Dewalt 163930 Feed Piston Spring

Product Description

The DEWALT 163930 is a feed piston spring designed as a replacement internal component for DEWALT power tools. This spring maintains consistent tension on the feed piston assembly, ensuring reliable cycling and proper tool operation during use. It is a precision-formed small-part component typically replaced during a service rebuild when the original spring shows signs of fatigue, deformation, or failure. Licensed technicians and authorized service centers are the primary installers of this type of internal drive component.

This feed piston spring is intended for use in DEWALT power tool applications where the original spring requires replacement due to wear or damage. It is suited for service and repair scenarios, typically in a workshop or field-service environment. This part is a direct OEM-style replacement that restores proper piston feed function when the tool begins cycling inconsistently or fails to feed correctly.

Installation Notes

Installation of internal power tool components should be performed by a qualified technician or authorized service center.
