this may be a really dumb comment- I am assuming that the gears and ball bearing are inside the part as shown and are included in the assembly price. Is this correct?
Your assumption is correct. All the gears and bearings are included in the 753-06571 gear box assembly.
Is this part the same as 753-06571 that is used on a Craftsman weed trimmer? The part looks the same but that doesn't mean much.
You can consider yourself safe in ordering part number 753-06571 for your Craftsman trimmer. It's probably made for Sears by the company that manufactured that one.

You are correct. When you order part number 753-06571, all of the items shown in the image are included.
Hope this helps,
