Troubleshooting & FAQ

How can I confirm this guard will fit my specific grinder model?

This guard is designed for Universal Tool grinders that use a 4" Type 27 grinding wheel. The best way to confirm fitment is to compare the shape, mounting points, and dimensions of our product (shown in the images and technical specs) with your original guard.

Is this guard as durable as the original OEM part?

Yes, this is an aftermarket part built to meet or exceed OEM specifications. It is constructed from durable materials suitable for industrial use, ensuring reliable performance and longevity.

What are the signs that a grinding guard needs to be replaced?

Inspect your guard regularly for signs of wear, cracks, bending, or other damage. If the guard is loose, deformed, or has been impacted, it should be replaced immediately to ensure operator safety.

Can I use a different size or type of grinding wheel with this guard?

No, this guard is specifically designed for 4-inch Type 27 grinding wheels. Using other sizes or types can be extremely dangerous and may result in guard failure and serious injury.

Why is the part number 985052 also listed for a Volvo car part?

Part numbers can sometimes be reused by different manufacturers for completely unrelated components. This grinding guard is for Universal Tool equipment and is not related to the Volvo flange screw that shares the same number.
