Bread-Bakers v097.n031.7

  After hearing terrible noises coming from the machine - I finally found
out what the problem was.  In the base of the machine itself is a black
plastic disk with 2 upright pieces that turn the rod on the bottom of the
pan that turns the paddle.
  Well, I must have not seated the pan properly and the uprights are
shorn off.
  Does anyone know if the black piece comes out and can be replaced?
Where would I get a replacement part.  I appreciate any help with this,
thanks.
