Neu bearings
 

I was cleaning my brushless St-RR when I was checking the gear mesh I noticed there was some play in the rotor shaft, I could move the pinion up and down slightly. I was concerned so I removed the motor (Neu 1515/1Y) And sure enough there was some play in the bearing. I clamped the motor in a vise and hooked up a dial indicator (attached to the shaft) to try and get some kind of measurement. I think it has about .06" worth of play. Is this something to be concerned with? I purchased this motor new in March 2008. I also have a Neu 1512 in my buggy, and it has a little play as well but not near as much as the 1515. I have an e-mail out to Neu support asking about this, but I wanted to know if anyone on this forum has any comments or info to share.

.06 worth of play is too much in my opinion. I would not accept anything more than .005 and that may be stretching it. I am definitely curious as to what neu's opinion is on this.

I have neu motors, too. Although mine is still fine, I am curious about the replacement.
Is it possible to replace the bearing by ourselves or we have to send it back ?
Anyone ever replace the bearing of neu?

What size are the bearings?
And what is the best type of bearing to use in the motors?

I would just send it in. They really stand behind their motors and may fix it for free. The endbell of my 1515 1.5d/f started to come off, so I sent it in...with no receipt. Not only did they fix it, they put new bearings in too. It was like a New Neu! All this for free. They even paid the return shipping.

I sent one in for new bearings once. About 2 weeks total shipping incl. Fairly cheap and it was like a new motor when I got it back.

Don't even mess with it IMO. Just call Neu and send it in.

Hey thanks for the feedback and I agree with all of you that I should just send it back and let the pro's check it out. Steve Neu did reply and basically said the same thing. It's just that I hate to be without my motor for 2 weeks. Also, pretty quick response from Steve.

Hello,
It might be a good idea to send it in for a check-up. .05 is a little too much.

But for the peace of mind that 2wks buys, I think it'll be well worth it.

It really impresses me to encounter a business that cares about their customers!
