Close inspection shows the wear on the bronze bush - there’s a swarf edge on the lower edge and the top edge has taken the shape of the o ring , being removed below

So you can see clearly the extent of the top bush which is to be removed.

I cleaned out most of the old grease then stuffed a clean tissue into the tube below the bush to catch the waste that will be created


Using an old chisel I cut two parallel score marks down the inside of the bush about 10 mm apart

Then carefully tapped a small bradawl between the bush and the shaft between the scored marks and broke out this section of the bush in stages
