Dewalt 1343890 Replacement Gear

Product Description

The DEWALT 1343890 is a replacement gear designed for use in DEWALT power tools. Gears are internal drive components that transfer torque within a tool's gearbox, translating motor output into the rotational force needed at the chuck or blade. This part is installed by trained service technicians during routine maintenance or following mechanical failure. Replacing a worn or damaged gear restores proper tool function and extends service life without requiring a full tool replacement.

This gear is suited for repair applications where the original gear has worn teeth, visible damage, or is causing abnormal noise or vibration during tool operation. It is intended for installation in the specific DEWALT tool model or models that use this part number. Repair technicians working in authorized service centers or independent shops will find this a direct-fit internal component.
