  • 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!

    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.

    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

    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

      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.

      Hi, I know it's a long time ago, but were you worried about melting the alloy of the head stock?

    • @Askor200
      @Askor200 Před 3 lety +1

      @@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.

      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.

    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.

      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

    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.

    • @Aussie50
      @Aussie50  Před 6 lety

      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.
