48M578 - Walter 48-M-578 Replacement Bevel Gear and Pinion Set for Big Buff III

Restore Precision with the Walter 48M578 Bevel Gear & Pinion Set

The Walter 48M578 Bevel Gear W/ Pinion is a critical replacement component designed exclusively for the Walter Big Buff III surface finishing tool. As a genuine OEM (Original Equipment Manufacturer) part, this gear set is engineered to the exact specifications required by Walter Surface Technologies to ensure the longevity and performance of their high-end power tools. The set includes both the large bevel gear and the smaller pinion gear, which work in tandem to transfer rotational energy from the motor armature to the spindle at a 90-degree angle.

Over time, the internal gears of heavy-duty finishing tools can succumb to wear and tear, especially in industrial environments where the Big Buff III is used for extended periods on stainless steel, aluminum, and other metals. Symptoms of worn gears often include excessive noise (grinding or rattling sounds from the gear head), vibration, or a loss of torque at the spindle. Replacing the gears with the 48M578 set addresses these issues directly, restoring the smooth, quiet operation that operators expect from Walter tools. Because bevel gears and pinions wear into each other, it is standard engineering practice to replace them as a matched set to prevent premature failure of a new component.

Installation of the 48M578 requires disassembly of the tool's gear housing. It is recommended to clean out old grease and apply fresh, high-quality gear lubricant during the replacement process to ensure optimal heat dissipation and friction reduction. By choosing this authentic Walter part, maintenance professionals ensure that the tooth profile, hardness, and dimensions are perfectly suited for the Big Buff III's high-torque requirements, avoiding the risks associated with ill-fitting aftermarket gears.

Technical Specifications
