The following procedure will vary on all models. To inspect for a possible seized bearing, remove the grinding wheel cover and handle. Remove the outer flange, grinder wheel and inner flange. Remove the screws securing the gear box assembly to the grinder and then separate the gear box assembly from the grinder. Remove the lower cover.
Now reinstall the bolts and lightly snug them down. Now torque both bolts to 35 ft lbs of torque. Now retry. If it still grinds you'll likely need another starter, but it should be okay. What causes it to grind is the starter moved and it moved due to the bolts not being tight enough. The starter cant move when in use, if it does the grinding ...
