Bearing race removal

[Paulpen]

Paul, get yourself a good length of hexagonal stock bar, a decent sized hammer lump / sledge, heat the axle tube around the bearing track area and Robert's your mothers brother, or alternatively a length of tube, eg. scaffold or round solid stock that is slightly smaller in diameter than the id of the axle tube so that it slides inside and use the same method, the beauty of using the tube method is you have a full 360% bearing on the backside of the track and therefore will be knocking it out square as opposed to at an angle. simples....

Do you mean heat the outside of the axle and then tap it to loosen if off inside ? If so where does the hexagonal bar come into play ?

This is what im trying to get out :

Ok, the hole in the axle tube goes straight through from one side to the other yeah.....? then you need a piece of barstock or tube to slide right through from the other side till it hits the back side of the bearing track, then knock it straight through till it comes out.

I see where you are coming from but the axle is 6 foot long and the centre section only has that inch diameter hole. Combine that with the thin wall of the bearing and I cant see me being able to find anything to get a good hit on it with to be honest

 

[Pete.]

Hard to make out what's in that hole - is it just the outer race of a taper roller wheelbearing?

 

[brightspark]

bronze bush isnt it

 

[Paulpen]

bronze bush isnt it

Basically thats what im lead to believe it is along with white metal bearing, plain bearing, journal bearing, outer race etc

So im not really sure what its called

You could cut a bit of thick plate to the right size and shape so that it's possible to push it through the race and then turn it around so that it bridges the tube with the ends of the plate resting against the back of the race. Then use a drift from the other end of the axle, pushing against the centre of the plate.

I see where you are coming from - a kind of rectangle with mooned edges or something along those lines maybe ?

Would just be the getting it held in position that would be the hard bit...

Yes, I was thinking of a disc with two parallel flattened sides. You could weld a bit of wire to the middle so that you can poke it through then fiddle it into position.

I do like you thinking !

Ill try and find something sutiable to poke through from the other end first before I go putting things in the hole but now ive got some plans

Maybe like this

 

[Paulpen]

Maybe like this

Awesome !

Then I can bring heat into play if needed

Many thanks to all

Or use the oval disk with an oval hole in it. Put a bolt through it and insert it in.

Then a plate over the end and use a nut to pull it out.

Would get it flush with the end, the rest tends to be easy.

 

[Pete.]

Or a home-made slide hammer. Get or make a big fat washer and cut the sides off so it fits through the bearing then cut a slot through it. Take a piece of bar and cross-drill it for a heavy bolt or pin, then put the pin through the bar and weld it to the washer slightly off-center so the washer can tip. Poke it thorugh the bearing and when you pull it will sit flat on the other side. Now slide a heavy weight over the bar and weld a flat plate on the end, use the weight to hammer the bearing out.

 

[Paulpen]

Many great ideas

Ill be attacking it after boxing day so you will all know how well or how badly I got on before new year lol

 

[bigtip]

i think i've got an understanding of what the set up is but i may be wrong...

if it is how i think it is, i would get a long lentght of bar, with a good sharp edge on the end not previously battered or bruised, and get someone else to eye-up when it hits the back edge of the race. they say 'now', you whack with a lump hammer. move to the other side of the race, they eye it up again, they say 'now' again, you whack again.. shouldn't take too many whacks to get it out.

then get a new axle that doesn't have such a pain in the **** bearing

 

[Paulpen]

Youve got it but im not sure due to the small inner hole if ive got enough angle to get on the inner edge of it yet

 

[outofthefire]

As a last resort you could weld all the way round the axle on the outside it would put more heat in than a propane torch and might help to free it.

 

[paul_f]

I did something very similar to Pete's suggestion except I just had a hole in the centre of the round piece with two flattened edges. I used threaded bar with a nut welded on the end behind the washer and then used a very large socket on the end as a spacer and pulled it out by winding on a nut

 

[arceyered]

If the bearing is only 2mm thick and you can't get to the back to tap it out or get a puller on it , then i would agree you will more than likely have to cut it out.
you could also try? drilling two holes 180 degrees apart and deform the bearing behind a puller plate or drill through the bearing and use a tie bar ?
Or if there is enough space forward of the bearing fit a new one and leave the old one in situe.
