Solid wooden 16 foot, four panel garage door. Replaced the springs, cables and adjusted track. In the past 15 years replaced two openers both Sear 1/2 hp. The problem is the nylon gears strip out, on the Sears chIn drive.
Now that could be because the weight of the door and the weak springs and the limited 1/2 power.

question.. I have three options.
1 1/4 hp belt drive
1 hp screw driven drive
3/4 hp chain driven with nylon gears

Anyone have a screw drive opener or a belt drive?

Screw Drive is always better than chain or belt, little more expensive usually but worth the difference in life cycle cost.

One other thing but minor...you do have to lube a screw drive appx twice a year to reduce noise but it's a 5 min job.

Screw drive is the way to go.

This door required 300 pound side springs so the door is very heavy, I know the side spring provide the addition lift and lowering tension is the 1 hp screw drive type good with that weight factor.

Depends on the hp but the recommended Mgfr rating will be listed.
