NEU motor broken, how to measure, and locktite in motor screws?

I agree - the motor has a problem if it overheats quickly. It could be a broken winding or demagnetized rotor. As far as the screws go - the Muggy mount can accept m3 or m4 motor mount screws(current version). We include the aluminum bushings and screws for m3, which is preferred(aluminum bushing gets great "traction" on the aluminum mount). If the bushings are omitted, however, the m3 screws will mar the mount and get little "bite" due to the small surface area.

Hello,

Thanks for the reactions!
The rotor is still very strong, but it is from another old NEU ( also a 1521, but a different Kv, does that matter )
The rotor was in a 1577Kv 1521, and now in a 1050 Kv 1521.
I am using a 1717, so I think that is M4?
But I meant the kind of screw, cap heads, or button heads or something else?
It sucks being from Holland, shipping and expensive parts is to expensive for a student..
I think I get another 1717 for in My LST to ( I used the NEU in the LST and the 1717 in the Muggy )
Does someone have a 1717 wich is for sale for not a lot of money?



Thanks!

Ruud
