I'm glad you asked Bobby, after getting everyone's opinion there was no way I could salvage the old motor for a reasonable cost, so I bit the bullet and installed a new motor I had laying around. I really hated like hell to do this, as it gives the machine a different sound. The original 2.8 amp motor took a little longer to get up to speed and wasn't quite as powerful, but it also wasn't as noisy. Personally, the more energy efficient a cleaner is, the better. New Orecks have a 4 amp motor. I do have other 100C's in my collection (we would see them from time to time as trade-in's at Oreck - I would only bring them home if they still had the original perforated vinyl outer bag), but this was one of my earliest examples and it is in mint condition. You're probably right about the transmission being better in the Concept 1, I just thought this was when Hoover started getting really chintzy making the machine with a plastic base.
