Just about to change bearings in my T4 so watched this video to see if Begode is doing things differently from other EUCs, but it seems easy enough. I did notice you forgot to put any bearing glue on the new bearing. I am changing bearings in my T4 because of bearing knocking which happens when the manufacturer forgets to use bearing glue (common problem on S22 for example). I also didn't see you use any silicone before you put the motor covers back on, so the wheel is not waterproof now.
Dawn is hilarious. After all this time, I'm surprised she hasn't figured out that EUCs are not motorcycles nor even bicycles to cut across deep (or unknown depth) puddles & streams without nary a thought. O well, I'm hopefull she'll stop & push it across next time 😁. Thanks for showing up how to swap bearings Roger 👍
Thanks for the video tutorial. I am in the middle of replacing the bearings on my Commamder Mini. I was able to remove one motor cover and insert the new bearing,. I confused though on how you were able to remove the other motor cover, the one with the power cable exiting it. It is still attached to the motor and axle. Since the power cable is obstructing placing the large socket into the axle hole to bang the axle out of the cover and bearing, how were you able to work around this issue to release it? Thanks. The socket wrench attachment hole in the socket is not big enough to feed the cable through it either.
Why not use a torch to expand the metal to remove the bearings easier. What I did replacing my bearings. Not really sure it was much faster though..lol
@@roghaj Ya sometimes we can overcomplicate things. Your approach made look much easier. People are afraid of using fire...lol

I used heat to warm up the covers. That way no hammer was needed. Getting the new bearing in... just fell in. Then when the cover cooles down to normal temp the bearing is stuck like it should. Using a hammer can very easily damage a new bearing even with the home made tools ;)
So I did replace the bearings on mine, but I've heard that there is a risk if putting the motor back together the wrong way and making it face plant when turned on. How true is that ? I think I made enough photos to put it back the right way do you have tricks or recommandations ? Thanks:)
Hi Roger I recently put my extreme underwater for around 10 seconds, no moisture in battery packs but I have a BMS alarm on, we are replacing the charge board and hopefully this will work. Wheel still balances so you think I should replace the control board as well also there was a lot of water in the motor any advice from you would help thanks Paul
Hey Roger, I rode my T4 in the snow a couple days ago and had a blast, but now the bearings make some noise. Think I can just regrease and hope for the best, or will I also have to go through this? Thanks for the vid by the way, I'm sure it'll be almost completely identical on the master's little brother
I went through a small flood in Paris today. 10m max of depth up to the pedals at walking pace. I rode then about 10km home, going 60+ kph most of the way and had a very steep hill to finish. The motor heated enough so that the wheel was dry when I arrived and with the centrifuge force it seems the water did not make any ingress. It's a master V2, never had any issues at 3300km riding fairly hard in Paris' bad roads, used it under very heavy rain from time to time with no specific care, except I did replace the thermal pad by some pretty good thermal paste, making it run just ambiant +10°C indicated. Do you think I should be worried about bearings dying after that short excursion in the water, or any other significant damage ? Thanks !
Pedal height means your bearings were getting hit with water. Not that water was being pushed into them. There is a ton of air space in the motor. Put it under water and the air pressure inside is less then outside... that when the water makes its move. You should be good if your bearings were halfway good.
Rather than pounding on bearings, I’ve found a temperature differential works well for mounting them. Heat up the thing receiving the bearing in the oven, and freeze the bearing. Slips right in, and when the temperatures equalize there’s a snug fit. Any reason that wouldn’t work for this kind of thing?
my old method was the bearings in the freezer and the motor covers in the oven. I would also have a torch ready for some extra heat at the last moment. Now I use a hammer. Way easier. I don’t see anything here that could possibly damage the bearings.
Would a bearing press kit like u would use for a car work for this? Opposed to hammering? 😅 just seems like it may be less likely to damage the new bearing. Thanks for the video too! Good stuff!
I don’t feel that I put the bearings in any danger. I made sure to hammer into the motor cover from the outside race and to hammer onto the axle from the inside race. I do have a press in my shop, but I did not think it was necessary.
How did you manage to clean all that rust and gunk out of the motor? Baking Soda/vinegar + toothbrush and elbow grease, or is there a good commercial cleaner you recommend?
I posted a comment with a link to a UA-cam video and it's gone now. Suggesting to check out some UA-cam videos about CorrosionX. Spray on to protect your EUC electronics from dunks. Also some people even get the electronics to work again if you turn it off quick enough and spray this stuff on it afterwards... Also works on bearings. Maybe Dawn can recover her motherboard...?
Can the stator and side covers be put on either side of the rim or does ir have the go a certain forgot to mark mine and a friend said on his sherman that it only goes one way
Thank you for the video! I have a question: Why the RS friction is a good thing? Can only think as waterproofing, about to swap my Smax bearings and I have Z's instead of RS's for the reason of lower friction and better durability + I have extra printed waterproofing on motorcover, thus the bearing can't get any water (thank you @nothing.euc & cer4).
@@TheDwilliams1000 Getting them out of the motor covers on an EX30 is harder because the EX30 does a better job of protecting the bearing.... pretty much the same... just more difficult. Check Dawns video on it if you can find it.
One of the guys said, he just rides through the water. She figured, if he can do it... she missed the part where he said he goes over the little rock bridge.
I love these kind of fix it videos. Never know when I'll need to have these skills in my back pocket!
I was surprised at how easy it was.
@@roghaj I watched this video when I bought my first EUC and it was all so overwhelming... but watching this again now it all looks so easy :D
Never did I think I'd see the day the Master gets its bearings run down. And of all people to do it, there is no one more qualified than Roger 😂
Thanks!

Thanks for another awesome tutorial video! Definitely good information to know…..and knowing is half the battle
You are too nice and an animal to ride with!
Thanks Roger! Changed my old v8 bearings with your help. Can't wait for my lynx, soon here!
I need to change my bearing on my Sherman Max, so this came at the right time. Thanks!
What size bearings does it take... I should post the sizes in here.

She is awesome.
That was the most gripping 30 second intro I've seen in a while...
NO, DAWN! GET IT! GET IT!
I sounded tormented. Sad. Defeated. Dawn seemed fine.
Great, video Roger! Thank you! Are these the same bearings in the EX30?
yes. They are.

This was really fairly easy. I had the touch at the ready just in case. I learned that from Murland.

Thanks for the video mate !! Just wondering... how do you change the bearing inside the motor side ? I cant figure this shit out
Did you remove all the glue around the rim seal? And if so, what can be used to replace that... Can I use a silicone to make it more water resistant?
Yep. Important to get it totally clean. A tiny bit of silicone is all it takes to make the seal 100%.
How did you get the other cover/bearing off? The cutaway when your battery died cut that part out.

Regreasing is a pain in the butt too. Probably good enough though for another few thousand miles. as long as the rust is mostly superficial
Bearing in the freezer and the cover in the oven at 250 degrees for 30 minutes and drop the bearing in
I have used that method in the past. Not as effective as I expected it to be. maybe if you have some dry ice handy, it would be more effective

Hey Roger do you know if the bearings you have linked here will fit the master pro? I assume so since it's using the same C38 motor.
Yes they do
Thank you for the video!

The friction means the RS (Rubber Seal) has a stronger connection to the rest of the bearing. Extra waterproof.
@@roghaj Allright, that is what I was thinking for the reason. Thank you :)
He there Roger. Thanks gor this vidoe. Question. When woyld I have to be concerned about replacing my bearings in the EX30? Around what milage?
Not until they start making funny noises.... even then it might not be necessary. You just wanna swap em before they lock up.
@@roghaj thanks

Never did a bearing swap, hope to never have to, I'll just send it to you lol
You're on my short list of people I'd do that for.... mostly because you're helpless.
@@roghaj That's true. I am surprised the comments have not been stamped with the "Never hammer a bearing" police.
There needs to be a way to do a manual, emergency shut off to immediately disconnect the wheel from the batteries.
There needs to be more common sense when riding an EUC into a lake.
Her main board cover was badly broken and let water flow in freely.
😂 when you surprise the wheel you have to say m***********!!! 😮 It shocks the system 😅
I'll try that next time.... really thought it would work.
atelier plutôt luxueux ;)
My workshop is too big of a mess to actually get any work done inside of.
When you’ve got the A2 on your mind.
I’m waiting for some good reviews on the A2, I’ll buy one if it checks out, need a wet weather ride.
She still won't look before she leaps.
As my understanding goes the 6012-2RS is also good for the ex20s, can somebody confirm?
Yep. Sorry it took so long.
More money than brains i guess
Easy to spot the people that are from out of town.
🤦🏻♀️why ?
That water was to deep for an EUC . Hehe!
One of the guys said, he just rides through the water. She figured, if he can do it... she missed the part where he said he goes over the little rock bridge.
Play stupid games, win stupid prizes.

@@roghaj stupid games = riding into deep water. Stupid prizes = broken EUC. Simple.
