Lionel NW-2 6220 or 622 dead

[Anonymous]

I have a Lionel 6220 which will not run! I've done all the normal motor maint. and even replace the E unit. At the brush plates there voltage in two postions of the E unit and in the third there is no voltage ie nuetral. Does anyone have any trouble shooting idea's that I may have over looked. Yes I applied ground the
external housing of the motor.

Loren,

Welcome to the CTT forum!

1. You did the right thing to see if there is voltage at the brush plates in sync with the e-unit.

2. You may need to remove the brush plate from the top of the motor to examine the brushes themselves. Are they contacting the commutator? You might be able to see without removing the top of the motor by looking into the opening in the motor that faces the rear of the loco with the body shell off. You can usually see the brushes and the shaft where it goes into the top bearing.

3. If the brushes are contacting the commutator, you then examine the commutator itself. Is it extremely dirty? Clean it with some TV tuner/Contact spray and then burni***he copper with a pencil eraser. Use a toothpick to clean any gunk from the divisions between the 3 commutator plates.

4. You did not mention if the loco buzzes when the voltage is applied. This could indicate that the gearing and wheels are bound up. On my 623, I can easily roll the wheels with my fingers and spin the motor assembly.

If the link does not take you there directly, go to http://pictures.olsenstoy.com/ and go to the Library and then Enter the Library to get to the old drawings.

Good luck,

Hi Lionel1948, Just thought I'd say welcome, [#welcome] to the forum here. Don't forget the Coffee Pot & Sunday Photo Fun, if you get time ! Thanks, John

You might look into the possibility that the field winding is open. If you don't have an ohmmeter, try briefly connecting a little voltage between the frame and the field terminal, to see if you can make a spark.

If it is open and the connections at each end are good, you are faced with rewinding it. However, a close inspection might reveal mechanical damage to the outside layers if you are lucky. In that case, you might be able to repair it in place--I have a couple of times.
