Postwar lionel armature comes out, need advice.

The cover plate popped off without warning? Is it simply you're missing some screws? These are simple motors, and can usually be easily repaired. To call it 'dead' is very premature.

As CJ said, this is an easy fix.  There are two screws that hold the motor backplate in place.  There are also two brushes (copper colored cylinders) these fit into holes in the backplate and have springs to hold them against the armature.  Put the brushes in the backplate and screw the backplate to the motor frame.  You might and a little grease to that worm gear.

I took the cover plate off to clean the contact portion of the armature. The whole armature is out of where it was seated now.

The worm gear at the other end of the armature will not screw into the drive gear.

There is no lateral moveable space on the motor housing which apparently is part of the truck? Not familiar with this chassis .

Can this be taken apart with killing the gear alignment ? There appear to be brands not screws that hold this trck together.

Any ideas?

Should be able to screw back into position....

 hi CJ and DANR.

I am familiar with the maintenance, screws and brushes part as you described.

The armature will not seat into the housing and make contact with the gear on the axle. No wiggle room.  photo attatched. 

Thanks for your responses.

Just let the gear turn as you lower the armature back into position. The tip of the armature shaft goes in that cylindrical hole in the black plastic plate at the bottom.
There is no need to break down the motor assembly, and nothing to be gained.

They are not designed to come apart any further.

There was a screw that fell into the magnatised well housing!!!

Armature now placed back  without issue, brushes in, screws on, runs well? I just did not see well enough in the well!

all good. Thanks for your support.

leroof.

Well done. Keeping these beautiful toys running, and for me, reviving the basket cases, is half the fun.
