Lehner 1950 end cap help!!!
 

I need an end cap for a Lehner 1950. The part the screws onto the motor and has screw holes for mounting it to the transmision plate. I think its called an end cap. Any ways I think the threads where stripped or almost gone before I bought it. Does any of you have one I can buy? Or does anyone know a fix I can do for it? 3\4 of the threads are gone on the cap. The threads on the inside of the motor are fine. I can't get it tight again. It was one heck of a jump though.:yipi: I landed it but the threads just could not hold the weight of the motor.

Thanks!!!

Check out this thread, I had the same problem!

Edit:
I see now that I might have missunderstood you....

That endbell cap would be great. I will order one after I get my endbell fixed.

OK. I am not getting a big response here. Hyperus had a thought. Does any one have a blown Lehner Motor lying around you don't need anymore? I would buy it from you. Let me know please. The truck looks good sitting on my bench but I bet it drives better.:lol:

Would the RC-M motor clamp do you any good? It's meant to hold the Feigao's together so it should work with the LMT 19xx as well.

No it won't. The back of the Lehner motors have the weld marks that would short the motor out if the clamp was attached. Thanks for the idea though.:yipi:

It would work. Use washers under the bolt heads instead of the cross bar.

The RCM clamp still uses the motor screw holes to hold the motor on the motor mount so if the screw holes are stripped it wount help.

Could you remove the end cap and re-tap the threads? It seems like it would work...

I'd have to go with cemetery gates, pop the end off and tap them to 4mm, any chance that might work? I know some of the larger can motors already run 4mm screws, why not yours too.

Thinking crazy, I've seen very small helicoils work on a huge number of things. If they'll hold nitro funny car heads on I'd have to believe that they'll hold a brushless motor in place??

Personally, I wouldn't go with the helicoils on a motor. I'm gonna agree with Cemetary. I would definately pull the motor apart and tap the out to 4mm.

The heat sink won't work unless I don't understand how it goes on. Do you not put one end of the heat sink between the motor and the motor mount? You just use longer screws? If I am wrong let me know. I am just looking at the picture in the RCM store. That would hold the end cap it self on. The end cap motor mount screw holes are fine. The end cap it self screws into the motor body. Those are the threads that are stripped. Not the mount screws hole threads. I might see if there is enough metal left to make new threads but it looked like the metal was gone so no chance of using a die to make new threads.

Maybe I am not explaining things right. As an example look up at What’s_nitro’s avatar picture. This is an LMT motor. The end were the motor shaft comes out of the motor is a purple end cap. On the purple end cap in this picture is drilled 6 motor mount screw holes. My motor has 8 motor mount screw holes. All 8 of these screw holes are fine. It’s the purple end cap that is broken. The purple end cap screws itself into the black motor body. That’s where the threads are located that are stripped. I can pull that purple end cap off and mount it up fine but the motor will not screw onto the end cap. Because I can’t get the motor screwed onto the end cap I can’t run the truck. I hope this clears up any confusion on my part. Thanks What’s_nitro for your picture!!!:yipi:

Hey, no problem! Glad I could help...will you buy me one of those??

You could try JB weld on whatever is left of your endcap threads and use the motor clamp along with a spacer of some kind to prevent shorting. Maybe replace the aluminum clamping bar with some 1/4" polycarbonate and also use a zip-tie around the circumference of the motor/motor clamp.

Have you thought about ordering a new endcap direct from LMT? I think they call them "front bearing shields" on the website.

Sorry, if I buy one its going into something of mine. I have been thinking about a water cooled system on an E-Revo. Thinking is the key. I have used JB weld for stuff before. Thats a last ditch option. It gets everywhere. Or maybe thats becuase of my fat fingers.:neutral: You did bring up a good idea. Using the heat sink as a stabilizer in some way. Maybe turning it over. It should help hold the motor better upside down. I might have to design a heat sink that utilizes that concept. I liked the idea of Mike’s Lehner end cap cover. Maybe I can build a cover like Mikes but add a heat sink running on the top and the bottom. Then I could get the best of all the components and support the motor at the same time. This is becoming more of a project then I was intending. :oops: I thought about going directly to LMT but I did that before. When I was looking for a motor I contacted them. They want to do business but through western union. I would not have any guarantee. Plus shipping for one would cost more than the cap. (I think that is)
