The pdf parts and service manual was a great tool. While I was waiting for your response I was reviewing prior google searches for the K45SSWH Kitchenaid Mixer. This link did have the correct rpms at each setting for my old Classic model as the rpm at "10" is a bit higher @ 280 and a brief outline of how to perform the adjustment procedure. Here is the link.www.fixya.com/users/thaehnguyen2 . The pictures within your pdf were very valuable while performing the procedure and the entire doc. will be a great resource for future repairs. That said I feel more involved repairs to the motor itself I will take to a local service technician.
Many thanks again,
