Steel bushes, the best way to remove them is to run a few runs of weld the whole way around the inside of the bush, once it cools they will shrink and knock out easily.
For fitting the new ones id recommend one of these hollow core rams.

This is a fairly good deal and ideal for the workshop.

Get a good peice of threaded bar and a few plates to pull the new bushes in with.

You can also remove some old bushes this way by pulling the old one out with the new one.

I find a straight grinder with a flap wheel or spira band is handy to give the hole a quick clean up before fitting new bushes. You can never have too many hollow jack's and collars and spacers and bits and pieces to rig up for pulling and or pushing bushes.

Same cylinder I use... But a hand pump as I was too tight to go with the air version. 30T seems a handy compromise they are heavy enough to hold at that. Good threaded bar required too! This is my choice method for removal and installation, makes the job a dream really in comparison to driving them out and in with a hammer.

keep all old bushes and bearings for spacers and pulling/pushing bosses ... unless totally banjaxed ... inner / outer races make good spacers / sleeves

Steel bushes, the best way to remove them is to run a few runs of weld the whole way around the inside of the bush, once it cools they will shrink and knock out easily.

This technique works really well for bearing races, particularly where access is limited.

As a variation on a theme, a cm or two of weld on an inner race will give you a "soft spot". Hit this (the weld) with a cold chisel a couple of times (lined up axially with the shaft). The race will open up and fall off.

seen this on YouTube and was curious to see if it worked froze the bush but no where near what was required to fit it. Wasn’t a big bush as well.

need a good pair of gloves to pick it up after

 

[Bri963]

Pulling in I‘ve turned up top hats with the flange 0.5 mm less than the Bush OD, 10.9 threaded bar and a battery gun. I’ve also lobbed them in the freezer. Can’t beat that for price.

 

[Quattromike]

Needs a good while at low temperature to soak into the core of the metal and gets best results.

 

[Bri963]

Put the top hat in the fridge overnight as well, slows down the Bush warming up.

Shove a breaker on a 1t mini, freeze the new ones

I have adaptors turned up for a 20kg breaker for all sorts, from bushes to ball joint splitters. Twenty seconds of that is equal to a lot of hits with a big hammer, and much less work. Used it two days ago for ball joints whilst changing the diff on my ranger.
