Dewalt 5140071-54 Field and Armature Assembly

Product Description

The DEWALT 5140071-54 is a field and armature assembly used in DEWALT power tools. The field coil and armature work together as the core electromagnetic components of a brushed motor, converting electrical energy into mechanical rotation. This assembly is a direct replacement part intended for use during motor repair or rebuild service. Technicians and service professionals install this part when diagnosing motor failure, excessive brush wear, or loss of power output in compatible DEWALT tools.

This assembly is suited to service environments where DEWALT power tools are repaired at the component level rather than replaced as a unit. It is appropriate for use in authorized service centers or by qualified technicians with experience in brushed motor repair. The part restores motor function by replacing worn or failed field windings and armature components as a matched set.

Key Features

• Combined field and armature assembly for efficient motor rebuild
• Designed as a matched set to ensure proper electromagnetic pairing
• OEM DEWALT replacement part for consistent fit and function
• Supports brushed motor repair without full tool replacement

Compatibility

Designed as an OEM-style replacement field and armature assembly for compatible DEWALT brushed motor power tools. Consult the DEWALT parts reference or service documentation to confirm fitment for a specific tool model before installation.

Installation Notes

Installation should be performed by a qualified power tool service technician familiar with brushed motor disassembly and reassembly. Disconnect and de-energize the tool completely before beginning any internal service work. Proper motor housing alignment and brush seating should be verified after installation. Follow all applicable manufacturer service procedures during reassembly.
