Dewalt 5140074-79 Spring Pin

Product Description

The DEWALT 5140074-79 is a spring pin used as an internal retention or alignment component in DEWALT power tools. Spring pins are hardened, slotted fasteners that compress during installation and expand to hold position within a bored hole, securing moving or stationary subassemblies inside the tool housing. This part is sourced as a genuine DEWALT replacement component and is installed during service or repair by technicians working on DEWALT tool platforms. It is a small but load-bearing component whose failure can affect tool function or safety.

This spring pin is applicable to DEWALT power tool repair and maintenance scenarios where the original pin has sheared, deformed, or worn beyond serviceability. It is typically encountered during drivetrain, chuck, or housing disassembly on applicable DEWALT models. Installation requires the tool to be fully de-energized and disassembled to the appropriate service depth before the pin is driven or pressed into place.

Key Features

• Genuine DEWALT replacement spring pin for internal tool assembly
• Slotted roll-pin design compresses on insertion for secure retention in bored holes
• Hardened construction resists shear and deformation under operational load
• Direct OEM replacement eliminates fitment guesswork during service

Compatibility

Designed as an OEM-style replacement spring pin for applicable DEWALT power tools. Consult the specific tool service manual or parts diagram to confirm this pin fits the target assembly before ordering.

Installation Notes

Installation is performed by qualified service technicians familiar with DEWALT power tool disassembly procedures. Disconnect and de-energize the tool completely before beginning any internal service work. A roll-pin punch and hammer or an arbor press is typically used to drive or press the pin flush or to the specified depth within the bore. Follow the applicable tool service manual for correct orientation and seating depth.
