My Sears 1/2 horse chain drive opener finally bit the dust. It has worked for 17 years with only one inexpensive gear replacement, but now the drive shaft bearing has worn through the housing and it's time to pitch it.
My instincts will tell me to stick with the same type because of my good luck with it, but there are other choices.
Screw drive.........Will the screw or nut wear out and require a costly repair?
Belt drive...........Sounds good but does the belt last? Is it expensive to replace the belt?
Any advice would be appreciated.
