Lehner motor bearings

That is what I figured. It is hard to tell with the bad rear bearing. I will pick up a pair or new bearings to try out and see how it does.

Update, just ordered some bearings, bringing the total up to 52 bucks so far for this motor, hope it works!

Cool. I'm interested to hear how the reair job works out. What did you do to repair the cracked magnet segment? Not sure how you would get that to hold up to any kind of rpm once its cracked.


I just compared a brand new 1940/8 I have here against a brand new 8XL and they feel very similar as far as how the shaft spins by hand. The Lehner feels smoother. I can actually feel a little roughness in the Feigao. There is no notchy feeling while the Lehner turns.

I tried jb weld, we will see how it does. The segment was the 3rd one in from the pinion end of the shaft. I used jb weld on both sides of the remaining magnets, and on both halves. I assembled the damaged pieces and then rolled the rotor on my table top with some pressure to force the halves back together. The I taped it tightly and let is sit and dry. Hope it holds!

I wonder if Red Loctite would work for something like that?

The stuff is like "steel glue" for bearing races and threads. It also requires 500 degrees farenheit to loosen it's bond.

Not sure about loctite, it requires the absence of air to dry, correct? Or it is not very good at bridging gaps? I have had good luck with the jb weld and the surface was porus so hopefully it will work.

We will see how it goes with the new bearings. I think the new emaxx will get this motor on 5s and we will see how much better it is than the hacker c50.
