degree F, that's the coefficient of expansion for steel. This is simply a coefficient for plain steel, so a shaft. When you have a thin walled sleeve/gear it will grow differently.
@@patrickirish9427 im not a machinist never learned the proper coefficients of what metals expand at lol
Interesting fact. Thanks 👍
@@patrickirish9427 Your understanding is flawed. The coefficient of thermal expansion is effectively identical for all grades of steel for this purpose. It doesn't matter if it's a solid disc or a ring the calculation is the same. Go look up the math and I can walk you through it.
You and your Dad are National Treasures.. The way you talk about him is admirable. His skills are perfected. You will carry his sentiment forward. It’s not what you do, it’s how well you do what you do. Wish I needed a clutch replaced.
These "older" guys are a treasure. You can't buy the kind of experience that following this guy around would provide .
I was in the transmission business for years. I learned something weird. The physics of a engine always stopped in one of three positions when you shut the engine off!! That means that everytime I started the engine the Bendix would hit one of three spots every time. Which led to wear on the ring gear in those spots!!!! Your father is spot on!! That's how I changed out Ring gears on manual transmission flywheels👍😎
His attention to detail is a rarity nowadays! I love that he spins the ting gear to ensure a uniform fit . That's genius!
Did this many years ago and you have to make sure the ring gear is on correctly or it means starting again from scratch if it doesn’t fit properly ,this chap got it spot on
You don't have to spin for it to cool or get a uniform fit
“After a couple hot seconds” heh literally
That's what she said... unfortunately :/
@@tmovchan4021 🥲
I was looking for this comment
@@pumawombatDOG2 you found it
Thank you 😁
I’ve always stuck the fly wheel in the freezer for 20 minutes and the ring gear in the oven @175 for 20 minutes🤨and never had any issues🤷 😎✌️🇺🇸💪💪
Thanks DAD 👍👍💯🤟✌️.. Your Dad taught me more in 25 sec then my Biological GOOF and STEP GOOF FATHERS EVER DID 👍💯..THANK YOU ,AND THANK YOUR DAD TOO.
Your old man is an awesome man may God give him the strength to always keep doing what he likes
Nice 20 years never saw it down good job pop miss you freddie everyday
Dad's a great instructor!
Hey man, love the videos. Not sure if you have ever tried it or not but if you have an old oven you can put a flywheel in there for 5-10 mins the old ring will fall off. Throw the new ring gear in the oven for a few mins and it will drop right on
Why do that when you can use fire? 😳🔥😅
@@dannygurney5130 Oxyacetylene is expensive
@@explosivemallard8038 Yes it is. Yes it is. But, it is explosive fun.
@@explosivemallard8038 the rig might be, but filling bottles is cheap.
You jus said it, 5-10 mins.... Using the air hammer is faster. And it looks like a shop use paying for gas is cheaper in the long run 😉 doing other jobs and such...
Been a mechanic all my life and never knew this was a thing 🤔
Me either
I'm a machinist. We have tricks for EVERYTHING!! Probably have heard of this one. If you cant get a bearing off a shaft throw it in the freezer.
I'm a industrial mechanic. I don't even work on cars :c

So glad u have alot of respect for ur old man..(knees) u were raised right..wish u n ur pops n rest of ur family nothing but the best..stay safe and get ur old man a pillow to kneel on lol
I was really impressed that you were working with your dad.
That's wild, I didn't know those gears were just a static interference fit.
You forgot to mention,He's using a Rose-Bud head on his torch..(for those that are wondering)
We did this as well when I was a kid and dad was teaching me. I've overhauled starters instead of getting a rebuilt one. We did it ourselves. Alternators, same story. Bored motors or sleeved cylinders and rebuilt motors from start to finish. No crate motors back then.
Watched Dad do this circa 1972 in the garage. It was fascinating to watch.
Your Dad is an awesome Man a wonderful generation of American.
With all do respect. His dad is probably a good man. He looks like my dad's age. However, if you think boomers as a whole are a wonderful generation, you are completely oblivious to reality. Our grandparents were the Great generation, 80yo+. Boomers are nothing but greedy, selfish out of touch NPCs. Our grandparents left this country in pristine condition and over the last 50 years boomers have destroyed it. Radicalizing the schools, draining the social safety nets. Not fixing the infrastructure, offshoring businesses, outsourcing jobs. Selling off great neighborhoods to the highest bidders from China, or renting the house to people that just trash the neighborhood. Enjoying their retirement with their two houses, boats, RVs. While kids with masters degrees who they told to go to school have no jobs, because boomers sent them overseas. They say millennials are the worst generation, but I disagree. Millennials were screwed over by boomers. Boomers will go down as the worst generation in American history. All this chaos and division is happening in this country on the boomers watch, and they're clueless on how to fix it. They created it by radicalizing the youth and with their social experiments. Boomers are some of the dumbest people I've ever run into, and don't even have a grasp on basic history or society. They were too busy having fun in the 60's, 70's, 80's and 90's, to actually pay attention and know what's going on, and now in their old age the raging narcissists are trying to leave a legacy that doesn't fit their reputation, and in the process leaving a trail of destruction. I'm gen x for the boomers reading. Try and call me a dumb millennial now. Edit: I just noticed that you're not from America. So I understand the confusion. The generation you're thinking of was born before the 1950s. Boomers as a group are actually quite useless, and many of them don't have any of the skills this man does. Gen x (my generation) and millennials are even worse in that regard, but that's because boomers were their parents.
Love see all the machine shop processes.
That hit home...."Dad does about 6 passes" RIP Dad....Keep doing what you're doing Sir - Mad Respect
Can't even find just the ring gear for a lot of modern vehicles unfortunately. Gotta replace the whole flywheel. I love how the old-school cars have every part you could need.
You're Ole man is a GOAT👌👌BIG respect !!
Saw my old man do that in mid 60's. We've probably done 40 or 50 in 50 years.
"Please don't mind the messy bench" 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
God bless him, props for the steady hands.
Your dad’s approach is old-school and masterful. Suspend it hit it, drop it and spin it.
You can tell his dad has done this 99373393876365 times. Very good at what he does
I had a 74 Chevy truck with a stick on the floor 350 motor did some work on it years ago and that fkr sounded decent my old coworker and I left last ones from a auto parts store he burnt rubber leaving so he wanted to see what I am about so I let her rip but afterwards the ring gear slipped right off I learned from there at that point on heat is the enemy lol 😂 thank for the video
Ok... Doesnt have anything to do with heating a ring gear up to slip it on a flywheel though. Once it cools its as tight as it was before.
@@mikeznel6048 😂q
I helped some machinist at work do this once. The old FFGs had two Detroit 8v71s that had a coupled crankshaft so the engines were linked together. The generator set consisted of the two engines and a 480volt generator head. There was one genset on the port side and one on the starboard side. The ring gear was probably 20 inches in diameter. The machinist brought it over because we always had a torch hooked up and I set up another torch so we could both heat 180 degrees evenly. We pulled the old ring gear off and heated up the new gear then the machinist installed it. He went back to his shop and returned right back and told me he installed it backwards. Interesting project, they cut a section of the Hull out just big enough to pull the engines out. They have to install a cofferdam because 3 feet or is below the water. The remove, rebuild, reinstall and test one side then flip the ship around and do the other side.
Never Seen it Removed Like That ! Works for Me ! Your Dad Does Nice Work !
In the old days we would just flipped the old one over
I'm in the old days, now.I have not once bought a new one for a client yet
But I bet y'all billed the clients for new gears 🤔💭$$$$
@@jimwednt1229 nah, just a small fee for the work done.
@@Kekeslicious Sure.
Same here. Flip it and be done. ✔
"please dont mind the messy bench" I can only wish my dad's benches were that clean
Worked at a farm tractor shop and I think we set the ring gear on the flywheel, ran the rosebud around until the ring gear dropped into place. Same result, just didn't have to handle the hot ring gear.
We always stuck our ring gear in the oven when mom was'nt looking...
Try them with cream cheese frosting! They're delicious!

Your oldman is a legend. You better be taking notes friend.
Serious note ... I wish he was my dad
His knees hurt because he’s been holding the weight of your families world and business on his shoulders. You ever though of that. Read this to the Man called “Old Man” and see what he says. If he smiles then says it’s something else then I was right. If he immediately says true he does it out of pure heart, soul (plus all above) and possibly a tad bit tired.
Man, now that I think about it, that's probably where the term "hot second" comes from!
YOUR LEARNING FROM THE VERY BEST ! BE GRATEFUL !
I was told you learn something new every day... *and today I definitely did*
so true. I just learned and I've been turning wrenches over 30 years.
I affectionately call my dad “old man” as well ☺️
Right, "old man" or "The old man". But "my old man" is literally a term used by women for their husbands. Especially used in the biker community.
"if the bench ain't messy, it's not being used." That's what I always say. 👋🤪👍💯
It's nice to see an old school mechanic. I couldn't tell you how many of those I replaced in my years.

Great tutorial. Couldn't have done it better.
We always hated the ring first to knock off then heat to install. I did one my first time after helping my Pops when I was 12 to 14, but at 22 or so I did this repair for my Grandpops on a 1940s or 50s model Farmall H tractor, single dual front wheel setup, that spun on the chain hoist and flipped breaking the exhaust manifold, D'OH!!!!!!!!!! Live and learn, and no one got HURT, almost but not quite. It was a success in the end, that was 20(+) years ago, GOOD TIMES!!!
"Dont mind the messy bench" Me: its clean even when you're not working on it?!
The narration on this is discovery channel worthy! Your Dad, simply amazing!
My favorite kind of videos!
God bless your dad and his knees I got the same problem
I never knew that gear was replaceable. Thanks
Perfect job. Experience shows.
It's nice to have all the proper tools required to do all your automotive needs, especially if their specialty tools to make job easier, saves a ton of money on labor at a shop
Man every time I watch one of your shorts I think how lucky any man is to have or have had a great father in there life. ❤ 💪🏽
Love this channel. Very informative for us average guys
It's amazing how changing the ring gear on a flywheel is so similar to what a wheelwright has done for the last hundreds of years
Amazing the power of knowledge, fire and physics!!!! Great Job Guys!!!
I’m 40 and seen the knees to concrete formula and just naturally winced in pain. As an former baseball catcher, I know how hard it is to get back up.
Very interesting. I would've liked to have seen an up close look at the tool on the end of the air hammer. Never seen one of those.
Perfectly done!
You can also flip it a 180°and wear out the other side.
In many General Motors manuals it instructed you to put chalk on the flywheel area where the ringleader goes to improve the gripping power.
Old school skilled mechanic. Sort of man you want working on your car or rebuilding your engine.
I hope that old man lives to be 130 years old cause men like him are a dying breed.knowledge with experience
