Look what happened to my motor
 

I bought a TeknoRC Neu 1515 1Y/F motor on June 3, 2008. This afternoon, I was out in the track running my ST RR when suddenly on the second battery pack, my truck just stopped. I ran to it thinking the MMM ESC gave up on me but I was surprised to see that it wasn't the case. The lights were still on and the ESC was still beeping. When I pickup my truck, I noticed that the tires had some resistance and wasn't free-wheeling when I tried to roll them. I gave it a thorough check and I found out that the motor's rear bearing balls are gone.

Anyway, it sucks being overseas during these times when something breaks. I didn't even attempt to open it up or anything. I just took it out of the truck. I already emailed Tekno so will see what they'll say.

that sucks, hope u get sorted soon.

Ouch, that really sucks. Why not just replace the bearing yourself? Just find out its dimensions, and a new one should just be a press-fit (assuming the endbell screws aren't too tight to undo). It's just a suggestion, but would save a lot of time. An ABEC-3 or above metal-shielded bearing should do the job nicely.

Or you can send it to neu, and if it is less than 1 yr old they will fix it for free and mail it back to you. You have an APO addy, IIRC, so there should not be a problem, only time....which sucks. You could pull the rear endbell off and make sure that the rotor has not damaged the windings.

wow trippy, the bawlz just bailed =X

Dang Lito sometimes you have the worst luck. Betcha glad you have other trucks! Good luck.

Wow that sucks. Did you see any of the balls in the truck or hear them rattling in the can?

The only way anyone will warranty that is if you include all the parts. That means you have to go out and hunt down all the balls.



lol, just kidding! :smile:

Bearing fail. Haha.

His balls have finally dropped... out... ouchy.... :mdr:

Wow, Neil you just took this conversation to far...:rofl:

You guys are hilarious. Yeah, I will have my whole division out in the track today to help me locate my balls :lol::lol:.

Anyway, I was able to contact ImpaktRC and Neu motors this morning since I couldn't sleep after an earthquake struck at 0500 Tuesday morning (an hour ago). The Neu rep told me to send it in and they'll check and repair it as needed. She also told me that they will let me know if it's warranted or not (not warranted for abuse etc). The shaft won't even rotate at all.

I will be down without a Neu motor for at least a month :no::no:. This is one of the things I don't like being stationed overseas. Oh well. I think I will order the Castle combo :intello::whistle:.

Not a fan of having to chase warranty from afar either. Hope it all gets sorted, but this shouldn't happen on such a high end motor!

Thanks. Unfortunately, it happened.

Ouch.
I hate when bearings go bad.
I hope the warranty covers it cause from my experience the windings get damaged from this some times :S
