Hi All,

In tearing down the 322 AC Hudson, I found that one of the rear wheel drivers (the drivers with gears) was loose on the axel.  After pulling the wheels, I found that the axel had been damaged on one site (rotted, or who knows what). 

Is it possible to replace the axel with the gear?  Or is this get a new body?

Just about any Flyer steamer is repairable,  that's the beauty of those locos.  It all depends on how much work you want to do.  As other members of your club probably told you, if you replace a wheel or axle, make sure it's quartered correctly.  Good luck, and let us know how it went!



Some suggestions.  1) Inspect the hub of the driver that came loose -- running loose on the axle can damage the inside wall of the hole in the hub -- you might want to replace the hub as well as the axle.  2) Inspect the condition of both 3-pc drivers while you have them off the axle -- is everything snug -- rim on insulator, insulator on hub, hub on axle?  Many are coming loose and/or apart.  In many cases I would disassemble, clean, replace parts as needed, glue, and reassemble drivers (best done with wheel cups) even if conditions weren't really bad yet just to give them some assurance of a second (50 year?) lease on life before reinstalling.  3) Check the quartering of all three set of drivers (best done with a quartering jig) -- are they all the same?  At this point in their life, with who knows how many people having "worked" on an engine by now, you never know what you might find.  I found many on the same engine quartered differently. Some quartered at 87.5 degrees, others at 90 degrees (both are factory settings), and others at who knows what (probably previously "eye-ball" quartered).  Note: some engines were forward-quartered (6 o'clock on the right, 9 o'clock on the left) others rearward-quartered.  4) In any case, make sure all of the drivers are quartered the same way.  Uniform quartering compared to mixed quartering can make a big difference to final outcome and performance.  PS I used a forward-quartering 90-degree jig.

Hi Jerry & David,

I can take the stuff apart (see photo under York purchases) and Roger from NPS has all the quartering devices and repair devices.  Mike will do the electronics, my one hand shakes from an injury and I struggle with tight tolerance soldering.

So far, I haven't found a replacement axle, but I am sure I can come up with one.

Hi Dave,

Thanks, but I did get the parts before Thanksgiving.  The engine is with NPS being updated with DCC.

Dave, I got Reading Passenger car decals from you, now I will need some engine, tender and hopper car decals. 

Can you do this?  It will be a little later in the year.


Well the question was answered at the Great American Hobby show, the 322 cleaned, remotored and upgraded to DCC performed very well.  I couldn't get the pin off off from the lobster claw so that I could replace it with a knuckle coupler, but I'll do that this week.

I have to repaint it, renumber/redecal it with authentic markings, then it will be a worthy part of the rooster.
