Changing a Bench Grinder’s Wheel

Category: Bench grinders

First things first, before changing a bench grinder wheel, you need to wear safety glasses. You should also not exceed the torque level as recommended when tightening the bolt and securing the wheel. We say this because doing such can lead to the wheel coming off while you are using it.

You should also make sure that the replacement wheel has the right size and speed rating for your speed grinder. You will need the following tools when changing your bench grinder wheel:

  • A screwdriver
  • Safety gloves
  • Lubricating oil
  • Adjustable wrench
  • Replacement wheel and
  • Safety glasses.

So, let us dive into the article.

  1. First step – Your safety: Make sure the bench grinder is not plugged to the main source. The backup power source should be switched off just in case it is connected to such. If it is possible to remove the power lead, you should go ahead and do so, so as to prevent any obstruction.
  2. Second step – Know your tool: Doesn’t really matter if you are already familiar with the application of the bench grinder, it is still vital that you do a quick study of the tool that you will need to execute the task. Inspect your bench grinder to know how it works and what parts need to be replaced. You should also check the guide because this will show you the full details on how you can replace and detach the wheel.
  3. Third step: Many bench grinders come with a safety guard that needs to be taken off so that you can quickly remove the wheel, and to do this, you’d need screws that attach it to the main body of the machine. After doing that, you should remove them gently with a screwdriver, then you take off the safety guard completely instead of just twisting it out of the way.
  4. Fourth step – Remove obstructions: Find the drive shaft of the bench grinder and unscrew the nut and washer that anchor the wheel with a wrench. Put them aside and keep them where you won’t lose them. If the wheel is stiff, apply some amount of oil on the joint of the shaft and nut. After you do that, gently remove the wheel, but be sure to wear some protective gloves as you do so.
  5. Fifth step – Attaching the new wheel: Put the new wheel just the same way they were formerly positioned. You will need to ensure that you put the wheel the right way, and this depends on the type of wheel you’ll be mounting. After this, you slide the new one to the farthest point it can reach and you push the washer and nut. With a wrench, tighten the nut back into place, but do not do this with too much force.
  6. Sixth step – Testing: You can test the new wheel by turning on the machine and standing back, watching the wheel turn. Listen to anything unusual. If anything seems out of place, switch the machine off before correcting it.
