Carlos V Moreno Valley , CA January 09, 2015 The drive coupler was damaged I simply unscrewed the "reverse threaded" coupler and replaced it after watching the instructional video. Great job on the video you provided. I wouldn't of known how to take off this piece if it wasn't for your instructional videos. It made my repair much easier. Thank you.
