Finnishing up the Cat 235 project

The Bore welding and Line boring is finnished

[@w056007568]

I think that is a most impressive series of tasks completed very well and, in my view, quickly. I dread to think what the bill would have been if you had asked the dealer to carryout the repair! I'm amazed that he could carryout such repairs in the field, literally.

[@BrooksideFarmBarreMA]

$2500 for a week's work? Damn, that's a deal and a half! And looks like awesome work, too.

[@toddkratzer7953]

$2500.00 was a real bargain, that bill could have easily been double or 3 times that. I'm a retired machinist and have great respect for what he did out in the field. I never seen equipment like that before. Did everything go together as planned? The sound of the bearing being pressed in told me the interference was too much, hence the out of round bushing. I am impressed with his skills and he needs to charge more.

[@robm9860]

You got the deal of the day! He's old school charging old school prices. You should dance a happy jig on camera'

[@georgej7077]

Wow, thats a real bargain!! Tradesmen like that are worth their weight in gold.

[@trainman071]

2500 dollars for 39 hours that's a damn good price plus parts of course he did a excellent job

[@brian1326]

Used to put those bushing in, no press required, liquid nitrogen. No stress. This is an OK field repair but not what we did in the mining industry. We would have machined new ears, cut the old ones off welded on the new, lined bored and replaced the bushings. Probably would have cost 5K or better the way we did it. But when your in the field you do what you gotta do to get er running again.

[@copperheadmarine]

Well, That is partially true. It was being transferred from some place in Ohio to Morton where it would come on the regular truck to our dealer. The upgraded oversize pin and bushings was in Morton.

[@BlakeC94]

Just met this guy In Columbia, SC. This guy is die-hard for his profession.

[@michaelhaiden6718]

He'll you got a barging there not many like him around does not KZbin himself he is a journeyman does damn good work and knows his sheet seems like a good man

[@jcmathisiii6432]

That same job today would be how much Charlie......$7500 ?

[@screamingbull]

$2,500.00 was a very cheap price

[@trickcyclists]

It certainly was. I would have expected the thick end of a 100 an hour for that labour. The guy needs an agent :-)

[@Xlaxsauce]

yeah I could easily see 4k for the job

[@FlushtheSystem]

You get what you pay for. LMAO

[@perksweldingrepair4636]

I don't do line boring but I do some similar work in a lower income area and I charge 65$ an hour so he's definitely under charging... He needs to be at least 80$ but... When you do good work and your prices right and your overhead is low enough you can get the work

[@LittellFarms]

Damn that is pretty good pricing, how much has he gone up in 8 years

[@THOMASTHESAILOR]

That's not a reamer, it's a Hone.. You can Chrome plate the Bore of the new Dog bones, You mentioned .015 difference in the hole size.. You can hone it after Chrome, but, you can't bore it after that. Chrome is too hard. I like the Welder's Trailer, It's very similar to a Military Machinist trailer.. Up here in CT, That Job would have cost $4 - 5 K

[@daltonsequipment4419]

Wow reminds me of my father. Always undercharging for work. That should have been 5k on the low side.

[@anthonyedwards4423]

Absolutely! At least give the man a 15% tip like you would a waiter. Don’t starve the ox!

[@braykersixx6908]

Thanks for posting this. Very interesting to watch..

[@copperheadmarine]

Yeah, maybe a little over but maybe not. Didn't really look at the Cat invoices. Just kept getting bearings, pins and seals.

[@DruFishing]

Charlie, I know you can’t film on your big jobs per legal. But dang make a simple video once in a while when you’re in the shop or something, miss watching these, very few post this kind of content.

[@gangesexcavating]

Off goes the 235 for another bit of work. Yup job looks good. Worth $2500 everyday.

[@FlushtheSystem]

6:45 The bushings "crushed" ? No they warped out to egg shape. Between 8 to 13 thousands LMAO. Super cool the bearing sleeves in dry ice for 3 hours and push into sockets LOL

[@FlushtheSystem]

The joy of a cheap price is short lived in comparison to the sting and longevity of poor quality.

[@asvmanic]

The warehouse where that pin is at in Morton Illinois is about 30 minutes away from me lol

[@SGfabrication]

Glad you have the same problem with the bushings.I thought it was just me.Where do i buy a heavy duty reamer/ honer from.Really intresting video .Glad you bored then all out properly.Top work !!!

[@mojostevo]

Terrific, thank you.

[@charlietanner6211]

excellent work he is master craftsman neat rig he has

[@michaelhaiden6718]

He has a good thing going on there mobile machinist

[@anthonyedwards4423]

I remember watching this video several years ag and wondering why a machinist would have to hone a BEARING after boring the holes to the correct size. I am 68 years old and have been working in this same field for 47 years. Using a self made set up

[@anthonyedwards4423]

I get very accurate results. Also use a spring caliper with a 1 1/4” diameter adjusting nut which I measure with an outside micrometer without removing the boring bar. If I mike a 100 mm BEARING AND IT MIKES 8 thousandths over then that is how much press the hole should have on the BEARING SO THE HOLE SHOULD BE 3.937” or 100 mm all way through. If the hole is a couple of thousandths small, out of round or tapered then the hole should be honed true not the BEARING. And use SPRAY ON brand anti seize in the hole.

[@copperheadmarine]

He under bores it. Then hones it to fit, you can’t push it through the bore but if you bump it with your palm it goes through.

[@anthonyedwards4423]

You need around 8 thousandths grease clearance.

[@copperheadmarine]

Anthony Edwards no grease clearance on the bucket ears , the pin doesn’t rotate inside these. If I remember he wants 0.001”/0.003” clearance to keep from pin wollering in the bucket ears. This machine has dug 300,000 yards of dirt here and there is no pin play or side play between stick and bucket. The proof as they say is in the pudding.

[@FlushtheSystem]

Boom!

[@copperheadmarine]

I can. The disassembly was less than an hour.

[@cumminsman2007]

Well hate to be a critic Charlie, but that guy had the bore tapered that is why he was honing it out. I used to be a welder and machinist for Butler Machinery ( Caterpillar) in North Dakota I would never have done that. If you know what you are doing and everything is straight and true I was always less than a .0005 off my target bore size. Unless it was Caterpillars fault and had a screwed up bearing. ( I only sent one back to the plant in Peoria once I measured every one before installation) If that guy was a better machinist he would not have had to do the honing there a pin will clear with .001 pin bores aren't real critical like the ones on your dog bones but he is right there excess wear is a waste of putting a new pin in except when installed with bearings like what he pressed in he installed those really tight. How I know is I have spec'd out bores and pulled hundreds of bearing in .Cat specs them that tight on the boom and stick (.014) under bearing size is the tightest iv ever done never the bucket like he did that popping is tight taper in a bore which u don't want. This result in the bearing walking out of the bore prematurely 80hrs of Caterpillar failure analysis proved this to me its not bs. I was there machinist for many years and would be glad to inform you of whatever I'm a fan of yours that bearing should have been a .008 press max. Why this bore was tapered even I can tell you lack of bearings on his line boring bar number one and also did he cut the spreader bar he had welded on below after he welded the bores. If not that will definitely screw you every time cause the heat moves the ears also surface finish is major critical on bearings walking out of a bore.

[@copperheadmarine]

He said, that he pushed the bearings in and fitted them on the buckets? He did 2 buckets and had to hone both of them. He also told me he would have to hone them before he started. When he got done you could not push the pin through but you could bump it through. "not pound". He does all of Cats , Volvo's , Deere's and most other Dealers around here. Only cat does some of there own if they can not get him. all the pins that rotated in bushings fit fine. the bore he welded in the end of the boom where the stick meets was the same. You could not push the pin but you could bump it with your palm and it would go through. It may have had been tight but it was better than it was before LOL. it had a woe in it...It was woe out ha ha ha!

[@Linsey438]

Wyatt, lots of good info and it sounds like you know what your talking about. I have been reading a lot and have tried to find a good rule of thumb on what size to under cut your bore in order to have a press fit. I have been going with about .001 per inch of diameter. Does this sound about right? (Its been working for me)

[@cumminsman2007]

Doug you must not have a very good bearing set up or a good boaring bar because it would not have the spring to it and would cut a hell of a lot truer get climax bearings and 2" bar then you will not get much chatter and flex in your bar I also add bearings as close as I can get I kow it is a long span on excavators between them.

[@anthonyedwards4423]

Robbie Taber The factory bearings have the press fit made I on them. If it measures .008 over the inch or metric size then they want .008 press so bore the hole to standard size.

[@mercer767]

An easier way to put the bushing in place is to drop the bushing in liquid nitrogen. It will shrink the bushing enough to where it will slides in place and then it expand as it warms back up. i use to work in a landing gear repair shop and thats how we would put a repaired landing gear axels back into 767 and 757 landing gear. Nice repair for sure.

[@plateau2002]

If it was my 2500 dollars I would have performed the "acid" test of pinning everything up whilst he was still on site. Wouldn't you?

[@jerryking1434]

Soooo....you'd pay him to stand around and watch you reassemble your parts.. ???

[@scottpecora371]

$2553.00? I was thinking around $4000.00-4500.00 for everything I saw being done. Question: i noticed a satellite dish on his trailer, what's he use that for? Internet or entertainment?

[@josephrivett2493]

Excellent work. Impressive welding trailer unit, but- Am I the only one curious about the sattilite dish ?

[@markfryer9880]

+Joseph Rivett No, I was wondering about that myself. Does anyone have any thoughts about why he has one?

[@scowell]

Probably for the music.

[@brandysigmon9066]

Maybe for GPS, so order runners can find him if he is in the middle of nowhere when he orders parts. Maybe for tv when he stays overnight when far from home

[@repalmore]

I talked with the man and the area over the goose neck is a bed and the dish is for his TV. That's the way he can stay on sight working 12 to 14 hours a day. Not for me.

[@thomasbroking7943]

Wow thats unbelievable. .i would think a guy that skilled would be making minimum $100 hr..plus equipment charges. .great bargins..👍👍👍👍

[@osvaldorivero4242]

BRAVO !!!!!!!!!!!!!!!!!!!!!!!!!!

[@raysabin1820]

Very cool video ! I'm curious what the satellite dish was for on his welding trailer ? i didn't see a t.v. ,but I guess that doesn't mean it wasn't there :)

[@sisutrucks]

no problem paying bills when you know you pay for good work and not for people drinking coffee on your time. a buddy of mine once broke his wristwatch when banging his fist in the desk at the dealer after once again they had broke his truck more whe trying to fix it.

[@AllanSilva-iu1nv]

Can't believe he charges so chip. All that work he did, must be something wrong with that men lol

[@offgridwifey]

Hey, I have a question for you about a 1985 cat 235 serial prefix 64r... Having a hell of a time trying to locate or even name a part in the final drive. Any chance you could help? I have photos of the part in question. Thanks!

[@copperheadmarine]

K Tory I have the parts book, I can take pictures of page if you want

[@copperheadmarine]

K Tory you can text me a picture. 8438452090

[@deuce3485]

That sounds like a great price , cheap. I’m very impressed with his service trailer.

[@Graveltrucking]

For what you got done that is pretty cheap and you didn't have to truck the machine anywhere. So with all your pins and new bushings total job come out to 5000 dollars.

[@jamesworden1093]

2500 bucks , wow , what a deal

[@xaviertomasina4001]

very very very goooooooood

[@marklong2528]

high spots because to tight?

[@dougmills6398]

What is the brand name on the press that he used too press in the bushings?

[@danielthompson3119]

Doug Mills I seen another video with this same man and it was a enerpac

[@ChrisJB84]

Sweet job. Ya know, I like that fact that he had directv on his trailer lol!!! Im guessing for the music?

[@johnwallace7465]

What happened to you Charlie we miss all your cool videos.

[@boardingpass04]

That guy would make nothing but money where I'm from line boring on site is in heard of

[@kawscottyoung]

ifit shakes, I don't think it's gonna be from those bushings!!

[@richthecardude94]

Awesome how to type vid I don't have a cat but I have their boots for now lol

[@ltp1reno]

That's a lot of tools and skill for $2500 and the amount of work he did. The last machine shop i worked for got abou $500 per bushing to remove and replace back to factory bore. That guys is a real artist!

[@copperheadmarine]

ltp1reno he tells me he's got 99 problems but money ain't one of em;

[@FlushtheSystem]

Burnett welding south carolina. Got it!

[@jerryking1434]

Theres a lot of talent In those mashed up hands...

[@ricardoaparecidodefariaapa1769]

muito bom gostaria mt de ter uma oportunidade nesta area muito bom trabalho

[@copperheadmarine]

He makes nothing but money here LOL!

[@lordofbees9067]

look at his hands and eyes, from weldingg...

[@rogerstrand4903]

Expander pins work well too saves line boring

[@Qamarabbas-cc2xw]

I think that works cost 5000 dollars.

[@markfryer9880]

That drill he is using for the reamer is real old school, low rpm, alloy case, dont try to get a new one these days, well not without paying an arm and a leg for it.

[@brandysigmon9066]

Yeah the one he is using is an old one but will last forever, loads of torque too.

[@cat637d]

May I ask how many hours were on the machine?

[@TechniPat1958]

cheap

[@gangesexcavating]

Great porta power there. Slick.

[@aurelioalbertocantillorome9090]

quedó el diámetro cerrado esa no es la idea, habría q medir bien antes de realizar el desmontaje

[@bert26a]

Yup very interesting and a reasonable bill for all the work he did.

[@BryanBeast13]

Is this guy still around?

[@copperheadmarine]

Yes, sure is

[@Theonetwo48]

Any new videos here in the near future?

[@mojostevo]

Are you going to do a video of the reassembly?

[@nealk6387]

is that a cylinder hone?

[@jalenwalshak3598]

Hey Charlie do you still have ur old kenworth and cat excavators

[@DruFishing]

Jalenwalshak359 he’s got some nice modern machinery now search “Charlie’s machine sickness” on letsdig18’s channel

[@andrewnewton1526]

Charlie any new videos?

[@boardingpass04]

yeah 2500 really isnt a bad price either

[@nealk6387]

what type of bore gauge is he using?

[@grayswandir47]

Was a nice bit of kit. My dad was a tool and die maker and there was nothing like that in his tool box. Now he didn't set foot very far outside of a machine shop. The jig holding the boring bar would have made him cringe.

[@OOpSjm]

Neil Neil , standard bore gauge. You'll see them in engine shops for the king cylinder bores

[@douglaslodge8580]

1st Tell your guy bushing a bucket is the worst, build it up solid and bore to finish. 2nd buy a bore welder, I've heard all the bullshit about people that can weld faster by hand, they are wrong. You get superior welds with a bore welder and never a low spot. 3rd buy a climax line boring setup I own 2 of them my cutting rate is twice as fast as I'm doing all my cuts in 2 passes only, rough and finish. 4th the easiest way to install a bushing is to freeze it in liquid nitrogen then let it swell into the bore. It's good for a .003 interference fit and with it swelling your good for about an 80 ton bushing lock.

[@copperheadmarine]

Douglas Lodge it's loaded 150,000 yards of dirt since then and it's all still tight. It's good enough for me.

[@copperheadmarine]

if I remember he said the same about bushing the bucket but I said I wanted it how Cat made it and that was with bushings

[@douglaslodge8580]

Yes in some of the 200 series they did that so they cold move buckets to different machines but have since stopped doing it on the 300 series. Cat now recommends solid bores .

[@anthonyedwards4423]

Douglas Lodge your .003 press fit is wrong. There are a few Cat bearings that require .020 press for. Very few thankfully.

[@unibrowmonsterattack5527]

What is the inspection at 4:45? Runout?

[@brandysigmon9066]

He is making sure it is correct size for the pin, sometimes the bushings "shrink" after being pressed in. Evidently his did, that is why you see him honing / reaming it out later.

[@user-bk4gf7dg6i]

his favorite tool is the radio haha

[@constitutionalUSA]

Lotsa Ford trucks there........ Leave the Chevys for the pretty boys

[@FlushtheSystem]

I'll just grind away 500 hrs of the life span of those sleeves LMAO. GOOD DEAL REPAIR

[@FlushtheSystem]

6:51 Now we will grind away your brand new bushing sleeves. Good Work LOL

[@brentking-gmailking2570]

Wow, that seems to be a great price. I know it will be worth the money. Thanks for sharing and have a great day.

[@I_leave_mean_comments]

That's actually super reasonable for that job. Where are you located? Here in Philadelphia, you'd probably have to pay twice that to get the same job done.
