Pedestal grinder maintenance - Fitting a new grinding wheel

Video

The following must be done before fitting a new wheel on a pedestal grinding machine:

Select the correct wheel for specific operation (see wheel selection) Ensure the wheel was correctly (transported and stored) Ensure correct wheel size for machine Make sure the machine does not exceed maximum allowable speed of the wheel Ensure there is blotting paper on both sides of the wheel Make sure flanges is at least on third the diameter of the grinding wheel. Do ring test on new wheel to ensure it is not cracked

Here are the steps:

Safety first - make sure you unplug the pedestal grinder before you do anything else. Remove the safety guards - this may take a little while if you have a lot of guards to remove. You should have the tongue guard, eye guard and the wheel guard to remove. Make sure to keep your screws organized and in a safe place so they do not get lost. Next, remove the tool rest. After that, use a wrench to loosen the nut or bolt holding the wheel. You may need to hold the other wheel when you do this to keep the wheels from turning. Once you have that done, take off the washer and pull the wheel off. Inspect the shaft for corrosion and wear Gently slide wheel onto the shaft, do not force it onto the shaft. Tightened nut only by hand and not with wrench as it will tightened by it self when starting the machine. Replace guards Perform a truing operation to ensure the wheel is running centric with out any vibration. Readjust work rest to not more than 3 mm from the wheel. Complete the machine maintenance register on work done.
