Hybrid table saw bearing replacement

My table saw was getting loud. One of the bearings had worn out. I managed to get the old ones off and the new ones out without having a press and without completely disassembling the saw.

[@josephseyfried1430]

I was putting this job off for years and my saw was getting quite loud. Seeing how you did it was a great help. My biggest barrier to starting was I envisioned having to take the whole saw apart, showing how to just remove arbor assembly was brilliant. Removing and pressing the bearings back on was not as difficult as I feared. Saws must use a light interference fit, I was expecting needing a heavy press to accomplish this. Your tutorial was excellent and I liked how you didn't hide the trial and errors. Showing/describing the little mistakes was so very helpful as it really highlighted potential pitfalls. All in all great job.

[@sebuteo]

Thanks for posting this Matthias. This video has been really helpful for me, as I need to replace the bearing on a circular saw, which I damaged whilst removing it. Seeing how you pressed the new bearing back into place - without recourse to the specialist tools one can buy (which I can't really afford) - was the key part. Thanks again.

[@captainquack9116]

I've never heard you as genuinely happy when the pin moved ever. It was nice to hear.

[@dadlaponizil3687]

Dear Mr. Wandel. Thank you for inspiring me and forging the repair road ahead. I am particularly grateful for this video since I am going about re-greasing or replacing the bearings in my trusty Craftsman 10" table saw. Ahhh, wish tools were built this well today. Gratefully, Dadla.

[@ronyerke9250]

Very nice. You did a pretty good job of improvising without the proper tools, too. 👍

[@McClimber234]

Amazing how bearings actually hold up to so much use. Cars, motorcycle, tools, etc

[@kiwdwks]

Good for you Matthias...glad you brought it back to life. Your innovative thinking always inspires me...

[@ManCrafting]

I love the jig you set up. Also the wooden bearing press. I recently had a similar repair on the arbor on my lathe. Having never had to do that repair before, it took me a little longer than it should have. Removing bearings a second time happened to me as well. Live and learn.

[@deadfreightwest5956]

Many years ago I did this to my Delta contractors' saw. I, too, used SKF bearings. At the same time, I ditched the v-belt and sheaves for a ribbed flat belt and sheaves (all parts from McMaster-Carr). What a world of difference! Quiet, and smooth as oiled glass.

[@andrew5792]

Matthias, not much help now but if you put the shaft in the freezer it should shrink enough to get the bearings on without too much effort.

[@rolliekelly6783]

As you cool the shaft, wrap the bearings in aluminum (aluminium) foil and then place on top of a bare incandescent bulb. 250* F (120*C) -300*F (150*C) will be sufficient.

[@bobbuchanan8466]

I have not used the aluminum foil on the incandescent bulb idea, but I have used the freezer suggestion with success. It works great for a jointer arbor.

[@onjofilms]

I use a 250w laser to warm up the bearings after freezing the shaft in liquid nitrogen. I then use 3 oxen to pull it apart. No WD-40 needed.

[@rolliekelly6783]

The foil just prevents oil or grease from getting on the bulb.

[@kimchee94112]

Good idea guys put one part in the freezer and the other in the oven. I finally figured out why my wife don't want me in her kitchen.

[@chadmartin435]

Great! Now John is going to have to take his table saw apart too!

[@tbac2432]

oh well, I will never know.

[@jdod64]

I love your vids, and your ingenuity and refusal to give up continues to amaze me. Keep up the good work!!

[@donfillenworth1721]

Your ingenuity is amazing! Thanks for sharing.

[@bobuk5722]

Hi folks. Mathias did a great job changing those out. If you have to do it try and minimise the stress on the bearings. Push on the bit that is a tight fit, don't apply force to the inner race to make the outer one fit or vice versa and do not hamer them home - those actions significantly reduce the life of the bearings. As pointed out by others below, warming the housing and cooling the spindle will also help, but you need to work quickly or they just all reach the same temperature. Sometimes a lenght of 'allthread' can be a big help depending on the configuration and conveniently sized mechanics sockets are much used as spacers. But, Mathias, of course, did it with wood! Cheers. BobUK.

[@TheAnimystro]

Huge difference in sound, well done!

[@MrLightPanda]

always love your videos Matthias. I like that there is no ads. Way to go man.

[@vesper1140]

Good morning Matthias, hope you have a nice weekend! Always a pleasure.

[@tiger12506]

I liked your approach to pressing the bearings on!

[@KmanSweden]

Man, you’re brave. I’d be hesitant to try that repair. Well done.

[@IEnjoyCreatingVideos]

Nice work Matthias! Thanks for sharing the video with us.😎👍JP

[@Mucram-17]

Very clever idea with the wood spacers to get bearings back on.

[@sahlind]

I replaced the arbor bearings in my vintage rockwell delta 8" that somehow made its way to Sweden. I had a lot of fun going about it in much the same way as you! :)

[@Dutch1954]

Good video showing improv at it's best. A novice here seeing these kind of videos makes me consider the value of a tool's future maintenance as well as it's utility. It seems in many cases that the simplicity of a machine as far as repair goes outweighs all the bells and whistles you can buy.

[@briantaylor9266]

My contractor saw started making an odd sound just late yesterday. This will be a good guide on diagnosing it.

[@kenl5217]

man that takes a lot of patience to fix it and move the camera around at the same time

[@Ellsmells]

Does anyone else find it really satisfying watching Matthias hit stuff with a wooden mallet sped up?

[@bluesslash3661]

Yeah, the company SKF is about 2 km from me here in germany. Perfect quality :-) Have fun with these......... Greetings from germany

[@martendavies]

Wow great job Mathias!

[@Remaggib]

There is something satisfying about watching him work on things, perhaps the problem solving

Matthias, good the whole sheebang worked out for you on this maintenance job.

[@WiliamBennettwildarbennett]

There's an old saying that goes Dont Force It, Get A Bigger Hammer. Or the one from the Fire Fighter perspective, If It Wont Move, Force It, If It Breaks, It Needed To Be Fixed Anyway.

[@HomeDistiller]

and if you've tried your biggest hammer and its still not working, then the problem must be electrical

[@ProfAlexandreLemos]

You are a wonderfull mechanic improvisation.

[@Kukijiro]

Such a relaxing video to watch

[@Vermoot]

Great insight into your problem solving mind, Matthias :) I would have liked to see the state of the old bearing, if the damage was visible

[@matthiaswandel]

Damage probably very subtle. It was still working, just loud.

[@Vermoot]

Yeah, I kind of figured if you didn't show it, it probably meant it wasn't worth showing. Thanks for the answer!

[@robbaron1206]

Was the blade wobbling?

[@richardsvacuumcenter]

In my experience, when a bearing gets noisy like that, it means the lubrication inside has broken down and dried out. If they have bearing seals that can be removed (the new ones he is using do) then they are able to be re lubricated as long as the bearings have not run too long dry and worn on the inner and outer race causing movement. Hope that helps!

[@MrSatchelpack]

With the amount of work used to get them out, it's better to just put in new bearings and not have to worry about it, especially if they are cheap standard bearings.

[@kaycox5555]

You're an amazing mechanic too? You remind me of my dad. Necessity is the mother of invention, he always said.Blessings to you and yours from the middle of California.

[@danielmackey6594]

I need to do this on my saw... not looking forward to it. Thanks for sharing this new method!

[@barkebaat]

Matthias : When you hit on axels & bearings and such you should always say 'tappety-tap-tap'. I learned that from another Canadian who knows about these thinks. He hates wood, tho' - calls it 'dead tree carcasses' - so he's not to be entirely trusted.

[@Bluswede]

barkebaat That 'other Canadian' is, perhaps, not to be trusted in a 'dead tree carcass' workshop...but, anyone who understands conversational profanity that well, knows SOMETHING and should be deemed part of the national treasure! {grins}

[@fwflyer78]

Good job Matt!

[@KarlBunker]

A great idea, using the threads at the other end of the shaft to press-fit the new bearing.

[@yuyo57]

That’s the type of neighbour you need to help you out. I have a Rockwell beaver table saw you could help me with..nice video.

[@a33795]

I have nothing to do with wood working, never built anything, I just like watching Matthias build and fix stuff.

[@bryancoombesart]

Over the last couple years, Matthias has become my shop teacher.

[@terry2346]

Hopefully I won't need this for a while for my old Sears 113. series saw but good to know the procedure! Thanks.

[@ernestoortega8232]

Exelente Matthias Que bueno que tu mismo le haces el mantenimiento a tus maquinas Saludos

[@danielscheibe8694]

put the bearings in your oven at 120-150 degrees celsius (the grease can take it) and they should slide on easily. saved me hours of bumping and hammering :)

[@matthiaswandel]

and how do I put the bearings in there without putting the shaft that they are stuck on in? Getting the new ones on was the easy part.

[@Oli4vn]

Matthias Wandel an angle grinder solves that problem

[@dennispope8160]

He was replying to installing the new bearings I believe. I usually put the shaft in the freezer and warm the bearings on a 40-60w bulb or just hold them in my hands till warm. Then with the cold shaft and warm bearings the inner race just slides on to the shaft no press and very quick. If it doesn’t seat all the way at the bottom I find a piece of pvc that fits the inner race and hit the inner race down till it seats.

[@AaronNash13]

I can confirm this works really well with putting on the new bearings, I did 200 degrees Fahrenheit and the new bearing slid right on the shaft without needing a press

[@jarodmorris611]

He said pouring the new ones one wasn't hard.

[@mcorrade]

Matt you are the man!

[@jakeed09090]

I'm impressed, that was fantastic.

[@normanboyes4983]

Nice one - but would have been much easier to fit the new bearings by taking advantage of differential expansion - shaft in freezer, warm bearings in oven,

[@dannmarks]

Wrong Bearing in Freezer and shaft in Oven.

[@normanboyes4983]

@@dannmarks You may wish to rethink that.😉

[@grantofat6438]

That doesn't sound easier.

[@bojackson5968]

I just completed this job on a Rexon RXW10 tablesaw, it was almost exactly the same. One difference was I had 2 spring washers on the arbor pin and they were a pain in the ass get to back in, this was the hardest part of the job. Like Mathias I bought the same bearings from Motion Canada at 6$ apiece. I lubricated everything with a graphite spray dry lube. My arbor was a little different in design in that the shiv was one piece. My old bearings pulled off easier and new ones pressed on easily. I need a good idea as to how to hook dust collection up to this saw.

[@blainerueckwald]

I have that exact same saw and also had the bearings go bad. They're a royal pain to change.

[@jimsjacob]

You make it look easy!

[@lucasdJAdam]

I've used a piece of pvc pipe and a glueclamp to press on the bearings. That worked fine.

[@abdeljlilelhoud815]

hello mathias, to push the ball bearings you have to make the hot as it spreads and goes in. do not worry as long as she gets cold again she gets stuck

[@NicoSmets]

That's some courageous hardcore repairing

[@RobertDinTulsa]

Thanks, MW. *I was really surprised that you didn't use any clamps from **2:56** to **3:32*

[@carlospitcher4335]

Great! Way too late but, making a relief cut on the inside of the old bearing avoids it from being pressed. A dremel might do the trick... You are as always impresive!

[@vaalrus]

I fully empathize. I spent a half-day on my back reaching up into my very similar saw trying to get a gear-puller into tight quarters. My saw uses an intermediate pulley between the motor and the arbor, (which has a nice side effect of not having to move the motor when I raise the blade) but that also means it’s a dual pulley, (v-belt+ribbed timing belt style) and this fine “Canadian” made in Taiwan saw used cast tin-foil for that custom pulley. Since I bought the saw, this outfit has gone bankrupt twice, this final time for good, and long story short, after a disastrous adventure in 3D printing, I had a local machine shop duplicate the pulley out of stainless steel, for less than any local shop would print me one out of any sort of nylon or abs. One shop offered to print on in bronze infused stainless for nearly 700.oo. The machine shop did a one-off for 150.oo.

[@trisstaneuteneier4113]

Hey Matthias! Next time you need to change a bearing on a shaft like that, after youve removed the old bearings, just stick it in the freezer for an hour or two. The cold causes the metal to contract and shrink a few thousandths of an inch. Sounds stupid but 9 times out of 10 it works beautifully! Works good for wheel bearing hubs and u-joints and things like that as well. Not trying to sound like a know it all or say your way is wrong or anything. The internets got enough keyboard captains.

[@_bodgie]

Has new bearings improved the arbour runout you tried to fix some time ago?

[@mopemaster]

Yes, but can you do it while repairing a broken cabinet door? 😉👍🏻 Btw. Great Stuff, as always... 👌🏻

[@mpetersen6]

I remember getting sent over to the carpenter shop one time because their Unisaw was making evil sounds. Bad bearings, the arbor was damaged and the pulley was shot. Made a new arbor and pulley, re-assembled, aligned the blade and we tired it up. Smooth, quiet (for a table saw) and cut great. Must of made somebody mad because the Safety Dept came out and locked it out a couple of weeks later.

[@piccilos]

The man owns hundreds of clamps, but still uses his hands as clamps while hammering.

[@rocknumber11]

you are a great craftsman .... tell me if I change a disc from 250 to 210 will there be a problem ??

[@COLDROLD73]

When pressing the races into the hub on my truck I spent about 60 seconds at the bench grinder to turn down the OD of the old race till they would just drop in.

[@CNCSwede]

Nice to see that you use Swedish quality ball bearings 💪🇸🇪😀

[@raimogeel9497]

Hi Mathias, If that nut is moving again, try to find a ring with a lip on the inside that slides in that groove. Put than that nut on again, the ring won't turn so when the nut is tightened put a cold chisel under the ring and hit the chisel, the nut will stay in place.

hello how, I always watch your videos with a lot of attention, and I like them a lot, now let me give you an opinion, for the assembly of the axis you do not have to do as much force or blows, the shaft goes a time at low temperature, the bearings can go in a container with warm oil, then you will do it with olgura much easier, hug! from Argentina .

I learned not to use a metal hammer to drive the old bearing off the arbor the first time I did this to my old Walker Turner saw :-) I ended up using a piece of metal pipe slightly larger than the arbor diameter to hammer on to press the new bearing on. Getting at my arbor bearings was a lot more involved though lol
