Personally I am quite leerly of anything putting a lot pressure on the crankcase. And these adapters can be really rust fused at times that why when I can I use a bearing separator/puller setup. I have the stripped out a few forcing screws even when using heat to expand the adapter connection.
When they are stuck this bad I know I am going to need to replace the adapter or pulley most times so I go ahead and order the new replacement part. But now I don't have ready access to takeoffs either.
