Walter Replacement Bevel Gear and Pinion Set for Angle Grinders

Get Your Grinder Back in the Fight

There is nothing worse than being in the middle of a heavy fabrication job and hearing that tell-tale crunching sound coming from your angle grinder. When your grinder starts slipping, making grinding noises, or the wheel simply stops spinning while the motor screams, it’s often a sign that your gears are stripped or worn out. The Walter 48M493 Bevel Gear and Pinion set is exactly what you need to fix the problem and get back to work. Don't throw away a high-quality Walter tool just because of a worn mechanical part; rebuild it with this kit and it will run like new.

This kit comes with everything you need to overhaul the transmission of your grinder: the large bevel gear and the small pinion gear. It is crucial to swap them both out at the same time. Think of it like changing the chain and sprockets on a bike—they wear together, so they need to be replaced together to run smoothly. These are genuine Walter parts, meaning they are built tough to handle the abuse of a welding shop. They are made from hardened steel to resist stripping, even when you are leaning into the tool for heavy stock removal or beveling pipe.

Installing the 48M493 is a straightforward repair that can save you the cost of a brand-new tool. Once installed, you will notice an immediate difference. The vibration will decrease, the noise will drop to a normal hum, and most importantly, the torque will be back. You'll be able to grind down welds and cut through steel without the wheel stalling out. Keep your shop running efficiently and extend the life of your investment with factory-original replacement parts. Whether you are a professional welder, a fabricator, or a shop foreman, having the right repair parts on hand means less downtime and more arc time.
