Product Description
At North Shore Commercial Door, we carry a huge selection of garage door opener parts, and the #7575 gear and sprocket kit is one of them. This affordable kit is a direct replacement for the Liftmaster 41C42220A gear and sprocket assembly. This after-market kit is the ideal way to fix up your aging garage door without having to purchase an entirely new unit. The #7575 kit replaces all of the most commonly worn parts in the opener drive system.

Kit #7575 also works with openers from Sears Craftsman, True Value, Master Mechanic and even some Wayne Dalton units. The large gear measures 2.75 inches high and 0.5 inches wide and features a 0.5-inch bore. The worm gear is 1.125 inches OD with 1.25-inch-wide teeth. This kit is far less expensive than an opener replacement, and it's incredibly easy to install with its included instructions.

ANSWER: This part is extremely widely used...easy to install and inexpensive.<br />It comes fully assembled, with a grease packet and even a few extra parts, which I did not need<br />It fit my Craftsman opener perfectly, worked first time.<br />Best idea is to view one of the many YouTube videos before tackling the job.<br />I'm a layman, but that made it easy. Also, find the video that says how to do it but<br />"Don't remove the circuit board". Way faster and no risk way. Mines working like new, and is now 15 years old by Peter T a
ANSWER: I can't comment on the 333C. My part number on the back panel of the GDO is 41A5483-1B, manufactured in 05/04. I can say that the sprocket, shaft and nylon gear came in a single piece as shown. I didn't even need to use the worm gear: the one in the GDO was fine. It's a pretty easy replacement if this part is compatible with your GDO. by Joan A a
