Hi Dave,
I second Kevin's suggestion -- using a heat gun on 1-4 hammers at a time, then plucking them off with an hammer extractor plier. At least on the Hamburg grands, that method works well and it is very fast. I haven't timed myself, but 10-15 minutes? In that ballpark.
I used to share Wims concerns, but when I started using the heat gun I found that the whole procedure can be done without stressing the centers. With the right amount of heat applied, the hammer heads come off very easily; so easily, in fact, that you can stabilize the center with one hand and use the hammer extractor plier with the other, if you prefer.

Replacing hammers on a D, and needs to happen quickly. What's the best way to remove D hammers, keeping the flange & shank.
What kind of the glue does the factory use? Will using a heat gun help?
I've always used the typical plyer hammer extractors, but those can be forceful sometimes. And doing a whole set can be harmful.
