Parts and instructions work well

Review by The Clover, 2010-05-23

The parts arrived on time and were as ordered.
All the parts I needed were included and some parts were not necessary to fix my opener. My opener is more than 15 years old. The instructions did not match the configuration of my unit, but the concepts were the same and I was able to accommodate the differences once I understood the general procedure, the order of events and the components of the mechanism. It took about three hours to do the complete job, including small adjustments to the door open and door close stops and getting the correct tension on the chain. I completed the repair three weeks ago and have cycled the door at least 20 times, including the five test cycles. Everything works fine.

easy fix but be careful

Review by Joe Deasy, 2010-05-18

If you are mechanically inclined, this kit offers an easy way to extend the life of your garage door opener. Just be careful because door openers can cause serious injuries. Do it right the first time, because the second time it will be much harder if you are missing a finger.

These parts, along with the instructions, provide an easy fix for what is arguably a defect in this popular door opener. It's obvious that the cheap plastic gear is the weak link in the machine. As I suspected, I only needed the main gear, but for a few dollars more, I ordered this kit in case I needed something else. Now I've got extra parts that I dont need (yet), but I would definitely do it the same way again.

I was able to skip most of the instruction steps (because I only needed to change the main gear) so it took me less than 30 minutes. If you need to change the worm gear, it will take much longer.

As advertised

Review by Roy Stone, 2010-03-25

It's great to be able to find such replacement parts without having to deal with Sears. They don't back their products and look for any way possible to avoid doing so. Even if a potential safety issue has been documented many times they refuse to accept responsibility. It takes actual personal injury or death before they "might".
