@@CuttingEdgeEngineering I would have used a sealed bearing to replace the bad one, rather than another shielded bearing. I bet that black belt dust got down into the bearing and that's why it's bad; because a shielded bearing is not quite as closed up as a sealed bearing.
@@ronsilvester2944 There is no reason not to have a sealed bearing.. He just replaced it with the same one, rather than upgrading it. But it's fine: he can change it again later..

I've been a maintenance mechanic, machinist, CNC repairman and electrician for almost 50 years. I appreciate all your skill Curtis. You can work on my crew or I will work for you any day. You are truly a dying breed.
It's a heck of a lot cheaper to replace some bearings then it is to repair the excess damage done to other parts because of the bearing failing. Timing is always the problem - you don't want to jump on it too fast when it's still working fine, but if you wait for it to completely fail you risk damage to other parts. Great video!
In 1966 I was 13 yrs of age when I didn't know what to do with my future. My neighbor took me with him to the electrotechnical company where he was head mechanic of the department for rebuilding electric motors. It was the time factories had a 2 week summer standstill for servicing all the motors. From 0.75 kW to 200 kW. So it was busy in the shop and in no time I was busy taking electric motors and the attached gearboxes apart, cleaning them, renewing bearings etc. They taught me every thing about electric motors. I wasn't even legally allowed to work! I saw it just as a thing to be busy during summer holidays. When I had to go back to school he came to me and gave me the pay of a mechanic for those weeks. He told me I earned every cent of it. The next year I worked there too during vacation. After that vacation I entered the practicum for electrotechnical engineering at school for the first time and the teacher asked me what I thought of the it. I pointed out to him all the different types of motors he had there with all the specialties of them. He got a bit pale around his nose and told me he had 2 years to to teach me what I already knew. You brought me back to those years... thanks!
@@CuttingEdgeEngineering Not to mention that failing bearing(s) would eventually screw cutting accuracy all to Hell and back making it that much harder to machine parts to proper size for your customers...
@@CuttingEdgeEngineering Well, guarantee the grease you put back was a lot more quality than the original, and you probably got all of the grit from the original casting out as well. Had that, take it apart for service and chunks of the sand from the casting was still in there, right next to the 1S bearings that were noisy. Sand all got moved, cleaned, and the new 2RS bearings went, in minus the one side seal, so the oil fitting could still work. then it got a nice fill of synthetic oil to make them happy. Original was something akin to road tar mixed with gravel....
I'm blown away that you can take apart that many parts and remember where they all go when you put it back together. I'm sure I'd have three or four screws, etc. sitting there and I'd have no idea where they went. Impressive.
Planning and preparation are key. I use a few muffin trays and label them as I go. Everyone has a process, but I guarantee he is very organized with every part he pulls off. Not to mention, he has a video of him removing it so assembly is easy.

Do you EVER look back over the video to have to remember where a screw or a bolt or anything has to go? If not, then you are really impressive at remembering pieces and parts! Impressive!!
OMG, that was excruciating, watching the amount of time and effort to break down, and it only makes sense to replace all the bearings while you got it apart. On the other hand, I had to chuckle at Kurtis the "Drifter" using the shift knob, and Homey is always a joy to watch. But the image during the outtakes of Kurtis the "drover" riding the mill had me rolling! Yee Haw, giddup! You go Kurtis, Karen, and Homeless!🤣👍
I would be ABSOLUTELY NERVOUS AS HELL to disassemble a machine like that in fear that it would NOT go back together correctly! BRAVO, a job well done!!
As an HVAC service tech, I appreciated seeing what preventative maintenance looks like on your machinery. I love doing maintenance when it's planned because you have the flexibility to be thorough and nothing critical is waiting for you to finish the work.
I'm a buildings utility engineer and the number of clients that want redundancies and never failing systems is large, but they seemingly never want to pay, what it takes to actually build redundant systems that can fulfill their demands. 😂 Want 10 walk in freezers that are totally independent and survive a power outage of 1 day? Get ready have 10 condenser units on the roof and an emergency generator in the basement.
@@JainZar1 Probably not you, but a lot of people would be surprised how many 70% efficiency rooftop gaspacks there are still in use. They've all been repaired enough times that it would have been cheaper to rent a crane and replace them all at once, but property managers and owners would rather be penny wise and pound foolish.
@@JainZar1 and then they want efficiency then complain when the condenser is "too big", then they don't want to ever clean them or pay for them to be cleaned!
I’ve said it before and I’ll say it again. Video and especially editing are superb. The professional presentation in this video made a 42 minute video seem like 15 minutes. And I have no need to skip through any segments because you do that for me.
@@CuttingEdgeEngineering Do you have to consult the video when putting certain pieces back together? Or do you have a 'system' to how you lay out the parts? Or do you just have an excellent memory?
@@d.jensen5153 I'm wondering the same thing... I'm good at tearing things apart but yeah, I always end up with an extra screw (or three) loose! Or maybe they were to start with and THAT's the problem?! 🤣
I admire that you can just tear into your mill, fix it, put it back together (without a tin of leftover mystery parts) and get back to work. Good stuff.
I was thinking the same thing, start first thing in the morning and have it all torn apart, lunchtime run and get the bearing you need and food, second half of the day is putting it back together and boom ready for the next day. Wish I was that we'll organized an had the time i would need to be able to pull off something like that.
I really appreciate the moments it appears you had a memory dump and your face goes blank and you stare at Karen. The laugh you both share immediately after is so heart warming to see you guys laughing and joking to try to recover. You two and Homeless are so endearing that is why we love you so much. You are a skilled machinist and have so much passion it is contagious! Thank you for a friendly fun and informative start to my day early morning in Alabama USA. Take care and keep up the good work we love to share your day!
Surprisingly, it looks like no one has yet asked to see or hear more about the drift car! Therefore, I will do so. Another wonderful Friday video. We watched it while enjoying our cocktails, as usual. Tearing into a milling machine takes a lot of knowledge and courage. Glad it worked out. Worn out bearings can lead to nasty problems. Thanks, Kurtis, Karen und Homey, from Bruce, Karin, Halgrim and Bella in Germany.
What a great reminder of a job I did myself about fifteen years ago. "The same bearing sound" isn't a bad thing, and it's always good to begin again with new bearings and an actual installation date recorded. We easily forget the time and frustration of doing so with the years of no trouble that come after.
I think it still definitely sounds better, a lot of the bearings sounded very tired. Also, as others have said, I absolutely love the banter in the bloopers you two have. Great work both of you and thank you for sharing!
The outtakes are almost my favorite part of all the videos. It’s funny how some people want to call you out for using your tools a certain way. They are your tools and you can do whatever you see fit, with your tools. Thanks for sharing your knowledge and time.
G’day Kurtis,Karen & Homeless, thanks a lot for another year of the best machining, welding, problem solving, filming/editing and ripping the crap out of rubber toys anywhere on TH-cam. Have a great Christmas and please come back next year. Many thanks to the CEE Team. 🇦🇺🇦🇺
Liked before I even watched it! I spent a large part of my career as a Mechanical Engineer (now retired) dealing with bearings and I can say without fear of contradiction that the sound of a failing (or failed) bearing to me is right up there with the sound of fingernails on a chalkboard! 😱
Nice to see the "bearing installer tool" of a socket n mallet is of common use as when I started had the old guys look at me like I was crazy.... if it works, well then it works!
I legit laughed for a bit when I saw that. Here is this channel where some dude is engaging in some very precision stuff on large heavy objects. He's whipped out tools and tricks I've never seen before more times then I can count. I couldn't even imagine how much money he has invested in tools and equipment. So when I saw him using a socket as a bearing installation tool like I do at home..... well I just found it awesomely relatable and funny.
@@MrUltraworld If I'm not mistaken it's a Nissan S15 200SX (Silvia) so SR20DET which is Nissan speak for 4cyl, 2.0L, two cams and a single turbo hanging off the side.
Kurtis has bigger and more balls than a herd of bulls to take something like that apart with so many parts and no instructions. Then to put it back together like he had done it a hundred times. More than just hats off to him.
and well lubricated...was cringing on the first bearings he put in, then he fired a few shots of oil and I was like "YES!!!" Plus all that white lithium grease he put in on the gears and sliding parts, left a smile on my face...cleaned, and restored and well protected for many years of awesome service!
My dad was a WW2 aircraft mechanic and one thing he impressed on us when working on the farm equipment was to always use something else between the hammer and the bearing. For bearings up to 2 1/2 bananas (63.5 mm) we would use a socket that fit over the bearing race. For really large bearings we would use a block of wood in place of the socket. And that little "pop" when pulling using a gear puller is always so satisfying.
Hafco have evidently put some very nice effort into building a quality milling machine as evidenced by the overall build quality you uncovered as well as nice details like balancing gears that they could arguably have gotten by with if they'd left imbalances few would notice. But you also added significant value to your own machine by installing better suited-to- purpose sealed ball bearing assemblies, by using polymer composite grease in the main gear case and by scribing the precision visual guideline as a visual rotational axis cross-check. Hafco cut (or spec'd) that top drive gear set "off the involute" to give it more robustness at the expense of gear noise. This also let them specify harder (but more brittle) gears there for better long-term wear characteristics also at the expense of noise. But the machine sure sounds sweeter than it did, and I'm confident you postponed any major maintenance on that machine by hundreds, if not a few thousand, operating hours. As an old manufacturing consultant, you're a joy to watch on the shop floor. Your success as a machinist is as well-earned as your, Homeless' and Karen's work in TH-cam production.
BRILLIANT as usual!!! Karen's editing is first class, I can't count how many times my friends would repair something, sometimes expensive machines, and not bother to clean it going back... as always, you set the standard for a "Job Well Done!!!"
I do appreciate you giving sub-titles for the dimensions. I am a yank and are still trying to learn, and convert to the metric system. As a cabinet maker, all of my hardware is metric. When you have used the American system of measure for more than 50 years, metric is a challenge. Love your videos! Keep up the great work.
The practical skills you display are second to none! My absolute favourite youtube channel.Many of my non engineering friends now hooked on the team of three from down under. Half a million subscribers in 2023 no doubt about that!
Yes, this is something I'd be scared to do. Taking complex equipment apart like this would make me highly nervous about being able to get it back together again. Curtis is braver than I am! A *LOT* braver.
He has a Secret Weapon... Karen is filming everything he does so if he can't remember where a part goes, all he has to do is watch the video of him taking it apart...
Have confidence in yourself, switch the negative thoughts off. It is a series of small jobs that make a complete job, take your time, one step at a time. Having experience obviously helps. But in my experience it always works out no matter how deep a hole you are in.
What a LEGEND !!! Finds smallest fail in the system bearings - changes everything to new. Getting new machine effect right after and long after the maintenance is done
It's a VS drive head, no matter the brand or where it's made they all have rattles, just turn the radio up a notch and fugitaboutit. Loved the PSA on 123 blocks, people would stroke out if they knew that 123 blocks are on the list of "consumables" in my shop😜
Gooooood Evening Queensland....... another fine video for our Viewing Enjoyment...... Cheers from around the World from all your Fans.... Just can not get enough of your fantastic work...... Best Wishes from the Other 'Sunshine State' Paul
One of the best videos I've seen so far! It's probably also because I'm a mechanical engineer myself. And then again these cool outtakes that always have tears in my eyes. I wish you both a Merry Christmas and a Happy 2023! Stay healthy! Greetings from the wet and cold (-7 degrees) Bocholt (Germany)
As my dad used to say whenever the car developed another strange sound... Turn the radio up another notch son.. Worked every time ;) Thx for fun video :)
Before you pulled it apart I had it pegged as gear noise (just because of the rattle)but a new set of bearings won't hurt. Once again interesting, This is the type of work I did for 50 years, Cheers Billo
Usually I'm always left with a bolt or two after putting things back together. It's great that you have video for reference if you don't remember how to put something back.
15:59 I said “YAY” in my head when that came right out. Having pulled bearings with hack a tool in the past I appreciate your assortment and now that I have a lil bit of money I have bought my needed tools too….Gotta love the right tool for the job.
Nice job, well done. Loved your take on the 1 2 3 blocks, probably saved about 50 negative comments! They are handy though, use em all the time in the woodshop
@@CuttingEdgeEngineering She's a wise woman! You putting that part in made me laugh because, as @mikeweagle5523 demonstrated, well, I'll just say, it was wise and not get myself into trouble with commentary! 🤣
I’d like to say how much I appreciate the quality of editing that goes into your videos. You do great machine work and it is showcased well by skipping over the more tedious parts and emphasizing the points of action.
As soon as I saw the gears I knew you were never going to be able to make it quiet for very long. My old Van Norman mill has a 3 speed box with straight cut gears and there isn’t an oil on the planet with a heavy enough weight to keep it from howling. Great video! I have Mill envy!
Nothing better than a new CEE video with a hot cuppa after removing 4" of heartattack snow off the driveway.... Merry Christmas from Canada, thanks for all the great videos this year!
I like the way you treat your machines. You treat them like buddies. When you need them they sure will treat you back like buddies. For a one man workshop I can see your passions in the trade. Thanks for your encouragement!
Awesome work as usual bud, I spotted that mugen handle on the quill yonks ago and always wondered if you had a history with cars. You handled this job the same way I would have done and it was a pleasure to watch, can’t help but think if this was done on one of the American machining channels it would be drawn out into a 12 part series and take 18 months to complete 😅
I don’t watch that American channel anymore because of that. Kurtis just gets right in about the jobs, no fucking about. Problems are solved, not glorified. Job done. Next. Cheers mate, all the best.
That machine is really served you well first time you've ever done any maintenance on it in 5 years money will spent. I am really surprised they didn't steal that machine up better than that. Stay safe and enjoy the weekend see you on the next one.
Great video, lots of information. That "control box" on the side of the motor is called a pot head or pecker head in my neck of the woods. I have no idea of why but I heard it at my first mining job as an electrician back in 1969 or 1970. I used to repair variable speed gearboxes that used the same Reed style sheaves and belts. My wood lathe uses the same setup today. They work great so why not continue to use them. The ones I worked on had two grub screws per threaded hole to make sure they didn't come loose. Have a great weekend, jack
Well...those two dry bearings and the two that seemed to have bad spots, definitely was a good idea to replace em...they more than likely wouldn't have made it too terribly much longer...prevented a catastrophic failure with a seized bearing! Good stuff...love how Karen jumped when you yelled BANG when you flipped the power switch...LOL! Keep em coming!!!!
I caught myself trying to tell you through the screen, that noise is mainly from gears not bearings. But as you pointed out, it never hurts to replace bearings and clean up every now and then.
Preventative maintenance can seem like a bit of waste of time but if definitely isn't. If it was done more often maybe your shop would be a little less busy!😉 Happy Friday - Thankyou K, K & H 👍
Absolutely fascinating to watch someone who knows what they're doing take apart something they're not familiar with and then put it all back together again with no leftover parts. Well done. I know through the magic of editing this didn't take very long but if I might ask, how long did this process take?
@@CuttingEdgeEngineering Did having the video come in handy for figuring out where some parts went? I often take video (and always pictures) when disassembling something unfamiliar to make it possible to find where things go if I lose track.
Yep. As I sat here watching, knowing that if I tried this, the odds of getting it back together in working order if it was me, would be precisely zero. I'm remembering the time I took apart a much simpler tool, then put it together, only to find parts laying on the bench underneath I had forgotten. Taking it apart and then back together the second time did go faster. :)
@@agentx7138 He did find multiple bad bearings and was able to clean and degrease/re-grease everything. Preventative maintenance. Now instead of it failing when he has jobs to do it will keep working.
I used to be a maintenance fitter at International Harvester back in the 70's and did the same type of work. Really enjoyed the video brought back memories.
I love the machine explanations and fixing videos along with all the other ones. Thnx for taking the time to share the fix . Cheers from Vancouver Island BC Canada.
As always... loved the video. you're a brave man pulling that all apart yourself but I imagine that saved a boatload of money doing it yourself. The "BANG" @42:03 and accompanying camera jump was effing hilarious! Thanks for the laugh!
So awesome to have this on video. Not only for reassembly for yourself if you needed it, but will probably end up being an invaluable resource for someone else somewhere in the world. Keep making chips!!
Curtis, as much as I love your various videos of you repairing other people's equipment, I have to say there's something surprisingly satisfying about watching you do a shop infrastructure video... especially seeing and hearing the finished product... absolutely beautiful. Best wishes to you, Karen, and Homie in the holiday season and in the new year!
The company I worked for had large bench drills. They had large gearboxes flooded with oil, they made identical sounds. I thought it was normal from the beginning too, until someone pointed it out in the comments. The milling machines had helical gears and only the motor could be heard. Greetings from Poland and sorry for the language is Google Translator. :)
Some lads that worked for a few bearing companies told me to chill bearings with dry ice and alcohol if you can't get a hold of liquid nitrogen. Worked a treat on some Subaru wheel bearings. Cheers Love your work
Those 3 prong bearing pullers I always found it troublesome to keep the prongs separated wile I tighten down the screw. I found if I put a piece of shop rag between the prongs it gives it enough resistance/springiness to keep them apart till the screw is tight. Especially when it’s horizontal and not vertical. Then it’s easy enough to pull the rag out once it’s tight. A tip I found works really well. Maybe someone else out there can use it.
Maintenance, the unsung hero of every company. How on earth did you keep track of all of those parts? You could do a whole video on that. Again, Karen's video skills were excellent. As for me, I was impressed that not once did I hear you say, "Karen, hand me that wrench.".
Always recall the forklift driver who left the company and got a new job. However one of his key jobs was greasing the machines in the morning. 2 months after he left there was 100k of scrap produced when the fixtures became worn…..
@@ellieprice363 That's how they do it in old car restorations. Tag, bag and photograph. With phones these days it's a lot easier than it used to be. For car restorations, the rebuild can take years. Nobody remembers what goes where.
I just love those satisfying clicks the bolts make when they come undone. The filming quality and timing just gets better and better over time and it's so amazing to see!
When you got deep into the disassembly it started getting quite complex and involved. I'm glad you managed to get it all sorted out with no issues. The design of the mechanical speed control was interesting.
One might think that split pully enabling the variable speed is a new innovation but it's rather old. I have a 1964 john deere garden tractor I rebuilt and it has that design to give a range of speed for each gear
@@maggs131 Yes, it's been around for years and years. The new CVT car gearboxes use exactly this principle but with a steel drive belt...and are unreliable.
I'm rather impressed with the overall engineered design of this machine, especially the bearing carrier. Makes it a LOT easier to service. There are too many other modern machines not well designed for servicing. Neat vid, thanks for posting!
It is NICE to see relatively new equipment well made from the outset that's maintainable too. In the past, made to last and be maintainable was the norm. There is far too much planned obsolescence currently.
Another awesome video James! What would be really cool in my opinion is if you had a little timer on the bottom right or left that gives the actual amount of time you've spent to get to whatever point you're showing in the video. That would allow people to see a realistic guage of time spent on each project. Keep up the great work!
Great videos!! You are very methodical and thorough. You were right in replacing those bearings. From my experience the 2nd source of noise is the backlash in the gears. You may want to check them and see how much out of spec they are. I replaced the bearings in a Bridgeport and had the same thing happening quieter but still loud. I then check the clearances on the gears themselves and they were way out of spec. I had a frien that had a brand new head that was damaged in shipping years ago and offered them to me. We got them off I replaced them with the newer ones given to me. It was a very quiet mill! Success was sweet.
As a tip, in the future if you need to rebuild the head of them. Just take the four bolts loose that hold the head to the ram assembly. We had a few machines go out for rebuilds at the shop I used to work at, and that is the beauty of bridgeport style heads. Four bolts, and you can take them off. If you want them mounted vertically, just set up an angle plate on a bench and you can keep it vertical. While obviously this is hindsight for you, it is something to remember in the future in case you need to pull the head off again.
@@pawz007the tip is he didn’t need to remove the ram just remove the 4 bolts holding the head to the ram , the 4 bolts in the front, and leave the ram on the base.
Good Morning CEE; Great video this week. Kurtis you are amazing. I would have never tried to tear down a critical piece of equipment that complex. Well worth the effort given the number of bearings you found going wrong. Thanks from Halifax, Canada Have a great Christmas.
Maybe there's some Halifax hashish in the hamburgers? It's really not much complex. Like Kurtis says, follow ya nose and keep at it, sorta thing. You can do it to Mr. Weagle. Keeping the parts where you want them is always helpful. Like taking video of the procedure while tearing it down and paying attention to how it's constructed .
I love seeing someone who really knows what he's doing, working with big machines and creating stuff of exceptional quality. Makes my shop look like crap, but there you go!
Super nice video, with great closeup shots, and provided knowledgeable information throughout the teardown and reassembly, my sincere thanks to both you and your wife for an extremely well-produced video.

On the other hand, I had to chuckle at Kurtis the "Drifter" using the shift knob, and Homey is always a joy to watch. But the image during the outtakes of Kurtis the "drover" riding the mill had me rolling! Yee Haw, giddup! You go Kurtis, Karen, and Homeless!🤣👍
haha glad you enjoyed it mate, thanks for watching
I'm not an engineer, but love watching what you do. The camera work and editing is very good, so no boring bits to fast forward through.👍
Wow, thanks!
I agree with you, if it’s going to be boring Karen fast forward’s for me. I appreciate that. Thank You sir & ma’am Very good video as usual
The boring bits are in another video.....
Dude… I’m a nurse and I can’t get enough. Even my 4 year old loves watching this guy!
I would be ABSOLUTELY NERVOUS AS HELL to disassemble a machine like that in fear that it would NOT go back together correctly! BRAVO, a job well done!!
The mark of a true professional to make something quite complex look easy.
As an HVAC service tech, I appreciated seeing what preventative maintenance looks like on your machinery. I love doing maintenance when it's planned because you have the flexibility to be thorough and nothing critical is waiting for you to finish the work.
I'm a buildings utility engineer and the number of clients that want redundancies and never failing systems is large, but they seemingly never want to pay, what it takes to actually build redundant systems that can fulfill their demands. 😂
Want 10 walk in freezers that are totally independent and survive a power outage of 1 day? Get ready have 10 condenser units on the roof and an emergency generator in the basement.
@@JainZar1 Probably not you, but a lot of people would be surprised how many 70% efficiency rooftop gaspacks there are still in use. They've all been repaired enough times that it would have been cheaper to rent a crane and replace them all at once, but property managers and owners would rather be penny wise and pound foolish.
@@ethankriegel5957 True, a project I am currently working on is replacing a bunch of R-404A freezers with ones using R-744/CO2 as refrigerant.
@@JainZar1 and then they want efficiency then complain when the condenser is "too big", then they don't want to ever clean them or pay for them to be cleaned!
As a retired machinist my heart thumped pretty hard until you explained about the one two three blocks, :]
Got to have at least 1 rough set if your doing machine repair.
i thought exactly the same thing, "those better not be his good blocks!"
Ive never owned an extra set of blocks: my butt clinched automatically 😂
I’ve said it before and I’ll say it again. Video and especially editing are superb. The professional presentation in this video made a 42 minute video seem like 15 minutes. And I have no need to skip through any segments because you do that for me.
To take it all apart and put back together the right way is amazing in itself lol Awesome as always
and there wasn't any left over parts, winning! 😂
@@CuttingEdgeEngineering and you didn't have to make any replacement parts.
@@CuttingEdgeEngineering Do you have to consult the video when putting certain pieces back together? Or do you have a 'system' to how you lay out the parts? Or do you just have an excellent memory?
Curious enough to take it apart. Smart enough to get it back together. Clever enough to hide the extra pieces!
@@d.jensen5153 I'm wondering the same thing... I'm good at tearing things apart but yeah, I always end up with an extra screw (or three) loose! Or maybe they were to start with and THAT's the problem?! 🤣
I admire that you can just tear into your mill, fix it, put it back together (without a tin of leftover mystery parts) and get back to work. Good stuff.
Filming the disassembly helps 😃
I was thinking the same thing, start first thing in the morning and have it all torn apart, lunchtime run and get the bearing you need and food, second half of the day is putting it back together and boom ready for the next day. Wish I was that we'll organized an had the time i would need to be able to pull off something like that.
I like when he's fixing some worn out part of a machine and then just says, nah, I'll just make a new one.
I really appreciate the moments it appears you had a memory dump and your face goes blank and you stare at Karen. The laugh you both share immediately after is so heart warming to see you guys laughing and joking to try to recover. You two and Homeless are so endearing that is why we love you so much. You are a skilled machinist and have so much passion it is contagious! Thank you for a friendly fun and informative start to my day early morning in Alabama USA. Take care and keep up the good work we love to share your day!
Hey mate thanks for watching, glad you can enjoy the video and those moments, the videos take a lot of work and good to know they are being enjoyed 😁👍
Surprisingly, it looks like no one has yet asked to see or hear more about the drift car! Therefore, I will do so. Another wonderful Friday video. We watched it while enjoying our cocktails, as usual. Tearing into a milling machine takes a lot of knowledge and courage. Glad it worked out. Worn out bearings can lead to nasty problems. Thanks, Kurtis, Karen und Homey, from Bruce, Karin, Halgrim and Bella in Germany.
The instant you started tapping on the 1-2-3 block, I said to myself: "comments incoming"... :) Loved the immediate clarification.
What a great reminder of a job I did myself about fifteen years ago. "The same bearing sound" isn't a bad thing, and it's always good to begin again with new bearings and an actual installation date recorded. We easily forget the time and frustration of doing so with the years of no trouble that come after.
I think it still definitely sounds better, a lot of the bearings sounded very tired. Also, as others have said, I absolutely love the banter in the bloopers you two have. Great work both of you and thank you for sharing!
endorsed - "a lot of the bearings sounded very tired"
The outtakes are almost my favorite part of all the videos. It’s funny how some people want to call you out for using your tools a certain way. They are your tools and you can do whatever you see fit, with your tools. Thanks for sharing your knowledge and time.
G’day Kurtis,Karen & Homeless,
thanks a lot for another year of the best machining, welding, problem solving, filming/editing and ripping the crap out of rubber toys anywhere on TH-cam.
Have a great Christmas and please come back next year. Many thanks to the CEE Team. 🇦🇺🇦🇺
Hey mate thanks for taking time to watch & support the videos we appreciate it! Merry Christmas to you 👍
Liked before I even watched it! I spent a large part of my career as a Mechanical Engineer (now retired) dealing with bearings and I can say without fear of contradiction that the sound of a failing (or failed) bearing to me is right up there with the sound of fingernails on a chalkboard! 😱
It's always greatly reassuring when you get to the end of a job like this and there are no bits and pieces left over. 🙂
Nice to see the "bearing installer tool" of a socket n mallet is of common use as when I started had the old guys look at me like I was crazy.... if it works, well then it works!
I legit laughed for a bit when I saw that. Here is this channel where some dude is engaging in some very precision stuff on large heavy objects. He's whipped out tools and tricks I've never seen before more times then I can count. I couldn't even imagine how much money he has invested in tools and equipment. So when I saw him using a socket as a bearing installation tool like I do at home..... well I just found it awesomely relatable and funny.
@@ToolofSociety yes a lot of engineers do the same including me.
We need to see more on that drift car!
I sold her a few years back to help buy our first home but have always wanted to get another one, maybe CEE can sponsor it 😂
@@CuttingEdgeEngineering What kind of car is it? I've never seen one quite like it here in the states.
@@MrUltraworld If I'm not mistaken it's a Nissan S15 200SX (Silvia) so SR20DET which is Nissan speak for 4cyl, 2.0L, two cams and a single turbo hanging off the side.
@@Sim.Crawford Thank You it was sold in the US as a 200SX. I've seen a few with LS motors in them. A good-looking car.
@@Sim.Crawford spot on mate 😎👌
Kurtis has bigger and more balls than a herd of bulls to take something like that apart with so many parts and no instructions. Then to put it back together like he had done it a hundred times. More than just hats off to him.
Kurtis - your skills never cease to amaze me. And Karen, your videography is first rate! Well done to both of you (from central Oregon, U.S.).
good to see a machine being stripped fixed and put back together .... most people would have no idea how to do this ... good vid mate
cheers mate thanks for watching
and well lubricated...was cringing on the first bearings he put in, then he fired a few shots of oil and I was like "YES!!!" Plus all that white lithium grease he put in on the gears and sliding parts, left a smile on my face...cleaned, and restored and well protected for many years of awesome service!
I have never seen the inside of a milling machine before. Fascinating.
10 out of 10 for the job
My dad was a WW2 aircraft mechanic and one thing he impressed on us when working on the farm equipment was to always use something else between the hammer and the bearing. For bearings up to 2 1/2 bananas (63.5 mm) we would use a socket that fit over the bearing race. For really large bearings we would use a block of wood in place of the socket.
And that little "pop" when pulling using a gear puller is always so satisfying.
I gotta say, you’re one of so few channels that actually have and use a solvent tank!! Great stuff as always 👍🏻
Hafco have evidently put some very nice effort into building a quality milling machine as evidenced by the overall build quality you uncovered as well as nice details like balancing gears that they could arguably have gotten by with if they'd left imbalances few would notice. But you also added significant value to your own machine by installing better suited-to- purpose sealed ball bearing assemblies, by using polymer composite grease in the main gear case and by scribing the precision visual guideline as a visual rotational axis cross-check. Hafco cut (or spec'd) that top drive gear set "off the involute" to give it more robustness at the expense of gear noise. This also let them specify harder (but more brittle) gears there for better long-term wear characteristics also at the expense of noise. But the machine sure sounds sweeter than it did, and I'm confident you postponed any major maintenance on that machine by hundreds, if not a few thousand, operating hours. As an old manufacturing consultant, you're a joy to watch on the shop floor. Your success as a machinist is as well-earned as your, Homeless' and Karen's work in TH-cam production.
BRILLIANT as usual!!! Karen's editing is first class, I can't count how many times my friends would repair something, sometimes expensive machines, and not bother to clean it going back... as always, you set the standard for a "Job Well Done!!!"
I was impressed that you only used hand tools for the whole rebuild. Well done. A fine machine deserves that type of care.
taking apart stuff... I prefer to use hand tools too; much more precise and control if something goes wrong.
I do appreciate you giving sub-titles for the dimensions. I am a yank and are still trying to learn, and convert to the metric system. As a cabinet maker, all of my hardware is metric. When you have used the American system of measure for more than 50 years, metric is a challenge. Love your videos! Keep up the great work.
Honestly, it sounded a =lot= better after going back together - before, I couldn't even hear the gear noise for all the other dry-bearing racket.
The practical skills you display are second to none! My absolute favourite youtube channel.Many of my non engineering friends now hooked on the team of three from down under. Half a million subscribers in 2023 no doubt about that!
Wow thanks for the support mate, hope you keep enjoying it 😎👍
Very impressive rebuild……Kudos Mate……should get many many many more years of use out of it…….👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Yes, this is something I'd be scared to do. Taking complex equipment apart like this would make me highly nervous about being able to get it back together again. Curtis is braver than I am! A *LOT* braver.
He has a Secret Weapon...
Karen is filming everything he does so if he can't remember where a part goes, all he has to do is watch the video of him taking it apart...
@@HappilyHomicidalHooligan 🤣 good one
The taking apart is easy. its remembering where it all goes back together.
@@gl309495 Amen!
Have confidence in yourself, switch the negative thoughts off. It is a series of small jobs that make a complete job, take your time, one step at a time. Having experience obviously helps. But in my experience it always works out no matter how deep a hole you are in.
The Hunt for a Hundred Bearings. The sheer amount of bearing pullers displayed here was a show of force :-)
What a LEGEND !!! Finds smallest fail in the system bearings - changes everything to new. Getting new machine effect right after and long after the maintenance is done
It's a VS drive head, no matter the brand or where it's made they all have rattles, just turn the radio up a notch and fugitaboutit. Loved the PSA on 123 blocks, people would stroke out if they knew that 123 blocks are on the list of "consumables" in my shop😜
Gooooood Evening Queensland.......

Hey Paul, good to see your comment here!
@@CuttingEdgeEngineering always, now back to the action with the Milll, Cheers Paul
I’m thankful for the outtakes, finally see he isn’t perfect, well, still haven’t seen a less than perfect weld.. but I will
One of the best videos I've seen so far! It's probably also because I'm a mechanical engineer myself. And then again these cool outtakes that always have tears in my eyes. I wish you both a Merry Christmas and a Happy 2023! Stay healthy! Greetings from the wet and cold (-7 degrees) Bocholt (Germany)
Woot! Something like living by a railroad crossing, after awhile you dont even know the sound is there unless you think about it.
exactly!
As my dad used to say whenever the car developed another strange sound... Turn the radio up another notch son.. Worked every time ;) Thx for fun video :)
Before you pulled it apart I had it pegged as gear noise (just because of the rattle)but a new set of bearings won't hurt. Once again interesting, This is the type of work I did for 50 years,
Cheers Billo
Usually I'm always left with a bolt or two after putting things back together.
It's great that you have video for reference if you don't remember how to put something back.
15:59 I said “YAY” in my head when that came right out. Having pulled bearings with hack a tool in the past I appreciate your assortment and now that I have a lil bit of money I have bought my needed tools too….Gotta love the right tool for the job.
Nice job, well done. Loved your take on the 1 2 3 blocks, probably saved about 50 negative comments! They are handy though, use em all the time in the woodshop
Karen made me say something, she knew I would get grilled otherwise 😂
@@CuttingEdgeEngineering She was right! I was about to make a rebuke just as you stopped me!!
@@CuttingEdgeEngineering She's a wise woman! You putting that part in made me laugh because, as @mikeweagle5523 demonstrated, well, I'll just say, it was wise and not get myself into trouble with commentary! 🤣
@@CuttingEdgeEngineering 1 2 3 banana blocks :)
I was about to do the same when I seen it, in my head my best Aussie accent, " what ya doin mate". Then you corrected me.😵
I’d like to say how much I appreciate the quality of editing that goes into your videos. You do great machine work and it is showcased well by skipping over the more tedious parts and emphasizing the points of action.
thank you!
@@CuttingEdgeEngineering You are welcome and you deserve the compliments.
As soon as I saw the gears I knew you were never going to be able to make it quiet for very long. My old Van Norman mill has a 3 speed box with straight cut gears and there isn’t an oil on the planet with a heavy enough weight to keep it from howling. Great video! I have Mill envy!
I was always that kid who wanted to see how everything worked. So it’s very satisfying to watch you take things apart and back together.
Nothing better than a new CEE video with a hot cuppa after removing 4" of heartattack snow off the driveway.... Merry Christmas from Canada, thanks for all the great videos this year!
Merry Christmas! 🎄
I like the way you treat your machines. You treat them like buddies. When you need them they sure will treat you back like buddies. For a one man workshop I can see your passions in the trade. Thanks for your encouragement!
Damn, that was impressive, wow!
Absolutely love how you two interact, the endings are always so funny! 42:11
Awesome work as usual bud, I spotted that mugen handle on the quill yonks ago and always wondered if you had a history with cars. You handled this job the same way I would have done and it was a pleasure to watch, can’t help but think if this was done on one of the American machining channels it would be drawn out into a 12 part series and take 18 months to complete 😅
Yeah, with all the footage shot in one day!
I don’t watch that American channel anymore because of that. Kurtis just gets right in about the jobs, no fucking about. Problems are solved, not glorified. Job done. Next. Cheers mate, all the best.
Thanks very much, great video. I'll watch this again if the time comes when I want to pull mine apart.
That machine is really served you well first time you've ever done any maintenance on it in 5 years money will spent. I am really surprised they didn't steal that machine up better than that. Stay safe and enjoy the weekend see you on the next one.
Great video, lots of information.
That "control box" on the side of the motor is called a pot head or pecker head in my neck of the woods. I have no idea of why but I heard it at my first mining job as an electrician back in 1969 or 1970. I used to repair variable speed gearboxes that used the same Reed style sheaves and belts. My wood lathe uses the same setup today. They work great so why not continue to use them. The ones I worked on had two grub screws per threaded hole to make sure they didn't come loose.
Have a great weekend,
jack
I'm sick AF and miserable on the couch, interested in nothing; yet, I can focus 100% on this. You're awesome. Thanks!
Feel better soon!
Well...those two dry bearings and the two that seemed to have bad spots, definitely was a good idea to replace em...they more than likely wouldn't have made it too terribly much longer...prevented a catastrophic failure with a seized bearing!
Good stuff...love how Karen jumped when you yelled BANG when you flipped the power switch...LOL!
Keep em coming!!!!
I caught myself trying to tell you through the screen, that noise is mainly from gears not bearings.
But as you pointed out, it never hurts to replace bearings and clean up every now and then.
Consummate professional ! (Until the outtakes.. our fav. part) =) I hope Homie and his people have a fantastic Holiday Season!
Preventative maintenance can seem like a bit of waste of time but if definitely isn't. If it was done more often maybe your shop would be a little less busy!😉 Happy Friday - Thankyou K, K & H 👍
Absolutely fascinating to watch someone who knows what they're doing take apart something they're not familiar with and then put it all back together again with no leftover parts. Well done. I know through the magic of editing this didn't take very long but if I might ask, how long did this process take?
Glad you enjoyed it mate, we videoed it over 2 days with interruptions, otherwise would probably only be about 4hr job
@@CuttingEdgeEngineering Did having the video come in handy for figuring out where some parts went? I often take video (and always pictures) when disassembling something unfamiliar to make it possible to find where things go if I lose track.
Yep. As I sat here watching, knowing that if I tried this, the odds of getting it back together in working order if it was me, would be precisely zero. I'm remembering the time I took apart a much simpler tool, then put it together, only to find parts laying on the bench underneath I had forgotten. Taking it apart and then back together the second time did go faster. :)
Err somone who knows what they're doing?
Would have not done all that work and keep the fault intact.
@@agentx7138 He did find multiple bad bearings and was able to clean and degrease/re-grease everything. Preventative maintenance. Now instead of it failing when he has jobs to do it will keep working.
I used to be a maintenance fitter at International Harvester back in the 70's and did the same type of work. Really enjoyed the video brought back memories.
I don't know, maybe it's just me, but it is soooo satisfying to replace crusty bearings with new ones and feel the "smoothness".
I love a good tear-down and rebuild. Reminds me of the 80's when I worked in the maintenance section of the factory.
79yr old mechanic. I admire your work. My son just rebuilt his Bridge Port. Me, would have leftover parts.
I love the machine explanations and fixing videos along with all the other ones. Thnx for taking the time to share the fix . Cheers from Vancouver Island BC Canada.
Thanks for watching!
As always... loved the video. you're a brave man pulling that all apart yourself but I imagine that saved a boatload of money doing it yourself. The "BANG" @42:03 and accompanying camera jump was effing hilarious! Thanks for the laugh!
Yep, that bang was comedy gold, I get my Mrs with that all the time 🤣🤣🤣
So awesome to have this on video. Not only for reassembly for yourself if you needed it, but will probably end up being an invaluable resource for someone else somewhere in the world. Keep making chips!!
Curtis, as much as I love your various videos of you repairing other people's equipment, I have to say there's something surprisingly satisfying about watching you do a shop infrastructure video... especially seeing and hearing the finished product... absolutely beautiful. Best wishes to you, Karen, and Homie in the holiday season and in the new year!
Thank you for making the video. One of my favorites. It's not customary, but necessary.
Glad you liked it!
You have done well replacing the Nachi bearings with FAG.
The company I worked for had large bench drills. They had large gearboxes flooded with oil, they made identical sounds. I thought it was normal from the beginning too, until someone pointed it out in the comments. The milling machines had helical gears and only the motor could be heard. Greetings from Poland and sorry for the language is Google Translator. :)
@ Sawa Tresor, there's nothing wrong with your English mate, Giggle translator did a good job!
Some lads that worked for a few bearing companies told me to chill bearings with dry ice and alcohol if you can't get a hold of liquid nitrogen.
Worked a treat on some Subaru wheel bearings.
Cheers
Love your work
Those 3 prong bearing pullers I always found it troublesome to keep the prongs separated wile I tighten down the screw. I found if I put a piece of shop rag between the prongs it gives it enough resistance/springiness to keep them apart till the screw is tight. Especially when it’s horizontal and not vertical. Then it’s easy enough to pull the rag out once it’s tight. A tip I found works really well. Maybe someone else out there can use it.
good tip thanks for sharing mate
Maintenance, the unsung hero of every company. How on earth did you keep track of all of those parts? You could do a whole video on that. Again, Karen's video skills were excellent. As for me, I was impressed that not once did I hear you say, "Karen, hand me that wrench.".
Take clear photos of each assembly before taking it apart. Photos have been invaluable to me during reassembly many times.
"How on earth did you keep track of all of those parts?" This is what I wanted to know too.
Always recall the forklift driver who left the company and got a new job. However one of his key jobs was greasing the machines in the morning. 2 months after he left there was 100k of scrap produced when the fixtures became worn…..
@@ellieprice363 That's how they do it in old car restorations. Tag, bag and photograph. With phones these days it's a lot easier than it used to be. For car restorations, the rebuild can take years. Nobody remembers what goes where.
I just love those satisfying clicks the bolts make when they come undone. The filming quality and timing just gets better and better over time and it's so amazing to see!
Been catching these vids on time. Just broke a main powerswitch on a massive graffenstaden mill, a machine I think you would like.
When you got deep into the disassembly it started getting quite complex and involved. I'm glad you managed to get it all sorted out with no issues. The design of the mechanical speed control was interesting.
One might think that split pully enabling the variable speed is a new innovation but it's rather old. I have a 1964 john deere garden tractor I rebuilt and it has that design to give a range of speed for each gear

I'm rather impressed with the overall engineered design of this machine, especially the bearing carrier. Makes it a LOT easier to service. There are too many other modern machines not well designed for servicing. Neat vid, thanks for posting!
It is NICE to see relatively new equipment well made from the outset that's maintainable too. In the past, made to last and be maintainable was the norm. There is far too much planned obsolescence currently.
Another awesome video James! What would be really cool in my opinion is if you had a little timer on the bottom right or left that gives the actual amount of time you've spent to get to whatever point you're showing in the video. That would allow people to see a realistic guage of time spent on each project. Keep up the great work!
That would be nice also for Isaac & Gregg all 3 get into things that take awhile to get done
One of the most satisfying tasks of a mechanic - the cleaning station!
Great videos!! You are very methodical and thorough. You were right in replacing those bearings. From my experience the 2nd source of noise is the backlash in the gears. You may want to check them and see how much out of spec they are. I replaced the bearings in a Bridgeport and had the same thing happening quieter but still loud. I then check the clearances on the gears themselves and they were way out of spec. I had a frien that had a brand new head that was damaged in shipping years ago and offered them to me. We got them off I replaced them with the newer ones given to me. It was a very quiet mill! Success was sweet.
As a tip, in the future if you need to rebuild the head of them. Just take the four bolts loose that hold the head to the ram assembly. We had a few machines go out for rebuilds at the shop I used to work at, and that is the beauty of bridgeport style heads. Four bolts, and you can take them off. If you want them mounted vertically, just set up an angle plate on a bench and you can keep it vertical. While obviously this is hindsight for you, it is something to remember in the future in case you need to pull the head off again.
🤔 he did take those bolts out. How is that a tip?
@@pawz007the tip is he didn’t need to remove the ram just remove the 4 bolts holding the head to the ram , the 4 bolts in the front, and leave the ram on the base.
NO MANUAL:( … I’m BLOWN away! YOU are definitely “PRO” level. I love all your videos. Karen is awesome with the camera,editing. Keep em c’min 😊
Good Morning CEE; Great video this week. Kurtis you are amazing. I would have never tried to tear down a critical piece of equipment that complex. Well worth the effort given the number of bearings you found going wrong. Thanks from Halifax, Canada Have a great Christmas.
Maybe there's some Halifax hashish in the hamburgers? It's really not much complex. Like Kurtis says, follow ya nose and keep at it, sorta thing. You can do it to Mr. Weagle. Keeping the parts where you want them is always helpful. Like taking video of the procedure while tearing it down and paying attention to how it's constructed .
I'm glad to see you again, I really like the way you work👍
Thank you! Cheers!
I love seeing someone who really knows what he's doing, working with big machines and creating stuff of exceptional quality. Makes my shop look like crap, but there you go!
Super nice video, with great closeup shots, and provided knowledgeable information throughout the teardown and reassembly, my sincere thanks to both you and your wife for an extremely well-produced video.
