The cleaning guy appears to show a good aptitude for this line of work. I recommend he be promoted to the machine shop. Mind you mucking out pig sheds and scrubbing toilets is an honorable trade, but he's got a gift here!
On the subject of balancing, as a power generation engineer, we had a gas turbine generator that had developed a severe vibration. Rather than spend over $100,000 to remove the generator and transport it to the manufacturer’s repair facility, we brought in precision vibration analysis equipment and identified the direction and magnitude of the displacement. A single 1/4” flat washer was added to a balancing post on the rotor which was peened over to hold it in place. This solved the vibration and saved $100,000 plus weeks of downtime. One single hardware store washer!
Funny enough I test and balance rotors for GE. Even we use washers at the couplings to balance. Crazy what a couple grams can do to balance a 50 ton unit.
I'm an old guy who never knew what I wanted to do for a living. After watching your videos I now realize what I was made for. (I was a FedEx guy until I retired in 2007) Next life I guess Thanks for your excellent work.
Jim you are a master craftsman. I was an apprentice mechanic in the late sixties. We used to take our machining work to a couple of " old boys" in a workshop full of machines, probably pre-war, or war surplus. they always did a perfect job. later I encoutered newer shops with newer machines, but you didnt get the quality. Thank you for showing us your workmanship. All the best to you and Nic, from here in the UK.
I'm an electrical engineer, so am really interested watching you work your magic on a crank. I don't know if you have a degree or certificate in your line of work, but you COULD be a great teacher, & teachers are indispensable, especially in our 'throw away' society now. ALWAYS enjoy watching you, guys, but THIS video just shows how knowledgeable you are, & how much money you charge is worth every cent! Thnx You were always better than the "cleaning boy" we last saw you as:)
I just watched a video about the restoration shop at the Pensacola Air Museum... The machinery in the machine shop was to die for.. I was thinking the same as you, are there young people coming up being taught how to use these machines????
Engine repair machine shops are a dying breed. Performance engines and large truck diesels are what keeps most of them going these days. Modern vehicles rarely have engines rebuilt even when they die. A secondhand unit is usually the repair option for that situation. Repair time is the main factor involved here. The more labor involved the higher the cost. it used to be that parts made up the majority of cost hence repair was the cheaper option.
As a military vehicle owner and enthusiast, it's almost comical to see how much care and precision you're putting into this old engine. I love watching the machine work but it's going to end up absolutely light years better than it ever was, even brand new. This is going to be the most precision F-Head ever!
Every time I watch one of your videos it makes me wish I had found a local shop like you guys to go the extra mile instead of slapping it back together with fresh bearings and calling it a day. Awesome work and attention to detail!
One of the most thorough and detailed balancing I have seen . I had no idea it was so complex to really balance an engine . Thank you , from Down Under
I was a mechanic for two summers in (75-76) High School and a Tank mechanic in the Army for 3 years. I studied all things automotive. Came across the term Balanced and Blueprinted I found out what Blueprinted is reading Smokey Yunick's book. But I never knew what balanced entailed until now. Thanks for the video.
I'm happy I've found your channel, I have some machining experience, but this is fun to watch... Thank you for allowing me to be able to watch... And the Cleaning Guy definatly needs a partial raise...
These guys do excellent work, I know because I do some of the same type work ! They don't hide anything, most machnist will hide tenths of and inch and claim they landed right on measurement. 1 to 2 tenths of and inch is some pretty good tolerances! These guys are very good at what they do.
Best Sunday morning television ever right here. I tell ya, that cleaning guy has some chops. It's like he's done this stuff a time or two.. 🤔 Also good to hear the culprit with the wrist pin getting into the cylinder wall.👌
Another excellent episode of The Cleaning Guy in Action!! Way to go, Jim and Nick!! Shops such as yours are becoming scarce and the two of you are doing a great service!
Use it as a post for a letterbox. I have seen a crank from a large engine used for the post and a connecting rod and piston with a cylinder sleeve used for the letterbox
You have created an absolute treasure trove in this YT channel! This video is, perhaps, the exemplar for clear, precise, and correct information for proper engine building.
Been a long time since I hung out at “Mike’s” when I was a lot younger. I refreshed my learning curve and seen some new balancing “tools” ! Thank You Men, nice quiet way to spend Mother’s Day afternoon. (Hey MaMa got a nap too 😃👍)
As an auto mechanic apprentice [late '60's] I learned that forged cranks ring clear & crisp, while forged [correction, Cast cranks] cranks ring kinda flat. And that's how it's been for all the engines that I have overhauled or rebuilt over the last 55 years or more. Your used Willys crank looks like a casting.
Yes, I thought that the replacement crank might be cast iron because it has a much narrower parting line than the original. The difference in "ring" might just be caused by the bolt on counterweights
The 3 machinist I know all shake like that. I think it's from a couple things. Working all the time, using the old machines, small tedious work. I look at it as a good machinist with lots and lots of experience. Love watching the videos. Keep them coming.
Thanks for sharing yalls talents and adventures. Ole Pops does a good job of explaining not just what he is doing but thw thought peocess behind why he would do it that way. Great job. Also the camera work and editing were spot on.
The bolt on counter weights will dampen the ring of the crank. I just wish you were closer to me, I would give you all my machine work. All the good shops in so cal have closed up. It's very refreshing watching professionals work.
JAMS, You guys are very talented. While watching I wonder the engineering that went into design, development of the machines you use. Very interesting and informative. It would be nice to see the engines running after assembly. Thanks, Boe
Very nice Jim! First time I have this process. I used to check our Allison C28 Turbine engines after OH and build up in our helicopters. Vibration is a component life ending happening. The manuafacture would not listen that they had a vibration until we brought vibration specialists in th the equation. You did a very nice job explaining and showing the process.
Love watching a master at work, the amount of equipment and knowledge in their use and goals, would love to use your shop for work and would be honored to work under your knowledge with a flair of humor thrown in 😊
Picky. Picky. Picky. But, if I were paying for the work, I'd pay it in a heartbeat. Precision. Precision. Precision. That is the motto of a great shop.
I would hope and pray that every machine shop takes the time and care that you guys do.i know your recording but you can tell the quality of your work and pride in what you do is second to none.i would be 100% confident the work would be the same recorded or not
Is it just me, or does this seem like amazing overkill for a 75HP engine? I love it. And as an old Jeep owner, I am sooooo jealous of whoever owns and is going to run this engine. Thanks so much for letting us see what goes into doing this. :)
You answered my question before I asked. When you were grinding the rod and cap ends I was thinking that will make the hole oblong. Glad I waited to comment.
Jim, your experience and understanding ,along with your articulation is truly helpful for those of us with substantially less experience. Thank you very much! Cheers
The last crank you checked out wouldn't have a ring even if it was new, because that crank is cast and not forged. I've always been told that the ringing test works on forged cranks and it's easy to tell them apart because a cast crank will have a very thin line on the rod throws from the molds used and a forged crank has a fairly wide grinding line where the extra material from the hammer forging has been removed. Somehow the first crank is a forged crank and the second one is a cast version. Possibly the earlier military jeeps used a forged crank and the later civilian units would use the cheaper cast ones.
You remind me so much of my deceased father-in-law. He was a machinist and had all the equipment in his garage. He would be thrilled at the newer computerized equipment to make things much closer.
I'm glad you show every step so people have an idea of how much time effort and knowledge it takes just to get ONE of many many tasks involved in building a motor correctly.
Excellent explanation AND showing of what it takes -- the what, when where, why, and how -- to balance the bottom end assembly; the entire process! She aught to be as smooth as an old Cadillac, Packard, or Rolls Straight-8!!!
Great video, the cleaning guy seems to have a knack for this machine work. Seriously though, true expert and great explanation of what you are doing each step of the way. My only regret is that you are too far from my area to give you any business. Both you and Nickolaus have a great work ethic and always a commitment to quality. I truly appreciate your candid discussion of being inside specs, demonstrating that nothing is ever "perfect". You always demonstrate a desire to get the end product as perfect as possible for your customer. Well Done!!!
Thanks for the detailed explanation of the steps &process ! You are VERY thorough! I think there’s not many shops of this quality left in this country !
1:25 I agree with the ringing of a solid crank and thud or rattle on a cracked crank. Is it possible the original is only a surface crack or a repair edge? Some weld shops have xray abilities. It might be worth it to save a "hard to find" crank.
Thank you the education you give is priceless. I have an engine builder just around the corner from me and I asked him if he needed help and I would love to work for him, but still no luck.
Thank you for the education! I’m an industrial balancer, and have always been perplexed by the process of balancing automotive cranks assemblies, pistons, etc. Fascinating!
I never thought that grams could make such a difference...I'm happy to see you guys take such care with customers parts, that you care enough, in this day and age
The cleaning guy appears to show a good aptitude for this line of work. I recommend he be promoted to the machine shop. Mind you mucking out pig sheds and scrubbing toilets is an honorable trade, but he's got a gift here!
We will keep that in mind! lol
Yeah, I got that same feeling...
Yea, seems to have a knack for machine work.
Definitely got a talent for both cleaning and machining! 👍🏻
Dont praise him too much or he will want a raise.....

One single hardware store washer!
Amazing how simple the solution to a complex problem can be.
I was always amazed that something that weighed hundreds of pounds could rotate at 3600 rpm and have a vibration of 2-4 mils.
Funny enough I test and balance rotors for GE. Even we use washers at the couplings to balance. Crazy what a couple grams can do to balance a 50 ton unit.
I love seeing a master doing what so many never even knew about. Thank you for all the memories.
I'm an old guy who never knew what I wanted to do for a living. After watching your videos I now realize what I was made for. (I was a FedEx guy until I retired in 2007) Next life I guess Thanks for your excellent work.
Unbelievable education! So much skill, patience, and attention to detail!

Let’s change that to “is” a great teacher. Now on TH-cam.
He’s a degreed mechanical engineer

Stoked to watch some more old school stuff. If I ever need machine work, I'm bringing it to you. You guys care about quality.
Thats a fact!
That crank grinder is a beautiful machine. I’m glad to see the cleaning guy takes good care of it.
He does keep it clean!
Real pleasure to watch a craftsman at work.Hopefully the younger generation will one day be as good.
Every time I watch one of your videos it makes me wish I had found a local shop like you guys to go the extra mile instead of slapping it back together with fresh bearings and calling it a day. Awesome work and attention to detail!
Cleaning guy, you are definitely from the old school. I believe you're the 1st person I've seen shut down a torch properly. Well done sir.
One of the most thorough and detailed balancing I have seen . I had no idea it was so complex to really balance an engine . Thank you , from Down Under

Thank you Jim , just one more great learning experience for me. Nothing better than watching you preform your magic on motors.
Abracadabra
I loved watching the rotating assembly balancing. Great content!!
Always love seeing the crank grinder in use. Such a cool piece of machinery.
I'm happy I've found your channel, I have some machining experience, but this is fun to watch... Thank you for allowing me to be able to watch... And the Cleaning Guy definatly needs a partial raise...
These guys do excellent work, I know because I do some of the same type work ! They don't hide anything, most machnist will hide tenths of and inch and claim they landed right on measurement. 1 to 2 tenths of and inch is some pretty good tolerances! These guys are very good at what they do.
I could watch you guys rebuild engines all day, something so satisfying about building something nicely.
Best Sunday morning television ever right here. I tell ya, that cleaning guy has some chops. It's like he's done this stuff a time or two.. 🤔 Also good to hear the culprit with the wrist pin getting into the cylinder wall.👌
I love it when the cleaning guy goes solo, he's a great teacher!
Cleaning guy is a national treasure!.....Sure wish you were closer to east coast. Got some EJ 25 heads that need him.
Another excellent episode of The Cleaning Guy in Action!! Way to go, Jim and Nick!! Shops such as yours are becoming scarce and the two of you are doing a great service!
Use it as a post for a letterbox.
I have seen a crank from a large engine used for the post and a connecting rod and piston with a cylinder sleeve used for the letterbox
Every episode there are always a couple pieces of experiential wisdom that the cleaning guy imparts.
Thanks again Jim!
Thanks for watching!!
It was nice visiting with you last week.
Really enjoy watching the cleaning guy do his thing with old engines.
Really enjoyed this comprehensive format. Amazing how much goes into these engine rebuilds 😊
I can’t get enough of these videos. Thanks for taking the time to make them and teaching us along the way. Fascinating.
I really enjoy watching true craftsman at work like this channel
Love watching the balancing act.. Ain't cheating..it's working SMART!!
THANK YOU for sharing your time with us!!
You have created an absolute treasure trove in this YT channel! This video is, perhaps, the exemplar for clear, precise, and correct information for proper engine building.
So educational to see a young guy workind down to a couple tenths that far between centers. He has a bright future ahead!
Usually a ring-the-bell test is done suspended to prevent damping from the support surface as well as the hand used to stabilize the crank.
What a pleasure to watch a Master at work.
You and Bob Ross have a soothing way of explaining what takes yrs to master. I could watch for hrs!❤
Been a long time since I hung out at “Mike’s” when I was a lot younger. I refreshed my learning curve and seen some new balancing “tools” ! Thank You Men, nice quiet way to spend Mother’s Day afternoon. (Hey MaMa got a nap too 😃👍)

And that's how it's been for all the engines that I have overhauled or rebuilt over the last 55 years or more. Your used Willys crank looks like a casting.
I think you wrote "forged" on both, which one rings clear and which one rings flat?
The Willys is actually a forged crank but the bolt on counterweights seem to dampen the sound.
That and weights are bolted on that would just kill the vibrations of the ring.
Yes, I thought that the replacement crank might be cast iron because it has a much narrower parting line than the original. The difference in "ring" might just be caused by the bolt on counterweights
@@JAMSIONLINE THAT is what I said when you did it. The bolted weights will not ring.
The 3 machinist I know all shake like that. I think it's from a couple things. Working all the time, using the old machines, small tedious work. I look at it as a good machinist with lots and lots of experience. Love watching the videos. Keep them coming.
I’m amazed. I wish you did the work on my first car (1937 Plymouth). Keep up the great work 😊
Thanks for sharing yalls talents and adventures. Ole Pops does a good job of explaining not just what he is doing but thw thought peocess behind why he would do it that way. Great job.
Also the camera work and editing were spot on.
So amazing to have these F Head videos. Just got my F Head 61 Willys running.
Nice! Been wanting to do one on the channel for a while.
I was always told a high ring in a crank meant it was forged vs a dull sound it would be a cast crank....
The bolt on counter weights will dampen the ring of the crank.
I just wish you were closer to me, I would give you all my machine work.
All the good shops in so cal have closed up.
It's very refreshing watching professionals work.
JAMS,
You guys are very talented.
While watching I wonder the engineering that went into design, development of the machines you use. Very interesting and informative.
It would be nice to see the engines running after assembly. Thanks, Boe
One of the best descriptions and view of what is being done as you go

Nice to watch a master machinist at work.
excellent meticulous craftsmanship ! Quality work ! One lucky customer !
A race ready rotating assy for an F engine? Now that's a first!!! Great job!!!!
Is it just me, or does this seem like amazing overkill for a 75HP engine?
I love it. And as an old Jeep owner, I am sooooo jealous of whoever owns and is going to run this engine. Thanks so much for letting us see what goes into doing this. :)
Wouldn’t dream of making fun of something you can’t help,you’re a clever man with only skills I could dream of having.keep it up 👍
You answered my question before I asked. When you were grinding the rod and cap ends I was thinking that will make the hole oblong. Glad I waited to comment.
Best video I ever saw you produce. WOW nice! /thank you so much!
He has so much old school knowledge combined with modern, its crazy. True craftsman and very very rare he is. Awesome to watch!
I'm Learning from a PhD in Machining! Just so impressive and great job!
Jim, your experience and understanding ,along with your articulation is truly helpful for those of us with substantially less experience. Thank you very much! Cheers

Patience is a virtue. Cleaning guy is very virtuous!!
Wow - totally cool to see you using that high tech stuff on a 70 year old motor!
The attention to detail and explanations of why the details are important make this channel simply amazing!
That balancing was very informative.
Love the attention to detail.
so nice to see the great detail you take in all the work you do ,,, AMAZING STUFF GUY,S
You remind me so much of my deceased father-in-law. He was a machinist and had all the equipment in his garage. He would be thrilled at the newer computerized equipment to make things much closer.
Learning so much! Thank you and please continue with the Willys F 134, certainly enjoying this series!
9:40
look at the cleaning guy using the flashlight on his hand held surveillance device 👏
When I was in Tech School 40 plus years ago, our instructor had us do the same thing when resizing rods.
I'm glad you show every step so people have an idea of how much time effort and knowledge it takes just to get ONE of many many tasks involved in building a motor correctly.
Excellent explanation AND showing of what it takes -- the what, when where, why, and how -- to balance the bottom end assembly; the entire process!
She aught to be as smooth as an old Cadillac, Packard, or Rolls Straight-8!!!
10:30 pm, Great skill with the technical work, I thoroughly enjoy viewing your videos, looking forward to the next episode of this series. Thank you 😊
Great video and Great work! Thanks for letting us watch!
That is a heck of a lot of work. And there is more to go. This is coming out far better than they would have done at the Willy's factory. Good job.
Great video, the cleaning guy seems to have a knack for this machine work. Seriously though, true expert and great explanation of what you are doing each step of the way.

Quality hour and a half. Felt like 10 minutes. Such a great watch. Thank you.
What a Master on this engine! The 75 horses will have a smooth run now!
Thank y'all for doing these shows, even though there are some real a-holes that would comment.
So cool watching an old school pro!! Thanks for the info!!
Wow ! Outstanding workmanship and attention to detail. Glad I found your video through a facebook friend
The depth of your knowledge is unbelievable ❤ thanks you for the time u spent making this video .❤
Really enjoy how you explain what you are doing
Thanks for the detailed explanation of the steps &process ! You are VERY thorough! I think there’s not many shops of this quality left in this country !
"Always think of the next guy, because the next guy may be you... " :)
1:25 I agree with the ringing of a solid crank and thud or rattle on a cracked crank. Is it possible the original is only a surface crack or a repair edge? Some weld shops have xray abilities. It might be worth it to save a "hard to find" crank.
Wow, what a great video! I wish I could be an apprentice in a shop like this. Learned so much!
You guys are so amazing! Real American precision craftsmen!!
Thanks so much for taking us through the magical things a proper machinist does.
Thank you the education you give is priceless. I have an engine builder just around the corner from me and I asked him if he needed help and I would love to work for him, but still no luck.

Dam lot more stuff tor me to understand. Glad you have the patience and knowledge to do this kind of work
Another interesting and informative video Jim. Your work is very precise. @1:04:23 I like your dog.
I never thought that grams could make such a difference...I'm happy to see you guys take such care with customers parts, that you care enough, in this day and age
Awesome machinery. The knowledge to use it all is even more impressive.
Yet another fascinating episode in the motor build for your old Jeep Jim.
It will be better than when it left the factory👍🏻👍🏻
