Thanks Martyn I've not had to work on the steering bearings on my 348 yet, but 1970s Spanish bikes usually have a light interference fit between the stem and the yoke. I just went and looked at mine and it looks the same as yours, which looks like there is a head on the bottom end of the stem. For an interference fit stem, clean up the surface of the stem above the bearing seat. Set up some way to push the stem downwards through the yoke (press/vise/leverage). Heat up the yoke and the bearing. Yoke to just over 100 degrees C. The bearing can be made hotter but be careful to avoid overheating the aluminium. To maximise the effect of the heating to loosen the fit, minimise the heating of the stem. Push the stem down through the yoke and the bearing.
