Got an old bike that has this piece in between the crankset and the frame. It’s very loose and keeps rolling around and getting in the way of the chain when I pedal. How can I remove it or make it stay fixed in one place?

can confirm, this is for a chain guard. if you are going to remove a crankset/arms, it is best to use a proper crankset removal tool. the last thing you want is to fuck up your crank arm or bottom bracket and have a malfunction during a critical moment aka any moment you are on a bicycle. i had a friend’s crank arm strip as he was riding into a 4-way intersection. scary times.
anyway, never hurts to invest in proper tools for your bicycle. if that’s not viable, take it to a local bike shop & ask for help. they might do it for cheap or even for free, since it is causing a safety issue, or you can just get a new chain guard.
