Removing Taper bearing outer races with a tig welder in a lathe, car etc

- Pretty standard procedure to remove the outer races from a blind hole, where you cannot press them out. use an Oxy torch, Mig or Tig welder to melt and shrink the metal. Tig seems to be the cleanest tho, far less chance to contaminate the area with metal spatter.
AVE shows how its done (or not) with a Mig welder! . its messy!

the joys of thermal expansion and contraction. Bearing races are many times press or freeze fit.
Hold on to those old bearing races. You can use them to help install new bearings of the original size without your pusher tool getting stuck.
When I've done automotive automatic transmission work I used the old bearing races, ever so slightly ground-down on the OD, for just this purpose. Someone welded them to a length of pipe and we used a small sledge hammer to knock 'em in.
Pretty neat little trick, definitely will come handy some time!
I always did the job with my mig but as you say its messy, I have some BMW steering head bearings to do so will be trying the tig out. Thanks for the tip.
yeh just clean out any grease and grime, zap them in at least 4 places and they should fall out without the messy spatter of a mig or arc welder.
or run the bead around the inside rather than stitching it, just do a full 360 with the torch and it should collapse in when cooled
@@Aussie50 year running a full bead was my usual method but having tried the four spot system I believe that to be better. Job done. Many thanks, forn freezing Scotland.
Polyurethane instead of oil, OUCH! Wouldn't want to be the student that did that!
I did this last thursday whilst replacing the steering head bearings on my wr450f! Worked a treat
Hi, I know it's a long time ago, but were you worried about melting the alloy of the head stock?
@@garycrofts1421 not at all as aluminium is a great conductor of heat - it dissipates into the bulk of the surrounding metal before any localised areas get the chance to reach melting point. That said, you definitely could do some damage if you held a torch on there for long enough! Just keep a reasonable pace and it will be fine.
@@Askor200 thank you 😊
the hours i have spent trying to get a race out, brilliant :)
I see you too have been watching way too much AvE, and have started picking up on his catchy lingo. I've got a badly worn wheel bearing in my Lexus and I'm not sure if the bearing will come out as a unit or fall to bits as soon as I reef on it, so this little tip will come in handy
yeah I used to blow them away with oxy and make a mess until I saw AVE's explanation
Here's a poor man's solution: I had a race in a Jeep rear axle housing to remove, no welder, no way to move the Jeep. Took a can of Air Duster, turned it upside down, sprayed the race until it frosted over, put on a glove and pulled it out by hand.
Neat trick. Can't wait to try it. Thanx Bro'. P.S. Make a 'puppy' video. I'm sure most of us would enjoy it.
I was down your way this arvo. Old mate at the yard said ‘oh you mean gyro!’ Haha
Good trick on the bearing. Frankston bearings never seem to have anything in stock. Just my experience.
Haha yeah I missed you by a few mins from what I heard :p. if you want to catch up let me know!.
I miss having CBC around here, but since the steel mill closed most of its operations they had to go. Frankston Bearings is my next port of call, not too bad, but as you say, they often do not have what you want.
For those who don't have access to TIG, the alternative is the newspaper and grease trick that's been demonstrated by Uncle BumbleF3ck (seeing as how you paid tribute to his uniquely awesome lingo in this vid).
Good one. Awhile back I needed to cut a thick chain link. Working on the road I had no cutting tools. So I fired up the stick welder cranked the amps up and burned through the link
Nicely done.
That’s so perfect, save lot of money to buy the properly removal tool. Thank you.
My work with old video professional videotape gear requires bearing work every once in a very long while, smaller bearings of course. I think the last time the last time there was a big problem removing a bearing, the guy I was working with and learning from (who know what he was doing) had to try many things and it ended with a piece of thick steel made into a jig, then there was a big hammer and then there was a torch. And then the visit to the local bearing place and it was all fine and good.
DoubleBoost has shown this being used a few times to great effect. Awesome channel too tbh.
Just throw the new bearings in your freezer for about an hour and they will fall right in
Thanks for the vid, sure I will use it!
Damn that arc is bright. I'm sure you'd need to wear eye protection when working with a tig welder.
Dry ice my old motorcycle trick .😊
Im jealous. I'm so damn keen to obtain a Mill and Lathe.
thats an awesome tip, id like to give it a go with an oxy
Thats awesome!
Hmm melt the metal and gain a tiny diameter drop, sneaky :-D
Was going to ask what your opinion was on those little mag mate welders.
I hope curie was outside when you were welding.
oh yeh she gets closed out of the shed when I do anything that could be harmful to her, IE welding, grinding, high voltage etc
I did wonder what the gummy shmew was but that explains it !!
Son of a diddly
Hey do a update video on the Doom ATM.
old school
This is handy and I may use it at some point. But I wonder why nothing really sophisticated exists for the job. I mean the technology is two hundred years old but we still scratch our heads how to best get it removed.
I guess it's easier than blasting the thing with a CO2 extinguisher to shrink the metal down, cheaper too I suppose... :P
You know those air duster things in a can? Tip one of those arseways so it sprays liquid instead of vapour, and the thing you're shrinking snap freezes, because there's all sorts of anes like propane and butane and other hydrocarbons that go bloody cold when exposed to air
Do you think a stick welder with a carbon gouging rod in the hand piece would get the job done?
as long as you melt the base metal it will work, its just a matter of how much of a mess you want to make. Tig seems to be the cleanest.
Yeah, I thought it might be a less messy alternative for people like me who don't have a TIG welder at home but it might spit hot metal everywhere too
Not that I can talk but seems like even after just a minute can get some sun burn, biceps seem most susceptible, legs u can't really tell but I'm sure they cop it..., I've really gotta try harder when it comes to PPE
Robot with a goaty
So you didn't use any Argon with the tig? I couldn't hear any post flow.
I've got a tig/mma/plasma machine, if I don't need to rent a bottle of argon I will give it a go.
I used argon, I just have the post-flow turned right down to save gas, tig electrodes burn up instantly without gas. as opposed to rental you should be able to buy a bottle, its a bit of an inital outlay but if your not using a lot of gas, and the cylinder sits idle for long times, buying is best.
PU instead of oil? Sounds almost deliberately!
Bit close with the head mate... I think AvE would call you a smoke eater :) and as "Reflex Photography NZ" said, plagiarising some of his lingo hahaha but good to see some of your old school vids back mate.
