Bought from A for a good price to replace the factory one on my Cummins coal compactor. The factory bearing had a bad pulley bearing, and instead of just replacing the pulley, I ended up with the entire assembly for not much more than six packs of Keystone. It takes a half-inch ride over the factory to clear this. Dayco needs 3/8. I saw where others claimed it was made in the land of the Chinese. The box says "Made in China" but the tensioner clearly says "Made in the country of the eaters" (Turkey). I would buy it again if I needed it. Just over half the cost of A Zone or Oreilly.
