How would you remove this flanged bearing?

Paul:

Not sure if what I'm about to suggest will work, or if you have the space for it, but in auto bodywork there is a tool called a slide hammer. It's basically a long (2') rod with a weight that slides on it. With bodywork, you drill a small hole, thread the end of this tool into it, then bang the weight against the far-end of the tool, and it impacts the dent out.

I'm thinking you could weld the correct bolt on the end a slide hammer and pull it out that way.

Solved! Lots of Kroil, a bearing removal collar and a crowbar!

If you don't have a puller, one can easily be made, see illustration. 

Make a square  "U"   shape steel puller with a hole drilled in the center.   Top Width at least wide enough for the legs  to clear the bushing.

Hole must be just large enough to allow bolt to pass through. 

1/8th or 3/16 inch steel strap will probably be thick enough.  Us strap steel about 3 bolt diameters wide.  If the top starts to bend down when pulling, put a short piece of your strap steel with a hole drilled in it.  Place it between the washers and puller.

get a long threaded bolt, nut and a couple of flat washers.  The thread size should screw into the flanged hole.

1.  thread the nut onto the bolt most of the way up the bolt head

2.  Grease the washers on both sides and slide them up the bolt to the nut.

3.  Grease the length of the bolt threads.

4  Place the bolt through the top hole in the "U" shaped puller and thread it into the flange at least one bolt diameter in depth.   The nut and washers are on top of the puller..

5.  Use a wrench to tighten the NUT down on the puller, turning clockwise.  If the bolt turns, place a wrench on the head to prevent it from turning.  this will pull the bushing out.  If you run out of bolt thread before the bushing is clear, spacers can be placed under each leg of the puller to extend it.

Materials can be obtained at Home Depot or Ace  if you don't have them laying around. Excluding parts chasing, it should take a half hour to make.  Remember, this isn't going to the moon,  It can be a little sloppy and still work.  A torch will help form the puller, however you can bend it in a vice and a LARGE hammer.  Grease on the threads is the key to geting a smooth pull.  Finally, if it is really hard to pull, a propane tourch heating around the perimiter of the bushing will expand the outer area around the bushing to get 1 or 2 thousands  clearance.  heat should not be over 200 - 300 degrees F.  A good Spit and Sizzle.

Paul,

Assuming that the bearing is accessable only from the side shown:

Use a socket wrench socket that is larger than the outside Dia. of the bearing, A threaded rod, washers and a nut.

Thread the rod into the bearing fully engaging as many threads as possible, slip the socket over, centered around the bearing  then washers and the nut.

Using a torch heat the bearing end of the structure and carefully tighten the nut . 

If the bearing is accessable from both sides of the structure use a small socket same size as the bearing to push it out using the same method and a bolt long enough to span both socket and the bearing.

Those are both brilliant suggestions. Thx.
