Sorry, my friend.  I've spent an hour searching for instructions for how to replace the Kenmore Power-mate belt...no answers on the net for a vacuum cleaner model a decade or more in production??!!  How can this be? and the Sears on line and phone service insist you go to a $ervice location to replace the belt$$$
My New-Year resolution...Never, ever buy Sears products again, EVER!!!
