Walter Grinder Replacement Bevel Gear and Pinion Set

Get Your Grinder Back in the Fight

There is nothing more frustrating than a trusty angle grinder giving up in the middle of a job. If your Walter grinder has started making a terrible crunching noise, vibrating excessively, or if the disc has stopped spinning while the motor hums, you are likely dealing with stripped gears. The Walter 48M775 Bevel Gear W/Pinion set is the solution to bring your high-performance tool back to life. Instead of scrapping a valuable industrial grinder, a simple mechanical repair can restore it to like-new condition, saving you money and keeping your production schedule on track.

This kit comes with everything you need to rebuild the transmission of your grinder's head: the main bevel gear and the drive pinion. These two parts work together to turn the power from the motor 90 degrees to spin your grinding wheel. They are the heart of the tool's mechanical system. Walter manufactures these replacements with the same rugged durability as the original parts inside the tool when it was new. They are made from hardened steel to resist the punishment of daily grinding, cutting, and blending on steel and stainless steel.

Why replace both? You might be tempted to just replace the one gear that looks broken, but that is a mistake. Gears wear in a unique pattern together. If you mix an old gear with a new one, they won't mesh perfectly. This causes them to "eat" each other, leading to another failure in a very short time. This kit takes the guesswork out of the repair by providing a matched set that is ready to run smoothly right out of the box.

Installation is straightforward for anyone comfortable with tool repair. Simply open the gear head, remove the old grease and broken metal fragments, install the new pinion on the armature shaft and the bevel gear on the spindle, and pack it with fresh grease. The result is a tool that runs quietly, smoothly, and with full torque. Don't settle for generic aftermarket parts that might not fit or last; stick with genuine Walter parts to protect your investment and ensure your safety while working.
