Good advice👍

I'm an old master aircraft/heavy machinery mechanic. Always take both seals off and clean then inspect them, if the bearings are good make sure the old grease is all cleaned out. There is a thing called "balling" which is where two greases are not compatible and cause the grease to react and dry out making little non lubricating balls and the bearings will fail. we had some mishaps with F-16's having this problem when the wrong grease was used.

My God, how can supposedly grown men watch a video about greasing small engine equipment bearings and within a few posts start calling each other names and trade insults? It seems impossible to post any how-to video on youtube without hot-headed know-it-all keyboard experts chiming in to tell the poster how they are wrong and demonstrate to everyone how smart they are. Most seem to have never posted an actual video themselves, they just arm-chair critique others' videos. So all you self-proclaimed authorities on bearings- calm down. It is a bearing on a piece of garden equipment, not an F-15. Thanks for the video, Dony. Ignore the self-important twits in the comment section. We adults appreciate your efforts.

I've been doing this since the early '70s. The metal shielded ones get soaked overnight in solvent, blown out with compressed air, heated in a pan of proper lube, then the pan / lube/ bearing are cooled. Works great for hard to get parts, especially for obsolete equipment.

That was an awesome tip. I have never heard of anyone doing this. After talking with several friends who are mechanics, they all assumed that I knew to do this. It is nice that people believe that I am sharper than I actually am.

Who said I can't learn something today? I just learned how to grease a sealed bearing, thanks Donyboy.

In an emergency you can temporarily extend the life of a slightly noisy bearing by completely removing all the grease washing it in solvent and gently blowing out with compressed air and repack it with grease but leaving space for expansion inside the seals. You need to choose the correct type of grease for the application it’s working in as not all greases are created equal. Once the balls, rollers or race have become pitted replacement is the best option. Sometimes if you have an oddball sized bearing this is your only option until you can procure a replacement. From many years working as a machinery fleet mechanic I would sometimes have a sleeve machined up so I could fit a common over the counter bearing to replace hard to get oddball bearings that some machinery manufacturers thought would be a good idea to fit. 😀

Thank you Dony Boy. I was planning to replace the sealed bearing in the head of my angle grinder. I repacked it with new grease instead, and it runs nice and smooth now.

Thank you. This video saved me 40euros. I was replacing wheel bearings yesterday and got sand in new bearings and i had to wash all the grease out to get the sand out of there. Now i know how to re-grease them.

AWESOME!! Have been working on engines forever and never thought of this!!

i never knew you could get those covers off! thanks for the video. tip for packing the bearings, put a rubber glove on your left hand, some grese on the heel of your palm, press the bearing in it repeatedly with the other hand. this forces the grease through and works really fast.

All these years and I never realized they were that easy. Thanks for the video. Good info.

I have been a small engine mechanic for 20 years and found this very helpful. a lot of people are not aware that you can do this!

This is the best tutorial I have ever watched on youtube. Video is clear, high definition, focused the whole time. Voice is loud, clear, moderate speed with easy to understand accent. Varies types/sizes of bearing is demonstrated. Nice work!

You should actually start from the inside edge of the rubber gasket. The rubber on the inside is much softer, and won't get damaged by the pick that you use, since it just folds out of the way. If you try to remove the gasket from the outer bearing race, you can tear the rubber and potentially damage the brass below it, meaning it wont seal as well when it's reassembled.

i never knew that could be done, I learn something new on your channel all the time

I did this on the bearings inside the hubs of my bike they run smooth again and it saves me money so thank you!

Great, good advice. I'll be checking all my rubber sealed bearings from now on.

You made me feel better, I've been using these methods and more for years, never had a problem, thanks.

That is one of the things I learned while in the Air Force since we had trailers which had to be greased on a regular basis to keep them from breaking down when we needed them most. Thanks for the tip, and I hope you are having a nice week.

I cleaned and greased the bearings on both idler pulleys on my Jeep Grand Cherokee, using this method. Worked like a charm! Many thanks! Cheers🍻!

Great tip, used it on my mower deck idler pulleys. Way better than spending 30 bucks apiece for pulley/bearing combination.

Thanks. Very useful. I needed to reseat the cover on a bearing, because of my ineptitude when pressing the bearing in. This was most helpful

Like the video. it's amazing all these people have so much negative to say. For cryin out loud it's about greasing a bearing, it's not like he's greasing an aircraft carrier.

Great advice - sometimes when your searching on KZfaq you come across a video that is quick and straight to the point - excellent 👍

That is a good video! I am a vacuum cleaner repairman and sometimes try this method. Sometimes it has worked and sometimes it hasn't.

Fantastic demonstration and video. I'm hoping not to wreck a sealed bearing and this video was just what I needed.

Awesome! I didn't know this was possible. Thanks for posting!

Thank you sir you saved the day! The top spindle bearing is the same bearing in my Husqvarna, so I used an old spindle bearing. It only had a seal on one side though, so I pulled the seal off the idler bearing and used it on the spindle bearing.

On our farm machinery, we drill a tiny hole in the metal sealed bearings and then use an injector needle. A dab of caulking then seals the small hole. The easy to reach bearings just get replaced, but some take hours of disassembly to get off, so this is were the injector needle comes in handy.

DonnyBoy, I need my mini bike tomorrow and didn't know how to remove the bearing seals. For the information of US residents, Harbor Freight has a set of picks that's often on sale for around a dollar. Mine worked fine. Thank you for the video

Thank you for sharing your knowledge and experience. Great video. You saved us many headaches and money. Do not stop sharing your skills.

Thank You for this video. Just saved me almost $100 in bearings.

I have to say I watched your video 2 -3 years ago and ever since I have checked every sealed bearing I’ve come across. I will tell you about 1/3 of new bearings I’ve purchased have had either no grease or very little. I would strongly suggest everyone watching this video to check your bearing, especially if they are critical !!! Like motorcycle wheel bearings.

excellent.i will be doing this to my idler pulley bearings very soon...thank you.

Excellent! Thanks. Who would've thought it was so easy.

thank you Don , I never knew this , very helpful how to video . Sharing with my friends .

Thanks man! Never knew sealed bearings could be reused like this

Hi Don, love your channel. I re-grease snowmobile bearings used in the rear suspension wheels. They take a lot of abuse. I remove the bearings from the wheels with a press after removing the snap ring retainers. I remove both seals using a precision screwdriver. Bearings are cleaned in a jar with mineral spirits, followed with a blow gun with the bearing in a clean rag. Then, I spin the bearing to see if it has any resistance and check for pitting. If all is good, I use moly lithium grease and reinstall everything. This really extended the life for these extreme use bearings.

I did not know this could be done. Very good to know. Thanks and have a good weekend!

Good video. I usually remove both sides, soak it in mineral spirits to remove the old grease, then pack it with new grease.

Thank you for this. I have 2 wheels that seized up after I rode through a flood, (didn't realise they got wet :-(. Managed to free them up with heat and light oil, followed by thicker oil, but grease would be far better! I shall give this a go!

Love this guy.....Thank you Don

Thanks Donny I always learn something from you.

Great vid thanks. Just a few points, after prying the seals out there is usually bending, so before reinstalling check you flatten the seal out perfectly. I always use a good quality "water-proof" grease as this type of grease doesn`t get washed-out so easily. Don`t buy cheap bearings where ill fitting seals don`t actually keep dirt & water out, the main cause of bearing failure. Finally as this vid points out don`t over grease the bearing. I always take off both seals squeeze the grease but leave a finger groove in the grease so as not to put pressure on the seal.

Excellent video. Thank you Donny.

I never knew that you can regrease these bearings. Thanks

Another excellent video. You definitely have good teaching talent. Very articulate.

This will work been doin it for 40years! Never had a problem.

Guitar pick works great too.

Learned this trick 46 years ago....good to share. God Bless America

Excellent video - Many thanks !

Good idea to clean the bearing from old grease with benzine . If you reach the point where you need to do this the old grease is usually hard and makes the bearing rough and new grease wont solve the problem. So clean it out first and blow it out with air and the bearing usually becomes smooth and then you insert the fresh grease.

What a good set of videos. So easy on most things. Very helpful. Thank you Don!

Wow! Just learned something new! Thanks!

Great video. A natural teacher.

Clutch "Throwout" bearings come to mind for this great tip....

Great lesson! Thank you.

I really enjoy your channel. PhD is small engine and machine mechanics.

Excellent video , no guess work needed .

Simple yet very informative cheers

Great video man was thinking i couldnt re grease these bearing thanks alot

Thank you! Similar technique based on this video It works on dura ace 9100 hollowtech bottom bracket.

You saved me mucho denero thanks. Koyo tensioner and idler pulleys go for 35 dollars and up especially for lexus vehicles

For small high speed bearings like alternator bearings or idler pulley bearings, that see sub freeing temperatures, I use a thinner lightweight grease. Heavy grease will spin the bearing centers sometimes if you don't use light enough grease or too much grease. too much grease causes a bearing to run much hotter.

GENIUS !" THANK YOU FRIEND !" YOU DA MANN !"👍

Great tip Dony... Thanks !

EXCELLENT DON THANK YOU FOR SHARING!!! I NEVER KNEW YOU CAN REGREASE THEM NICE!!!

Nice I thought I was going to have to dig out my dad's needle that's how he done it but as you say under pressure or speed it spin's out. Thanks Donny boy for your service.

Thanks a lot! Now I can enjoy riding my bike with friends.

this video is very helpful with a lot of information thank you so much for sharing.

Enjoyed your video, I’m a new subscriber and look forward to learning the proper way to do maintenance on my snowblower, etc.

Great advice, I use Lucas Oil red n tacky. Brake clean the cheap stuff out, dry, and apply

Very good information... Thank you...

Great Video!! Thank You!!👍🏻👍🏻

Hey Donny Love your work! You're my favourite Canadian.

Thanks man! I'll be repacking my freehub bearings!

Great 👍 video. Doing this job in the morning.

my alternators will appreciate this a lot! thanks ;-)

It's best to clean the bearing out first to remove any contaminants and to remove the old grease which may not be compatible with the new grease. You also want to push the grease into the bearing, not just wipe it across the top like you did.

Hey, cool stuff! Obviously a tradeoff/decision to make between replacing a bearing and just re-greasing it like this, but for things that aren't critical bearings (failure isn't going to destroy stuff) this could make a lot of stuff more salvageable!

Nice video. Now i'll repack the bearings on my bike.

I've bought quality bearings that literally had a pin head of grease from the factory, so before installing I will always grease a sealed bearing. It's easier being happy ! Thanks Donny, good Vid !

I like to use the injector after removing the cover. Easy to get grease on opposite side of the bearing. RichE

A feeler gauge works awesome for removing the seals without damaging the sealing edge. Over packing the bearing could lead to failure depending on usage. Nice vid.

You have the best videos. Very good explanations and step-by-step methods. Great photography. You are the man.

appreciate for the good idea , it is not always able to find the exact bearing , especially when it is a old tool ,thank you !!

Great information Thank You 🙏

Great Video, Thanks!

Thanks, I didn’t know that was possible. Great channel!

Excellent video.... I just learned a few things from this video..... when and where the different types of bearings go, and for what reason.... I learned that I can remove the seal and tool needed for romoval, in order to grease it, I also that I could do this in any situation , no matter the application it is being used for at that particular time, same process carries across the entire field of bearings and races... So 👍👍...

Thanks Dony, really great information.

Thank you very much for this video!!!

Thank You Very Much; Just what I needed to know on the Sealed Bearing's on my Swisher Blade spindle. Thank You So Much for Shareing.

I repacked a couple of idler pulleys on my mower deck. They run smoother now. I had already replaced one, and repacked that one to replace the other one. Now I have a spare that is repacked and ready to go if needed.

Thank you, I tried this method with my idler pully on my engine. I took off the covers,cleaned it out then regreased it. The only thing was it didn't get rid of the sound (I'm guessing it is already damaged) so I'm going to changing it, but I'm glad to know that I have experience doing this now

great trick!...thanks for sharing

Wow, the needle injector for ball joints... that is GENIUS.... I've only ever regreased a ball joint once or twice because I would take the ball joint off the car, take it into my work shed, clean the grease out, then put the new in and replace the boot.... this doesn't risk contamination and it's so so much faster than that. P.S. I tried adding grease while it was still attached to the car, but since I work in my front yard in Florida there's grass, dirt, and especially SAND that blows up all the time. Just one quick gust of wind and sand is in everything. It's really difficult to keep a clean environment when if you accidentally touch the ground and then what you're working on again particles of sand will be in it :(

Thank you, this is my type of 'how to' video

THANK YOU :D buying grease tonight for my longboard bearings ;D
