Thanks. Got new bearings (Timken) from BearingKing. Remarkable - play barely perceptible.
Old ones came out quite easily, gentle drifting. But to replace -
has anyone tired the oven versus freezer system please?
In over 50 years of replacing this kind of taper bearing, i've never done anything BUT gentle tapping/drifting to replace the outer races. I've never cracked a race yet! So long as a modicum of care is used that the drift doesn't slip and scratch the bearing surface, you are good to go.
I once changed out a similar design of front wheel bearing on a 60s Austin Westminster at the side of the road on Salisbury plain on a Sunday evening, armed only with a hammer and a knife and fork (Jack and wheelbrace too, of course, being pedantic!)
