Ahh I see, yea it shouldn't be an issue.

But in my experience, viton o-rings have been hit and miss. Mostly due to size variation.....but the one's I've seen fail or smoke, due so in short order. Not saying thats your problem, but I *have* known them to be a mix bag.

EDIT: Another possibility that happened to a local member here last year, involved the springs. He'd instaleld one backwards, which allowed the assembly of ring and scraper to turn on the rotor instead of locking it down with the tabs on the spring. Are you positive that they are all facing the correct direection AND oriented with the flat tab UP, round tab DOWN?
