Bernina 180 Bobbin Case Housing Loose
My bobbin case housing is loose. It moves back and forth causing the bobbin thread to bunch up. I removed the needle plate and the bobbin case. I can move the mechanism that holds the bobbin case with my finger. It doesn't turn around. I can make it click back and forth very slightly with my finger. How to I get in there to tighten it up?

The housing you are pointing out is the rotary hook asm. This is suppose to have a little clearance there, the clearance allows for the lower thread to come up. In order to make the machine run smoother in that area, is to put a drop of the benina only oil
