Bread-Bakers v097.n008.13

     I think I probably have one of the earlier bread machines made --
     a 4 1/2 year old Hitachi.  It has been used regularly -- probably
     2-3 times a week over the 4+ year period.  Now, the paddle is 
     starting to stick -- it's not rotating properly, and not mixing
     ingredients properly.  I have tried oiling the inside with cooking
     oil and the outside with WD40 oil.  Does anyone have any suggestions
     how to fix this problem?
