Exactly what I needed! My kids managed to open the garage door while our van hatch was opened and the door got caught on the hatch, breaking the chain drive gear right off. Thank you for posting exactly what I needed. I just finished installing a new one I got off of Amazon.
The sprocket broke while my garage door was opening. It was approximately three-fourths of the way open, and it slammed down. The chain was hanging. Once the sprocket and chain are replaced, does the door need to be balanced????? I was told it had to be re-balanced at a cost of $229. Please let me know if this is necessary. Thanks in advance for a response
It sounds like the torsion springs broke, if that is the case, it would usually be part of the cost when replacing the springs. If your total bill was in the neighborhood of $400-$500 that would sound accurate for a total on parts and labor for the ENTIRE job not just balancing, I hope that makes sense.
The springs were fine. The gear/sprocket broke. So he replaced the gear, reattached the chain, reset it and then balanced the door. He said it was necessary to rebalance the door. Was it necessary to rebalance the door?
@@KathySuePeré If I am understanding you correctly and we are using accurate terminology, then no. If the torsion springs are still in good condition and haven’t been adjusted, you typically won’t need to rebalance the garage door after replacing the sprocket and chain. The sprocket and chain are part of the opener mechanism, which assists in lifting the door but doesn’t affect the balance directly. The torsion springs are what counterbalance the weight of the door, so as long as they’re set correctly and functioning well, the door should remain balanced. After replacing the sprocket and chain, test the door to ensure it moves smoothly and evenly. If it feels heavy or uneven, that may indicate a separate issue with the springs or another component.
My rarely used Chamberlain opener sent the token black plastic part to the floor, so I used the rope to shut the door. I called a repairman, sent pics of the piece and he wants $595 to,put a new opener in. Can the opener be fixed (by someone else) just putting a new plastic part (sprocket?) and checking? I should not need a new opener as little as it has been used. 6-7 years old used less than 3 times a month .
This exact problem just happened to me. The garage door was halfway open/closed, and the chain slipped off the sprocket. The chain was very slack, so I loosened the nuts enough to get the chain back on the sprocket, then tightened the nuts up enough tried to adjust the tension. As soo as I activated it, the sprocket broke. It's old enough I should just replace the whole darn thing. But damn, I don't have money just lying around.
*four* turns? Something is way off if it took that. A door should also be balanced close to the bottom and close to the top. You can balance most any spring in the middle, but if the spring is either too weak or too strong, then it will be out of balance at the top and bottom. Springs will lose some strength, that's why most installers set them a little "hot" when they are new, but if they are oil tempered springs, they should maintain their spring rate until they break. The problem with new openers is they tend to lose their settings if power is interrupted because they are all electronics based. They are cheaper to make that way. For those who like buying batteries every few years, there is always the battery backup ones, tho. About the the only good thing I can say is, apparently, that belt one you got should save you some work as belt ones, from what some pros say, don't have gear failures because the belt absorbs a lot of the vibrations instead to passed the stress onto the gears. Of course, if you really want low maintenance, you'll find a V belt version from the 1970's, those basically never break. Just don't try outrunning the door, cuz you'll break before the opener does, lol.

Thank you so much for your reply and assistance. I really appreciate it.

how did you remove the black plastic ontop that the chain travels on
IIRC, that chain spreader is just screwed down. If you look up garage door opener install vids, some of them show that piece being installed.
The only reason I came to this video is because of that black plastic slide.. lol
Where can I buy the kit for repair the gears.? Thanks
