I know there are a couple of experienced garage door opener experts in the group. I have one ancient Sears one that ate its gears, and a twin in the second garage that it headed for the same fate. They are about
25 years old, and replacment gears are no longer available, from Sears, or Chamberlain, who made them.There's quite a bit of perfectly useable hardware all set to go. What I was wondering is if I have a good chance of being able to replace just the main drive box, while keeping the rail & such in place. I looked at some new ones at Sears, and the rail/carrier design doesn't appear to have changed significantly. I could go cheap & just get another chain system. The alternative (assuming they use compatible rails) would be to go for a belt drive system to get something a bit quieter.
Is this a possibility, or am I pretty much stuck with replacing the whole shebang? Any other suggestions or comments welcome.
Thanks!
