I have been removing the bearings from the top arms tonight and have been welding an m10 bolt head into the top of the bearing then pulling it out using a socket, washers and a nut, now this worked fine for 3 of them but the 4th one the bearing has broken up leaving just the outer race  in the arm. How do i get this out without causing damage to the arm?

Using a drift tap it out from the other size. A slight angle on it can help get purchase.

Preferably a soft drift made from brass to avoid damaging the arm.

Will I be able to reach the bearing back edge from the other side? Don't know if my brass drift will fit through either.

 

I did think about carefully cutting a slot with a junior hacksaw blade so that I can get behind the remaining outer race.

Try a dremmel if you have one. Mart.

Hi Andy,

 

If you have an old flat bladed screwdriver that's long enough to reach the bearing cage from the other end you could use this. I had such  as screwdriver, and ground the sharp edges off of the tip before using it. Just use light hammer force to gradually tap it out. Just be careful not to dig into the arm metal surface where the bearing sits.

As mentioned above, a brass drift is the best thing to use as you'll not damage the arm bearing surface with this.

 

Cheers, Steve.

My problem is that the roller cage has broken up and i'm only left with the very outer part of the bearing that sits against the arm.

Using a dremel is ok, just make the outer part thinner, then you should be able to pull it out using a pair of pliers or gently tap it out using a steel bar and a small hammer.....  gently being the word to focus on here.
