48J727 - Walter Replacement Output Gear for Big-Buff III and Line-Mate III

Precision Replacement Output Gear for Walter Finishing Tools

The Walter 48J727 Output Gear is a critical internal component designed specifically for the transmission systems of Walter Surface Technologies' high-performance finishing tools. Engineered to exact OEM specifications, this gear serves as the primary link in the torque reduction and power delivery chain within the tool head. It is manufactured from high-grade, hardened steel to withstand the significant mechanical stresses and thermal loads generated during continuous industrial brushing, sanding, and polishing operations.

When a power tool's transmission begins to fail, symptoms often include excessive noise, vibration, or a loss of rotational torque at the spindle. The output gear is frequently the component subjected to the highest wear due to its engagement with the armature pinion. Replacing a worn gear with this genuine Walter 48J727 unit restores the mechanical integrity of the tool, ensuring that the motor's power is efficiently transferred to the abrasive media without slippage or binding. This part is precision-cut to mesh perfectly with the mating gears in the Big-Buff III and Line-Mate III assemblies, minimizing backlash and ensuring smooth operation.

Maintenance professionals and tool repair technicians rely on genuine Walter parts to maintain the safety and longevity of their equipment. Using non-OEM gears can lead to poor fitment, accelerated wear of the armature shaft, and potential catastrophic failure of the gear housing. This output gear is heat-treated to resist tooth pitting and fatigue, extending the service interval of your valuable surface finishing equipment. It is an essential spare part for facilities maintaining a fleet of Walter finishing tools.

Technical Compatibility

This gear is specifically engineered for the following models:

• Big-Buff III: Model 30-A 265


• Line-Mate III: Model 30-A 268

Proper installation requires disassembly of the tool head gear case. It is recommended to inspect the grease and seals during replacement to ensure a comprehensive repair.
