Direct Replacment Kit # 7575 Gear and Sprocket Kit
This item is discontinued. Please view this replacement item:
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 041C4220A 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.
