At North Shore Commercial Door, we carry a huge selection of replacement garage door opener parts, and the #7576 gear kit is one of them. This affordable kit is a direct replacement for the Liftmaster 41A2817 gear 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 #7576 kit replaces all of the most commonly worn parts in the chain drive opener drive system.
Kit #7576 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.
