The fact that Auggy is still snow white in a machine shop shows just how clean and organized your shop truly is!
Or, Auggy goes to the groomer regularly.
I was thinking the same thing !
Made a comment to my wife, very daring to have a white dog in a machine shop.
@@stoddern Augie is an outdoor farm dog. He gets to come in the shop on rare occasions. He has never gone to a groomer and only to the vet for vaccinations. In fact no one wants to take him anywhere. He pukes every time he goes for a car ride!
The cleaning guy found the camera again and we are happy that he did😉
Yep, the cleaning guy is always trying to get into some sort of mischief😮
Is there an update for the Allis Chamers,
Wow ! What memories! I was a mechanic for 50+ years on forklifts, I rebuilt so many Continental, Hercules and Waukesha engines I dream about that a times LOL , seeing you strip down this old f head reminds me of my youth , most of the engines had Castle nuts with pins on then or safety wire ! The best time was standing them up on the bell housing when done and painting them , great satisfaction from that job !
Did you paint them Red or Black or Orange? Some customers liked the Dodge Hemi Red or Orange. It showed where they leaked after you broke it in and the customer could prove to their friends that it was actually removed and rebuilt and not just re ringed..
Until you mentioned it here, I had forgotten all about it. I vaguely remember seeing only one motor with wire retainers. My boss in one of his mechanics we'll talk about the farm life and using Ingenuity to fix broken machineries. When they got flat tires they would stuff them with hay to get the job done until they could get the time and or money to fix it properly
@@billvandorn5332 My dad was a jet engine mechanic in the Navy 1954 -1959. And my dad was a character. When in Port, my dad liked coming home on the weekend. The easiest way to come home was to steal a plane off the repair line. The easiest way to get a plane off the repair line was to fix it when no one was looking. There was a certain cargo plane with a blown up radial engine that no one would miss that needed a piston, rod and jug. His buddy got on the phone, called a base that had one. Said he was a General and he wanted it right now. It was taken out of inventory, put on a jet fighter, flown at great expense to the government. When it got there, priority one, it took my dad two hours to put it back together. They filled a flight plan, fueled the plane with enough fuel to go from Pensacola Florida to Pittsburgh PA and took off. The Pratt and Whitney engine shook, the Push Rods shook loose for the valves, it developed a leak, they had to turn around and come back. The plane had to dump all the fuel before it could land. There was my dad's 50 Chevy sitting at the end of the runway with a empty tank. My dad forgot to safely wire the bolts on the engine and it shook loose. When it came time for promotion he didn't get one because of one stupid mistake. When it came time to re-up he quit because he was working beyond his pay grade and there was no slots available for his job at what would be a E-5 in the other branches of the military. One mistake that cost him his whole career in the military.
My buddy Kenny would stuff flat tires with leaves when he was in the middle of the woods with his dirt bike. It's probably common knowledge for them,but seemed inovative to me.
For what it’s worth I work on them currently, those engines are still out there and we still overhaul them. I carry 2 sets of zip wire pliers 😊. Good engines if they can keep oil in them
Worked for a Jeep dealer in Tulare, CA in the mid 1970s. They bought an entire truckload of used surplus 4 cylinder Jeep engines. We rebuilt a few dozen of these engines using surplus WW2 parts. It took longer to clean the cosmoline preservative off some of those parts than it was worth. We would test run the rebuilt engines on the bench while they were sitting on the oil pan. Those engines were used in all sorts of agricultural equipment as well as all early Jeeps.
When Kaiser owned the company they had a exchange program where you could purchase a rebuild engine with a warranty. Long before Jasper and all the aftermarket exchange programs or Goodwrench crate motor. Kaiser really did love his jeep company..
My uncle had an old Willys pick-up with a flatbed. That was back in mid-50's that was his farm utility vehicle. He'd run them until they would go no more. Good old truck.
I understand that the dealers weren't to worried about model years. They didn't issue the model year until it was sold. They are hard to identify the years. The fact that the model and ID number tag is held on with 4 slot head sheetmetal screws makes them real easy to swap😂.
This gentleman is a surgeon on these motors. Haven’t seen anyone better !
I bought a '52 Willy's 1 ton 4wd from my maternal Grandpa for $357 when I was 14. I pulled the 134 F Head out and my Dad and I rebuilt it. Had to bore it .030" over. Had to sell it in college but bought it back. GOOD MEMORIES!!!!
I see that The Cleaning Guy has embraced power tools. When you first started this channel, he was a speed handle guy.
Jim, as a truck owner operator in so cal in the early 80's I ran distilled water and Nalcool, no anti freeze in my small cam Cummins. Pops taught me that way as we only ran over to Phoenix or Tucson or north to the bay area or Sacramento for GI Trucking at that time. Early in my career I remember one trip between Phoenix and Tucson it snowed a bit. The trucks grill had collected some slush and I remember worrying about a tube freezing in the radiator core and splitting. By the time I got down to Tucson it was sun up and all was good. Nalcool was oxblood red and would leave a telltale red stain if there was a coolant leak anywhere. It's main purpose was to lessen the pitting of the wet side of the cylinder liners from cavitation and inhibit corrosion. Nalcool was basically equal to what Cummins sold as DCA at that time. Distilled water and Nalcool did great in my experience with my second truck a 1986 IH 9670 Eagle with an NTCC 400 big cam Cummins. We ordered that truck with optional large radiator, a Modine beta weld. I could remove the radiator cap and see clean bare copper and clean silver solder inside the filler neck just like when it was brand new, even 10 years and 1 million, 30 thousand miles later! That truck came with a small spin on coolant filter for which I remember buying Nalcool branded filters that had a dose of cooling system treatment inside them. In 1992 I moved to Reno Nevada and quickly had to find low silicate anti freeze to add in the coolant mix now that i would be running over Donner Pass everyday. Had to buy and install a plug in block heater and an ether inject starting aid for that Cummins. Things we never thought about when living in the banana belt.
I'm glad to hear that someone besides me remembers the old days when 100,000 miles on an engine was almost a miracle. My sons always look at me like I'm crazy when I tell him about the old days. When I went to work for the Subaru dealership in 79 I was very impressed with the number of miles people getting on those engines. We had a couple of surveyors that had the Subaru Brat and they had over 300,000 miles apiece on them and that almost blew my mind.
Subaru used to build a good engine.
Yes ! My Dad had mostly Fords in the 1960's and early 1970's and one Oldsmobile. Around 90,000 they would start using oil and running badly! I recall him taking the valve covers off his 429 Thunderbird engine and it was absolutely filled with gunk! It barely ran so he ending up selling it for maybe $150 ! 😂😂
Engines in the 1950’s were designed for non detergent oil. Contaminants in the engine oil would fall out f suspension and collect in the oil pan, top of head, etc. carbureted engines often ran rich generating deposits. Removing sludge from engines regularly was expected. Detergent oils came out in 1960’s. Detergents keep contaminates in suspension. When oil is changed the contaminates are removed. Some people used non detergent oil and sludge developed. I remember my dad cleaning sludge out of the engine in our AMC station wagon. I think he ran non detergent oil because he did not trust the new oil. Or to save money.
Absolutely. My dad ran a '53 Ford to 90k and a '65 Fairlane to 140k. It took one valve job for each where he got the valve stems knurled to reduce leakage through the guides. My 10 to 16 year old self was his parts cleaner! Good memories. Oils and metallurgy have come a long way.
@@spaceghost8995My dad put 100,000 miles on his 1946 Ford panel truck with 59A V8 engine. He had 30W Wolf’s Head oil and the filter changed every 1000 miles. The engine had an oil bath air cleaner a bi- pass oil filter. Wix cartridge filters were commonly used. The truck had a three speed transmission but he never used second unless absolutely necessary. He preferred to go directly from first to third.
Congratulations to Nicholas! And to you, Jim, for knowing about that bolt hidden in the intake! Love the channel!
Newbe camera operator did a fine job! His lack of knowledge coaxed some extra explanation out of the old man. I've watched enough motor builds and enough of your videos to know enough to be dangerous, but having a little more explanation for the why and what for is lovely. Sometimes, some of the basics you guys take for granted aren't clear to me and just a little more context is all I need to put it all together! Keep up the good work!
Yes, it is all of those second million little bits of knowledge that make up the difference between a run of the mill professional and an expert. 😮 The first million little bits make up the difference between me and your run of the mill professional technician! 😅
Thank you guys!!! Awesome show as usual.
Thanks for watching!
I've been watching your channel for awhile now. I find it both interesting and informative. I never leave comments, but I have to this time. The reason being I am rebuilding a 55 Willy's Hurricane 6 flat head. I learned a lot. Can't wait for the machining videos of this engine. Thanks
You’re videos and cutting edge engineering videos are absolutely my favorite hands down 👍🇺🇸🇺🇸
I've never worked on a Jeep engine but Dad and I worked on so many cars and tractors from the 20's through the 50's. Boy that brings back good memories. You never knew what you'd find when you took an engine apart. Our last project that we were going to work on, a 1925 chevy truck, is still sitting waiting where Dad parked it 30 years ago when I finished college and moved away for work. He's been gone 15 years now.
Tuning in here, all the way over the pond from little old England just to watch the cleaning guy tear into this engine.. Love your work guys.. a subscriber for life here..😃👍
As one who is a little senior to the clean-up guy, I really enjoyed this one.
When I started working as a mechanic in 1975, my job was to tear down these engines and send them to the machine shop. Then reassemble them whenever they were ready. We had a fleet of 30 Jeeps with this and the flathead versions. We had lots of spares.
30 Jeeps?? Were they postal Jeeps or ice cream trucks or what??
@@JeffKopis No they were used for spraying mosquitoes. We put a 60 gallon tank in the back and ran a pump off of a pro. We used to go to the army surplus and buy jeeps and parts. We could not use the bodies or frames. It was a county agency. I got really good at pulling motors, under 30 minutes.
Absolutely enjoyed this segment. Neat old engine
Congrats on the baby! Nice fill in camera work Josh. Enjoyed a look at this Willys Hurricane.
I don’t recall ever enjoying a teardown as much as this one. I learned of exhaust in the block, intake in the head, pins to prevent main bearing rotation, offset slot for distributor drive, (early Ford flathead had an offset drive slot (my Dad taught me that) tapered bolt’s from back to align flywheel. All kinds of interesting stuff. When this 73 yr old thinks he’s seen a lot, I see a bit more ……. I like it. Thanks for a great way to spend an hour of time 😃
Early engines used oils that had no detergent additives to keep contaminants in suspension. It was entirely intentional in the design that the contaminants would settle in the sump as sludge and stay there. The float for the oil pick up was so the oil was drawn off near the surface not down at the bottom where all the sludge collects. Detergent additives began to be added to oils once engines began to be fitted with oil filters. Today, small engine lubrication still works in this way and it is the main reason manufacturers specify special small engine oils for them that don't have detergent additives
I was going to say the same thing!
The cleaning guy is such a humble legend. Could watch him for hours
I live in Australia, born in 1953. When I was in high school one of my friend's father had a GM Holden (Australian designed and built car) It had about 120,000 on the clock. The new detergent oils came out and the dad agreed to have it put in his engine. It worked really well and removed all the gunge and muck from the rings. Needless to say, the engine was clean but removing all the carbon meant it now used more oil than petrol. As Jim said 100,000 miles was the life of these engines.
I wonder if this engine was the one from my friend A.L. Podva's truck? It was green, muddy, probably a little rusty, and always had a bed full of hay and barb wire fence stuff. He owned a ranch in the hills of Danville, CA and drove that truck around in the hills and on the streets of the town for decades. I was a runner and would chase his cattle off the streets back up into the hills and he would come by and fix the fence. Sometimes I would help him with the fence too. He was a super nice old guy and brought me a Christmas gift for years. He always had a smile and dried Copenhagen on his lips. I follow this channel - what a coincidence if it is his truck! 😊
Way back in about 1980 I rebuilt one of these, the bores were trashed, I bored it to 60 over with a Sunnen hone, I put 2 to 3 thousands taper in the bores, That was an experience I won't forget. We did it in-frame to save the customer the R&R labor.
God Bless you all for what good work you provide for your local farmers and working man. Happy Easter ❤
Indeed!
AMEN for sure thanks for sharing this with us
LMFAO your son in laws comment about his engine had me cracking up. What a good sport of him to come help out when you guys need an extra hand, that's truly what family is all about
Pretty darn clean inside, even with the gunk in the pan. I bet this had a re-ring job done on it in the past.
First Engine I ever helped Overhaul was an Earlier 134 Flat Head. I was about 16 or 17 and the guy I helped Dad owned a repair shop and he tutored us. Ran good when we got done and we spent many Hours running around in a pretty clean CJ-2.
This man is the absolute baddest!!! Honest and professional... Hes the engine doctor and his son is the shit too. These men are honest good men. So refreshing
I have been an engine re-builder and sports car high performance modified engine supplier in my past life(retired). I use generally diesel engine oil after break-in of a rebuilt engine where for Gasoline engines I used SI-5W30 for the first 1,000 miles running and then service with SI-CI 30W50 as the ambient temperature is above freezing and to 40degC. When all the new fangled oils with additives became prevalent, 1970s/80s, and servicing Ford XD/XE era on-wards, it became common for the additives to accumulate in the bottom of the sump so deep that oil would not drain without using a screwdriver to dig a hole to release the oil. We were removing sumps in so many vehicles that servicing was always over budgeted values. The sludge additives, as sent for analysis, showed that they were not being maintained in suspension in the nominal base oil. This was the main reason I used the compression ignition oils for most of my gasoline engine servicing. The sump was mostly just a carbon grime in the sump as the compression ignition oil detergents washed the internals of the engine. Later specifications were for both spark ignition & compression ignition in the 1980s onwards. Porche and another sports car manufacturer took Shell on over the rapid deterioration of the engines due to oils not maintaining the lubrication as claimed. Just a bit of background on oils as I was taught in the Air Force and also by a mate who was a Chemical engineer for the Shell company back in the 1970s/80s. Ozzie Follower
Absolutely loved this video. The detail and explanation shows the incredible amount of knowledge the "cleaning guy" has. Love the detail and explanations!!!
I am just amazed you have so much understanding for this old engine. I was five years old when this engine was made.
I know someone who has a head for this beauty… I asked what the rarest heads in his machine shop were and Willy’s hurricane was his answer
Really enjoy watching these old engines being torn down and reconditioned by someone who knows.
You are an Old School Perfectionist. Very few of you left around, Love the video's. Don, CA. 4-1-2024.
The bypass filter...some of the oil was pumped into the canister filter...all the oil went through the pump unfiltered. One bypass filter which used a roll of toilet paper as the filter medium was the Franz filter...sometimes used as a supplementary filter to the OEM full flow engine filter. Most OEM used the "normal" cartridge filters we know and love today....before the spin on filter.....
I love watching you work Sir! A close friend invited me to wrench on his '51 f-head last spring but we only went as far as cleaning up valve seats before she ran again. I always wondered what the rest of the internals looked like and now I know. A great project, thanks!
My dad has a block of wood painted black with numbers on it that was made just for keeping the old valves in order when you disassembled it so you could put them back in the same hole in the block and heads.
Excellent job josh! Thanks for filling in. Good camera work with plenty of detail and competent framing. Enjoyed this teardown vid tremendously.
Absolutely love this tear down video. Excellent job in doing so and the back up camera man did awesome.
Thanks Josh!
Thanks for the trip down memory lane. Before he passed in 2010, my Dad owned a restored 1952 Willys Aerowing automobile. It had a six cylinder F-head motor much like the 4 cylinder version in this video. It was coupled to a 3 speed on the tree with electric overdrive. Surprising thing was that the automobile was unibody! Unibody was kind of rare back in those days. It got about 26mpg using the overdrive.
Scott @ C&C Equipment carries a great deal of parts for Willis jeeps.
I really appreciate how neat, clean and methodically you guys work.
Brings back memories. Many years ago I had a 1943 MB Jeep with a 4 cylinder flat head engine. It sure was so easy to work on.
This is an awesome look into a classic, you guys do a great job really going over everything you need to know and all the little tips and tricks.
This popped into my feed, and a few minutes in, I'm subscribed. Jim definitely seems an easygoing guy, the kind where you want to pull up a chair and hear what stories he may have, and learn from his treasure trove of knowledge.
I like how twisted off bolts are just matter of fact, run of the mill, everyday work!
I love this channel and it brinks back memories of my auto-shop days in high school learning from Mr V about the good old days of racing and automotive. You have an awesome memory and your customers are lucky to have you working on these rare old engines. I'm so happy to see your son following in your footsteps and keep the tradition of quality machinist alive and well. I was wondering about that one tooth off on the crank/cam gears and wonder if that was the cause of the overheating and bearing damage? I can't believe just one cam bearing and the rest metal to metal.......WOW. Thanks so much for all your videos and the trips down memory lane.
Thanks for showing us the insides of a unique post-WW2 motor! Not too many F-head engine rebuild videos exist and you are setting a high standard. Likely to have very good parts support for that motor.
There is a small hole in the side of the filter housing center tube that must be cleaned out or oil will not flow through the filter to the timing set. Also this is a partial oil filtering system. not all oil is filtered. You can increase the oil pressure to the #1 main bearing by welding the hole shut on hex oil tube that sprays onto the timing gear set and re-drill it to .040" .
50:05 Oil galley. Thats what we called it. In chev 283, ford 289 etc. Must have come out of a Chilton manual in a past life. This Jeep engine is a bunch of fun to watch. Thanks guys.
I've been looking forward to watching this one all day!
Really neat seeing the more rare engines being reworked. Great job!
WE just had to replace the rear main seal in my project car 's engine after it was rebuilt in another shop. The neoprene seal was not correct for the engine, was gobbed up with silicone and leaked like a sieve. We also cleaned out the oil pick- up , which was choked with crud. We stripped and cleaned all the oil gallys ( there you go Jim ) and cleaned the lower block. put the main bearing caps on the right way around cleaned the crankcase . we inspected all the bearings and used assembly grease and reassembled, and re installed the unit into the car , she started and runs very nicely . But I learned an important lesson, check every thing !
Jim, I use a large drill chuck to pull pins with. Just put it on, tighten it down, and a light twist and pull is all you need, no more fighting it with pliers. You could even put a handle in it.
Congratulations and Happy Easter!
Love watching you guys!
Thanks for watching!!
Big jeep fan. Thanks for doing this video.
A pure joy to watch!
These are always enjoyable videos. Thanks!
Great find for me to find your channel, now I'm just sitting in the gallery watching you explain what a galley is. Too old to change at this point. Really enjoy your site.
Love this channel because of the amount of knowledge and the oddball stuff that gets worked on.
This is going to be an interesting project to watch. And it's going be fun to see how well it goes For you when you are done with it? I am just glad that it's you that is doing this one and not me. There just seems to be a lot more to these engines than engines of today's technology.
My dad had a’56 Willys which I drove when I was a teenager. It only went about 40mph but was great in the woods.
When I was learning engines in the 80’s, I was taught the term oil galley and galley plug. Also known as oil passage. Lol
I grinned from ear to ear when you mentioned your Dad making the bolt puller for you long time ago. Funny how we don’t forget how much our Dads helped us along, so we can pass that along to our Boys ❤️👍
I do not know for sure on the F heads. But on my original 1944 GPW L134, you time it by the flywheel so the tapered pins only allow it to go on 1 of 2 ways when I assembled mine I put it on 180 out:(
😂😂😂🎉🎉😂😂😂
If you guys get this relic back together and running I will be forever impressed!
This is really cool. My L134 Go Devil is almost done with its rebuild. Cool see these steps.
Howdy Josh, thanks for your filming duties. First time watching one of these engines been worked on. Thanks for sharing your knowledge.
Cool. I rebuilt one in 68. It's was so easy, so simple.
My first engine rebuild was an F head out of my uncle's jeep panel truck. It was the delivery vehicle for his dry cleaning business, so got a lot of stop and go driving. It was 1959, and I had just graduated from High School. Used a Motors manual from the public library to help me get through the job. The truck was still going strong when I returned after a four year hitch in the USAF. Thanks for the memories.
Pumped a bunch a gas in those ...had a customer that owned one ...did very well crawling around in the snow... good content and thanks
Good update keep it up the good work and God bless you 👍👍👍👍
Thanks for the video. Happy Easter
Absolutely mesmerizing video..... From a Fl. Drag racing guy that pays machinist an awful lot of money!
@1:26 The timing gears were one tooth off!! @34:15 that is just what you said!! Great minds think alike, brother!!
I’m a mechanic, or have attempted to be over the 40 plus years I’ve been turning wrenches. I have always wanted to be a machinist and do all that awesome “old school cool guy” stuff! Big difference between a mechanic and a machinist! Love your channel, and new subscriber here!
Great video and really enjoyed what you had to say about this engine.
Around 29:00, I like how Jim is barely turning the impact when the rod nuts don't want to come off as easy. Just a funny observation because I do the same thing. Great tear down video! A lot of knowledge being shown.
And I thought I was the only one who did that.
You’ve got my head spinning with the floating oil pickup. A necessity with older non-detergent oils, but not any more. I went through the motions of cleaning out the sludge in the oil pan of a continental 226, and now I wish I would’ve welded or pinned that oil pickup to eliminate the floatation. Might be going back!
I'm with you, oil galley
Congrats Nick! Had a 390 ford that did that to the cylinder wall. The previous guy forgot a snap ring and the timing chain oil slinger.
Galley is correct… Don’t let these youngsters corrupt you. And thanks for videoing this tear down… I know we gave you a hard time the last time you tore one down without a video
It’s a galley for this 48 yo person.
A “galley” is a type of boat or a kitchen. A “gallery” can mean a long enclosed passageway or corridor. It’s definitely supposed to be gallery. Everyone knows what you mean so it’s not really that important, but don’t be surprised if you get corrected.
People in Texas to this day run fairly new vehicles with plain water in the cooling system. They are actually surprised when freeze plugs pop out when the temps drop to 22 degrees.
Freeze plugs are a misnomer. They're not meant to pop out in freezing weather, and often dont. Im a scrapper, and I couldn't count all the freeze cracked blocks Ive seen. Those plugs just fill the holes meant for removing casting sand from the water jackets at the foundry!
Nice to spend some time with 'Dad' again, enjoyed this :)
I'm no mechanic , but that was a fascinating 55 minutes.Like watching Columbo forensically diagnose the engine's history.
Great video. Good job Josh!
I wear gloves daily in my job. Changing to a clean set of gloves happens a lot and the sweat on your hands makes it difficult to slip the replacement gloves on. Wearing two sets of gloves allows for easy replacement of the outer pair. 👍🏽
Such rugged designs that these earlier machines were.. Not made for 1/4 mile acceleration competition, but if you needed dependable power for industrial duty applications; these heavy little 4-bangers were the ones that could be relied upon to get the job done... They made it through several wars, and then they were overhauled and re-purposed when those bodies & frames , went to heaven... That's Quality !!!
Absolutely loved this ❤
Can’t wait to see this one built back up!
The piston with the pin that rode the cylinder wall has a different style oil control ring in it. Someone went in, re-ringed it, and didn't center the pin properly.
Upon further inspection after we were done filming, we noticed that too. The pin has a notch where the cinch bolt goes through, so it has to be centered properly. The crank end of the rod is offset. We have since determined that rod assembly was installed backwards and the rod offset caused the piston and pin to crowd the cylinder wall creating the grooves.
I really enjoy this channel. Very educational and the people in it are all great, just the type you would like to have as neighbors. About old car engines, I inherited my grandparents all original 48 Ford Super Deluxe. It had about a half inch of old oily sludge in the oil pan we removed. Fortunately, my grandfather had a canister type oil filter on the engine so that probably helped save the engine. The engine didnt need rebuilding, just some maintenance at 57,000 original miles. Engine is very quiet and runs as well as you would ever expect from a vintage Ford flathead. Great channel.
I had one of them. Oh! Memories!
Cool. A little piece of history
Absolutely fascinating as ever! This prior generation of engines were so much more... accessible to humans. Modern machines no doubt make sense to other machines but these were built by hand, or at least hand tools and some amount of handicraft. Beautiful work in its own way.
Looking forward to this series
You are such a legend man. Subscribed for life.
