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.
After having a LiftMaster door opener installed in my new garage/shop, I soon realized that the HomeLink system in our '02 TrailBlazer would not synchronize with the new opener. I researched the pairing issue relating to my new door opener and discovered that I needed to install a bridge (repeater) to update to the current wireless control signal encoding. I ordered it, installed it, paired it, and it works as advertised. Fast ship, great price, and easy install -- pretty much Plug & Play!
