48J738 - Walter 120V Replacement Stator for Big Buff III and Line-Mate III

Technical Overview of the Walter 48J738 Stator

The Walter 48J738 Stator is a critical electromechanical component designed specifically for the maintenance and repair of Walter Surface Technologies' high-performance finishing tools. As the stationary part of the universal motor system, this 120V field coil generates the magnetic field necessary to interact with the armature, driving the rotation of the tool. It is manufactured to precise OEM specifications, ensuring seamless integration with the housing and electrical connections of compatible units.

Constructed with high-grade copper windings and robust insulation materials, this stator is engineered to withstand the thermal and mechanical stresses associated with industrial surface finishing applications. The insulation system is treated to resist abrasion from dust and debris, which is common in grinding and polishing environments. Replacing a compromised stator—often indicated by excessive sparking, overheating, or loss of power—is essential for protecting the armature and extending the service life of the tool.

Compatibility and Installation

This component is the direct replacement for the 120V versions of the Big Buff III (Model 6265) and Line-Mate III (Model 6268). Technicians should verify the tool's model number and voltage rating before installation. Proper seating of the stator within the motor housing and correct routing of the lead wires are required to ensure safety and performance.
