Walter Replacement Gear Box for Big Buff III and Line-Mate III

Keep Your Walter Tools Running Like New

If your Walter Big Buff III or Line-Mate III has started grinding, slipping, or getting hot at the head, it might be time to swap out the transmission. The Walter 48H470 Gear Box is the genuine replacement part you need to get your favorite finishing tool back in the fight. We know that in a busy shop, your tools take a beating. The gear box is what takes all that power from the motor and puts it into the wheel or drum. When it starts to go, you lose the torque you need to pull a consistent grain on stainless or buff out a scratch.

Don't let a worn-out gear set slow down your production. This 48H470 assembly is the real deal—straight from Walter. It’s built tough with a heavy-duty housing and precision gears that fit perfectly into your existing tool body. No modifying, no guessing, and no "making it work." It drops right in so you can get back to work fast. A fresh gear box cuts down on the vibration that tires out your hands and arms, and it brings back the smooth, quiet operation the tool had when you first bought it.

Why buy a whole new tool when the motor is still strong? Swapping the gear box is a smart fix that saves you money. This assembly handles the high torque required for linear finishing and buffing without skipping a beat. It’s designed to handle the heat and stress of daily industrial use. Whether you are polishing railings, cleaning welds, or blending surfaces, you need your tool to spin true and steady.

Installation is straightforward for anyone comfortable with tool repair. Once installed, you'll notice the difference immediately—no more rattling, just smooth power. Keep your shop running efficiently and keep your Walter tools in top shape with this OEM replacement part. It’s the best way to ensure your finishes stay consistent and your tools last for years to come.
