Thanks So Much i Spent 900.00 On Mine Just Like Yours !~~ After ten Years Motor Bearings Or Something Gave out Today Just after Paying 1900 on a root canal last thing i needed was Replacing My Bosh Table Saw 4100 Right In The middle Of a Deck Job Packed Her Up Brought Her home Tonight Ill Take Her Apart And Check My Bearings THANK YOU !~!~
Thanks for a very easy to follow procedure. My 4100 smoked up my shop today as the same bearing seized and burnt up the rubber ring that holds the outer race. You saved me a bit of time I would've spent figuring out the best plan if action. Great work! A minor note/tip: When driving a bearing onto a shaft, it's best to apply pressure on the inner race only. Conversely, driving a bearing into a bore should be done with pressure on the outer race only. Thanks again!
Yep i have the same saw and mine is starting to make a noise now that was my first assumption the bering is going out Saw is 4 years old and has ripped a ton of 6×6 oak Thanks for this step by step video much appreciated 🙏 👍
Wow, thank you for the sharing your experience. What a great explanation. The woodworking folks will certainly benefit from this. I really appreciate your support. 👍👍👍🙂
Great video. I notice you forgot to mention the rear rubber cup that goes off the end of the bearing in the housing for stability. I was lucky to grab this same unit for $150 from a carpenter down the street from me. He retired and didn't want to bother with it as it sat for over a year. He new it was bearings and my hunch was that too. Sure enough, the rear bearing was shot but the one in front of the armature when spinning by hand had a resonating sound, it could go out in a year or so. Once the armature was out. the front bearing did have signs of being on its way out. I'm replacing both front and rear bearings with new brushes. It should perform nicely after completed.
@@TheTrullGallery that’s great. It’s easy to miss. I’m waiting on bearings and a puller. I was able to nab a dewalt compound miter saw dws779 and stand as well. Changing out those bearings as well. Same situation. One Bearing is a bit tight to the fan fins on that armature so need a low profile puller verses the one from harbor freight.
Great video! I had to replace the same bearing. Just a heads up... That is a VERY common bearing. It is available and stocked at Ace Hardware Stores for around $4.00! Again, great video. Thanks.
I don't recall you mentioning changing the rubber gasket that goes over the bearing. After looking at the parts manual I noticed there is a rubber gasket that goes over the bearing. Mine was shredded when I took the motor apart to change the bearing. I don't know for sure but I speculate because the motor housing is plastic and a worn bearing would destroy a plastic housing, I wonder if the purpose of the rubber gasket is to melt under heat and stall the motor so more damage isn't created. It's less than a $3.00 part.
I have the same saw and have not had any issues....yet. But you've shown me what to watch/listen for and how to fix it. Still hoping you'll figure out a way to install a small infeed table somehow 🙂.
True - that's not necessary IF you know for sure that the rear ball bearing is a problem. But it could be another (front) ball bearing or the gears. Then, you have to dig in through whole machine and, as such, the other video is more informative.
Hello my name is Richard, and I am interested in buying the Bosch table saw. Could you please tell me what you think about your Bosch saw, like is it worth buying, and how long have you had yours, and were you satisfied with it overall. The plastic gears are causing me concern, but your main bearing went out. People are saying how disappointed they are with these plastic parts. Did you like the way your saw performed? It looks like you used it plenty, so I value your opinion. I was all set on the Bosch over the Dewalt and the Skilsaw, but I started hearing horror stories about the plastic gears. I appreciate that you showed the underneath view of the bottom of the saw. So please can you share with me your opinion about this Bosch saw. I really want to love this saw but I’m apprehensive about the purchase. This saw seems to fit my needs, being smaller out of the three. This saw would be at our summer home and not used everyday, so I’m hoping that this saw would stand up to my workload, it wouldn’t be at a job site being used day in day out. Well your Bosch looks like you got to know it pretty well, so I’m interested in your opinion. Please could you comment on the pros and cons of what you’ve experienced with this saw, because I would greatly appreciate you view? Thank you so much for your time, and I hope you respond. Richard
Hey Richard! I've had this saw for over four years, and I treat it like my old cabinet saw. I think the bearing issue was from tuning an extension cord too long (I've remedied that). It's getting a bit tired, but I use it a lot! I miss my Unisaw, but I'd buy this one again.

I'm glad it helped. I know better than to just beat on a bearing. I don't know what I was thinking. 😅

Yeah, I found out about that rubber cup after the fact. It's running well now!

Great explanation, visually and verbally. Thanks very much.
Glad it was helpful!
Great job brother!
Thanks Eric!

Good to know. Thanks !
I don't need this fix yet, but I like the patience you showed to let me know the trouble areas and where I need to pay attention.
😀👍👍
With any luck, you won't need this repair!
Great video , I do wish you’d posted links on the part numbers for bearing & brushes .
The part numbers are listed in the description.
@@TheTrullGallery thank you
Nicely done Dave.
Thanks!
Thanks, I learn something new today.
Cool!
Just did my bearing and brushes thanks to this video! The hardest part for me was getting that gd puller on it!! 😅 Thanks!
Nice! That puller is a challenge!

I found out about that part a few days later. And mentioned it in the next video...

My saw is three years old, with LOTS of hours on it. Aparently, this is a fairly common failure point. Keep an eye on it.
Good video,very infomative. You asked for comments. You could have provided the bearing part #.
Thanks! The bearing part number is listed in the description.
I watched another video on this problem, he disassembled parts on the blade end which is apparently not necessary. Thank you!
True - that's not necessary IF you know for sure that the rear ball bearing is a problem. But it could be another (front) ball bearing or the gears. Then, you have to dig in through whole machine and, as such, the other video is more informative.

Thanks!
Thanks for video.
I have a little side to side wiggle on my saw blade.
Is the bearing you replaced control the play I’m finding?
Hmmmm.... I'm not sure. Reach out to the tech guys at Bosch. They were super helpful troubleshooting my problem.
Thank you, excellent.
How they can put put an unsealed bearing on a table saw.
I think It was sealed... until it failed. The replacement was sealed, and there were remnants of the old seals in the motor housing.
@@TheTrullGallery so it was the normal wear and tear. Dust and heat is hard on bearings. Keep it up.
@henrysara7716 thanks! Since the tech at Bosch knew exactly what part I needed (from an email description), I'd say it's happened before.
