Did you have fun watching me get my butt kicked? ;-) That's how this job feels up until this point. Good grief! I forgot to mention in the video that if you harden and temper the threads on 4140 they are much less likely to gall. So commercially made 4140 threads would likely be better on many levels, being both rolled and heat treated. Maybe I should have bought those bolts after all... nah, I'm too cheap for that! Have a great weekend everybody!
Thanks for not giving up and pointing out the bright sides along the way. Really helps to keep me pushing through those impossible seeming tasks I seem to come up against so often.
Getting through the second half of my Friday at work used to be so difficult and tedious. Thankfully, I can now spend my lunchtime watching Jon suffer, and now my Friday afternoons seem joyful and carefree by comparison!
Holy crap, John. I don't know how others feel about the long form videos but, personally I love them. Thanks for taking us along for the ride. It's one thing to tackle these projects but a completely different thing to film edit and post in a manner that makes sense to the viewer. Cheers!
Well thank you for teaching us all the lessons you learned the hard way on Large Marge the Educational Excavator. That little Grizzly lathe has been putting in work! I would imagine if you’re pushing the tool to its very limit you would need to have the sharpest strongest inserts, stiffest bars etc to try to get the most rigidity out of the machine as possible. Easy for me to say as the guy who’s not paying. Glad you were able to salvage the part in the end. You’re awesome and definitely deserve a nice break after this job! 🎉 🍻
As always I appreciate the time it takes you to make and edit these videos for us. I also totally appreciate how long the video is, just over 1.5 hours! That's an hour and a half where I don't think about anything but what's going on in the video. I'm stress-free for over an hour. Hopefully that makes sense, lol. Hope you and the Mrs. are doing well, thank you again.
Hey Jon! Thanks for addressing everything I was worried about… I’m super relieved. Plus I learned a bunch about breaking strength and thread strength! Only about 10 mins in and already fascinated by the whole “bolt strength math” part! 😊
Jon, I would have taken quite a long time to come to the metal galling properties of the steel rod. Unless it breaks I don't see why you should ever have to take this component apart in the future. I look at this as preloading for the tracks. Thank you for such an excellent video with so much effort and work involved to repair the under carriage track tensioning device. I really enjoy your videos and certainly look forward to the ones you are going to make in the future. I certainly would not be capable of making the repairs you can make... Sam Clinton, Mississippi
Dude… that was AWESOME!! Good job! I have to admit I was lacking confidence in those 3 skinny metal bars of all-thread, but you proved me wrong! But I was right that the first one was never going to move again! Awesome video! Love it! Can’t wait to see LM put her shoes back on!
Awesome video brother! Large Marge is lucky to have you fixing her up! You are the best at teaching others in an educational way but also keeping it interesting and that’s why I and so many others love your channel. 👍👍
John I can tell you how we did it at the scrap yard back in the day. We would lay the spring in the steel bailer machine hopper next to the trap door, run the ram against it until compressed and then tighten the nut. Not really safe but, safest way we knew how !
The same thing happened to me with a Go Gauge. It's so frustrating. I did end up pulling the part out completely, clamping it in an ancient old vise, which was attached to a giant angle plate. Finally got it. Of course, the Go Gauge had to be recalibrated, but at least it was off. I feel your pain.
1:21:00 *is compressing a 50,000 pound steel spring about the size of a small person* Roof: *BANG*!!!! Jon: *heart attack* 😂😂😂🤣🤣🤣 God damn I can't stop laughing that is just the funniest shit I'm so sorry I feel bad 😂
It was a little surreal. What are the chances of all the days I'm ready to compress this spring that I have ice falling on the roof directly above me? Well, actually, given how this track adjuster project has been going, I guess the chances would be about 100%! ;-)
While I doubt I'll ever own an excavator > 10T I've thoroughly enjoyed this series. Ya have an impressive amount of time in on LM, you better use the hell outta her once she's work ready. All the best.
I did not know that about the 4140 either but always used never sieze on stainless. Good video though and well thought out. I'm with you on the penitrating oil. Doesn't do much before you break a rusted bolt loose. Heat just works better when you can use it.
Jon I saw an auto mechanic who would heat the rod and then put a crayon or candle wax on the threads then try to loosen the nut after wax had melted and seep into the rod . He had very good luck getting the stuck nut off.
Lots of stuff we learned the hard way, John please tell me in 59:00 (cranking on the lathe) that you had killed the power of the lathe... Seeing you cranking like that my eyes were on the red knob powering the lathe and imaging you slipping and turn it on...
For penetrating fluid, try going to the drugstore and get some Methyl Salicylate (Wintergreen Oil) we used to use it on aircraft when we had stuck bolts when I was in the Navy.
11:29 What you did that time was "idiotic", not yourself. You learned something from it and became better. Just don't repeat mistakes by expecting a different result ;) ;) In the process you made us all better by allowing us to learn. I appreciated so much that you don't edit out these parts GBY
That really sucks that that happened but stuff like that happened sometimes something like that happened to somebody else on the Internet where a $3000 nut got stuck on a $30,000 cylinder rod and he had to cut the nut off and make a new note and all that caused it was just a piece of swarf that got stuck in between the threads
Boy i knew this was going to happen... theses things are no jokes. Almost killed my father in law, went thru a concrete wall like it was butter. The springs were from a Komatsu PC100 i believe, alot smaller than large marge
It's funny how the commercial hits just as soon as you say you're an idiot. So we get to hear you call yourself an idiot twice!😅 smartest idiot I've ever seen.
Why couldn't you assemble the spring, the end-plates, the grease adjuster and the roller into the frame, THEN pin the tracks together, fill the adjuster to compress the spring and achieve the proper track tension? (Perhaps the spring's free length is longer than the frame allows for ...) ( or the adjuster travel is less than the 4 inches you need ?)
I'm not gonna lie...This was a bit of an emotional roller coaster for me... I looked like all the people watching Truman figure out how to get off the Truman Show...
How you project yourself, etc..., makes me very curious about your educational level and what was your job or profession before your podcast started...🤔🤓🧐..!!??? Subscriber and avid follower.👍👌. KeepOn...Keeping On..John..!!! Respectfully, , "THE O'L COCK "
Having grown up around construction equipment on the farm and as a career there is one thing I have learned. Anything under tension is NOT your friend. For what you will do with that machine you're wasting your time and overthinking for content.
I said to myself he is going to GALL the threads putting that on DRY ! Now cut the bar off bore out the old shaft and start over .The only way 50 years as a Machinist just start over did not have to watch the whole show .

Yup. I did the same thing once. Hand threading on and galled together permanently. 🥵
Experience is expensive
How come you couldn’t weld the stuck plate solid where it is and just use the opposite end as a nut and weld that when tight?
High on my list of reasons to to watch is seeing other people having the same kind of 'luck' I normally do. It's like a warm blanket to my soul.

An hour and a half video released from you just made my entire week.
I can't wait to get off work and watch this for the second time 😂😂
I LOVE these long-form videos. Thanks so much for posting these John, makes my day every time.
Pats for our boy Dozer! And thanks from all of us to Jen for letting you cater to the "Fix it Army" that created.
Hey Jon! Thanks for addressing everything I was worried about… I’m super relieved. Plus I learned a bunch about breaking strength and thread strength! Only about 10 mins in and already fascinated by the whole “bolt strength math” part! 😊
27:45 I always fill up with existential dread every time there's a warning of something painful about to happen...
Sorry. I figured after doing that edit that some people might think I was going to be injured. No, just my pride. But ouch!
It’s funny being on the Patreon and knowing what’s going to happen too. It made the tension that much greater 😬.
Hehe what @DMSparky said! 😂😅
Thanks for sharing the moments that count sediment!!
I like those recaps of yours. It's like watching a telenovela 🤗

Awesome video! Love it! Can’t wait to see LM put her shoes back on!
So much areas of machining got here. Ice from roof just got the tensioning more heart dropping.
I had no idea that there was so much work in maintaining these machines !! ..great job !!
That press is very nice, and simple!
Awesome video brother! Large Marge is lucky to have you fixing her up! You are the best at teaching others in an educational way but also keeping it interesting and that’s why I and so many others love your channel. 👍👍
Missed you last week John!!!!
I always love when I get a FarmCraft101 notification

😂😂😂🤣🤣🤣
God damn I can't stop laughing that is just the funniest shit I'm so sorry I feel bad 😂
The ice just wanted to make your day a little more interesting 🤣

Yeeeeah 🎉 it's friday evening and I was waiting for john's episode... tkx john!
I just looked it up and it looks like old johnny boy here has a post on practical machinist. Here's to the community for coming to your aid 😂
Great job 👍 thanks for sharing your on improving the Case!
If nothing else, it's really satisfying when it comes out like spagetti at 1:09:00 💪
Rough job with all those set backs, at least it was exciting for us to watch!
Just bought one of the thread guage's, always used bolts to check, the thread guage works so much better.
Man. So sorry u had to go through that. Live and learn i guess. LOVE the vids. Please keep them coming!
This sucker is right up there with that boat bolt
While I doubt I'll ever own an excavator > 10T I've thoroughly enjoyed this series. Ya have an impressive amount of time in on LM, you better use the hell outta her once she's work ready. All the best.
You got this John! Love your content! Go get'm tiger!
Next time when you're machining try to do that one effect where it looks the thing you machine is standing still while the tool moves, looks cool
I did not know that about the 4140 either but always used never sieze on stainless. Good video though and well thought out. I'm with you on the penitrating oil. Doesn't do much before you break a rusted bolt loose. Heat just works better when you can use it.

Looks like you got a lot after gall there John !

Key.words...
" ONLY 37 THOUSAND LBS. "
" I DON'T KNOW...I CAN'T DO THE MATH "
" IT'S FINE...AND I'M AN IDIOT "
Hi Jon, couldn't you leave the nut where it is and thread more on the other end?
Still love your videos, you've come to far :D
Every ice drop thud was intense on this side of the camera 😬
Ganna need a big ass coil Spring Compressor tool
How does the lathe know where the thread starts when you have to do multiple passes?
He showed it in the previous video.
That really sucks that that happened but stuff like that happened sometimes something like that happened to somebody else on the Internet where a $3000 nut got stuck on a $30,000 cylinder rod and he had to cut the nut off and make a new note and all that caused it was just a piece of swarf that got stuck in between the threads
Thanks!
Mad farming craft !!!
Question for you..
Was the breaker bar made in ina....😁😁
"Well if it keeps doing this, that'll be nice..... (snap) it didn't." ha! @1:06:38
I was going to watch a movie but I'll watch this instead
Are new spring assembly out of budget? May be cheaper and less painful.
If you keep playing with those springs you'll be the first youtuber in space. 😂
Wonder what would have happened if you would have tapped on it as you turned on it? I mean tapped on the face of the disc.
'O' Dear , Cuttus Interruptus !!!
Boy i knew this was going to happen... theses things are no jokes. Almost killed my father in law, went thru a concrete wall like it was butter. The springs were from a Komatsu PC100 i believe, alot smaller than large marge
i commented before watching, so...
Jon, Liquid Wrench is better than PB Blaster. FYI
I have said this so many times .The best Penetrating oil is Brake Fluid Bar None !
It's funny how the commercial hits just as soon as you say you're an idiot. So we get to hear you call yourself an idiot twice!😅 smartest idiot I've ever seen.
At least the swear box will pay for a night out Its call staying positive🤣😂🤣
Could you imagine what a shop would charge you to do all this work 😮. It’d be thousands alone in labor.
Oh great ...was expecting a video on seals and you "spring " this on us..........He said knowingly..
Safest way is to take it to a John Deere dealer. The one near me has a 50 ton press. They do this stuff.
π are not square. Cornbread are square, π are round.
Use a proper cutting oil instead of a friction enhancer like liquid sand. (anchor lube)
1:31:16 we don't grow up, just get older! :D
18:44 You make me nervous when you do that slow zoom-in because it feels ominous.
They are very easy to repair if you have all the right tools I fix them all the time at work
I whole heartedly agree on not getting a Darwin Award over this.
Talk about testicle retraction. Nope! Not me. Glad it worked out.
Why couldn't you assemble the spring, the end-plates, the grease adjuster and the roller into the frame, THEN pin the tracks together, fill the adjuster to compress the spring and achieve the proper track tension?
(Perhaps the spring's free length is longer than the frame allows for ...)
( or the adjuster travel is less than the 4 inches you need ?)
I don’t think anyone ever said tensioning these tracks was going to be easy… nothing on Marge is EVER “easy”! lol
I'm not gonna lie...This was a bit of an emotional roller coaster for me... I looked like all the people watching Truman figure out how to get off the Truman Show...
Hey Jon, I'm just curious: Are you a fan of the Red Green show?
I seen that coming you never cleaned the threads out you should have wiped all that anchor lube out I could see chips in it
The beginning recap is like ADHD/Hal From Malcom in the middle.
About 25:00, it looks in the video like your live center isn't running quite true. Maybe that's contributing to your chatter problems?
It looks like the more you make the more mishaps one tends to make, maybe there’s a relation between the two. Be careful please!
How you project yourself, etc..., makes me very curious about your educational level and what was your job or profession before your podcast started...🤔🤓🧐..!!??? Subscriber and avid follower.👍👌.
KeepOn...Keeping On..John..!!!
Respectfully, , "THE O'L COCK "
Thread gallin is caused by heat... Heating it up may not help you 😅
For me it's kinda obvious that spring won't compress anywhere near 3 inches
If I get to 3" I'm good.......🤣🤣☠☠
4140 4 letter words
or maybe donuts for a guy working in a nuclear reactor control room
Yeah, some " Farmer Fix ".........................Jay
You must have been watching Kurtis cee
Having grown up around construction equipment on the farm and as a career there is one thing I have learned. Anything under tension is NOT your friend. For what you will do with that machine you're wasting your time and overthinking for content.
I go slow as shit even with carbide.
👍👍😎✌️🤟😳😳😳
Did people actually say the springs would be easy to fix? I saw this job 2 videos ago and went "ungh, no."
finally!!!!
Don't be fooled it is not just 4140 that will do that.
i thought you're an engineer.
Beuno? Are you trying to co-opt a latin lathe operator? dohhh
I said to myself he is going to GALL the threads putting that on DRY !
Now cut the bar off bore out the old shaft and start over .The only way
50 years as a Machinist just start over did not have to watch the whole show .
Call your local dealer
If you get to 2" you'll be lucky
yah b7 !
