L picked this angle grinder about 2 years ago and about 5 months ago it started to slip at the gear head, lets take it apart and see if we can fix it.

Allways leave the guard on correctly.
Love your channel!!! I like nononsenseknowhow also. Your videos have that, "Just hanging out in a buddy's garage tinkering with stuff" kinda vibe. Very relaxed, and low key. My favorite part is when you ask us what we think!!! Priceless!!!
I've had to fix my AEG angle grinder 3 times! One time the motor brushes wore out and I had to modify some to fit. Another time a motor bearing collapsed. The other thing was the switch, it was a 2 pole switch but one pole failed so I bypassed it and use it on one pole. I use the diamond discs which don't shatter.
I had one of these kick on me. It had cutting disk and no guard it really was a hand grinder.
I wish I had a teacher like Mustie in HIGH School!
I would have ground down the welds and separated it then reweld it.
Not using the guard with a cut-off wheel, i laid my pointer finger wide open at the knuckle when the grinder kicked back and did a 360 flip in the air before landing on my knuckle. I was told to ggo get stitches but I chose to use butterfly bandages instead. Healed good with a scare line and hurts when weather is cold. But otherwise everything is all good😄ðŸ‘
The guard is literally in the way all the time.
Should be using faceshield and gloves anyway.
I have a curtain set up to keep it off of everything and ambient dust collection too.
Loctite….?
OK. 😐
And why do people insist on insane amounts of oil, WD40, loctite, CARB CLEANER, every time.
I take it off so I can use a much bigger wheel. but you know, saftey 3rd.
That's a perfect situation for a tig torch and no filler rod
When you have a different disc thickness your supposed to flip the lock nut to have more threads on it
That's why they have two hand holds as well as a discharge shield to keep folks safe but if things are seriously going to go wrong that should isnt going to be much help in preventing and the shields intent was grinder stones shattering at speed or breakdown
Dont know mustie1 I have one and would have opened mine up to see if mine was like the one you have there the same model too
Great repair video
Obligatory comment for the algorithm
I'm watching in June of 2021and there's your beautiful girl at the end. R.I.P. Lily.
I think your doggie likes "5 guys"…Excellent Repair Job!!! THANKS FOR MAKING the video!
Two years ago.
How's the yellow/red grinder holding up?
I have one just like that bought it new about 17 years ago still works great
Explanation of how important a guard is…..removes and installs disk with unit plugged in.
Use a shop vac on the bottom side to draw the locktite down into the shaft area
Why not just put a tag on it instead of making it look like crap with red paint.
I remember doing my abrasive wheel course many years ago and they showed a video of a cutting disk exploding with and without the guard on. The jell dummy didn't look very well after the non guard disk broke. Angle grinders are more dangerous when you are comfortable using them!
Mmmmmmm, Five Guys.
Needs more cowbell
Were you attaching the disc with the tool plugged in?
I tend to gravitate to the lower end grinders, being that I'm a 250 lbs. gorilla and I like to melt their insides in fairly short order. When in doubt, let the smoke out…
I would look at the scrap yard for a grinder like the one you repaired, and repair yours with the parts from that. It's not common for that part to fail.
Hey mustie, locktite makes a wicking thread locker, I believe it’s green. Useful for many applications.
Bought myself an off brand grinder with some Christmas money early in the year. Put it a tool bag and on a shelf. Later when moving the shelves, I commented to my wife to take the bag off so as not to hurt the new grinder… of course, she thought that was nonsense, and the bag crashes to the garage floor. Had the guard not been installed, the disc and even the arbor may have been badly damaged. The guard was relatively easy to fix.
yes i really enjoy fixing things
Thought I was watching an AvE video for a second there.
A lot better than the carb for a Stihl 015 that I recently rebuilt. The cobbler who owned it before me glued every gasket and diaphragm on the carb. They had also epoxied every bolt on the saw. I had to drill lots of bolt heads off.
Loctite = I BET NO
locktite ? really ?
nice lab .
Thanks now I know how to fix my dewalt 4.5 grinder other than throughing them in the trash when it starts slipping. I have throwed away 5 or 5 because of that.
The person in charge of the complaint department is Helen Wait. If you have a problem go to Helen Wait.
I put a zerk fitting on gear case on my big Black and Decker from the 70s still going made in USA…
Well what I have gathered is if they're cutting rebar they will totally cut the guard off because the guard ubstructs their ability to cut the rebar!!
Thought you were going for a Bob Ross quote when you were painting the gear. “We are having fun hereâ€. 🤣
As a teenager I worked at a power tool repair shop. Doing things like this was what we did, new switches, new cords mostly. We would have ordered a new gear assembly. Sadly there are no power tool repair shops anymore execpt in this guys garage
I'd think the locktite would heat up and release, but who am I to argue?
And i thought I had too many grinders
Best part might have been Lily's cameo at the end Thanks for sharing
