I hae a noisy Genie operated garage door mechanism. It has a screw type
drive shaft rather than a chain.
What should I use to lubricate the long 'screw" and is there anywhere else I
should be lubricating ?
on my old sears screw drive garage door opener i had to removed the
screw drive and take it to the back yard and spray it with some Brake
Cleaner to get the old grease removed..... got it clean down to bare
metal as the old grease with dust/dirt on it was like putty and when it
was cold the garage door opener would not work too good.. would always
hang up and not open all the way or not close all the way... fixed it by
removing all the old grease.. i quick fix was to use WD-40 to thin the
old grease off.. WD-40 is really a solvent and will also remove old
First thing that came to my mind was white lithium grease in a spraycan.
You're right, though, to take the screw drive out and clean it. Brake
cleaner is good choice. WD-40 doesn't last very long as a lubricant, and
likely isn't clingy enough to be the only lubricant on a screw drive.
Most stores that sell openers will also sell you a tube of lubricant. Get
use to doing it, it's a yearly thing. I dumped mine and bought a belt drive.
Shoulda done it 5 yrs ago. Don't use regular car grease. it gets too thick
at cold temperatures and binds the mechanism up. (uh...not that I did
