Neu motor design changes?? - 04.21.2008, 03:52 PM

I just got my 1515/2Y back from Neu for repair and noticed several design changes from teh original motor I got ~8mos ago. First of all the shaft now has a flat spot for a set screw. The end bell now seems held on by small hex screws (rather than glued or whatever before) and lastly the front bearing seems larger.

My magnet seperated from the shaft, and a front bearing failure was also listed. So basicially its a brand new motor.

Has anyone else seen these changes? I'm curious to see if the F bearing is indeed bigger. I remem that being one of the changes CC employed to the Neu for the MMM, and I wonder if that will be std now given how many Neus are going into cars these days. Has anyone tried to remove the endbell? Hopefully its easy in case the bearing fails again I can more easily replace it.

Kudos to Neu tho. Sent the motor in and it was back within two weeks. Only had to pay for the shipping there and fill out a simple form on their site. :) :)

Man, you HAVE been gone for a couple of weeks! lol. Yeah, there was a thread about this a bit ago. Don't remember anything about a better/different bearing, but the screwed endplate and flat spot was discussed. Keep in mind that the presence of those screws will require mods done to the end cover Mike sells...

Would you guys think Neu might do the changes for free if one already owns 3 of their motors?

You could call, but I would say no... unless you have a problem with those motors...

@Finnster
I noticed design changes too. I have an older 1512 and a newer 1515. My 1515 still has the same bearings as my 1512. But they are accessible from the outside. And the endbell is better secured (not the version with screws though).

The same happened to my Neu 1515/2Y this weekend:
While i was driving my truggy this sunday the magnet of my Neu 1515/2Y did also separate from the shaft. I now can slide the shaft in and out with my fingers and the front bearing now also rotates inside the can. This happened because a small stone blocked the rear middle cvd and the shock on the motor was obviously too much. I really was dissapointed. Never expected this to happen to a Neu. This is the second failure of a Neu motor in offroad use. The Neu 1512 had its endbell loosened which resulted in the rotor brushing against the stator. I could repair it myself though.

The interesting part is that you only payed for shipping. What happened with/to your motor exactly? Did you call them on the phone before sending it in or did you only fill out the form on their website? Do you have the exact url where i can find this form?

Guess i will get in touch with the european distributor of Neu before shipping it to the US.

Thanks.

Sounds like a 7XL story but with customer service.

There is a pdf to print out, its on their website under support. Basically you fill it out and send in w/ the motor. I did call @ 1st to see if I needed an RMA# or reciept or anything. I was just told just the completed form was needed. :)

IDK what happened. I got the setup in the fall (Oct.-ish) and its been mostly sitting. I took it out last month to play, and all of a sudden the motor was stuttering. PLayed w/ it and the failed rotor was obvious.

Curious thing was the shaft seemed to have been slipping forward early on. It kept chewing up my slipper pads on the Revo. I thought maybe the pinion was getting loose &/or bc of a broken motor mount. I guess not quite right from the factory.

So how much does it cost if you want Neu to do this to the old Neu's?

IDK. A busted motor? OTOH, I asked if it was possible to get the motor rewound (thought about a hotter motor.)


The rep I talked to thought they could exchange the motor for %50 of a new one. Ehh, no thanks, I'll just gear up a bit.

If they made the motor better in any way they should honor a free upgrade. Specially now that the prices have gone down a bit.
