Pressing in a bearing by pushing on the inner race with a bolt and nut can ruin the bearing. You can put the bearings in the freezer and cool them and they usually will slip right in. Otherwise you need to use something like small sockets to put the force on the outer races when pressing in the bearings. Thanks for the video. As you say, new bearings can really help.
How can a bearing go wrong? What happens to them? Can you please advice me if I should change the ball bearings on a propdrive 42-58 500kv 60w engine after it hit the ground. The engine still works fine, shaft straight, lots of power, everything ok but when I hand spin the prop some slight noises are heard. Now I know they must be from the ball bearings but at firs by the way it sounded I thought that the mouving part is touching something. You can barely hear it.. I think it's the front bearing, should I change it? The rear one I couldn't find on my local store or hk. What could happen if I don't change it? And what can it cause by going bad? Thank you!
I don't see any washer under the C-clip on this one. My Shus have a small bronze washer between the bearing and the clip. Two of my rotors popped off in a crash yesterday, and I'm trying to find info on what size washers they use, as I don't want to buy an entire bell just to get the spare washers and clips. Anyone have any idea what size these washers are?
The $9.99 fixes four motors though, not just the one. With two spare bearings left over. So it's more like $2 per motor. For $2, I'm definitely not just buying a new motor and robbing myself of the fun of fixing something that's broken.
Your hex driver is the perfect tool to seat the bearings!! Put the driver through the bearing and tap on the driver lightly! Or if yours doesn’t fit just right take the old bearing and put it on the driver first so that you have something that’s literally the exact same size and then tap away! My drivers have a plastic end cap so it’s nice and dampened when tapping! Hope it helps :D
Josh Withrow awesome I’m really happy I could help!! I found this out totally on accident while sitting there frustrated as hell trying to seat my bearings in those exact same motors!!
Hi Guys! thank all of your for your input (read EVERY comment!) - I'm all the way in South Africa and the bearings here cost $3.57 each so I'm going to have to resort to ordering them from Amazing and pay for shipping. Any other advice while I'm on Amazon? Are the ones Josh used the best option? Really appreciate your help!
They only made it a few weeks and a couple of crashes before they started grinding. As it turns out, the bearings are the most science part(s) of the motor, so when replacing bearings you really need to buy the good ones.
There is a secret little tool for those c-clips that can get em on and off in seconds. Go to your local pharmacy and look for those type of tweezers that OPEN WHEN YOU SQUEEZE the handle. I cant remember what they are called but they are essentially reversed tweezers. The tips fit perfectly into the little "c's" on the clips and allows you to just squeeze and lift them off and then do the same to seat them. I kept getting sand in my motors at a certain spot and once i discovered those tweezers i could take off and clean out every bell and put them back on in under half an hour...
@@JoshWithrow No problem man, spread it round! Lol one of the things keeping me from running certain motors were those damn clips but its as easy as taking out a set screw now... all thanks goes to my girl friends makeup bag hahaha
You may have already figured this out, but you need to move the printed paper out of the sceen. It will make the autofocus work a lot better. A sticker or printed bandaid can help too.
What I found is that the clips were not staying on if I included the brass washer underneath. But if I remove the brass washer they stayed on fine. I haven't lost one since doing that.
maybe they are a bit thicker than the original and with the washer they sit too high and can't enter the groove in the shaft. The groove in the shaft is a little smaller than the shaft diameter, but if 3mm works for you it's great! I'm in the process of changing the bearings on 1106 size motors with 1.5mm shaft, wish me luck haha
i use the bolt method ...but use a washer the same size as the bearing for a damage free sink!..but i use the original bearings till they crap out first! because their not that bad really!..
How do you know that a bearing went bad, what hapens to them? Can you please advice me if I should change the ball bearings on a propdrive 42-58 500kv 60w engine after it hit the ground. The engine still works fine, shaft straight, lots of power, everything ok but when I hand spin the prop some slight noises are heard. Now I know they must be from the ball bearings but at firs by the way it sounded I thought that the mouving part is touching something. You can barely hear it.. I think it's the front bearing, should I change it? The rear one I couldn't find on my local store or hk. What could happen if I don't change it and what can it cause by going bad? Thank you!
So, the new bearings were better than the originals, but by 100 packs started really breaking down again. I guess to get good bearing life you have to actually buy the good bearings.
Josh Withrow good bearings are hard to get right now. Probably get some NSK when they are in stock at the bulk supplier. I like the eclip idea. Thanks man
I've moved onto, and settled on only using, Sumax Innovations. If you buy a half assed motor, then buy expensive bearings, you've now spent more money than just buying good motors lol.
I do! Those clips are called e-clips and you need them in the 3mm size. tTe problem I've had with those as they don't see on the shaft properly they do click into place but they don't stay in place and I think that's because there's not enough of a Groove to keep them there. I still have a little more experimenting to do before I share with you guys, but I found both the c-clip / Jesus clip style clips as well as the eclipse and I want to share some of what's been going on with these motors with you guys.
Josh Withrow I have both the cobras and the dys, I'll check if the clip on the DYS fits the Cobra one. I do have the c clip tool, it's really easy for me to remove. It's only a couple bucks but totally worth it!
