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 received the garage door rollers. They were exactly what I ordered and shippment was faster than I anticipated
So far this company did exactly what it said it would do even with two holidays during the time
I have not installed the rollers yet due to bad weather but they are a match size wise, my old worn out rollers were steel with bearings. These should be a lot quieter,which I am sure the renters over top will appreciate
