I love at the end how he says "All right, great, this thing is fixed", does a 180° on the excavator and rides into the sunset.
This comment made me laugh so much. Thank you
It needs to be a T-shirt!!!!
🤣🤣🤣
That really needs to be on a T-shirt!!
I watched this video a long time ago and I watched it again and read this before and thought no he didn’t and I watched till the end and yep he did lol
I am 60yrs old and I love watching you do the jobs you do. It reminds me when I was young and made it work whatever it was. Thanks really like your videos.
after i work on something, not even Andrew could fix it.
Bill Simmons lol.
Bill Simmons Shut up Bill! Go back to drinking your 40’s, you drunk.
A couple of suggestions you might find useful!
The bigger drill bits have a large “dead spot” in the middle, the chisel point, which does not cut. In harder materials a smaller pilot drill has less chisel so can drill instead of pushing through. Risk with a smaller drill if the work is not secured is breakage, and unfortunately smaller drill press tables can flex a lot. Plus side is if it is cutting properly, less force is needed. Once the pilot hole is through the larger drill opening the hole is using all of its cutting face, and again should cut easier.
The other suggestion is when using a tap, if you back it off every turn or so, say 1/4 turn back, chip break occurs and there is much less risk of binding up and breaking the tap
Love your work and thanks heaps for sharing!
Thanks, very good advice here.
In ideal situations I’d agree, however given the amount of flex in the drill press base and movement in the workpiece you’d end up with a broken drill bit in your hole, and a whole world of hurt! I would suggest chipping a drill bit that can easily be re-sharpened or not getting the final drill bit dead on centre are lower priorities here where accuracy of location is no so critical
@@AndrewCamarata Rather than drill and tap the cylinder ends you can get pins that have integral grease fittings and internal passages to get grease to the joint.
David Morse those pins are expensive...
NO.... NO.... NO.... NO!
I was taught this as a kid too, and it is blatantly wrong. Trust me I've been a Tool & Diemaker for 30 years. Do not go one turn forward then back it off to break the chip. Today's taps are made to crank right on thru. If the tap gets tight...then back up a couple of turns and then keep right on going. People please stop the back and forth motion with a tap. Drives me crazy.
I don’t think most would understand how envious I am of that ratcheting wrench.
Andrew is so smart. Goes ahead and fixes stuff without really knowing how, commenters with all the experience tell him the correct way. Now he knows the advanced skills.
When tapping threads best go 3 or 4 forward and 1 turn back. Good to clear the tap, swarf and threads !! Love the channel - Ken - Ireland 🍀☘️☘️☘️
I have that exact same tap set that Mom got me for Christmas in 1969 . I am now 64 years old . Some taps have been replaced but great quality . Snap on the case still there and works . Not bad for 51 years old .
So Glad you mention that wrench, that's a handy tool there. Thanks Andrew!
William Wallace Every tool has a hammer side!
As a little girl I loved working with my dad. Its so fun to see things get fixed.
That boss you just cut off is a grease fitting. The fitting uses a slide mechanism ( seen a lot in industrial equipment ) that slides over and is greased with an electric gang pump. Those were the very best types of fittings for impregnating grease to the joint.
Andrew , back in 17/18 when you were using the first small machines that you had, did you ever dream that in 2021 you would have the equipment and the business that you now have. Your drive and honesty has help you build a very nice company and home. I enjoy watching your videos
Hi Andrew. Love all of your videos. This one caused a discussion with my wife on what a grease fitting is. 😁We both watch you. It is getting hot here on the plains, and it is so nice to watch and learn with a cup of coffee. Thank you
I love how after you explain what your going to do you include us int the process by saying "let's get started."
Just want to thank you again and again for sharing all your expertise without an ego. Your videos are superlative and my favorites on all of UA-cam.
In my maintenance career I used a "Crescent Hammer" many times. First time I saw a Ratchet Hammer that was actually made to hammer. That looks like a real handy tool to have. I have a 1/4x3/8 drive shorty ratchet that really comes in handy. It's refreshing to see someone with real mechanical abilities.
Always a pleasure watching Andrew in prove on the equipment he owns.👍👍🇺🇸🇺🇸
Andrew, you must have a guardian angel sitting on your shoulders,...because no matter the technique you use in these repairs,..they ALWAYS seem to work out just fine. Good job done!
Great repair video Andrew! Great mechanical skills! The money you save on having equipment repaired must be huge.
Everytime I watch one of your videos, I learn something!!!!! Great Work!!
"All right let's get started" should some how be a theme with all your videos!
Considering you’re not a mechanic or a qualified fitter, you do somehow manage to get by, with your repair jobs. Many people here are giving you some excellent advice, with good intentions, that will make your repair jobs much easier and at times, much safer for you as well. I’m a qualified Fitter & Turner and of course l see you do things, that a trained and qualified person wouldn’t do. However that said, you’ll learn and get better as time goes by. I admire your tenacity to have a go at anything and you are a great inspiration and role model to many that watch and have subscribed to your channel, as l have. Keep up the good work Andrew. I thoroughly enjoy watching you work and Levi supervising.👍
l have learned so much from you, as you go about your many and varied jobs. Enjoy and be safe.
Brian, from Australia.🇦🇺🦘😄
I always have a huge smile when I see you accomplish stuff. Your videos are very informative and full of experience. Thank you!!!
There’s something about that Komatsu I just love. Probably my favourite excavator he’s got
I don’t understand why these videos get thumbs down...? I think they are great! Keep it up!
Thanks. Editing a pickup truck repair video now.
I laughed out loud when you put the grinder down and said "I wonder what that's for."
@@mmm365 I have no doubt that he'll weld it right back on if he finds himself needing it in the future.
@@CaptainJimNoss My fave is "Thats torqued to spec right there" after swinging out of a bolt with a breaker bar lol
yep :)
he'd make a great surgeon! cuts it off then says "i wonder what that's for"
Looks like the boss to counterbore and have a shielded grease fitting.
Worlds Shortest Book: "THINGS ANDREW CAMARATA IS AFRAID TO WORK ON"
Andrew: "Allraight this thing is fixed."
Also Andrew: "Turns the machine around exposing the giant hole in the side."
Andrew, When running a Tap there a rule of thumb that you should make counter clockwise turn for every few clockwise turns in order to cut off the metal that you turn up when cutting. I love your common sense, Andrew
John, your's is about the fourth comment mentioning breaking the swarf by reversing the tap. With fine threads like this, it is not so important as the build up is less likely to clog the flutes, and you'd feel the resistance and know when to stop. Truth be told, it will often be too late at that stage, and you'll damage the threads withdrawing the tap. I was more worried about how far he went in with a tapered tap, and if the grease fitting would bottom out before sealing, or even protrude and foul the pin. I suspect the metal was too thick for the latter, but you can see that the fitting was close to bottoming out. He did not need to tighten the grease fittings so much either, with them being tapered. BTW I speak as a retired engineer and toolmaker, who worked 40 years at Ford Research and Product Development in the UK. Andrew's approach to engineering is like that of a farmer. Taught through experience and necessity. My dad was a farmer, and could fix most things, but did not have the facilities Andrew has.
Sadly, I have now exhausted Andrew's videos after binge watching them since discovering them less than two weeks ago.
NO.... NO.... NO.... NO!
I was taught this as a kid too, and it is blatantly wrong. Trust me I've been a Tool & Diemaker for 30 years. Do not go one turn forward then back it off to break the chip.

This dude is awesome. Explains what's going on and gets it done plain and simple. Nothing fancy, just a guy fixing stuff. Keep rockin it bro. 😃👍
I love all your videos and as I said in the past I am a tool and die maker by trade, and I seen a comment to use a smaller drill first absolutely. And also I am a machine repair man and the other and on your hammer and ratchet ranch. You probably already know it's called a alignment pin. To align holes much easier. I love all your videos Andro you do a butt kicking job
the "pointy" end is the "spud" end...as in spud wrench...nice job bubba...I admire your work ethic...and your ability to tackle what needs to be done...you also have an exceptional imagination...
I like the wooden finish on that ratchet
Always maintain and take care of your equipment, and it will work for you and not let you down. good work Andrew.
Make the Komatsu Great Again!
Please give it a half decent paint job :-)
it was nice and teal when he first got it and he keeps everything else nice and clean. Its made me wonder how it always looks like its covered in grease.
edit: maybe half the paint flaked off and thats why it looks so bad.
Komatsu lives matter
I’d like to see that too!
@@mofoshizknack l
I would sure like to see that restored.
Andrew, you have every skid steer attachment known to man, and all sorts of cool machine tools to help your castle roof project, but watching this I think you would love what you could do with a mid sized milling machine. It would have made drilling those holes a total cinch, but it allows for very accurate hole placement as well as machining material to very accurate specs. You can get cutters, boring heads, collet sets etc. for next to nothing from wish bangood and aliexpress. I think you'd come up with all sorts of projects if you had one. You'd need a lathe as well I'm thinking. Also treat yourself to a can of RTD cutting fluid. It is waaaaay better than using engine oil. your taps will feel like they are brand new, and will last for ever.
While watching the video I thought, “Wow, I’ve never seen a spud wrench with a paint job like that”. I was gonna ask you if you painted it yourself, but then you explained. Always loved a good set of spuds.
A man of many talents well done mate enjoy all your videos 👍
the first video where the famous orange ratchet was born
Just as I was admiring that ratchet, you went and told me all about it. Heck Yeah!
That was so damn satisfying man, not a squeak out of it. Great work.
That's some hard metal. Good job my friend. I was trying to upsize some shear bolts on a 3 bottom plow just yesterday from 3/8 to 1/2" and ran into to hard alloy. Ended up saying some colorful words and welded the dang things with some 7018.Won't keep tripping now.
Cool, thank you for sharing your story
These machines need a coat of paint. Can't underestimate the PR value of nice clean equipment.
Maybe, I don't want too much PR value.
LOL Fair point.
Very nice job, Andrew. As always, thank you for sharing.
Its amazing how well those mini excavators dig
I love my spud ratchet! Thanks for the recommendation!
I like the look of that wrench. It's obviously metal, but it looks good with the wood grain paint or decal wrap.
I have a similar ratchet! Purchased mine some years back at TSC as well, but it was prior to the nice finish! Kinda funny, I have a nice selection of ratchets, but I keep going back to that one.
Wow you got the tools for every job !
NICE she's has no noise now 👍👏 good job my friend
Well done, nice bit of shearing on the old noggin too Andy, thanks.
Good job man this is one of your better ideas you should have thought of this a few years back on the front of that 4
Nice job Andrew! :)
The two above the offset cylinder should be for greasing the slewing ring. You can weld a small diamter piece of pipe on to encircle and protect the grease fitting. The piece you cut off could've been a tab to mount a rod protection shield on. Some had a little sheetmetal shield that bolted to the rod end and slid on a bracket on the barrel side. A negative rake drill bit or straight flute carbide bit is what you want for drilling hardened bushings. Also, the grease hole in the bushing doesn't have to be very big. 1/8" would be plenty. I've even used a dremel from inside the pin bore and cut a small slot in the bushing to allow the grease to pass from the fitting to the pin. An abrasive wheel will go through the hardened bushings much easier than a drill bit.
To The Top Crane very well explained
Great to see you here. What i meant the other night on your live stream was i appreciate that you have a family friendly channel and some channels are just out of hand. Keep up the great work
dropn loads, thank you! Hope to see you on my next livestream a week from Sunday!
Thanks, very good advice there.
Andrew Camarata, just trying to help. Please don't ever take any of my comments as criticism. You do an awesome job, and I admire your "get it done" attitude! 🙂👍
when using the Tap, Twist in one turn then back 1/2 turns then go forward 1 turn, Repeating the cycle until you are in. it is easier on the Tap clears the material from the cutting surface and produces a cleaner thread.
vxnova1 if you actually pay attention to the video while it’s 3x speed you can see him doing just that he’s also said that same thing in many of his videos and he also states that if it’s cutting smoothly (which it clearly was) you don’t have to back it off a partial turn and you can see in the video when it did start to get difficult THATS EXACTLY WHAT HE DID. Next time actually pay attention and check your facts before making a comment like that
NO.... NO.... NO.... NO!
I was taught this as a kid too, and it is blatantly wrong. Trust me I've been a Tool & Diemaker for 30 years. Do not go one turn forward then back it off to break the chip.

All that beast needs now is a good rattle can paint job lol. Awesome video!👍
I like watching your videos and I have learned a lot of different things from your videos ! keep them coming !
Another great video Andrew, I love this machine almost as much as the Yanmars, maybe one day I’ll catch up to the current video’s but I hope not. Your content is so much better than anything else
Andrew. I would still like to see a video on you doing a complete paint job on that excavator.
It seriously needs one. Please.
The first time I saw this excavator on your videos I thought you painted it that way on purpose. Then I saw you lovingly restored the appearance of your Yanmar and I knew that you would never make your equipment look like this on purpose. And it would be a very good educational video that you make for it. With the same quality that you do for all your videos.
As always, interesting and educational! Keep up the great work
Just amazing the stuff that you repair.
4:44 "I wonder what that was for" classic Andrewism love it!!!!
That threaded round thing on the cylinder you cut off is for a bolt for the guard thats missing for the cylinder ram, the slides are at the other end.
I had no idea they made these without grease fittings , how intelligent , they will sell more sleeves and pins and bushes.
You will notice with grease the machine will have more power and operate much better as well as with no squeeks.
Yeah, that's obvious now. It was always missing when I got the machine. That machine has "Oil impregnated bushings" that were not suppose to need to be greased. I guess after 4000 hours, they got squeaky.
Great job AC!
good job, brings back memories
Your vids are always enjoyable and inspiring, thank you. Some tractors have bucket pins with a zerk fitting on the end of the pin, so it's easy to grease. It would be great if those pins were available for replacing the old kind of pin, that grease from a hard to access housing around the pin.
Those pins could be drilled and grease fittings installed. I felt it was easier to install them in the cylinder though.
Hi Andrew. Always nice to spend someone else’s money! If doing many of these you would find it helpful to invest in some four facet carbide drill. Four facets avoid the drill centre chisel problem mentioned below and carbide is a lot tougher than high speed steel. Also I’d suggest a drill stop to avoid crashing into the opposing bearing surface. Easy thing to make. When drilling into a curved surface an end mill can help things start as it creates a flat surface so the drill tip does not skid around. Don’t drill deep with an end mill in a conventional drill chuck, it’s not safe, the mill will pull out. Still, you did the job, which is more than I could with the kit to hand. Stay safe. BobUK.
Great machine shop work without a machine shop. My knuckles look like yours whenever I do ANY project. Good job.
Another great video Andrew. Thanks for creating interesting content.
Komatsu equipment I’m familiar with uses a lot of oil impregnated bushings. Perhaps that would explain why there were no zerk fittings before you improved the machine.
Hello, Andrew.
The next time, when you want to add some grease nippels, it will be much easyer, to drill a hole right strait through the whole center of the bolts.
After that, drill some small holes at the outside of the bolts, just there, where you want, the grease comes out.
Have a nice day.
All the best to you, here from
Germany.
Very cool. Never thought to put a grease fitting into a joint.
Pins and bushes are probably smoked and packing with grease will only give temporary relief. If the bushing is deeply scored the pin will wobble on the arm, giving slop in your movements and causing more wear.
The Bushings are an interference fit, we use oxy to warm up, then hammer on a die or blank in the shape of the bush, depending on the machine and the degree of wear you may need to take the arm off to do this.
We sometimes use liquid nitrogen to cool 'em down to fit the new bush; its not as exotic as it sounds, quite cheap, just doesn't last long and will destroy the cooler you keep it in unless its purpose built to deal with the cold.
This is why you/we should always grease daily.
Hi Andrew,
I notice some things that you'd be wise to incorporate into your drilling and tapping.
When drilling and tapping my fluid of choice is called RAPID TAP. Machinists, in a famous machine shop in Victoria, B.C. who I learned so much from, turned me on to Rapid Tap in the 70's.
When you are cutting the threads, it is important to keep backing off the tap and blowing away the cuttings instead of chewing them all up in the process of going full steam ahead. You'll have a more perfectly or more optimally threaded boss that way. Obviously it isn't that critical for a grease fitting but elsewhere it does matter.
On one of your track machines I watched you drilling and tapping and wanted to suggest that you always start the tap by hand to insure perfect alignment with the hole before using your tapping drill to spin it in.
Cheers,
Cliff
Great Video Andrew !!! I was eyeing that multi tool ratchet i’m glad you put the description in the video information because I got to have one of them that would be so convenient to not have to bring the hammer and a punch and another ratchet.
Andrew take care yourself and remember those safety glasses getting hydraulic fluid in your eyes a bad thing 🤕
On a job I was on a few years ago running a loader, I had a hydraulic hose bust up near the bucket and sprayed me dead center on the right lens of my safety glasses.
Wow!
Wear eye protection everyone!
Like the video on the mini exc.
You did a good job Andrew......
Thank you Andrew .
You are the Mike Patey of heavy equipment
Of all of your tools, this is the one I wish I had. You should put an affiliate link in the description for that bad boy.
I'm waiting for the repaint. :)
Beau travail ! Good job!!!
Very informative video,thanks for sharing.
Love the videos man. I wish I could start my own company.
I think the ratchet is designed particularly for scaffolders, but it seems pretty good for mechanical stuff too, here in Europe they mostly retail between €60-€150 but this one from Cal Hawk Tools is around €41 in black, just have to spray paint it in some zany way, making sure I don't lose it!! Anyways thanks for the heads up and the video as I'm putting some new grease fittings on my old Ford tractor.
Yeah, the pointed end works well for lining up bolt holes. Spud ratchet, that one was really cheap.
@@AndrewCamarata Yes I noticed that too. I forgot to mention earlier that the ratchet was sold out and the same story on amazon.co.uk, and in France where I am situated, they did not even have it, I did find one on ebay.co.uk. Anyways, my ramblings here on just to say the power of the Camarata word has pushed all your followers to buy up all the stock!! ;-) Have a good weekend!
I like how your not scared to go for it and fix things yourself
Should have your cylinder to your left when drilling so if it catches it it does not turn into you . Great videos! Keep it up!
I would love to see some new bushings and inspection Videos :)
This reminds me of an old saying: "Grease or lube (depending on machine/application) well, work/function well and easily".
Andrew's videos are addictive...………..I love'm…………...
Now weld a pipe around it to protect it.
Yeah, I should, good idea.
With you Andrew there is always a way, you have broad vision. :-)
You should take one machine at a time and paint/fix miscellaneous issues. The construction videos are great but the repair ones are great too! Make a playlist for each machine. Camarata one color fleet or individual oem colors and we can't forget custom Camarata branding!
The thing you cut off is used to bolt the ram cover plate if your wondering 😉
You def want that plate to protect the cylinder
That creaking is a great sound for movies for opening large doors
ANDREW I've been watching your show now for awhile your a great worker and it seems that you've built yourself a great business But, please when it comes to drilling and tapping metal please always use oil. Next when you're working on your machines inside your garage for your health and safety install an exhaust in the garage to attache to the vehicles your working on and not inhale the exhaust fumes. Thanks Jerry M. be safe
Great job Andrew
One tip when drilling with larger size drill bit is to always drill a pilot hole. If you look at a drill bit you'll noticed a spot where there's no cutting edge, and that spot is the diameter you'll want your pilot hole. Also pecking when drilling helps break the chips and can increase the life span of your drill bits. And if you want to skip the pilot hole you can always get split point drill bits. Great work though
I use titanium pilot point bits that drill a pilot while also drinking the hole. Very easy to start and cuts well.
The bolt hole you cut off was most likely for a cylinder guard.
Oh dear.No gaurd fixing point.
Guards gets beaten up and damaged, and then people remove them. The under boom position of the cylinder is not ideal.
@TheJR1948 No, it stops the teeth of the bucket scraping up the cylinder.
I liked the video, but the simple wrench is a must.
