I took apart my hoover carpet cleaner?

I took apart my hoover carpet cleaner looking for the belt to change and I can't find it, only the cover of the belt housing. Also it's been some time since I dis- assembled it and forgot how to put it back together? I'm mechanically inclined, I work on my own car, but when I picked up the steamer to assemble it all the parts that I had together all fell off the machine! Can you send me a diagram or something ? Hoover Steam Vac model # 5907-900 purchased in 2003 Thank You
