Picked up a Gilbert Hudson, which in addition to being missing lead truck and chug piston, has two frozen main axles.
Any thoughts on freeing it up? It's looking like I might have to pull the drivers and use a drift to knock the axles out, or something like that.

I'd say let it sit in WD-40 or Kroil overnight and see if it loosens up a bit.

Agreed. I had one with the same problem, and it took lots of solvent and repeated applications of fresh oil to free up the bearings. Make sure whatever you use won't damage the plastic whitewalls or wheel centers, depending on which version you have.

Try rubbing alcohol first. I had a 0-6-0, same problem. 1 hour soak in alcohol and a snug twist and it was loose! The alcohol helps by removing old lubricants. If no luck there, use PB Blaster. That's great stuff and can be had in a gallon jug. If PB is used or WD or what ever, don;t let it sit too long, as Nelson said, it'll attack and the plastic will get soft and gummy!

The drivers will actually move on the axles - looks like they must have plastic centers.
I was thinking if I had to I could pull the drivers off, drive the axles out, and then drill and install some brass tubing to act as a bearing.
.. and if anyone has a parts engine shoot me a private message.

The engine chassis is zamac zinc, right? I think another member here had to knock out the axles, drill the axle holes slightly, and re-install the axles. Probably expansion of the zinc by corrosion causing the tightness. I'd go ahead and remove the drivers, and then soak the metal parts in alcohol as one guy suggested. Either way, total disassembly is probably required to fix it correctly.

You'll need a puller and a quartering tool.

| It occurred to me that if I scribe the ends of the axles across the driver center, I could avoid the need to quarter them simply by matching up the scribed lines later.

Just like I learned in auto tech class, timing is everything.

Those are known as witness marks, but if some of the drivers have already twisted on the axles, then marks aren't going to get them back in quarter.
Give it a soak first to see if the axles will loosen. It worked on mine, and they were frozen solid. I was fortunate that the wheel centers never lost their grip on the axles. No need to install brass sleeves, either; it will work fine without them.

That was me with a Gilbert Funit a couple years ago, I think the thread is still on here. And make no mistake, I tried the solvent suggestions, overnight patience, gentle encouragement, all of it... got all the lubricant residue out clean, but the axles were fully seized in the bores, so it really did come down to necessary brute force in the end... man, that was a beast of a job for HO! I'm still amazed I got away with it.
