Trouble with Neu 1521

I was setting the mesh today on my Neu 1521 when I realized the motor can was rotating. Basically the outside of the can with twist a little relative to the front plate. Should I be concerned?

I'm thinking I should......

Probably need to send her in......

It doesn't do this easily, its pretty snug.

If I'm not mistaken, Neu's have screwed on endbells. Simply tighten it down, and you should be fine.

ya they do.

im always worried mine will twist off but it hasnt yet.

I thought the front end bell and the rest of the can were one piece, on the 1515 anyway.

I'm with you Patrick. The front plate of my Neu is one solid piece with the sides of the can. Just the back plate is a separate piece.

o i was thinking an endbell was the end of the motor?

sorry i was wrong then. the rear or my motor screws off.

[jhautz]

Well screw it back on and use a couple drops of blue locktight so it doesnt do it again.

I thought the same as well, with the rear endbell being pressed in.

Lehner endbells are screwed in, though.

Yeah I think the rear is pressed as well, not screwed. I don't think it could be screwed on or off, because the wires wouldn't let it rotate.
Mine came loose a few months ago. My brother noticed it while the motor was out of the car, nothing happened while driving luckily.
I didn't see any threads on the endbell, so I just put some loctite on and pushed it back it. No problems since.

Maybe the 1521's are different? Because what's happening to BashOn's motor sounds pretty strange.

I have a 1521 and the can design looks the same as my 2 1512's. as other have said I believe its one piece and the endbell is pressed on.

I would contact Neu over this; i too think the rear is pressed on, and the front/housing is 1 piece?

I had to dissassemble my Neu 1512 because the bearings were not running smoothly anymore.



I also noticed that the endbell almost came loose on a few runs. The endbell is only pressed on. Which is rather dissapointing for a high class motor. The front bell/can is one piece. Some days ago after i had changed the bearings the endbell came loose for good and the rotor brushed against the stator.




On the other hand i noticed that on my Neu 1515 (Production date 1/4/2008) Neu Motors changed the design somewhat.



The endbell is now glued in and seems to be secured mecanicaly. There are some small marks around the can where the endbell sits. The bearings now are accessible from the outside. So i guess Neu Motors improved the design. The downside (with the new design) is my RC monster cover for the endbell will fall off.

Thanks for sharing othello!

The can of my 1521 is not one peice. Here is a photo of the 1521 and 1527 next to a Lehner 2240. The only thing I don't know if it's screwed or pressed. It might be screwed as mentioned in a post above.

Ah, yes i see, they are different indeed!
