Is their air trick to getting these out / special tools required
Or just a drift and gentle persuasion with a hammer all that is required
Did mine recently. The bottom will drift out from the top and the top from the bottom. Don't hit the two abutment rings that sit in the frame on two ridges in the frame. These rings locate the cups and do a good job. Look at Dragonfly's parts breakdown it will explain a bit more. You can re-use the abutment rings. Hope this helps.
