I’m not sure about the chassis, @pennytrains, any ideas on where to find parts? I’m asking you since I know you have a wide variety of Lionel locomotives (and your one of the few people I know that has a large Lionel collection)
Seems to me you could cut liners from Delrin or HDPE, or use Teflon sheet (or the material we used for bushings in radio-transmitter dummy-load switching)
Im finding that the way the axles are located on this chassis is through solid plates with axle holes. These plates are punched in 4 places on the perimeter to lock them in the cutouts in the chassis.
I have not seen this before. Though I don’t have a lot of experience with older loinel trains, the only bushings ive seen are the brass round ones.
If i could find replacement plates, it would help salvage this old train!
It appears what you have is a later 675, from 1952. This version was built nearly identical to the 2035, but with the aluminum motor parts changed to steel and the magnetraction magnets eliminated.
The middle axle bearings are part no. 2035-162 for the plain wheel side, and 2035-165 for the geared wheel side. The bearing pieces for the front and rear axles are 2055-109 for the plain wheel side, and 2055-110 for the geared wheel side.
My usual parts source, The Train Tender (Jeff Kane) only has the 2035-162 listed. I suspect it would be very difficult to track down replacements for all the bearing parts.
Ideally, I would try to find perhaps some small metal tubing with an inside diameter that matched the axles, and then drill out the bearings to accept the outside diameter of this pipe with a press fit. Then cut the pipe to length to make bushings for the worn out bearings.
I thought you meant hub liners, between the inside faces of the wheels and the side plate.
Bushings in the plates, as bearings for the axles, can be made up if wear there is the concern. The procedure is similar for bushing clocks with worn arbor holes. One concern is that the holes in the mechanism have to be essentially line-bored on the axis of the original wheel axle, so simple drilling or even a drill press may not give accurate-enough alignment. I think I’d recommend a vertical mill (or drill press with an appropriate long end mill) which cuts the end and sides together.
I think if you make the bushings separate and not a continuous tube, you should install them with a mandrel or shaft to keep them aligned
