{"product_id":"dewalt-n112877-ring-gear","title":"Dewalt n112877 Ring Gear","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe DEWALT n112877 is a ring gear replacement part designed for use in DEWALT power tools. The ring gear is a core drivetrain component that meshes with planetary gears inside a gearbox assembly to transfer torque from the motor to the output spindle or chuck. When a ring gear wears, cracks, or strips, the tool loses drive or produces grinding noise under load. Replacing it restores full mechanical function without requiring a complete gearbox or tool replacement. This part is installed by power tool repair technicians and experienced service professionals.\u003c\/p\u003e\u003cp\u003eThe n112877 ring gear is suited for service and repair applications on compatible DEWALT power tools. It is typically encountered during gearbox rebuilds where the planetary gear train has experienced wear or impact damage. This part is intended for professional repair use and is not a general consumable. Consult the applicable DEWALT service documentation to confirm fitment before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM-style ring gear engineered to match original drivetrain geometry\u003c\/li\u003e\n\u003cli\u003eRestores torque transfer when the planetary gear train is worn or damaged\u003c\/li\u003e\n\u003cli\u003eDirect replacement format simplifies gearbox reassembly\u003c\/li\u003e\n\u003cli\u003eDesigned for professional-grade DEWALT power tool repair applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement ring gear for compatible DEWALT power tools.
