John Deere sells junk and have gone so far now as to add serialized chips on every component to prevent owners from servicing their property. Ford Tractors are still around too, and so plentiful resale isn’t that high. In my area I saw 3 a couple weeks ago for $1200 and a giant one with cab for $3500. Ford runs, flat runs, even though the closest dealership by far is John Deere there are more Kubotas,IH’s, Case, and by far Fords.
I was a kid when we brought a brand new 4020 in 1966. It was the pride of the farm. Good to see the inside of an engine I spent so many hours operating
My wife’s family has a 1957 John Deere 420 that has been on the farm since the day it left the dealer when it was brand new. I absolutely love that tractor. I miss raking hay with it, ran it for several summers 5 or so years ago and loved every minute of it.
The joy I get from watching this type of informative content can't be described. I'm only 22 and wish people around my age could relate to wanting to take care of their possessions and be able to keep them working forever by repairing them. Great videos as always.
Hey man, 29 here. Not too common in our generation, but we're out there. Just got done doing a 200k rebuild on my 04 Ford :) Love keeping things working as long as possible
The biggest problem with buying a brand spanking new machine, whether it be a car, truck or tractor, is that the cost and downtime to get it repaired is more expensive than buying another new machine. And thats not the customers fault because manufacturers purposely do not build their products to last the test of time.
Hey man I’m 19 and feeling the same way, it’s sad to see the way things are going. Everything is throwaway now when it should be rebuilt and ready to go.
I have an old laptop with a windows 7 sticker on it, thats easily 10 years old with the original battery in it and running windows 10. Once microsoft cuts support for windows 10 I'm off to Linux land. I seriously don't get why people must buy buy buy and consume. The only money I have had to spend on it is a new power cord and an SSD so it doesnt take an eternity to boot. Saving money and the planet used to be the NORM before our parents, it is a shame we allowed corporate profiteering to take hold so repair is difficult or impossible.
A lot of engine machine shops are seeing more older farm engines coming through because it's cheaper to get older equipment up and running like new than spend half a million bucks on a new tractor that will break down after a year of hard farming.
I was never a farmer but I've always loved vintage tractors for some reason. It's especially great seeing a decades old machine still doing useful work.
My first job was working on a vegetable farm and they had a bunch of old Deeres that run like tanks...4440, 4240, 4020, 4040, 2520gas, 8450, 8760, etc. Its amazing these engines are over 60yrs old! Awesome channel guys!
I like that you tell the horsepower of each engine. Most people outside of farming hear 100 horsepower and think it’s weak but they don’t understand the basics. 100 horse tractor is a large tractor and can out pull any of these hot rodded diesel light duty trucks with fancy wheels and do it from daylight to dark every day of the year. Thanks for giving away your knowledge to teach and entertain us
There is also a major difference between a non-aspirated diesel that runs slow versus a turbodiesel that is pushed to its absolute limits regularly. The slow engine will last far longer than the modern engine due to less wear and tear. And no fancy gimmicks and electronics helps a lot.
@@emilschw8924 Probably wrong in fact, but keep making wild conjecture you will be right someday. I shouldn't have to explain but first learn how a constant pressure engine works.
Everyone seems to misunderstand what I was saying with my original comment. I was thanking them for telling the horsepower number because it lets people like me and others that have tractors know what size tractor the engine is from. A 30 horse kubota and a 115 horse kubota are two vastly different sized tractors. Also when you buy them they are rated with engine horsepower and pto horsepower which are both needed to decide if they can reliably handle the equipment you plan to drag behind them. Try dragging a 15’ batwing through 4’ ironweed in fifth gear on a 60 horse tractor and tell how fast you overheat. Hope this clears up all of the confusion
The reason you see them so commonly isn't because of the reliability of them, its due to not wanting something that if you don't pay subscription fees for some software it becomes a brick.
@@Xaeron87 John Deere is one of the reasons the right to repair movement got so much traction in the agricultural sector. Other Brands are quick on following up, but JD is and was for a very long time one of the worst brands to have to deal with when it comes to repairs and support. They are on an Apple level, just in the tractor industry.
That opening couple sentences are pure gold. I worked in a gear shop for ten years, ten tears ago. Any spare moment in November and December were spent dragging cores out and rebuilding transfer cases and manual transmissions for the winter feeding season. Those old ranchers seem to forget the problems they had in March and April over the summer season.
Given all the anti-repair crap John Deere pulls on their modern hardware (stuff designed to force you to pay a fortune at the John Deere dealer to get your stuff fixed) I can see why people would want to keep their older Deere units (that don't have all that crap) running and working.
I know quite a few equipment handlers have started digging old iron out for that very reason. It’s becoming cheaper to go through and rebuild them vs paying the price of the new equipment that you CAN’T fix!
@@Nudnik1 True. However a lot of Deere parts are actually another manufacturers parts that have had all part numbers removed. When a card fails, Deere can't get it anymore and you can't find out who made it...... Good luck.
I have a 1971, 4020. It starts and runs so nice. It is quiet also. I was interesting seeing the different year heads. The gas head was cool also, a nice closed chamber but wow were the valves shrouded. Thanks guys. PS. I like Orange Tractors too. I live not to far from where those were made in WI. 😇
When I worked for the City of Santa Ana we had a few JD back Hoes in several departments ! All of the engines had Wet liners that I liked ! Thanks for sharing !
These parts are at the machine shop because they work. The owners are keeping them running because they work. Part of owning something is taking care of it and the machine shop is part of that process. We could dream that we never have to maintain our equipment but with that thought process, the machine usually dies and ends up dead in a bunch of weeds or scrapyard.
I was a former tech at a Deere dealership in McCook, NE. When I started in 1997 there were many Waterloo 404s, 466s, some 7.6L and 8.1L used for irrigation engines. We also had many Dubuque 4045s and 6068s as well. As diesel fuel became more expensive, the diesel engines were phased out in favor of electric well motors. As I recall, the Bosch-style injector was a KDL, and later the KDEL. I called the KDEL the 'easy' injector because it was much easier to tighten down without having to work around the big cast head on the KDL injector.
The way your dad talks is very pleasurable to listen to. He should be an audio book reader! I’ll listen to Moby Dick, from beginning to end, if your father does the narration!
Yes sir, it sure is a pleasure to watch your engine remanufacturing videos. I had the pleasure of attending an automotive engine remanufacturing course at our local community college back in the early eighties, and we covered all of the steps in the process (we had all of the equipment to do a thorough job and of course all of the manufacturing specs). Of course, the equipment you have is needed to be able to do accurate and time effective work nowadays. Your level of craftsmanship and your attitude of making a rebuilt unit better than new is refreshing and I am sure that there are many shops that have that attitude (one shop I use from time to time the gentleman who runs it refers to "restoring a cylinder head" for instance).🥸👍
I have an auto shop in north western PA. I have an auto shop and jobs go in spurts. I'll do 10 oil changes one week and it will be a month before I see another. I've done like 100 gm 2.4 ecotec timing chains. 3 in 1 week for a car lot up the road. Got 2nd one done that week and called to tell them it's done. He was like can ya take a look at a silver Malibu. I was like what's wrong with it I thought I just fixed that one Monday? Nope it's another one same color. 3rd one that week. I am a 1 man operation. Just me doing everything
Doubt life will have a reason to take me out that way again, but man, what a beautiful part of the country. Speaking of old things they don't make like they used to, there's a gorgeous cage elevator a hop skip and a jump from you I'm sure in the National Transit Building. I suppose Blue Streak also qualifies for that category, but I'd sooner trust an elevator that hasn't operated in like 75 years than that rickety contraption.
Love your videos I can relate to your work .I was A farmer my whole life done most of my repairs but never got into your type of work.In Australia my tractors were mainly Fiat can honestly say I never had a head off or rebuild done.Back then they built things to last.I won’t mention names of my last machines but we’re problems .Cheers love your videos from Bundaberg Australia
Great video, thanks, love to hear the cleaning guy explained stuff, plus I like that he is an AC guy, I have a ‘49 WD that I built a WD45 Clone motor. Used the WD bloo@ck, actually found a new WD45 crank, can't remember if rods were both the same but got new of those and we used the WD flat top pistons to get the higher compression. Switch to 12 volt distributor instead of the mag but not sure if it was the right move.
The more electronics and bells and whistles you get the more troublesome. Also you become more dependent and in a certain sense hostage to companies; especially when this equipment because of the electronics can become controllable remotely.
@@toby2581 Think about how long they'll last with better quality machining and modern lubricants. I was clearing snow this week with a clapped out 73 year old Ford that sat with a locked up engine for 40+ years.
You are all forgetting that producing everything from the ground up every decade vs every 75 years is saving the environment by running metal foundries, plastic injection molds, silicone mining, giant power plants, and ... Wait what?
From my 25+ years as a machinist I can verify.... farmers don't fix bugger all till its broken, and that's always during the busy time for them. "It just broke...I need it now.." even though it's been f@cked for the last 2yrs
After 27 years as a Gunsmith and Machinist and Raising Hay I have to agree with you we limp it along till it blows craps and then we are in a bind to fix it. It's always been that way for small farmers. We buy big farmers old junk and make it work because we don't have the $$$ for new equipment especially tractors and bailers etc. Sad But True.
They made things to last back in the day and they made them to be repairable. It was a different mindset and making things last forever didn't result in the manufacturers making more money so it was phased out. So cool to see folks making things better than new.
Up until a year ago my dad had a 5010, 2 5020s, 6030, and a slew of extra heads and a few blocks. He overhauled a couple of them in my lifetime. My grandfather still has his 7520.
Well I learned something from this video, I bought a probably 5th hand John Deere 3020 that the rear end serial number says is a 1965 but, thanks to this, I can confirm the sellers statement that it has been rebuilt since the head uses the later pencil style injectors meaning it is likely not the original cylinder head. I was praying there weren't any glaring problems that caused a bunch of them to need machine work so great news on that front too. Thanks for this video
As a Journeyman Tool & Die maker, always intrigues me to watch automotive machining and the vast knowledge of engine information they attain over the years. Honestly wish I had the opportunity to learn this part of the trade but there wasn’t any shops around growing up. Keep up the awesome videos I really enjoy them👍🏻
Former dealer tech here, I loved working on the old 404 and 466 engines, never did see or rebuild a bendix injector, our area had pencil and Bosch injectors. I rebuilt and set a lot of those. And one 3010 gas with the stupid updraft carburetor, never like those.
I have found that it is often the case that more problems encountered with a brand is in direct relation to them having more umits in the field. The PERCENTAGE of issues in a brand are nearly always LOWER in those cases. Like everything else these days you just hear more about it.
Old iron can be rebuilt completely for way less than new horsepower. Added bonus no electronic junk. A local guy here had a fire in the top of his JD cab, -never even burned the cab or dash and they wrote it off because of all the electronics and wiring there. Crazy.
@@Neoprenesiren Who wants hundreds of thousands of used plastic DEF containers littering roadside ditches and landfills? So called 'green' policies have been moronic from the start, and have accomplished nothing for the planet.
Wow ! You've got a Serdi. Impressive ! Also ,it's soo very interesting to hear a wise experienced person explaining the process ( nothing beats it 👍🏻) . Tnx alot!
Love you're channel fellas i can smell the shop every time i watch. My dad sold nuts and bolts for OEC back in the 80s i would help him on winter brakes a through the summer stocking cabinets in tons of machine shop Loved it .awesome channel. Approved
I’ve rebuilt quite a few John Deere engines. Mostly “newer” four cylinders from the 80’s and 90’s. Most of my daily repair work is still on Deeres that are at least 25 years old.
I remember installing head gaskets on the 6466 engine, and you had to know the casting number of the head and block in order to get the correct bolts and torque specs. I'm not saying they had problems with head gaskets, but... yeah. I'm saying they had problems with head gaskets.
Biggest head gasket issue in my experience operating 3020s 4010s and 4020s for thousands of hours was oil leaking from a passage on the back right side. My solution when replacing the head gasket was to apply an additional head gasket sealant just in that area.
I don't know what year the fuel companies took the lead out of gasoline for off road equipment but for road transportation it was 1974. I think that is when the heads came with harden seats. Please correct me if am wrong. Thanks for the interesting video.
I believe it was 78, but you could buy additives for noncompliant equipment. Had to use it in some old stuff until it was rebuilt for unleaded fuel. I think I even still have a couple old containers of the stuff out in the tractor shed. 😂
As a youth I spent many hours behind the wheel of John Deere tractors. Model “D” distillate fuel hand flywheel start. Model “A” gasoline fuel electric start. Model “70” diesel fuel gasoline pony engine start. That twin cylinder staccato beat is part of me forever. Antiques now but in my mind’s eye I can see them now. The sun coming up found us already plowing and the setting sun said time for supper.
I worked at the Dallas distribution warehouse they have 18 wheelers full of parts daily out to the retail parts stores. Millions of dollars weekly in parts alone imagine the retailer upcharge on parts , a sticker for$40, and the mechanic repair costs
Bought a 4010 50 years ago that a dairy let set up and go bad because of no reverse. I put in a New engine upgrade overhaul kit to 4020 size, sleeves pistons and bearings + valves by myself. It is still running to this day, but I had to sale it when I got devoiced and had to stop farming. It would pull a 14 foot disk all day long with duals and the fuel turned up. Farmer that bought it been using it on a hay farm. Cost me less than $1 to fix the internal shifter after breaking the tractor in half to get to it. Three little springs, but for the JD shop to fix back in1972 the farmer was quoted over $2500 to fix.
Make no mistake. I bet these head are from high hour JD tractors. Dad has a 4020 that used to feed cattle, 30 below 0 and 115. . Bought new, he paid cash for in 1971. 10,000 hours still going strong
And....he does a pretty fair imitation of a master machinist too!! I really enjoy these videos and appreciate the work that goes into filming and editing them as well as the machining work they show. Well done men!!
Love the videos fellas Thank you for sharing all your knowledge and experience, as a 43 year mechanic and a wanna be machinist I truly enjoy watching Sid
Fun JD fact. For the last 20 years their engines are manufactured, and assembled in Mexico. I know this because I used to cut their flywheels on cnc's. Back then they told the company I was working for to build a plant in Mexico, or lose the contracts. That's JD folks. They sent my work to Mexico for tax breaks, and cheap labor. It's really fun competing with 3rd countries now. Funny we use to have laws to prevent this.
It was one reason Trump scored wins Ohio and Pennsylvania. He argued to end such things, and that it would bring back such jobs. Another things that pisses me off is that many of those 3rd world countries cost less to build things, because industries can get away with dumping all kinds of cancerous shit in the environment. I often say that if environmentalists really cared, they would fight 3rd world outsourcing.
@@skylinefever As far as Trump goes. He has never talked about regulating the banking industry. Or putting large tariffs, on 3rd world countries like China, India, or Turkey. Investment banking has brought the working class in this county to it's knees. Because we don't regulate them anymore. Example: A large company in Rockford Illinois. Rockford Products In business a little over 100 years. 4 years ago they were bought out by an investment banking firm. They fired everyone, then shipped the prints to China, and doubled their profits over night. Trump only cares about money, just like the rest. Main difference though Trump despises the working class. Need proof. Want to see the Doritos true colors. Watch the Documentary "You've Been Trumped" He decided he really liked the only wildlife refuge in Scotland. So much so, he decided it would be a great place for a golf course. Then proceeded many underhanded dealings to make it so. In the end. They're both puppets, with dollars & dumb pulling strings. "We Deserve Better"
We had a guy o/h out 466 JD head off a 8640 and I put new sleeves and pistons in the block in frame we ran the engine in our selves and gave it back to the farmer .. days later he rang and said the engine has died .. we got it back to the shop .. pulled the head .. oh boy a dropped exhaust valve trashed piston and sleeve … our machinist chap looked at it and said I see what’s wrong you put the valves backwards- exhaust in the inlet etc … I said the head came from you in a plastic bag full assembled….. the colour drained from his face …. So be careful out there …!
Old technology was both more simple and more dependable than the new stuff. No surprise farmers hang on to their old JD equipment. JD is a common name now in the right-to-repair movement.
And for all the wrong reasons. It's a shame most companies are going full electronic, tractors should remain as reliable and mechanical as possible because they're just tractors and emissions and fuel economy are kinda a moot point on the farm compared to the ability to run it for 16 hours a day 7 days a week without hiccups or breaks. Was surprised the new Kubota my parents bought was still running mechanical injection.
Ok I have to admit I know nothing about tractors and I had no idea what he was talking about, but it's so cool watching someone who's a true expert in their craft talk about it.
Thank you for the video. Very enjoyable. I’ve got a JD2240 with a tired three cylinder diesel. This has helped me to understand what a top end rebuild entails. I’d love to see the same for the bottom since that’s where my issues are (worn rings and blow by). Best regards!
Really glad to see indy's still able to work on some of the JD stuff. I won't buy any JD because of how they are so dead-set on putting indy's out of business with their fight against the rights to repair. Also interesting to see how the "newer tech" valve guides are inferior in serviceability.
My son is very well educated and is a highly skilled machinist. He listens and pays attention as he strives to learn everything I know. His "youtube fame" has allowed our family to have a different avenue to share the machine shop business with people across the world. I'm insulted that you think so poorly of my son.
@@JAMSIONLINE I'm insulted that you replied. The whole running gag "of the cleaner guy" is very tired. And I don't think very little of your son.........I think very little of the people who suckle at the tit of BASIC KNOWLEDGE. There is not ONE single thing you or your son have done on this channel that will change the way machine shops operate. All you and he do is film basic biotch machine work. There is not one single thing or multiple thing or triple thang that you guys have posted on YT that will change how machine shops operate or function. NOTHING. All you've done is monetize basic biotch machine work. That is it. That is IT. All you've done is suckle at the teet of YT monetizers. When you've changed a method; or developed a new method.........Then you get some credit. But just because your Son watched a video on how "to monetize mundane activities" does not grant you a carrot. Wanna see some new diet...........Watch your channel. Wanna see how dog crates are made.....Watch your channel. Wanna see how catfish are farmed.....Watch your channel. Wanna learn a revulationary new machine technique? Better watch something else. Monetization has destroyed you. Suckle at the teet while you can.
@@JAMSIONLINE Hell, you've even got the standard "youtube creator when I don't get a comment I like reply" down pat. Carve your path where EVERYONE HAS BEEN BEFORE. The only difference between them and you is they weren't money hungry enough to form a channel about basic biotch machine work. They kept to themselves, did quality work and didn't care what "nobody" commented on their work. But I guess you and your "vaulted" son need validation from people who have NO IDEA WHAT THE HELL YOU ARE DOING!!!!!!!!!!!!!! They just subbed to a "machine shop" channel because the "tools are cool." Meanwhile, people who have machine shop experience are clicking on videos of bikini models because hot chicks are way more interesting than listening to your son ramble on about you cleaning parts...........
Its also the oldest tractor I consistently see in the shop at our dealer. Some farmers will have a brand new 8R parked next to the 4020 their grandpa bought new in the 60s that gets more seat time than the 8R could dream of
I was about to comment something along these lines - I would assume JD is a popular brand for restorations. It's like everyone restores a Mustang, but not many restore a Pinto!
@@isaacibbotson4632 Right you are. My father in law bought a new 4020 in 1970 and my wife jokingly calls it her high school graduation present. It sits next to that 8R in the shop patiently awaiting spring. Even at 73 with four fractured lumbar vertebrae I would rather drive it - we have both been through a good life.
Is there an advantage or disadvantage making the 4010 head accept the 4020 valves? I’m interested in what you think about the oil pumps on those 40 series tractors. Remanufactured oil pumps are almost $1000. Du you test or rebuild those oil pumps?
Finally got to see how one turn down a valve diameter. Thought Id have to do that on my build but couldnt find any good answer to have its done. I guess its not a very common thing to do.
I love how the cleaning guy has such a wealth of knowledge of the history of each piece he cleans and works on. It's so refreshing. I hope you keep the trend going as you progress in your path in the trade.
My Son is heavily into DRAG RACING from Small blocks, Nitros and Turbo and Blowers, Gas and Methenol........ We also Farm using exclusively John Deeres,,,,, Our machine shop of choicee is located in Augusta Georgia.... I know about the wear items, but not the exact processes by which they were renewed...... I know enough about machining to get myself in trouble.....
I'm from Norfolk (UK). I have to say I love the channel and I bought your gaming mat (when it became available) because I thought it was fantastic. I have a friend who lives in the country and further down their track, a local farmer has a couple of sheds. Thanks to this channel I counted (I think) he has 5 Allis-Chalmers tractors in there (no cabs) in that exact same reddish orange as your Dad's tractor. I thought you'd be interested.
Do you crack detect after you remove the valve seats? Not sure if this required on these heads but something we have to do on larger engines during overhaul.
It's because everyone wants to run old equipment. They can still work on it and get parts easily. They are reliable, LONG working work horses. They don't quit. They're going on 60 years old now, most never apart.
I don't think 40 years old is old at all. I got my first "real job" as an automotive machinist 41 years ago. I was only 15 but learned so much that I will never forget. I'm glad that company overlooked the fact that I was under-age for such work. I got paid dirt but got to put my hands on so much. Dirty but dandy work it was. Pressure testing heads was the worst...wet, cracked hands and all sorts of goofy things made ad-lib to seal the things. Hated that part. That was the job the newbie drew...pressure testing cylinder heads. Yuck to that!

They are on an Apple level, just in the tractor industry.
Or install Chinese Spyware/Cracked John Deere Firmware in order to fix it themselves.
That opening couple sentences are pure gold. I worked in a gear shop for ten years, ten tears ago. Any spare moment in November and December were spent dragging cores out and rebuilding transfer cases and manual transmissions for the winter feeding season. Those old ranchers seem to forget the problems they had in March and April over the summer season.
Given all the anti-repair crap John Deere pulls on their modern hardware (stuff designed to force you to pay a fortune at the John Deere dealer to get your stuff fixed) I can see why people would want to keep their older Deere units (that don't have all that crap) running and working.
I know quite a few equipment handlers have started digging old iron out for that very reason. It’s becoming cheaper to go through and rebuild them vs paying the price of the new equipment that you CAN’T fix!
Supreme court ruled against Deere recently. All mfgs now must obey right to repair act..
@@Nudnik1 True. However a lot of Deere parts are actually another manufacturers parts that have had all part numbers removed. When a card fails, Deere can't get it anymore and you can't find out who made it...... Good luck.
@@kaionski1105 😳 wow
I love the way these tractors can be used for multiple generations.. it's completely amazing.
I love this channel.
This is such a great look into a legit shop.
There is no replacement for experience.
Thank you for bringing us along..
I have a 1971, 4020. It starts and runs so nice. It is quiet also. I was interesting seeing the different year heads. The gas head was cool also, a nice closed chamber but wow were the valves shrouded. Thanks guys. PS. I like Orange Tractors too. I live not to far from where those were made in WI. 😇
When I worked for the City of Santa Ana we had a few JD back Hoes in several departments ! All of the engines had Wet liners that I liked ! Thanks for sharing !
These parts are at the machine shop because they work. The owners are keeping them running because they work. Part of owning something is taking care of it and the machine shop is part of that process. We could dream that we never have to maintain our equipment but with that thought process, the machine usually dies and ends up dead in a bunch of weeds or scrapyard.
I was a former tech at a Deere dealership in McCook, NE. When I started in 1997 there were many Waterloo 404s, 466s, some 7.6L and 8.1L used for irrigation engines. We also had many Dubuque 4045s and 6068s as well. As diesel fuel became more expensive, the diesel engines were phased out in favor of electric well motors. As I recall, the Bosch-style injector was a KDL, and later the KDEL. I called the KDEL the 'easy' injector because it was much easier to tighten down without having to work around the big cast head on the KDL injector.
The way your dad talks is very pleasurable to listen to. He should be an audio book reader! I’ll listen to Moby Dick, from beginning to end, if your father does the narration!
Yes sir, it sure is a pleasure to watch your engine remanufacturing videos. I had the pleasure of attending an automotive engine remanufacturing course at our local community college back in the early eighties, and we covered all of the steps in the process (we had all of the equipment to do a thorough job and of course all of the manufacturing specs). Of course, the equipment you have is needed to be able to do accurate and time effective work nowadays. Your level of craftsmanship and your attitude of making a rebuilt unit better than new is refreshing and I am sure that there are many shops that have that attitude (one shop I use from time to time the gentleman who runs it refers to "restoring a cylinder head" for instance).🥸👍
Love watching the cleaning guy doing his best! Some day he'll get that promotion! Great video!
I have an auto shop in north western PA. I have an auto shop and jobs go in spurts. I'll do 10 oil changes one week and it will be a month before I see another. I've done like 100 gm 2.4 ecotec timing chains. 3 in 1 week for a car lot up the road. Got 2nd one done that week and called to tell them it's done. He was like can ya take a look at a silver Malibu. I was like what's wrong with it I thought I just fixed that one Monday? Nope it's another one same color. 3rd one that week. I am a 1 man operation. Just me doing everything
Doubt life will have a reason to take me out that way again, but man, what a beautiful part of the country. Speaking of old things they don't make like they used to, there's a gorgeous cage elevator a hop skip and a jump from you I'm sure in the National Transit Building. I suppose Blue Streak also qualifies for that category, but I'd sooner trust an elevator that hasn't operated in like 75 years than that rickety contraption.
Love your videos I can relate to your work .I was A farmer my whole life done most of my repairs but never got into your type of work.In Australia my tractors were mainly Fiat can honestly say I
never had a head off or rebuild done.Back then they built things to last.I won’t mention names of my last machines but we’re problems .Cheers love your videos from Bundaberg Australia
Great video, thanks, love to hear the cleaning guy explained stuff, plus I like that he is an AC guy, I have a ‘49 WD that I built a WD45 Clone motor. Used the WD bloo@ck, actually found a new WD45 crank, can't remember if rods were both the same but got new of those and we used the WD flat top pistons to get the higher compression. Switch to 12 volt distributor instead of the mag but not sure if it was the right move.
I love my JD 40 series. It's 39 years old, barely uses any oil and runs like a Swiss watch.
People are repairing their old non emission tractors that actually run until they’re worn out. Thanks
The more electronics and bells and whistles you get the more troublesome. Also you become more dependent and in a certain sense hostage to companies; especially when this equipment because of the electronics can become controllable remotely.
Psh. I’d totally keep rebuilding and running the older, reliable technology. These are from the time before the EPA got their mitts on ‘em.
@@toby2581
Think about how long they'll last with better quality machining and modern lubricants.
I was clearing snow this week with a clapped out 73 year old Ford that sat with a locked up engine for 40+ years.
I'm keeping my pre emissions pickup.
You are all forgetting that producing everything from the ground up every decade vs every 75 years is saving the environment by running metal foundries, plastic injection molds, silicone mining, giant power plants, and ... Wait what?
From my 25+ years as a machinist I can verify.... farmers don't fix bugger all till its broken, and that's always during the busy time for them. "It just broke...I need it now.." even though it's been f@cked for the last 2yrs
After 27 years as a Gunsmith and Machinist and Raising Hay I have to agree with you we limp it along till it blows craps and then we are in a bind to fix it. It's always been that way for small farmers. We buy big farmers old junk and make it work because we don't have the $$$ for new equipment especially tractors and bailers etc. Sad But True.
I have a 1941 John Deere B hand start , best tractor ever . They really are made tough.
We have a machining video on some John Deere B parts coming soon 🙏
We have one that belong to our dad.
They made things to last back in the day and they made them to be repairable. It was a different mindset and making things last forever didn't result in the manufacturers making more money so it was phased out. So cool to see folks making things better than new.
Up until a year ago my dad had a 5010, 2 5020s, 6030, and a slew of extra heads and a few blocks. He overhauled a couple of them in my lifetime. My grandfather still has his 7520.
Great video and how the valve seats can be "saved". But where are my 5020's??? Farmed 3 Sections outside Amarillo back in the day ... what a Hoss !!!
Well I learned something from this video, I bought a probably 5th hand John Deere 3020 that the rear end serial number says is a 1965 but, thanks to this, I can confirm the sellers statement that it has been rebuilt since the head uses the later pencil style injectors meaning it is likely not the original cylinder head. I was praying there weren't any glaring problems that caused a bunch of them to need machine work so great news on that front too. Thanks for this video
As a Journeyman Tool & Die maker, always intrigues me to watch automotive machining and the vast knowledge of engine information they attain over the years. Honestly wish I had the opportunity to learn this part of the trade but there wasn’t any shops around growing up. Keep up the awesome videos I really enjoy them👍🏻
Thanks for the talk. I learned a lot. I know it's not easy to make these videos.
Former dealer tech here, I loved working on the old 404 and 466 engines, never did see or rebuild a bendix injector, our area had pencil and Bosch injectors. I rebuilt and set a lot of those. And one 3010 gas with the stupid updraft carburetor, never like those.
I have found that it is often the case that more problems encountered with a brand is in direct relation to them having more umits in the field. The PERCENTAGE of issues in a brand are nearly always LOWER in those cases. Like everything else these days you just hear more about it.
That’s a great point! And we agree! Hopefully the video made that clear :)
Old iron can be rebuilt completely for way less than new horsepower. Added bonus no electronic junk.
A local guy here had a fire in the top of his JD cab, -never even burned the cab or dash and they wrote it off because of all the electronics and wiring there. Crazy.
Top quality work as always.i love watching you both bring these old units back to better than new in most cases
Cool! I love hearing all the information and commentary. Even though I have nothing to do with tractors or farming it's interesting to hear.
Fellows just ahead up but you have to rotate that mt yoke 90degrees to get cracks in the opposite direction. If not you will miss cracks all day.
no DEF required for these old machines. You two will keep these farmers running forever.

Love you're channel fellas i can smell the shop every time i watch. My dad sold nuts and bolts for OEC back in the 80s i would help him on winter brakes a through the summer stocking cabinets in tons of machine shop Loved it .awesome channel. Approved
I’ve rebuilt quite a few John Deere engines. Mostly “newer” four cylinders from the 80’s and 90’s. Most of my daily repair work is still on Deeres that are at least 25 years old.
Love seeing people do stuff I can't do.
Im a car mechanic and even ive done head gaskets on john deere.....top tip welding washer to valve seat to get out ...every week i learn something😊
I don't bleed green either, but its hard to argue with those generations of JD tractors.
I remember installing head gaskets on the 6466 engine, and you had to know the casting number of the head and block in order to get the correct bolts and torque specs. I'm not saying they had problems with head gaskets, but... yeah. I'm saying they had problems with head gaskets.
Ether never had anything to do with it.......
@Iowagrown123 lol. I wonder if new tractors even have an ether starting aid option.
Biggest head gasket issue in my experience operating 3020s 4010s and 4020s for thousands of hours was oil leaking from a passage on the back right side. My solution when replacing the head gasket was to apply an additional head gasket sealant just in that area.
@@timothyball3144 Not since manufacturers figured out how to put proper-sized starters, glow plugs and intake heater grids on them.
I don't know what year the fuel companies took the lead out of gasoline for off road equipment but for road transportation it was 1974. I think that is when the heads came with harden seats. Please correct me if am wrong. Thanks for the interesting video.
Seats and guides, I believe.
That wouldn't effect diesel engines
@@ACatKrom Exactly
I believe it was 78, but you could buy additives for noncompliant equipment.
Had to use it in some old stuff until it was rebuilt for unleaded fuel.
I think I even still have a couple old containers of the stuff out in the tractor shed. 😂
Great to see the refurb get these awesome engines in op condition.
great video...glad to see someone take'n care of our farmers...!..keep up the great work...thank u...
As a youth I spent many hours behind the wheel of John Deere tractors.
Model “D” distillate fuel hand flywheel start.
Model “A” gasoline fuel electric start.
Model “70” diesel fuel gasoline pony engine start.
That twin cylinder staccato beat is part of me forever. Antiques now but in my mind’s eye I can see them now. The sun coming up found us already plowing and the setting sun said time for supper.
I love watching your videos. The cleaning always teaches me so much! Thank you guys for what you do
I worked at the Dallas distribution warehouse they have 18 wheelers full of parts daily out to the retail parts stores. Millions of dollars weekly in parts alone imagine the retailer upcharge on parts , a sticker for$40, and the mechanic repair costs
Bought a 4010 50 years ago that a dairy let set up and go bad because of no reverse. I put in a New engine upgrade overhaul kit to 4020 size, sleeves pistons and bearings + valves by myself. It is still running to this day, but I had to sale it when I got devoiced and had to stop farming. It would pull a 14 foot disk all day long with duals and the fuel turned up. Farmer that bought it been using it on a hay farm. Cost me less than $1 to fix the internal shifter after breaking the tractor in half to get to it. Three little springs, but for the JD shop to fix back in1972 the farmer was quoted over $2500 to fix.
Makes me want to move to that area of Colorado to be near such a good Machine Shop .
What a great video. Packed full of interesting and useful information.
Many thanks.

A great and very informative lesson on John Deere cylinder heads guys! The cleaning guy knows a lot about them, Listen up Junior!
Ancient shop saying. "Ashes to ashes, dust to dust. If it weren't for John Deere, my tools would rust."
You can literally put any brand name of any industry brand into that saying.
Make no mistake. I bet these head are from high hour JD tractors. Dad has a 4020 that used to feed cattle, 30 below 0 and 115. . Bought new, he paid cash for in 1971. 10,000 hours still going strong
I use to make the cylinder heads for John Deer, and Caterpillar. Back in the 90s.
I cannot remember the JD head I made, but I made the 3176 heads.
That cleaning guy knows his stuff!
And....he does a pretty fair imitation of a master machinist too!! I really enjoy these videos and appreciate the work that goes into filming and editing them as well as the machining work they show. Well done men!!
Love the videos fellas
Thank you for sharing all your knowledge and experience, as a 43 year mechanic and a wanna be machinist I truly enjoy watching

Fun JD fact.
For the last 20 years their engines are manufactured, and assembled in Mexico.
I know this because I used to cut their flywheels on cnc's.
Back then they told the company I was working for to build a plant in Mexico, or lose the contracts.
That's JD folks.
They sent my work to Mexico for tax breaks, and cheap labor.
It's really fun competing with 3rd countries now.
Funny we use to have laws to prevent this.
It was one reason Trump scored wins Ohio and Pennsylvania. He argued to end such things, and that it would bring back such jobs.
Another things that pisses me off is that many of those 3rd world countries cost less to build things, because industries can get away with dumping all kinds of cancerous shit in the environment.
I often say that if environmentalists really cared, they would fight 3rd world outsourcing.
@@skylinefever
As far as Trump goes.
He has never talked about regulating the banking industry.
Or putting large tariffs, on 3rd world countries like China, India, or Turkey.
Investment banking has brought the working class in this county to it's knees.
Because we don't regulate them anymore.
Example:
A large company in Rockford Illinois.
Rockford Products
In business a little over 100 years.
4 years ago they were bought out by an investment banking firm.
They fired everyone, then shipped the prints to China, and doubled their profits over night.
Trump only cares about money, just like the rest.
Main difference though Trump despises the working class.
Need proof.
Want to see the Doritos true colors.
Watch the Documentary
"You've Been Trumped"
He decided he really liked the only wildlife refuge in Scotland.
So much so, he decided it would be a great place for a golf course.
Then proceeded many underhanded dealings to make it so.

We had a guy o/h out 466 JD head off a 8640 and I put new sleeves and pistons in the block in frame we ran the engine in our selves and gave it back to the farmer .. days later he rang and said the engine has died .. we got it back to the shop .. pulled the head .. oh boy a dropped exhaust valve trashed piston and sleeve … our machinist chap looked at it and said I see what’s wrong you put the valves backwards- exhaust in the inlet etc … I said the head came from you in a plastic bag full assembled….. the colour drained from his face …. So be careful out there …!

I got a 97 obs suburban 454 I need rebuilt. I plan on dying driving that truck.
I just wish we could get these parts made in the US instead of you know where. Beautiful work.
Old technology was both more simple and more dependable than the new stuff. No surprise farmers hang on to their old JD equipment. JD is a common name now in the right-to-repair movement.
And for all the wrong reasons. It's a shame most companies are going full electronic, tractors should remain as reliable and mechanical as possible because they're just tractors and emissions and fuel economy are kinda a moot point on the farm compared to the ability to run it for 16 hours a day 7 days a week without hiccups or breaks. Was surprised the new Kubota my parents bought was still running mechanical injection.
I think about what electronic engines are good and which ones suck. I mean people are happy to do what it takes to keep the Ford 7.3 PSD going.
New subscriber here. Watching this video about these old cylinder heads is the reason I still daily drive a 1st gen Cummins.
Ok I have to admit I know nothing about tractors and I had no idea what he was talking about, but it's so cool watching someone who's a true expert in their craft talk about it.
Thank you for the video. Very enjoyable. I’ve got a JD2240 with a tired three cylinder diesel. This has helped me to understand what a top end rebuild entails. I’d love to see the same for the bottom since that’s where my issues are (worn rings and blow by). Best regards!
Really glad to see indy's still able to work on some of the JD stuff. I won't buy any JD because of how they are so dead-set on putting indy's out of business with their fight against the rights to repair. Also interesting to see how the "newer tech" valve guides are inferior in serviceability.
My dad was a mechanic at a John Deere dealership from 64-70. The 4020 was their big bad machine. These days I see them used as yard tractors.
Thanks again for the content and thanks SBI valvetrain
Truly enjoyable to watch craftsmen at work. It’s nice that you let your dad be the star, but you clearly know your craft as well.
His dad forget more yesterday morning than this kid will remember. All this kid "knows" is youtube fame. His dad has skills. The son has pills.
My son is very well educated and is a highly skilled machinist. He listens and pays attention as he strives to learn everything I know. His "youtube fame" has allowed our family to have a different avenue to share the machine shop business with people across the world. I'm insulted that you think so poorly of my son.
@@JAMSIONLINE I'm insulted that you replied. The whole running gag "of the cleaner guy" is very tired. And I don't think very little of your son.........I think very little of the people who suckle at the tit of BASIC KNOWLEDGE. There is not ONE single thing you or your son have done on this channel that will change the way machine shops operate. All you and he do is film basic biotch machine work. There is not one single thing or multiple thing or triple thang that you guys have posted on YT that will change how machine shops operate or function. NOTHING.

Wanna see how dog crates are made.....Watch your channel. Wanna see how catfish are farmed.....Watch your channel. Wanna learn a revulationary new machine technique? Better watch something else. Monetization has destroyed you. Suckle at the teet while you can.

@@JAMSIONLINE Hell, you've even got the standard "youtube creator when I don't get a comment I like reply" down pat. Carve your path where EVERYONE HAS BEEN BEFORE. The only difference between them and you is they weren't money hungry enough to form a channel about basic biotch machine work. They kept to themselves, did quality work and didn't care what "nobody" commented on their work. But I guess you and your "vaulted" son need validation from people who have NO IDEA WHAT THE HELL YOU ARE DOING!!!!!!!!!!!!!! They just subbed to a "machine shop" channel because the "tools are cool." Meanwhile, people who have machine shop experience are clicking on videos of bikini models because hot chicks are way more interesting than listening to your son ramble on about you cleaning parts...........
Just for your information, the 4020 is probably the most restored John Deere of the non antique years.
Its also the oldest tractor I consistently see in the shop at our dealer. Some farmers will have a brand new 8R parked next to the 4020 their grandpa bought new in the 60s that gets more seat time than the 8R could dream of
First tractor ride was around 1977 on a 4020. Spent many hours sitting on an uncomfortable fender listening to am on the radio.
I was about to comment something along these lines - I would assume JD is a popular brand for restorations. It's like everyone restores a Mustang, but not many restore a Pinto!
@@isaacibbotson4632 Right you are. My father in law bought a new 4020 in 1970 and my wife jokingly calls it her high school graduation present. It sits next to that 8R in the shop patiently awaiting spring. Even at 73 with four fractured lumbar vertebrae I would rather drive it - we have both been through a good life.
@@mattabbey9190I would love to see a restored pinto driving around.
Is there an advantage or disadvantage making the 4010 head accept the 4020 valves? I’m interested in what you think about the oil pumps on those 40 series tractors. Remanufactured oil pumps are almost $1000. Du you test or rebuild those oil pumps?
Here in Denmark it really started with the newer xx30 series cylinder heads.
John Deere heads gives da cleaning guy something to do. Job security.😊❤
just redid my 3020 gas did a cold start yesterday at 10 below fired right up. the 3020 gas is known for poor carb performance
Brandon, I came along for the rebuild videos, you’re stuck with me! Keep up the great work, I’m excited for your future!
Finally got to see how one turn down a valve diameter. Thought Id have to do that on my build but couldnt find any good answer to have its done. I guess its not a very common thing to do.
0:34 The tractor engine that head was on hasn't ran for 30 years.
This was a really good video. I own an no letter 410 from the mid 70's so seeing it's sisters engines on the bench is cool.
I love how the cleaning guy has such a wealth of knowledge of the history of each piece he cleans and works on. It's so refreshing. I hope you keep the trend going as you progress in your path in the trade.
The Cleaning Guy had me on the edge of my seat every time he turned one of those cast iron boat anchors, I mean, cylinder heads.

I'm from Norfolk (UK). I have to say I love the channel and I bought your gaming mat (when it became available) because I thought it was fantastic.
I have a friend who lives in the country and further down their track, a local farmer has a couple of sheds. Thanks to this channel I counted (I think) he has 5 Allis-Chalmers tractors in there (no cabs) in that exact same reddish orange as your Dad's tractor. I thought you'd be interested.

Do you crack detect after you remove the valve seats? Not sure if this required on these heads but something we have to do on larger engines during overhaul.
Man, the cleaning guy has a surpising amount of in depth knowledge about the heads from these old tractors..
You guys are artists
4020 jd was a good tractor i used to run one when i was a kid along with a 2840
It's because everyone wants to run old equipment. They can still work on it and get parts easily. They are reliable, LONG working work horses. They don't quit. They're going on 60 years old now, most never apart.
Love your videos. Thank you.
I don't think 40 years old is old at all. I got my first "real job" as an automotive machinist 41 years ago. I was only 15 but learned so much that I will never forget. I'm glad that company overlooked the fact that I was under-age for such work. I got paid dirt but got to put my hands on so much. Dirty but dandy work it was. Pressure testing heads was the worst...wet, cracked hands and all sorts of goofy things made ad-lib to seal the things. Hated that part. That was the job the newbie drew...pressure testing cylinder heads. Yuck to that!
