Fix tape adapter / Constantly ejects

Why is the rubber piece so important?: Sometimes, it's just too bulky. When making contact with other cogs, the bulkiness prevents the piece itself from spinning, which stops the movement of the other cogs. Being one of the few pieces with rubber, the other cogs rely on this specific piece in order to move.

It's not working. What else can I do?: If your car persists in ejecting the cassette, you may want to take the rubber piece mentioned and rub it against a surface, much like a eraser on a table - to smooth it out more. Just make sure you don't accidentally make it uneven.

NOTE:
-Removing any of the cogs won't work.
-If you choose to lubricate the cogs (which I strongly don't recommend), do it SPARINGLY to whichever pieces you're applying it to.
