With maintenance on multi-rotors how often do you replace your bearings .?and where do you buy the replacement parts e clips bearing washers? Thanks, I have 2814 motors made by aerial media pros, they said they don't sell internal motor parts. I wish I would have known that before starting down that road with that CO., in the future I will only buy motors from a CO, that Carries parts for there motors,
Bearings from Quadrocopter or Boca Bearings. Bearing replacement tool from Bart at www.multirotorforums.com. Clips/washers from McMaster-Carr. The tool Bart sells comes with 20 clips. Only replace on condition. Sound will change. Perhaps after a severe crash. There aren't any other user replaceable parts.
Thanks so much, is there a way to find out the size of the washer and clip, I bought Bart's tool and after changing the bearings I have a slight up down movement , is that ok ?
Don't be afraid to swap out your bearings, and inspect/clean your motors after 60-80 hours of use. These are radial bearings, employed on a perpendicular load axis, without the support of a thrust bearing; they wear significantly faster than when used in their purposed application. There's no reason to ditch a bearing if it works well, either. Just note it in your service logs and continue the usage cycle.
Sounds great, what about up and down movement ? Very slight, how do you figure the exact thickness of the washer and e clip? , are there company's out there that Cary replacement parts for the motors they sell, like a rebuild kit, for the next set of motors that will be a big factor on which ones I go with.
Jason, I'f you've got "up and down" movement in the bearings, change them; be sure it's not from vertical shaft play, which can be remedied by shimming- though I'm not sure of your motors specs. They look identical to the T-motor version: http://www.rctigermotor.com/html/2013/Professional_0912/46.html If this is the case, then you can get spares from t-motor, or use specs to source your own. If specs can't be acquired from the motor manufacturer, or just pop them out carefully, and take them to a local bearing supplier(look for "Automation Equipment Suppliers"), in your area. Don't bother with fancy ceramic bearings; a basic ABEC rated bearing for high RPM will do the trick. When you find a source for them, but enough for a few changes, bulk buys often yield significant discounts. For installing bearings, get a cheap manual press from Harbour Freight, along with an appropriately sized bearing removal/press tool. It's a simple process that will give you huge piece of mind. Good luck, PT
No need for any lube. After taking off the bearings, I always clean the motors magnets with WD40. It takes off the dust and small particles out of the motor. After cleaning, I put the new bearings in.
