- The Full Monty !
The new bearings are fitted & the spindle is installed & adjusted .
The lathe will then have to run for at least 6 months for a final adjustment .

Probably the most comprehensive headstock bearing adjustment video I have seen !
Only thing I can add to it is for lathes that run greased bearings ( mini lathes that have had a taper bearing conversion etc ) is to adjust out most of the end float and run the lathe on low for a good 15 min - this lets the grease disperse ( you don’t need a lot of grease either as too much creates drag and heat ) then check end float and re adjust - once you are close to zero run the lathe about mid range to heat soak the spindle and do the last adjustment . Greased bearings will run hotter than oiled bearings especially when you start spinning taper rollers at 2 grand . Finally don’t do what I’d did on my mini lathe and fit lip seals in the bearing shields - the extra heat they generate is astonishing !
Ripper video Max ! Thanks mate !
You are spot on with the heat generated by lip seals , it's surprising .
Hi Max, another fabulous video. Im hooked on this channel. I wish I knew half the stuff you know. Cheers Mate,
Thanks 👍
Learned a lot from your lathe rebuilt. Loved the method you used to preload the main bearing. Keep your standards high!
Thanks .
Interesting series of videos. Thanks!
Thanks 👍
Excellent mini-series - Really appreciate all of your efforts to get these videos produced. I learned quite a bit. Thank you
No worries , Thanks 👍
Well Done Max! your bearing setup is spot on. Good to have the old girl back in action. Enjoyed !!
Thanks Dean .
Many thanks for this info. Kind regards Tony
No worries 👍
really enjoyed this one Max, lots of detail, and I reckon I would feel confident enough to have a go at doing my own after watching this!
Thanks .
Pure F*****n brilliance, thanks for sharing your amazing work Max, could watch your videos all day, look forward to next one, cheers and all the best mate.
Thanks .
Gday Max, thank you for showing your way to preload the bearings, on video the sound of the lathe running is much quieter then before, I went back to a previous video to see, great series mate, throughly enjoyed watching, have a great weekend, cheers
Thanks , good for another 12 years !
The next best thing to having a new machine. After that you deserve a cold one, Cheers Max!
or 3 , it was hot !
Really nice camera angles on the Lady ," I mean Lathe ," LOL . Very interesting repair and another fine job Max !
Cheers !
G’Day Max, just binge-watched this series. I admire the calm confident competence.
Thanks .
Thanks for another great learning series. The bearing tips and demonstration were priceless.
Thanks Rob .
You can have four beers after this job !! I am having one just watching !!
Cheers !
Good job max it worked out well
Thanks .
Max thank you for sharing about preloading bearings. It was great to learn a lot in this lathe rebuild.
No worries .
Just did mine last summer. 900$ Canadian just for the spindle bearings. Good job and great video 👍
Thanks .
Great tutorial Max. I have a 1988 AL960B here in Mandurah WA and have watched all your overhaul videos. Great info and tips for my old unit.
Thanks 👍
Really interesting Max. Great watching your skills changing and resetting the bearings. The main bearings are unbelievably cheap to say what precise work they do. Tony
Thanks Tony .
I love seeing this kind of shop school. It really amazes me how accurate these machines are.
I'll be here when you make the final adjustment in 6 months or so, cheers, 👍👍
Thanks .
Another "Good work" job Max! Appreciate you and you sharing it with us. Learn something every time I watch one of your videos. Thanks, and Have a goodern!
Thanks .
Thank You for this video, learned some stuff.
No worries . 👍
There are times it would be handy to be an Octopus!
Sounds sweet Max.
Good work.
Would be good to have 3 arms sometimes !
Thanks Max for the whole series. I have much higher confidence I could do this now. Cheers Mate. 👍👍😎👍👍
No worries !
My best regards to the engineer who had the idea of putting those holes there and to you for demonstrating their use.
Thanks .
Cheers for this man, really helped me out
No worries . 👍
Hi Max Just back from Falcon. No cooler there. As always very straightforward and helpful information. Your considered approach without some of the YT heroics is very refreshing. Peter
Thanks . Hopefully we are near the end of the over 40 deg temps !
This been most helpful , thanks😅
No worries 👍
Nice work Max I’ve really enjoyed this series. That was a bit of a tricky bastards to get the gears back on the spindle. Great information too on setting up the headstock bearings.
Thanks .
Good tutorial on setting bearing pre-load, Max . Much better than the hit or miss technique I used when I replaced my spindle bearings -- will remember that the next time I set the pre-load . Thanks for the info !
Thanks .
I never would have guessed that the bearings would slip like that.
Stranger things have happened ! 👍
thanks for that Max, that was one of the most informative videos i've watched in a long time. Hats off to you !
No worries !
Max, very well done, excellent reasoning and beautifully explained.
Thanks .
Hello Max! new subscriber from Sweden my name is Jesper.
I'm 23 and appreciate every bit of advice.
Keep up the good work!
Thanks . 👍
Really enjoyed this bearing swap series, learnt heaps, Thanks Max.
On silastic your mate Alan Moffat love the stuff, he did all the TV ads
Lol , He used it to stop the windows rattling in his Ford when a Holden blasted past !!!
Thanks for all the information on bearings and the end play, we're building a lathe from scratch in our shop, was really needing that information, again thanks sir, can't wait to see next video!
No worries . Building one or reconditioning an existing one ?
@@swanvalleymachineshop building one piece by piece of steel
Wow. What outstanding results. Sounds a ton better as well. Great repair Max!
I agree. Great info to reference later.
Thanks .
Thanks Tom .
This was very helpfull, i´m thinking of making a basic lathe for my shop, and finding out i have still a lot to learn on these machines. Thank you very much!
No worries 👍
Great video Max and very, very educational. Thanks.
Cheers . 👍
Max, the background noise sounds like your shop is next to a pub. What a great place for a shop.
Bloody noisy neighbours ! Cheers .
This is fantastic. Brilliant solution for pushing that old bearing off. I have a very similar lathe from the early 90s that needs a bearing change, will be using your method. Also the best explanation of how to judge pre-load that i've seen in a vid. Thanks! Also Also, "Re-Nip" has been added to vocabulary. Cheers.
Thanks .
Great series of videos Max. Thank you for sharing your experience and skill with us.
I now have a little less trepidation about doing all of this on my Maximat Super 11once outside temps get to stay above 0 Celsius.
It's just been dragged 4,200km across Canada to the Atlantic provinces and awaits re-assembly in my insulated shed workshop.
Thanks . That's one cold place where you live ! Cheers .
Golden lathe refurbishment max very interesting to watch 💯👍🏻🇬🇧
Cheers 👍
Max, this was a wonderful lesson on adjusting headstock bearings! And, I suspect, _much_ more understandable than what's in the old Timken Engineering Handbook that I inherited when I started working as a Mechanical Engineer in the early '80s. No-one was interested in it when I retired (probably because it wasn't "digital"), so it followed me home.
Thanks . They have some great info the old books . Cheers .
Great video, Max! Was almost late getting to work this morning watching this 🤣. Always need clever ways of pulling stuff apart at my place of employment and anything to do with machine repair these days is infinitely helpful 😁.
I noticed how quiet she was running too when you spun her up, well done! If I had 4 thumbs they'd all be up lol. Cheers! 👍👍😁👍👍
Thanks Chris .
G’day Max I’ve been following you for a while now I’m glad that you showed how to do this it will come in handy. It’s true that I always learn something from machinists like yourself I have subscribed Max and look forward to watching the channel. Thanks mate kind regards John
Thanks 👍
Great job! you made it loo easy.. Great results you got with non-precision bearings
Thanks .
Great video. It reminds me why I hate doing this.
Lol ! Thanks .
Cheers Max, nice job mate, it runs like new.
Thanks .
G'day Max, absolutely fantastic mate, great to see the old girl running sweet again 😀
Thanks 👍
Thanks a lot , Max , that was a fantastic video ! Very informative
No worries !
fantastic vid
Thanks .
Wow! Thanks for this VERY interesting part and series. I needed to adjust mine...now I know. Thanks very uch.
No worries !
New Sub here and Thank You for the great content! Excellent thorough presentation of a Job that most of us will tackle at some point whether we choose to or not. Thank You again and look forward to seeing your future videos.
Thanks 👍
Great school keep up the great work Max
Thanks .
been looking forward to this. have a good un Max. keep up the great videos
Thanks .
Great results on the headstock play. 👍🏴
Thanks 👍
IR thermometers don't like shiny surfaces. Putting a piece of black tape, electrical tape works great, on any shiny surface will give you a better reading :)
Awesome video!
Thanks 👍
Thank you for sharing your incredible expertise
No worries !
Nice job Max, got to be happy with the run out and quiet running.
I replaced the cheesy gear selector indicators with 1.5 mm aluminium covers, machined to dia and parted off, used Stainless Steel round head drive rivets to show the position.
Yes , pretty cheap . No one would know there are adjuster screws under them !
Nice one, Max. I really enjoyed.
Cheers !
👍Great end to the series Max with lots of great info of what and what not to do.
Also, don't forget to put that spindle end cover back on or you'll be making a mess on the shop floor. LOL 🤣
Cover on , no mess !!!
I'm impressed with those plain axle bearings that was a good call using those and gears sound fine maybe they lapped themselves together enough they'll run forever, great how to tutorial dude am gonna grease all gaskets now greasier the easier haha
Yep , the greasier the easier ! Cheers .
Max, given your heatwave at the moment heating the bearing to 100°c will only be 10° higher than in the shop! I like the inventive use of what you have on hand.
Thanks .
She's sounding great Max. Back to working order. Thanks for sharing the tips. Yeah, its still frikkin cold up here. Send some of that heat our way mate :) Gilles
We have heaps to go around , 43 Deg C today !
Perfect timing, I’m about to do this to my Hare & Forbes “runout master” 🙄, thanks 👍🏻
Cheers !
That was a great little series Max 👍 Very in depth with the usual great tips. All thru it I have been thinking " Mine is fine and should not need this for at least 10 years" but after hearing the difference I am now a bit scared 🤣
Hey Bill , check it's not just the change gears on the back . Cheers .
Will do mate, Cheers 🍺
That's an incredible result for plain non precision bearings! Only a few micron runout is incredible. For reference I put p5 precision taper roller bearings and had about 4 micron run out on my Wabeco lathe. On my milling machine I put in p4 precision bearings and had 3 micron run out. It looks like you go very lucky with these bearings or timken makes really good bearings.
I think i may have just got lucky , or any run out from the spindle & bearing combined evened out !
Nice job!
Thanks Chui .
Nice job. Can't ask for better than that for run out.
Yes , i was impressed !
Ya have a lot of patience keep up the good work
Cheers 👍
Very good job MAX,,the old school forever
Yes , old school forever ! Cheers .
Looking Good Max....
Thanks 👍
Excellent job max, beer o'clock now Great video, keep'um coming...
Thanks 👍
very good video!!
Thanks 👍
Lots of great tips Max. I like how you did the preload on the headstock bearings. I need to remember that. Those bearing are much more expensive here in Canada. I use 6203, 6204 and 6205 often. 30211 is $86.14 and 30212 is $94.91. Thats about $95 and $103 Australian. I think I should start to look for a new supplier. Another well done rebuild. Thanks Max
Thanks . I would have thought your bearings would have been much cheaper there . I am lucky to have a major bearing supplier just down the road .
When I did my little Chinese lathe my spindle bearings were in the $80ish to.
Methinks you have a better relationship with your bearing supplier than we do, hahaaa!
Nicely done, thanks
Cheers .
BIG HELP ,,THANKS
Cheers !
Very useful thanks.
Cheers 👍.
Hi Max very good repair of the lathe, for 100 dollars it is all fixed up to make lots more chips!
Good for another 12 years !
Great job, nice detailed tutorial on taper roller bearings for axial thrust application, as you say, taper rollers don't like pre-load, the get hot pretty quickly at light or zero loads, heavy loads helps transmit the heat fully with roller contact. Obviously when actually turning, the rear bearing could be flapping about, the rotary friction welding machines I used to install had a spring cartridge on the rear to maintain alignment and gave support to the rear transmission belt drives. Rear bearings are smaller than the front, on bigger machines, the front bearings were double or triple stacked. Sizes ranged from 8" bore inner cone, to 18" diameters.
Again, great job,thanks for sharing.
Thanks . Rotary friction welding would be great to see in real life !
@@swanvalleymachineshop I've been working on RFW since 1989, still great to watch, even when I am doing weld development or for the first time on a new machine or new tooling, can be bum clenching time😵.
Can take hours to cut and section the weldments, prep them for a bend test and both macro/microscopy.
I've met many in a bar that say it doesn't work, or you can't bond copper to steel to aluminium etc.
Is the heat cooling down yet?
Best regards John.
@@bostedtap8399 Still hot . 43 Deg C yesterday !
@@swanvalleymachineshop Ouch!
Jeebuz, couldn't get over the price of the bearings, I've been pricing spindle bearings for my Hercus 260ATM, and I'm pushing over $500 for the good stuff, just hope I never need to change them.
Thank you for this series, Max, I've learned a crapload, it still scares the shit out of me though, really impressed you didn't swear while you were putting the spindle in, either that, or brilliant editing;).
Have a good one,
Scott.
No , did not loose my lolly at any time !
Excellent. Nuff said
Thanks 👍
@@swanvalleymachineshop Max i am in the process of rebuilding my Causing 5913 lathe now. I am following along your lathe project including cleaning the ways and saddle. Just what I need to see at this time. Thanks for all the time and hard work making these videos.
Thanks for sharing 👍
No worries !
Beautiful explanation and methods.
Timken bearing leaves much to be desired.
Thanks 👍
That spindle setup looks very similar to my cholchester clone and I need to do this job on it
Thanks . If it has back to back rollers at the front , it may have a different spec . Cheers Adam .
I thought some of your headstock looked a bit different to mine. I now know why: yours is a 2 x 3 gears, mine has 2 x 4 gears - all the components look quite similar, but a few things were clearly different, and I couldn't quite tell what it was. Nice work, as usual!
Thanks .
Hmm interesting pressing solution. I would have thought the bearing would have been a bit more pissy and stubborn breaking loose. Nicely played!
Thanks .
Hey Max great job your attention to detail is spot on and i learned some new tricks of the trade from watching you video (roller contact ) .I think those bearings will work just fine and i don't think you will go pass there speed rating . I watch some videos and went with the precision ones i have a precision matthews lathe din''t ask them but looked on grizzlys web sight they had one bearing and the price was like $800.00 crooks . The large spindle bearing was hard to find online in NSK made in japan i found one duplex set new old stock so two bearings for $150.00 and found the small one for like $85.00 each got two on EBay for $150.00 going to stick with NSK bearings for the rest standard grind . I don't like chinese bearings to me there rough and noisy . I know this is a long story not a comment I'll try to keep it shorter . Again Thanks a lot for the videos and can't wait for the new shop five thumbs up on your channel .JM
Cheers . I keep well away from those chinese things as well , where possible !
I have never had to do the headstock on a lathe, done a number of other gearboxes and shaft alignments over the years though. I think I'd have put a shaft (a couple of mm clearance) from the tailstock right through the spindle to a decent bracket spaced right back from the drive side. I would have taken the selectors out, no matter the roll pins and would then put all the gears, bushes, circlips etc on over the shaft in order and would then slide the spindle in, not far out of alignment with where its supposed to be. May be overthinking it again, but hey.
Overthinking !!! Good idea though ! 👍
Great video series. Not sure if you can edit the video titles, but if you can maybe consider adding the name and model of the lathe in the title so folk can search CZcams to find them in the future :)
Probably a good idea .
Thanks .
Heat up the bearings, they slip off then, the interference is very small, I just done the bearings in the headstock of my big Kirloskar lathe with new Gamet bearings £3000! and had to make a pair of headstock gears and a little heat was all it took. The spindle has a 4" bore with a D1-11 chuck mount. It's interesting that all modern lathes use the basic design first used by Colchester for the spindle bearings and labyrinth seals. Good video all the same.
Thanks . Not the sort of spindle you can pick up with one hand & put in the press ! Cheers .
@@swanvalleymachineshop i've just subscribed too!
@@crozwayne Thanks . This is how i do bearings with heat ! czcams.com/video/5MGGtAGVVpE/video.html
Hey Max going good so far you could always review one of your videos .I'm at 17 min. I'm going to finish watching. JM
Thanks .
Thanks for the information Max, will do a run in process with the new bearings ? Thanks again your content is always down to earth and very informative
I ran it for a couple of hours before that final adjustment on the video & will re check in about 6 months or so . . Cheers .
The Grizzy manual for similar lathe says tighten nut extra 1/16" clockwise measured at outer circumference of nut after zero end float and zero preload is established. Hope that helps.
Thanks . That would be similar to the last tap using the sharpie marker as a reference on my one . Did that manual say if it was a operating temp adjustment or a cold adjustment ?Cheers .
👍👍👍
Cheers .
we heat the bearing and sometimes wrap the shaft in plastic and put in dry ice or just ice
Thanks . At work we use liquid nitrogen .
@@swanvalleymachineshop I do service in 500 shops and most would not let me bring in liquid nitrogen, I even have to document WD40
@@garylarson6386 I guess it would have to be on their MSDS ( material saftey data sheets ) .
Maxie, thanks for the thorough demo of setting bearings on a spindle shaft. Enjoyed the checkout also. Guess with shipping and all cost about $150 As. which doesn't seem bad. How often would you do change out? By hours or say every 5 years. Love watching, thanks.
Only changed because of the noisy countershaft bearings , they lasted 12 years . The spindle bearings were still good except for the radial scratches from particulates in the oil . I could have re used the spindle bearings but they were cheap , so they were replaced .
Hi Max. I considered putting magnets in the top oil channels but decided against it as the bearing drip feed hole might get blocked and ruin the bearing.
I did , but was careful how they sat . Used real earth ones . 👍
