Dewalt 5140078-45 Extension Spring

Product Description

The DEWALT 5140078-45 is an OEM extension spring designed as a replacement component for DEWALT power tools. Extension springs store mechanical energy under tension, returning moving assemblies to their resting position when force is released. This type of spring is a common wear component in power tool mechanisms and is replaced by service technicians and repair shops performing tool maintenance or restoring function after spring fatigue or breakage.

This extension spring is sourced directly from DEWALT as a genuine OEM replacement part. It is intended for use in DEWALT power tool assemblies where the original spring has worn out, lost tension, or failed. Refer to the specific tool model's parts diagram to confirm correct fitment before installation.

Use the appropriate hand tools and refer to the manufacturer's service documentation to identify correct spring placement and orientation.
