Walter 48-H-352 Replacement Motor Housing for Big Buff III & Line-Mate III

Get Your Walter Tool Back in Action

We know how it happens—you're in the middle of a heavy polishing job, the tool takes a tumble from the bench, or gets knocked around in the truck, and suddenly you've got a cracked case. The Walter 48-H-352 Motor Housing is the exact replacement part you need to fix your Big Buff III or Line-Mate III and get back to work. Don't try to patch up a broken power tool with tape or glue; a compromised housing isn't just uncomfortable to hold, it's a safety risk that exposes the motor to dust and leaves you vulnerable to electrical issues.

This is the genuine orange body shell from Walter Surface Technologies. It fits your machine perfectly because it was made on the same molds as the original. Swapping out the housing is a straightforward repair that can save you the cost of buying a brand-new tool. Once installed, your Line-Mate or Big Buff will feel solid in your hands again, with no loose wobbles or rattling parts. The tough plastic construction is built to take the heat and the knocks of daily shop life.

Why buy OEM? Because fit matters. Cheap knock-offs often don't line up right with the screw holes or the brush caps, turning a 10-minute fix into an hour of frustration. With the 48-H-352, you simply disassemble your tool, transfer the guts into the new shell, and screw it back together. It restores the proper airflow to keep your motor cool and protects the expensive internals from metal dust and grinding grit. Keep your high-end finishing tools running like new with the right parts.
