OVERVIEW

Restore Precision Control with the Walter Speed Shifter Assembly

The Walter 48J712 Speed Shifter Assembly is a critical replacement component designed specifically for Walter Surface Technologies' high-performance finishing tools. Engineered to meet the exact specifications of the Line-Mate III (Model 30-A 268) and the Big Buff III (Model 30-A 269), this assembly is essential for the proper operation of the tool's variable speed transmission system. When your industrial finishing tool loses its ability to shift smoothly between speed settings, or if the speed control mechanism becomes loose or unresponsive, this OEM part provides the factory-correct solution.

Industrial surface finishing requires precise RPM management to achieve specific results, from aggressive material removal to mirror-finish polishing. The Speed Shifter Assembly governs the mechanical engagement of the tool's gearing, allowing the operator to select the optimal speed for the abrasive being used. A worn or damaged shifter can lead to stuck gears, inability to adjust speed, or potential damage to the tool's internal transmission. By installing this genuine Walter part, you ensure that your equipment continues to deliver the torque and speed consistency required for professional metalworking.

This assembly is constructed from high-durability materials to withstand the vibration and thermal stresses common in heavy-duty industrial environments. It is a direct-fit component, meaning no modifications are required for installation, ensuring a seamless repair process that minimizes downtime. Maintenance professionals and tool repair technicians rely on genuine Walter parts to extend the lifecycle of these premium power tools.

Key Technical Benefits

  • Exact Fitment: Designed exclusively for Walter Line-Mate III and Big Buff III chassis.

FAQ

The 48J712 Speed Shifter Assembly is compatible with the Walter Line-Mate III (30-A 268) and the Big Buff III (30-A 269).

Yes, this is a genuine OEM replacement part manufactured by Walter Surface Technologies.

Symptoms include the tool being stuck in one speed, the speed selector switch feeling loose or disconnected, or an inability to engage specific RPM ranges.

This is the shifter assembly mechanism itself. It typically engages with the gears but does not usually include the main transmission gears unless specified in the diagram.

Installation requires partial disassembly of the tool's gear head housing. It is recommended to follow the schematic for the Line-Mate III or consult a qualified tool repair technician.

No, this part is specifically listed for the Line-Mate III series. Older models may use different internal components.

Different abrasives require different speeds; for example, polishing requires lower RPMs to prevent burning, while grinding requires higher RPMs for material removal.

The part number is often written as 48-J-712 or 48J712.
