Lionel ES44AC help?

Remove the trucks and see if the little tees on the motors are tight on the motor shafts on the bottom. I had that happen on the front motor on a few of these . If that is it you have to replace the motor . It seems to happen on the front motor more  .You can glue the "T"s back on but it won't last. The reason why this haappens is the white grease gets sticky in the trucks and the wheels don't roll well and those pressed Ts on the motor shafts can't take the stress. 

JOJO,

  I took off truck and checked the tees on both motors.  You were right the front tee was loose and came off.  I will try to glue with Gorilla glue and see what happens.  If not are these motors available from Lionel?  Thanks for the response.

JOJO,

  I went to Lionel parts site and ordered the front motor with sensor.  Anything else do I need to know?  Thanks again for the reply.

Make sure that front truck wheels roll freely . If not it will do it again. If there not rolling good you have to get some bearing oil on those bearings .it's the 2 bearings that hold the shaft on the top of the truck. 4 screws removes the shaft and the 2 bearings .I also had good results putting some oil down there and taking a coreless drill and chucking it to the shaft that drives the wheels and freeing them up with a little oil..My guess is why this happens is white grease gets in those bearings freezes them up. It be nice if those bearings where buyable from lionel ..After I have done this I have never had a issiue with it again.  My advice to anyone that buys any of the diecast es44s is to before you run it make sure it rolls freely . I bought a nib cp rail and learned the hard way .. 

Thanks JOJO.  I had glued the tees to the shaft and it is holding so far.  I have the motors coming from Lionel and will run this until it goes again then will replace the motor.  I will clean up gears and oil real good as you stated.  Thanks for the help.

Your welcome glad to help ..
