Replacing Motor Bearings

[@electricmotorrewinder5368]

Great video, I'm here in Brazil, working with electric motors rewinding and exchanging bearings general maintenance. Twenty years, I love my work.

[@TrophyJoe]

Thanks for a very informative video. The audio was weak, but I was able to deal. I am restoring a 50 yo table saw. Motor and saw arbor need bearings. Your video encouraged me to do it myself.

[@grantw.whitwam9948]

Good video, I had very low volume. I have motors where the bearings were getting old, I have just drilled a very small hole in the side of the bearing and filled it with oil using a syringe, seem to work well for a long time. Not like getting new bearings, but very cheap and easy. Thanks.

Good work

[@antigen4]

ack!!! you didn't get metal filings in the bearing?

[@gaetagro]

Nice job! I love your little home-made press

[@17Triumph675R]

Put rotor in freezer for hour and put bearing in oven for 15min at 175 degrees slides on much easier

[@mtjosvold]

Well shot and informative. Very helpful, thanks!

[@jahnkaplank8626]

FYI bearing pullers are like $30 for a set of 3 (different length legs) at Harbor Freight so it's pretty cheap.

Great Job, Excellent Video, you covered all the particulars that I needed. Well Done. Thank You, I love KZbin, as it is my "go to" helper when I need it; and it comes through with "flying colors".

[@victorvodkafish]

Thanks! a bearing in my aircon's fan seized. typical...middle of summer.

[@tchew25]

Great video, but too quiet for my speakers.

[@onjofilms]

This is why I love KZbins.

Thanks for making this. I learned a lot.

[@shopdoc]

great job! appreciate the explanation.

very nice thanks for the help!

Excellent video for me. I pulled my (extremely similar) baldor apart. It has ntn 6205c3 and 6206c3 bearings that are sealed on both sides. The motor frame has grease fittings on each end but no purge points. Anyway, i want to replace the bearings yet those part numbers come up as open bearings, not sealed. Id like sealed bearings just like you installed and then would probably remove the grease fittings permanently. Im new at dealing with bearings, any advice you can give me?

[@BSpotBuilds]

I agree with you and would replace the open with sealed. Seems like your on the right track.

[@zaidhussain5206]

Thank you so much for sharing this video, what is the commercial name for the mechanical too you used to extract the old bearings ?

[@shawn8770]

Zaid Hussain bearing puller

[@zaidhussain5206]

Thank you.

[@bonniekabau3870]

Good try, but using a bearing heater allows you not to damage the bearing in the process.

[@BSpotBuilds]

Your right you could use a bearing heater, but how many people own one? I have seen more than a few bearings destroyed by overheating the seal or cooking the grease out of them using ad hock methods. Motor bearing fit isn't that tight and by pressing on the inner race the bearing wont be damaged.

[@toddl5424]

How'd you get the bearing out of the bell end?

[@BSpotBuilds]

It's normally a slip fit and comes out easily.

[@toddl5424]

@@BSpotBuilds well I've got a motor that when I pulled the rotor out, the rear bearing came off the shaft and stayed in the frame of the motor. Definitely seems pressed in. I am destroying it to get it out, which is no big deal but it is a lot of work

[@BSpotBuilds]

@@toddl5424 You can drill a couple holes in the bell end so that you can get a punch on the outer race and tap it out. Best method I know of for a sized bearing in the end.

[@toddl5424]

@@BSpotBuilds thanks, that probably would have been quicker than what I did. I took a dremel tool with a metal cutoff disc and went at the bearing. It took a couple hours. That is some damn hardened metal on those bearings

[@1marktran]

Where did you order the bearings from sir?

[@BSpotBuilds]

Ebay

[@zaidhussain5206]

I guess you also can find them at any local hardware store

[@antigen4]

NOT SO EASY - i'm just finishing up my unisaw motor rebuild and got into several snags - couldn't drive the larger bearing onto the shaft all the way so i had to spend the entire day trying to find a shop with a bearing press - amazingly most auto shops DO NOT have these - at least not in los angeles - so i had to go to a specialist ... took a long time to argue them into doing it since they seemed to think it was a liability working on 'electrical' parts ... then after getting it all reassembled even though i was trying to avoid this - stator ended up rubbing on the capacitor wires - UGH - back to square one!! tear down and rebulid again

[@tomk3732]

Unless its some large engine get or make on lathe little bearing tube that only catches the inner recess and hammer on the other end. You don't really need a large press. I never actually pressed the bearings onto the motor shaft.

[@antigen4]

yes i did that and banged the HELL out of it trying to get it on but it wouldn't work - i suspect i deformed the end of the shaft originally when trying to get the bearing OFF - all in all it took me two weeks to 'rebuild' the motor - hope i havent' made it worse than before (!) - would have been much more efficient spending $700 on a whole new motor

The sound isn't the best, the closed captions work.
