Garage Door Opener Fix

Product arrived quickly and with easy to understand instructions. The parts are high quality, and it took about a hour to remove and install new parts. Opener works like new again, and it only cost twenty dollars compared to $150+ for a repairman to fix. Awesome!

Excellent, quick, perfect service.

Everything was perfect. Received door opener part the next day. All the instructions were very exact and easy to follow.

A reasonable purchase...

A reasonable product at a reasonable price. Delivered as expected, working fine after installation, etc. I read where someone gave kudos for the instructions...I wasn't all that impressed, but that's a nit b/c this really isn't rocket science so you should be able to figure it out.

I learned some things with this overall experience though. First of all, I was surprised with the original garage door opener product -- that there'd even be plastic gears in these things. But after that revelation, I now realize how important it is that you keep the garage door system lubricated as I am certain that the absence of that is what caused my drive gear to get so shredded! I have since come across an advertisement that says something like "if your garage door is noisy...you're headed for trouble and need to lubricate...". Duh! Wish I'd have paid attention to the noise before this happened!

PS: When putting it all back together, pay attention to the orientation of the topmost piece that you are screwing the driveshaft into -- if it's not placed appropriately, you cannot attach the sprocket cover. To remedy, you have to backtrack quite a bit!

May be a little overpriced?

No problems finding what I wanted on-line. Promptly shipped. The only part I really needed was the driven gear. Adequate directions for disassembly. Overall happy with the purchase.

Just what the garage door opener needed...

When the main nylon cog in the Craftsman garage door opener split in two, I expected the worst -- time to replace the opener. Had I known that the cog was made of nylon (like others realized), I would have been greasing it annually. Doing so is a matter of removing the cover with a screwdriver and squeezing some grease in the teeth of all the working nylon parts, simple. Worth it compared to the ~4-hour, two-person job of pulling the opener apart to get at innards you need to replace. That the cog would dry out and snap after at least 15 years of no maintenance...go figure!

If you're guilty of similar neglect, this is the perfect kit to save yourself a few hundred dollars and the perfect project to put your dad/close friend to work. Even better, you're left with extra grease (enough to grease your other opener and the one you're repairing this time and a couple more later).

There were some frustrating steps, though. Removing the pins wasn't too tough if you have a punch. The part that drove us crazy was how to get the (don't remember the part name) almost-round, metal part with the notch off the stem where the worm resides. In our case, it didn't simply slide off (probably tight from the metal-on-metal contact/oxidization of 15+ years). If you get the same, hair-brained idea to drive the stem out with a hammer/hammer-punch combo (hopefully your solution is more elegant), be prepared to lightly file down the edges on the end of the rod where you were making contact; otherwise, it won't come off.

Also, after you get it all back together and are making the lift adjustments with a lot of opening/closing, don't be surprised if the opener suddenly won't respond. Relax. It's likely not broken again, just overheated. Give it a few minutes (apply beer, take deep breaths, you don't have to start over), then finish your adjustments.

Lesson learned: Keep the working, nylon parts in the garage door opener well-greased!

Highly Recommended

Package contains more than what you need. Replacement is fairly easy. I did not follow the instruction exactly. Some steps don't apply to my unit. The only difficulty is to remove the pin from the shaft. You need a hammer and another solid pin to knock it out. Don't knock too hard to bend the shaft or damage the bearing but hard enough to remove the pin. Hold the end of the shaft while knocking would prevent damage. I used two fingers to hold the pin and the rest of the hand to hold the shaft and the other hand to hold the hammer - a challenge job. Now the door opener works like a dream. By the way, it is over 15 years old.

just what we needed

The shipping was lightening fast and the parts were at a fraction of the cost elsewhere. Thanks for getting our door back on track!
