Creality Extrusion Kit – OEM Replacement – K1 / K1C / K1 Max / K1 SE / Ender-3 V3 – 4001020076 The Creality Extrusion Kit (4001020076) is a genuine OEM replacement extrusion assembly designed to restore reliable filament feeding and extrusion performance on compatible Creality 3D printers. This assembly contains the mechanical extrusion components responsible for gripping, feeding, and retracting filament as it moves toward the hotend. It is an ideal replacement for a worn, damaged, or malfunctioning original extruder. Important: This extrusion kit does NOT include the extruder motor. Product Function The extrusion kit works with the printer's extruder motor to grip and precisely control filament movement during printing. Proper operation helps provide: Smooth and consistent filament feeding Accurate filament retraction Reliable extrusion during high-speed printing Reduced filament slipping and grinding Consistent material flow to the hotend Reliable filament loading and unloading Improved extrusion consistency and print quality Key Features Genuine Creality OEM replacement part Creality Part Number: 4001020076 Complete mechanical extrusion kit Extruder motor not included Durable black housing PA6 reinforced with 20% glass fiber construction Designed for precise filament feeding and retraction Suitable for high-speed 3D printing Direct replacement for the original extrusion assembly Ideal for printer maintenance and repair Helps restore original extrusion performance Specifications Brand: CrealityProduct Type: Extrusion Kit / Extruder AssemblyManufacturer Part Number: 4001020076Official Description: Extrusion Kit_Nearly_PA6+20%GF_BlackHousing Material: PA6 + 20% Glass FiberColor: BlackFunction: Filament Feeding & RetractionInstallation Location: Toolhead / Extruder AssemblyMotor Included: NoApplication: FDM/FFF 3D PrintingCondition: New Replacement Part Compatible Printers Creality SKU 4001020076 is used with compatible models including: Creality K1 Creality K1C Creality K1 Max Creality K1 SE Creality Ender-3 V3 Always verify your printer model and original part number before ordering. When Should the Extrusion Kit Be Replaced? Replacement may be necessary if your printer experiences: Filament slipping Extruder clicking or skipping Filament grinding Inconsistent extrusion Under-extrusion Difficulty loading or unloading filament Poor filament grip Worn or damaged extrusion gears Physical damage to the extruder housing Before replacing the extruder, also inspect the nozzle, hotend, filament path, and PTFE components, as clogs or obstructions can produce similar symptoms. Package Includes 1 × Creality Extrusion Kit – 4001020076 Extruder motor is NOT included. Important Notes This product is the mechanical extrusion kit only and should not be confused with Creality extrusion assemblies that include the extruder motor.
