Remember that WD40 is NOT a lubricant. If you're applying WD40 to a bearing thinking you are lubricating it, all you're doing is diluting and rinsing the factory lubricant from the bearing.

Hey Ryan! great video, here are some of my tips: 1. Clean your entire motor case using a vacuum cleaner with a dusting brush attachment, don't vacuum delicate electronics. 2. Run your motor un-propped make sure it sounds smooth. 3. In any case of grinding or other unusual noises, I would usually replace the bearings and make sure rotor doesn't come in contact with the windings, (it does happen). 4. If you're about to replace your motor bearings, be very careful when taking it apart, screws are often fragile or tightened with thread-locking adhesive. 5. DON'T HAMMER! Use a a press/vice when dealing with tight bearings on a shaft, if needed, carefully use a rubber mallet. 6. Use Corrosion X (mostly for RC Boats) All the best, Eden.

Very good information.

Thank you for all the videos, love the info and presentation! A question about bearings. I have a rc plane motor I need to change bearings on and can only get normal bearings that are used for rc car wheels. Would this work or do I need some special kind of besrings?

great video ryan!

Good stuff buddy

Inside my motor and armature are packed in dirt. Arrma let’s a lot in. So no contact cleaner in motor can or armature? How can I clean them. I tried a rag and it won’t come off. I read people said spray contact cleaner but many say not to, also what do you think about blocking unused motor holes etc to keep dirt out. Are these also vents for heat. I don’t want to fry my motor trying to keep dirt out, thank you in advance. This is for typhon 3s

I think one thing that was not mentioned in this video is the working temperature of the motor because in my opinion if it is too high it will dissolve the grease in the bearings and it will go out just letting the bearings dry and so reducing their life due to excessive wear.

Hey Ryan no one in the comments asked this but what is the lifespan of a motor bearing?

I have to agree with the basic message in this video that when it comes to motor bearing lubrication, it sure is a case of "less is more".

Love your videos and your allot smarter that me. However, for standard RC use I can see your point. For high competition Racing you want the most of your bearing. A lighter oil helps with rotation and cuts down on drag. Its nothing for us to replace bearing if they get worn out and go to a ceramic bearing. Again, we do allot more maintenance than standard use.

thanks for the advice my wltoys motor is brushless and it cost with shipping included $16 dlls and the lifespan of my motors usually last about 2 to 3 years so yes instead of replacing bearings for me is easier to buy a new motor after 2 years the cost for me is about 0.02c per day

So basically if I can turn my motor over without feeling and slop or hearing any grit I’m good? Had a few bearings near my wheels and rocker arms on my e revo 2.0 go after a particularly wet run

So if a bearing seems to be squeaking in a brand new BL motor would i need to lubricate it or what would you say? Or would you say just clean it with some electric contact cleaner?

Wondered what your thoughts were on cleaning a brushed or brushless motor with motor spray? Seems like it was more common 20-30 years ago and not as common today, but there can be bearings in both kinds of motors. 🤷🏻‍♂️

What grease does the companies use? Weight, viscosity, chemical make up? Thanks.

Would graphite be a good alternative to help the bearings. I use it on the bearings in my 3d printer and it did wonders for them.

Hi what gear oil would you use on a 350w rear geared hub motor for a e bike? Many thanks

If I may, I'd like to add my 2 cents: In RC boats, I like to make sure that zero thrust from the propshaft is directed through to the motor bearings.

Hello I have a question how can I calculate or see the minimum current that a Brushless-Motor need

I would NEVER go through all that but if I did I would use Graphite as a lubricant . Super slick and it is dry !

Interesting way of saying PROCESS. I like how you say it the British way Anyways. Do you think I can clean my Traxxas VXL motor with electronics cleaner?

This is important. Not just lubrication but maintenance of brushless motors itself.

I've always put a drop of 2 in 1 in the bearing on rear of motor...

spraying lube will just cause dirt to stick to it and fail faster. If its dry dirt won't stick so much.

My motor took a little salty water and the bearings sound dry, why you recomend?? Is a new motor only five runs

What if my quad took a dip?

And what do you do if you already have done it with WD-40?

The old school guys know not to wash out the bearings as mentioned here and why. The new guys have to learn the hard way lol

Thanks mate. For me it is clear; Don't lubricate your engine... if they wear put new bearings in it.... :-)

Use zx Schumacher bearing oil

I use fishing reel oil on my bering I've got hundreds of hours on my motor 😐👍

You need a camera for close up shots.

Bearing seizes up ?? Buy a new motor !!

could of madethis video just 30 seconds long....Do not bother lubricating as they are cheap to replace and will last longer..... end of.... all that waffle for a simple no.
