A tip when assembling the motor use a piece of studding in the back plate through the outer cover which will make alignment easy. 60 years ago I used to repair motors the major failure was over heating from blocked fans or losing a phase on 3 phase motors. You found out the hard way not to pull bearings on the outer, we all make mistakes at least you fixed it.
Kyle, I was yelling at the screen "you forgot the back plate"..Lol I've done that a few times...it happens. Also good to see you opted for rubber sealed bearings.. My opinion it's the best way to go. Man those drive belts are so over engineered, 3 is probably adequate for that Hp. Carful not run the tension too tight with that many belts it's easy to overload the bearings. Looking good and coming along nicely 👍👍 ATB....
Yeah I was hesitant on shielded vs sealed. Just due to heat rating and drag but my bearing recommended sealed and I am glad I did. Yeah agreed w the belts. I usually tension them by gravity run it for a bit let the belts loose their memory from sitting on the shelf then re tighten later.
by the end of the project the lathe gonna be brand new!! it's gonna be very satisfying to see the finish result after the complete video series, amazing work.
Kudos for adding any errors to the film , many people will be learning a lot from these and mistakes are part of the process.Great standard of work as ever , looked as if the “tweak” may have occurred from pressing the race seals rather that the inner race ? Enjoying seeing the older (quality ) machinery being nurtured and prepared for their new working lives, all worthy.thank you & keep em coming!
Nice one. Always amazed by the weight of the older industrial motors - bought one on EBay for my band saw not too long ago; when I saw the crate on the forklift, changed my mind and bought a Toshiba
Kyle, next time heat the bearings in a standard kitchen style oven, throw the rotor in a freezer, then do similar with the bells. That way you will have a much easier time assembling the motors. SKF, has a great deal of literature, on bearing care and installation. The explorer bearings are superior, and will give an exceedingly long life, when treated properly. We had lots of fun with 30-800 hp motors. Retired now.😎 Best wishes from the far North.
I have never understood why people go to all the trouble of opening a motor up to then decide the bearings don't need replacing. I'd always renew them, unless I knew that they had recently been replaced.
A tip for next time, when reassembling the motor (big one) those covers that go before bearings and bolt to main motor covers are easier to assemble if you put one threaded rod trough one hole than put a main(bigger) cover trough the hole where bolt goes, that way you don't have to keep holes aligned. 35 years of servicing and rewinding motors... Edit: 26:34 if a bearing goes on the shaft you press it on inner race of a bearing (never on the middle, where balls are), if a bearing goes in the cover of a motor in this case, always press it on outer race of a bearing
I enjoy watching your work. Your are very talented for someone your age and appear to have a lot of experience. As a machinist though, I find it odd that you would put the center of your puller in the centers on the motor shaft. I my day the machinist would chew my but as this damages the centers and creates more work for them should they need to due machine work on the rotor. All in all though I am really impressed with your abilities.
Yeah the only one taking this back apart is me and in that case it’s probably getting replaced. As a general rule you are correct but in my shop I can make those judgment calls
I might add, and pardon if I missed you explain this, that NEMA (National Electrical Manufacturers Association) was founded in the early 1900s and began codifying electric motors into a set of standards that define motors by frame type, mounting style, bolt patterns, shaft dimensions, and other physical characteristics as motors had or were becoming ubiquitous in not only industry but in everyday life for the masses. It’s easy now to look up and find replacements for motors without having to rely on the OE. Instead, you can substitute a “generic” motor based on its Nema code!
I don't know if you have a set of wedges but they can be handier than chisels for separating as the point is very thin. McMaster has many sizes, forged steel.
Great video. But if you set the bearing in the endshield then press the rotor shaft in too the bearing all force are pressed to the ball Cage. Thats a big NO NO. That can cause a much shorter life spaan of the bearing. But Great video. And very good job of you repairing the lathe.
Nice job refurbishing those motors. You certainly added years to their lives. One note, it would have been been interesting to note which brand bearings you purchased. So many bearings are made in China and are absolute junk compared to the higher end bearings. Lots of people don't understand that cheap cost bearings mean cheap quality bearings. It sucks having to do things twice due to it. Many local auto parts stores sell the cheapest quality bearings for automobiles that fail rapidly. I'm enjoying the refurbishment of the lathe to date!
@@VanoverMachineAndRepair I meant to say it might have been good to take a minute and discuss the importance for people to not cheap out by buying crappy bearings for newbies who don't know the difference. Hopefully you didn't and I missed that. 😉
I'll bet the factory guy who put those cover panels on originally never would have dreamed everyone and their dog would have battery powered right angle short reach hex ratchets. :)
I’ve watched some of her videos too! Cute girl that usually dresses in nice overalls and she goes around to different villages and redoes motors for the townspeople???
You really know how to ``drive`` the interest up... This some very motivating shit, mane... Puns aside, was that round stock properly cleaned before being used to drive the bearings in? Did you wash your hands? Because it doesn`t look like it... By the power vested in me by Robin Renzetti, i condemn your heretical efforts and excommunicate you from the church of smooth rollers! Ave Deus Mechanicus! Thou art to seek redemption in the limbo of lost sockets and overtorqued bolts! But no really, those hands were not clinically sterile, nor was the press, i could see it, and while these may be sealed/shielded bearings, that does not excuse the lack of proper protocol and mechanical rites of sacred insertion... ``When thou handles a precision orifice, and when thy will is verily to insert a hard circular member into said orifice - thou art to handle yourself and thy member and the orifice with sacred dignity; thy hands are to be clean, thy member is to be immaculate, the orifice as pure as the heart of the stars; thou will rely on proper rites of foreplay as to induce thermal dimensional delta adequate for contactless insertion and thou will not rely on bestial acts of brute force; the form of the member and the orifice are irrelevant - whether thou art to thrust a hard shaft into a bearing, or a bearing into that one`s seat - thou art to observe the sacred rites!`` Your mechanical trespasses and transgressions aside, i gotta thank you for the motivation to see to a few of my motors... Been considering it for a while now, but what does a man with a lot of machines not consider... The instant you get a few machines, there is always something on your mind - be it a project, a repair, a modification, a custom part, a custom part for something else(like your car, or fridge for that matter, or a shower(damned plastic pieces of shit that break))... Anyways, imma go huff some rank headstock gearbox fumes from a small tapping drill... Tho, the diesel and atf mix should have at least consumed some of the stinky crap... Guess i`ll find out in a few minutes... Best regards! Steuss
I’m glad you finally have your chuck keys not in the chuck. You do such awesome work to make such a rookie mistake
Swing out motor door. Kudos to the engineers that thought that one up. Way better than having to wrestle it out of a tight space.
Agreed.
Yes, I was impressed with that design feature!
How do you mount it on again with the hook on the top side of the motor?

Thanks for the tip on the bearing splitter and puller combo. Great utilization of existing tools!
You bet!

lol true that
Wonderfull. On paint, it is best to paint the motors in matt black, this will disapitate the heat more faster and further help in cooling. 🐞
Good to know

Muy bien amigo que buena reparación 👍
Thank you
I don't know if you have a set of wedges but they can be handier than chisels for separating as the point is very thin. McMaster has many sizes, forged steel.
Yeah I do good idea
Rotor spins (rotor: rotates) stator, stationary.
Thanks

What is the correct method to install the bearing then?
28:20 lovely rendition of jingle bells
Very true that was not intentional

You gotta paint a huge lion with snarling teeth on the lathe.
Good point
Forty years ago my friend and i repaired a thirty horse motor that had sucked in so much dirt that it locked the rotor !
Wow crazy
wonderful.....thank you so much.....pb
Thanks Paul

He did show that they are SKF. i.e. high quality bearings
Yeah skf but agreed I shy away from Chinese bearings
@@VanoverMachineAndRepair I meant to say it might have been good to take a minute and discuss the importance for people to not cheap out by buying crappy bearings for newbies who don't know the difference. Hopefully you didn't and I missed that. 😉
He showed the box they came in.
What cleaner do you use on the rotor and stator?
Light apc I think
I'll bet the factory guy who put those cover panels on originally never would have dreamed everyone and their dog would have battery powered right angle short reach hex ratchets. :)
Yeah very true. Rewatching the edit I am surprised I braced the fall with my boot. That cover is heavy easily over 100lbs
19:40 Stator is stationary, the Rotor rotates :)
Thanks
no jewellery in the workshop!
👍
Just out of curiosity, what are those cage looking things on your shoes?
Check out my other videos I did one on then
Small motors are not always cheap
Yeah I am seeing that now looking at some 1hps they are surprisingly pricey
There's this Chinese girl on TH-cam who refurbishes these motors, with only the basics of tools. Rewinds them as well, by hand.
kids in my basement do this well too.
I’ve watched some of her videos too! Cute girl that usually dresses in nice overalls and she goes around to different villages and redoes motors for the townspeople???
@@robertmason8341 That's her, yep :)
Yeah. It’s also a ruse I think.
I saw that 10 years ago except it was a man and he was on the sidewalk
Would it have been better to leave that beast mounted on the swing plate for ease of removal and install? Why does it exist?
Yeah if your not doing much but full disassembly is requires to clean under back side. Also I can work on the bench instead of the floor.
