You should be able to hold the grinding wheel with a pair of leather gloves on your hands and lossen the bolt. Look very carefully at the threads to make sure you are trying to lossen and not tighten. Some are left handed threads on bench grinders.

Usually a new wire wheel comes with different size bushing just for the problem you are describing. Either that or take it back and get one specifically for your tool.

without having the model number I can only go from experience on other grinders. First you would have to unplug tool and remove outer guard housing to expose the hex nut, one side of the tool would have a left hand thread and the other standard so you would need to hold both the hex nuts at the same tme and try both ways, when you get one off put a GOOD pair of pliers or similar device on the shaft and remove the other wheel

You may need shims and bushings to fit some wheels. get a good tight fit.

SOURCE: How do you tighten the nuts when changing the

Clamp the shaft behind one wheel with 'Channelock' or 'Visegrip' pliers, then tighten both nuts. Check the new wheels for 'off-center' running by spinning them with your hand. They may fit the shaft tight enough that there is no centering adjustment--use a 'wheel dresser' (either a stone type or a multi-wheel type) to true up the wheel so that there is no radial wobble. Hope this helps!
