- Here is a short video on the process to replace a bench/pedestal grinding wheel. As with all power tools, step 1 is making sure it is unplugged!!

Here are some safety tips:
always check new wheels for cracks by balancing the wheel on a finger in the bore, then tap wheel with a hammer shaft, it should ring, if it sounds dull, the wheel is cracked.
Then when you have fitted the new wheel, (with new paper gaskets) check for concentricity by turning by hand, any slight wobble can be corrected by manipulating whilst tightening, DON'T overtighten!.
Always break the old wheel up and dispose of to prevent it being used again.
buy the way, the left wheel is always a left hand thread, the right wheel is right hand. That is to stop the wheel coming off when using. Hope this helps keeping you, and any bystanders/students safe.
What may have taken me 10 minutes or so, literally took me under two minutes because of this video… Thank you very much!
Haha...killin' me.
Nothing drives me crazier than when I run into a job, and do not have the tool. I was doing this today, and none of my sockets were big enough. EVERY time that happens, I find a work around to get the job done, and then within a day, buy the right toolk so I never have to work around it again.
At 53, after a lifetime of this policy, I RARELY run into a situation where I do not have the tool. But today I did, so I worked around it with a crescent wrench. Which lead me here...just trying to find out size that nut is.
...and you whip out a crescent wrench. As I began...killin' me!
Thanks! I’m swapping my grinding wheel for a wire wheel and this really helped.
Antigone is a real one, got me my current job!
Thank you for this. The flange nuts were stuck on my wheel, I'd never changed one before, and the manual for my grinder didn't explain how to remove them. And yeah, it's clear how to do that after the fact, but not if you're standing in your garage trying to make sure you're not acting rashly.
You forgot to do the ring test before installing the new wheel :)
Correct use of Adjustable wrench. The movable jaw toward the direction of rotation to minimize force on adjustable jaw.
Never did a ring test. People do not do that like this. Very dangerous.
I'll bet these two idiots can't even sharpen a drill, glad i read your comment never done a ring test what a bunch of tools, no pun intended 😉 😜 😀 😆
Thanks for the short & sweet video on changing out a grinding wheel. All pretty straight forward. I just installed a new Norton Aluminum Oxide wheel on my 6” Delta grinder. The Norton wheels come with variable plastic bushings to ensure snug fit on the arbor. My first attempt wasn’t snug enough yielding massive out of balance. On careful inspection, I needed one more bushing. Once snug, all worked out well.
Ps - what in the world was being ground that caused that damage to your wheel?
What about showing checking for balancing, balancing and trueing the wheel? Most wheels will have problems with this when added to a grinder and not addressing these is a safety risk, sometimes a major one depending on how far off it is.
This is a small unit and did not need that. If there is a longer shaft unit, with a larger wheel, or different weight wheels on each end, it would need to be done. Not this one.
I respectfully disagree. New wheels should always be checked for true no matter the size. I have a grinder that same size (i can tell by its size relative to your hand size) and have worked with a number of grinders that size and smaller and they can explode if true is out too much and not dressed. I've seen wheels that size have nearly 1/8 in side to side wobble and nearly the same in lack of roundness that were brand new. Always check for true ... better to be safe than injured. I've also seen new wheels checked for the ping test and not pass. Safety necessitates always checking a wheel. Because this is essentially an instructional video, it would be wise to include such info as recommendations. Good info on your cad instructions though.
What kind of mask do you recommend I should wear for changing a grinding wheel 😂
The one you was born with 🤣🤣🤣🤣🤣🤣🤣🤣🙉
Would the right side nut come off normally being counter clockwise?
The nuts on each end turn opposite to each other, like faucet handles.
Mine did
Why didn't you do mandatory 2 point safety and trueing checks?
Thanks for the informational video! I want to get a bench grinder but cant find one with a wire wheel so i am resorting to just changing them out
Your welcome. Agreed. We all have to do it this way.

Thanks.
Wow... I've never had a wheel just pop on and not wobble. Lol. Probably should've added in how to mount the wheel so it doesn't have any wobble.
one washer each side would promise a more even spread of the pressure when tighten .....
Righty tighty....? Really? It's clockwise/counterclockwise. For the digital generation, you pull out an old clock to teach them what it means. Geesh!
Anything you can do...
It’s called a reverse thread
The last one was.
Whett your paper!!

Pretty terrible instruction to “just hold the wheel and loosen the nut”. First of all that won’t be possible if it is tight, and it’s not safe to try to grip it anyways. The threads are opposite on each spindle, just use two wrenches, one on each spindle.
You can't loosen the nut on this model if you don't hold the wheel. Some have a break. This particular grinder did not. Yes, you can hold both ends, but I chose not to do it with this small unit.
@@antigonesharris why not just use two wrenches like I described? I have a Jet also and it doesn’t have a brake. It’s much safer and easier. I don’t care how you want to maintain your machine but you are recommending to everyone the way to do it and it’s plain wrong and dangerous.
@@antigonesharris I have owned a revenue producing machine shop since 1980 and worked in the machine tool repair business even before that. - (We are industrial electrical/millwright contractors) The next pedestal or bench grinder I see with a brake will be the first one. The more you talk the more clueless you prove you are.
No. if you use a wrench on each spindle you can dangerously over tighten the other wheel. Your wheels should never be that tight.
@@onesixfiveyou guys are incorrect. If used ONLY two wrenches to tighten, one on each side, you would be pushing away from your body with both wrenches as the left wheel is reverse threaded and the right is regular. You would literally be spinning the whole spindle and both wheels. You need two wrenches and a block of wood to stop the wheel.

Really? Masks??? LMAO.
I don't think she knows a lot about what's she's doing she didn't check allot of things
Well she is a woman for f♤♡k sake 🙄
2 minutes in and I'm disappointed with this video. Two people to change a wheel???? Fail.
And one's a woman 🤣🤣🤣🤣🤣🤣🤣
Take the damn mask off people
Terrible. She should have done her research before putting this out for world to see. Bad terminology, not even knowing how to use tools or any crucial steps of the process. My 8 year old can do what she did. I really hope she’s not a teacher. Sorry, but for something so common I don’t see how she missed so many marks. FFS
