The complete gear kit was exactly as described and included everything needed to overhaul a worn out assembly. The link to the YouTube video was indispensable. The only small glitch was that the video didn't emphasize was that the plastic sprocket dust cover mounting holes require that the assembly be installed so they line up front to back. I put my opener all back together only to find that the dust cover holes were not where they needed to be. Had to fabricate my own little dust cover from a plastic cup and double stick tape it to the unit. Not pretty but it does the job. Small complaint.
I had a travel control module fail in my electric garage door opener. Bought a replacement on line and it fixed the problem. Came with easy to understand instructions and I had the opener repaired in no time. Great price too.
