Lionel 60 Trolley

[rrswede]

Picked up a 60 trolley at a swapmeet. Was not operating. Disassembled it. Armature bottom edges have been rubbing against the frame assembly and bottom of the armature has been rubbing against the reversing slide assembly. There is a nylon bushing that is inset into the frame assembly. Is this bushing part no. 41-27, or is 41-27 a different bushing that holds the armature off the frame assembly and reversing slide assembly?

Thanks, Swede

The 41-27 is the only bushing for the armature. If the armature is rubbing the reversing slide, chances are the bushing is worn and needs replacement. Make sure the reversing slide is flat, and not bowed. If replacing the bushing does not help, there may be an outside chance of the wrong armature being installed in the trolley, or the windings are too low on the armature shaft.

Thank you for the reply, Larry. The reversing slide is flat and the fact that there is only one bushing and it is placed in the frame leads me to believe the armature is not the correct one. My armature shaft does not have a shoulder below the windings and I think I see that feature in the parts illustration in the Greenberg book. Before I buy a new armature, I think I will try to cobble up a spacer that can hold the armature above the frame and slide.

Thanks again,

Swede

The armature bushing is in the frame where it belongs, so that is proper. Be careful with adding spacers; if you raise the armature too high, the worm gear on the armature shaft will not mesh properly with the worm wheel on the axle, and you may chew up the worm wheel.

Thanks for the warning, Larry. I spoke with Jeff Kane at The Train Tender about the availability of a replacement armature and the issues with the current armature. In a package of parts I have on order, he is supplying a thrust collar that hopefully will be the right length and diameter. I will provide feedback to this forum after receiving and installing the collar.

Received my package of parts today. The wall thickness of the thrust collar I ordered was greater than the distance between the armature shaft and its windings and therefore could not act as a "step" in the shaft to hold the windings off the sliding plate and frame. I picked up some thin plastic washers at the hardware store that fit on the shaft and trimmed them so they fit snugly in the area between the shaft and windings and super glued them in place. It took three layers to provide enough height to keep the windings from touching the sliding plate. I added a fourth washer to act as a idler shim, reassembled the trolley and it is operating great.
