Looking for opener opinions. Belt drive? Chain drive? Screw drive? What is your experience? My chain drive Craftsman is 15 years old and motor bearing is failing. Should I stay with chain drive or is something better?
I had a chain drive Stanley that certainly did the job, but I moved into a new house (18 years ago) that has a Genie screw drive. It has been very reliable (gone through 4 hurricanes and countless Forida power surges) and it is very smooth compared to the chain drive. You should find someone with a screw drive and run it up and down a few times and see if you think it will suit your needs.
Ditto on the Genie Screw Drive. I replaced my chain drive after it quit with a Genie Screw Drive. It is super quiet and really fast. It was also very easy to assemble and install. If I ever have to do it again, I will buy the Genie Screw Drive again in a heart beat.
Why would you not just replace it all? Sounds silly to me to even consider adding a new power unit to an aged drive system. Replace it all with a good Genie screw drive and you will be trouble free for mant years to come.
