Review: Top quality and pricey - This OEM kit was quite a bit more expensive than the cheap aftermarket replacements, but worth it. I made sure to re-balance the garage door first, as I believe that contributed to the original gear stripping out. It worked well for more than 20 years! Installation was pretty easy, helped by a couple of videos on YouTube.
Review: Worked quite well. Easy install. - As you can see in the picture, the old gear was completely stripped of it's teeth. I was going to make a gear, but that's time consuming and a lot of work. When I found the gear AND it's assembly online for only $20 I jumped at it. I did not read the included instructions because I'd already watched a few youtube videos on how to fix it. The packaging left something to be desired, as it was a plastic bag of parts in a puffy envelope. That's desertcart's choice. The gears could have been damaged or the shaft could have been bent by whatever machine gouged the outer envelope. I'd suggest that they use a box inside the puffy. Installation was simple. Remove the outer case (8 screws) and then remove the chain. Take out 3 screws to remove the assembly and then reverse the process to put it all back together again. All in all, it took me about an hour and a half, and that included looking for wrenches, moving things out of the way and checking the garage door for proper operation. The product looks to be good quality in good shape. Everything fit exactly as desired.

## Questions & Answers

**Q: the chain gear sprocket broke  how do i change the drive sprocket**
A: You have to replace part number 41C4220A. It requires taking the motor unit down and removing the 3 small bolts and the small nylon gear from the bottom of the drive shaft and replacing the complete shaft with the gears as a unit.

**Q: need gear and sprocket kit for liftmaster 41a5021-1h-315. do you have it or what the part number is?**
A: Sorry, I do not have the same model as your. I took a chance because the description notes said it worked with most lift master, Chamberlain, and craftsman chain drive openers. Seemed pretty universal.

**Q: I need a 41AC050-1 would this fit?**
A: I am not familiar with the # you have posted. I would order this kit and compare all parts before trying to install. It can be easily returned if not damaged. If it fits be sure to use copious amount of the lube on all nylon gears and bushings.

**Q: I'm looking for the slide gear or travel gear for a Liftmaster Professional 1/3H ?**
A: Not sure what part your looking for but maybe one of these https://www.amazon.com/T-Rail-Trolley-Assembly-Genuine-Parts/dp/B00U2PT5MW/ref=sr_1_1?ie=UTF8&qid=1523039636&sr=8-1&keywords=041a3489

### ⭐⭐⭐⭐⭐ Easy to Install Replacement Gear Assembly (I’ve included some installation tips)
*by R***W on April 19, 2016*

This “Liftmaster Gear Kit” had everything I needed (and then some) to fix my LiftMaster Professional Model 3265 garage door opener. Both the washer above and below the top sprocket gear that rotates the chain had become worn-out and broke, so the gear would wobble and the chain would come off. Replacing the entire “top-hat assembly” was not too difficult and it worked perfectly. NOTE: To thread the Top-Cap/Top-Hat holes: Place the Top-Hat into a vise. Take one of the old 5/16th screws (you removed from the old top-hat) and lubricate the threads with some of the included grease (WD40 or 3-in-1 oil would probably also work). The screws have a hex-head so take a handheld screwdriver with removable tip and remove the tip and then place the screwdriver directly on the hex-head screw and manually turn it (force it) into the unthreaded hole on the top-hat. Back out the screw and repeat. It was fairly easy to do and didn’t take me long. NOTE: Adjust the gear timing: Before re-installing the chain, make sure you first adjust the gear timing. To do this, make sure your garage door is off the trolley, and place your garage door in the fully down position. Then plug-in your opener and push the button (with the chain still off). If the top gear turns counter-clockwise, then push the opener button again, until the gear turns clockwise and stops spinning on its own (a complete down cycle). Then, unplug your garage door opener and turn the chain by hand (with gloves) to re-attach the trolley. Next, attach the chain to the opener top sprocket gear, and adjust to the proper tension level. Plug in your opener and test it.
