Panasonic Breadmaker SD-206?

Panasonic Breadmaker SD-206. The turning part of the base in the body of the machine that the bucket fits into is making a noise when turning, like there's an obstruction in there. Is it OK to unscrew these workings? The piece in question is circular, black with two lugs on it and is about 5cm diameter. It sits in its own larger metal house which is attached to the base by 4 x crosshead screws. Does that indicate it's OK for me to remove them?? Thank you.
