Hi Jimmy,
Thank you for your question. If your wheel is not turning, there are some parts that you will need to check to see which one is causing the issue. You will need to check the the gears, the flange, the spindle, and the coupler. We have included a link that you may reference on how to check these parts, https://www.ereplacementparts.com/repair-center/power-tool/grinder/motor-spins-but-grinding-wheel-doesn't/.
