- Some tips for making bearing removal easier.
If you need a new bearing, don't forget to check out places like Amazon right here: amzn.to/2h5Pi8N type your bearing # into the search
You use the same method for taper bearing races.
If you have a blind bearing, you'll need a kit like this amzn.to/2h8Ms3w
Well, I am not a teenager, so I don't claim to know everything. This was OUTSTANDING !!! In all my years of messing with stuff, I would have never thought to do it this way !! Thank you so much! And Merry Christmas to you and yours.
Thanks Man.
glad to see you use a ziplock bag. I have seen so many videos where a mechanic wraps a bearing in a moist paper towel and steams the bearing in the microwave. Steam, as in, adding water to the brand new bearing!
Instead of water, I just use a heatgun and warm it up until it's hot to touch (use gloves) but not cooking the grease (or seals if it has them). (tip: put it on a screwdriver instead of trying to keep your gloved hand in front of the heatgun) I've used a torch in a pinch, but it is easy to cook the seals that way.
As far as removing, I usually start with a puller. If it doesn't come off with a puller (and maybe a quick try with the torch while using a puller), then i find it very quick to cut through the thing. If the puller didn't rip the outer race off, then I just cut it near perpendicular to split the outer ring and cut through the cage at the same time (much faster than a diagonal cut for the outer parts). Then pop those off with a screwdriver and cut through the inner race diagonal like you.
Other Tips:
*for press fit installations, the old cut-apart bearing pieces only take a quick (power) sanding/grinding to make them small enough slop fit and are the right sizes to push the new bearing in.
*If you aren't in a rush, you can put things in the fridge or freezer to make them even smaller and combine that with a heatgun or torch to make fitting several layers together much easier. Use contact cleaner to make sure things are dry afterward.
Great video... your direction worked perfectly in fact it took less time to do than finding a puller in my workshop! Thanks.
A guy I worked for back when I was a teenager would always sit the new bearing on top of a light bulb to heat it. That also works great. If you still have any regular incandescent bulbs.
That's a great tip!
yeah but i dont believe these modern day light bulbs would get hot enough, They suck lol
Rodder Files LOL I said incandescent bulbs. The CFL's and LED's would not work.
I like the disclaimer, got a laugh out of me. Good video, as usual, you seem to always teach me something that I didn't know I should know. Thanks.
Thanks Chris. -Moe
I'm so glad you said single phase instead of two phase. So many people get that wrong. Thanks for the great videos.
Thanks for watching.
I was stuck removing one so searched and came across your vid - One dremel later and its orf! Cheers Mr Sixtyfiveford
Awesome.
I came here because my internet is down and I need it fixed.
Great video. Happy Motoring.
Thank you so much for the tips! I was trying to remove the old bearing on a logitech g27 wheel, i heated up the old bearing with an air solder station for a bit and it was a really easy removal. So once again thank you!
I thumbed up Chris Hoyt's comment because that was exactly what I would have said. Great video and your never to old to learn. Thanks again. Have a great week.
Thanks Tom. Hope you have a great week as well. -Moe
I wouldn't think hot water would heat the bearing that much but wow, it worked! Great job as usual.
Just trying to heat it up but not ruin the grease inside with too much heat.
Great explanation as to why a puller doesn't work as well as just cutting it off. I was surprised the new bearing expanded that much and didn't have to be "tapped" back into place too. Thanks Sixty-five!!
Thanks.
You always teach this old dog new tricks. Please keep them coming.
Thanks for watching Bill. -Moe
Nice video but I want to know how to pull good bearings without destroying them. Sometimes I find old motors with good bearings and only want to salvage the bearings for future projects. But thanks for the video. I am very good at destroying things without watching a video. :)
Hey man you channel is better than Beakman's world! greeting from Chile!
Wow, thanks.
On the production line I worked on ages ago, we used to put the bearings on a metal bar that swiveled. In the closed position, it completed an induction coil which heated the bearings up, it got them really hot, really fast. Meanwhile, the axles were chilling in a freezer... .
That's neat.
Excellent tip/video on removing the tin cage! I can see where there will be a time and a place where that would come in quite handy. A friend was talking to me about those battery powered snow blowers and then you had that video. That looked like a well built unit and figured you will put up a video of it in action when the snow arrives. He don't do much YT so I will tell him if you post one on that. Take care Moe, Jeff.
It hasn't snow much yet, but I was impressed by a few inches on the lawn that I piled up. I think it has the power to handle almost anything I put in front of it, I'm curious how long it will run.
I use an old gas grill to heat up bearings, but boiling them in sealed bag makes more sense. no more cutting the outer race either!
The gas grill works great for cooking out grease and oil from riveted brake linings (this will not work on bonded linings as the glue will burn off also) and clutch plates that still have a lot of life in them. Do an initial burn off, let cool. Clean up in the parts washer, blow off with compressed air and put back into the grill for a second cook off. When cool, take 120 grit sand paper to the lining and clean up with fresh mineral spirits.
Don't forget to repair the leak that caused the mess to begin with.
I've used a torch to do brake shoes and it takes forever, but I like you grill idea.
I've used this process on field tractor linings a few times, you know, someone replaces a set of shoes or discs on one side, cleans up the leak without repairing it and the $50.00 set of linings are oiled up again.
When you cook off a set of linings you know they're getting hot(turn the burners up high and shut the lid) when the grease n oil are smoking out and you know when it's done cooking when it all stops smoking!
After all this that grill has only 1 purpose in life, and it isn't food.
Great idea Moe! You made that look like child's play! I'll boil a bearing like this next time I have to replace one!
Thanks Man.
The last bearing that I R&R was on an EMD 645 main generator and used a hydraulic porta something and an heater designed for the bearing which weighs easy 75+ lbs, this brought back great memories.
Thanks for watching.
ive had to do that on pump truck little front wheels .. I took a grinder then pounded them on with the right size pipe.. its still working great.. .. please show how to fix a pump truck that wont go up anymore even that I added more oil.. thankyou..
George foreman grill works well also on bearing and a dremel will also gut right through a bearing race . Good video
HAHA terry that the best use for that grill.......
The George Foreman, I haven't heard anyone talk about those in quit a while.
Never thought of the hot water trick! Also like your explanation at the end of why a puller is not the best choice.
It just keeps the temp low enough to not destroy the grease inside. I've taken that tip from other people but have also just heated them up with a torch multiple times(slowly, just above holding in your hand comfortable temp)
That is one big ass motor! You won't be warm next summer when the A/C is running
It's so heavy the Fedex guy made me come out to the truck and take it off.
lol
No. Cutting the race should be the last option.
A puller is the way to go. The bearing will slide right off, just like that.
Agree to disagree. A puller runs the risk of galling the shaft and other damage. Slightly cutting the inner race makes sure this damage doesn't happen.
This is the best tip, everybody needs to know
Yep been there.I had to use torches on this one job on a 4 inch 40 ft shaft for an air handler.was way cheaper than getting a crane and pulling the whole works out i saved them so much money. 3 day job done in less than 8 hours.
That's a big bearing.
This helped me a lot. I was looking at all sorts of gear pullers/3 jaw pullers. Just used the cheap dremel tool I already had with a cut off wheel.
a good companion to this video would be methods of finding the replacement bearing. from using parts lists to correctly measuring old one
Yep i see where i been going wrong all this time. thats a very clever way to remove bearings brilliant video
Thanks Man.
Those air grinders are the best thing to have. Used ours many times to change old bearings saves a lot of time.
They use a lot of air, but last forever.
Thank you for your advice. I realized I needed to put mine in the freezer, easy work after that.
I always learn something new from your videos. Thanks for sharing them.
Thanks Dave. -Moe
I could use some tips... i have a set of bearings i need to remove so i can put in a upgraded set. They are 6220rs press fit inside a Jack shaft of my "2020 phatmoto rover" motorized bicycle i tired to hammer them out but i think there is a inner lip like a cup holding them in built into the seat tube. Cant cut them and heating is limited...
I do this some times when I'm re building a commercial ext fan for a vent a hood at work
There are several Great Procedures and Ideas revealed in this superb video. Sixtyfiveford, thank you so much .
Question 1: In general, is it OK to heat pre-greased and sealed bearings to 100 degrees Celsius? The grease does not leak out at this temperature, does it?
Question 2: How did you install the "housing" of the new bearing, please? (I refer to the component which comes in contact with the outer ring of the bearing). Was it possible to push the housing on the bearing by hand? What to do when it is not easy to push the housing on the outer ring of the bearing?
I've never had an issue heating the bearing/grease. For internal fitment you can freeze the bearing to allow clearance.
@@sixtyfiveford Many thanks for answering my questions. I greatly appreciate your help. 👍
I use that kinda deal on axle bearings . No reason to fight them ! great share Moe .. Thumbs up
Thanks Shawn.
FYI to anyone trying this. I threw my bearing into a sandwhich bag that leaked and moisture ruined the bearings. I want to try it again because they didnt get hot enough to slip onto the shafts. I will try a freezer bag and put then in boiling water for what like 5 mins on a rolling boil?
I never though of doing the heat method with bearings, we used to freeze cylinder sleeves to insert them into tractor blocks though.
You just need to not get them too hot or you risk ruining the grease.
I can see why the hot water would work good.
Ha! I love the public service announcement to Subscribe at the end of your video..LOL:)
Crazy that the internet would just be over. I'm glad it continues on.
Wait what happened to my internet? PS great tip, I would never have thought to remove a ball bearing assembly like that.
Thanks.
crazy that i just stumbled on this video. few days ago i nearly took my dome off when applying a crazy amount of pressure with a bearing puller in attempt to remove a very stubborn bearing. it exploded and thrusted the two foot handled ratchet and large puller straight in the air missing me by inches. had i seen this video first? three hours gone never get it back. thanks for the video
That's scary; keeps you on your toes. I've put a scary amount of pressure into these pullers and have had them break violently a few times.
I have a 65,F250 4x4. Have one for sale in WY 65 F250 2x.
I've seen guys use oil instead of water to heat a shielded bearing and then grease the bearing after instal.
Nice Work, excellent presentation.
Can You PLEASE show us how to remove spherical plain bearing ge-g, ge-gs type 20mm/0.78in bore fitted/ pressed in ?
An internal pressed bearing can be heated with an oxy/acetylene torch and flash cooled to shrink it. A few spots and it should just fall out. You could also slice it but a 20mm is tiny and it's unlikely to fit an abrasive or diamond blade in there.
I liked the the lesson at the end. I did not know the bearing causes a wedge for the puller.
Thanks man.
smart son of a b!t(#!
every time I watch one of your videos I think "ya I know all about this". then I learn something new! great video!
Thanks Darin. -Moe.
anyone else here because you thought bearing's channel might have been restored? #freebearing
You just made my day. Its gonna be so easy.
Hey Thanks, I'm glad you liked it.
Great video and love the security spoof at the end
Haha.... Thanks.
i guess that's a dumb question, but then what the pullers are good for then?
Applications where you have no room to cut the bearing race off.
I take it you don't have to grind all the way to the axle just cut a groove?
Generally just 3/4 of the depth and it easily snaps.
Things I've learned working on stuff. Most things are prybars everything is a hammer lol
A hammer gets a lot of things done.
Yea I've used the pullers and heat or cold, but I think I may try your method next time. Thanks for sharing !
I've never had great luck with pullers, maybe because I'm always working on old rusted stuff.
sixtyfiveford Good point. Come to think of it, most (if not all) of the stuff I had to pull (not often) was rusted also. But there were a few special times it was an internal bearing with no rust but lots of either greese or oil which had to be cleaned or the pullers kept slipping off - haha.
Anyway, glad you got that one off. That motor will last for another 20 years now. What are you using it for?
It's going on a huge industrial air compressor.
This is how you learn by doing hands on. Great tip Moe .Oh ya i tried pulling it off hahhaha
Thanks Steve.
2 Thumbs up on showing how it's done the easy way !!!
Thanks
I would think you would want to cool or even freeze a bearing of you were pressing it into a steering knuckle in an automotive application. Great video as always.
What's the point? The bearing is going to be at atmosphere temperature 99% of the time. If you made it contract by freezing it, it would only stay contracted as long as it was cold -- same way as it works when hot (and thus why his method of putting the bearing on works)
Not easy, but helpful. Thanks!
That looked too easy. Where'd you get that Craftsman shirt?
I just bought it from Sears a few days ago. I walk in and really don't need any new tools, so end up buying a shirt to keep Craftsman in business.
News does not look good for Sears/KMart. Sad to see that.
Another easy and funny video from Moe. thumbs up!
Thanks Robb.
Brillant thanks for sharing your technique
You can actually take the back off and remove the entire shaft and press it
Best advice ever! And good explanation too❤️👍
Glad you think so!
Oh so you have the red on/off internet button today!
:-)
Cool Big air compressor for you coming. Video coming too ??????
It's a huge 80 gallon monster.
Good job, Moe. Good tip for other applications too.
Thanks George. -Moe
How about a heat gun on the bearing? Missed the doggie
I call them prydrivers.
That's a great name for them.
just what I needed to know - thanking you so much.
@65ford 👍👍 my men i should come here 10 videos ago thank you buddy 👍👍😎🇺🇸
I would have used a baring splitter
Great practical explanation thank you
Glad you liked it
another great tip
Thanks Man.
Impressive thank you
Thanks for the tip Moe.
Thanks.
good job
just like how we do the big ones except we cut the cage off and use a bearing heater. You know it's ready when that son bitch is smoking literally. Then it's off to the races literally because you might be 200 ft in between the piece your working on.
nice job.
Josh Kilen Thanks man
God damn good video
Nice Repair Moe!! Zip~
Thanks Zippo
thanks mo very useful info.
Thanks Jim.
well done :)
LOL who ever the hell cares :-D, i do.
I have never really thought about the action of pulling the outer race of a bearing.
Thanks for your wisdom, ill remember that :-).
I have to admit, an old screwdriver is a handy chisel, sacrificial, not allways used propperly, but if it gets the job done, its worth it :-)
Hey Thanks.
cool shirt
Thanks Man.
