The yoke seems to have shrunk by a millimeter or two, and I cannot pry it over the metal stanchion. The reason to remove it is to shave down the inner forward and aft faces of the interior of the yoke, as it fits too tightly and is very stiff on its axis of rotation.
Is there a way to get this yoke off the stanchion? The metal part seems brittle; a tiny piece flew off when a screw driver was used to gently pry, perhaps it is zinc.
I'm guessing I may have to cut one side of the yoke in half to free it up, and then, when reassembling have the shell hold it in one horizontal piece, but wanted to check here, first.

Looking at all the cracks in the truck, it appears that the truck is crumbling with zinc pest. That usually expands it, so I'd say that the yoke has not shrunk so much as the truck has grown. If you can get the two apart, it might be easier to file down the truck to fit than to shave material off the slippery plastic of the yoke. In any event, it'll be interesting to see if the truck lasts much longer or if it'll finish crumbling.

Chops, I've never personally seen a Tyco Wheelset with a case of zinc pest as bad as what this one does. Considering it looks to be a Tyco Aussie Diesel, I'd say it may have something to do with the climate over the pond.
Here's the best advice I have for you. In about a week, you'll be receiving an item from me. The box will be perfectly sized for a Tyco F9. Within five minutes, I went into my parts supply and obtained these items:

That is everything required to rebuild that rear truck into perfect operating condition. If you pay shipping to me plus 10 bucks for parts, labor, and return shipping, I'll completely replace that truck with original Tyco Parts (and I'll even try to get the 15 sticker on the new truck). In addition, for this price I will also clean the shell, replace/grind the drive wheels to improve electrical contact, and I will lubricate the motor if it needs it. You'll essentially be getting a refurbished engine. You decide.

A generous offer, and I appreciate your skill. Would it work for you if I pay for the parts and shipping? Easier than handrails, for sure, and a five minute assembly and solder job, that way I don't risk mail loss/damage. It was well packed, but was knocked around hard enough to pop the power truck out and snap off the rear coupler. Fortunately, no shell damage, though they did their level best.
