Well said PRR 4800. Actually if the pilot ever does brake or disintegrate the plastic one is a perfect replacement so even then all is not lost.

 The only issue with that is that the pilots go for quite a bit of money due to demand nowadays. Seriously, some of the prices they sell for are insane.

Anyway, I went online today and found a forum post about someone suffering a zinc pest problem with a Bowser 4-6-0. For some reason, this started making me think about my Mantua Pacific, especially when I found this photo I took a while back of the base of the tender.
Basically what I'm trying to ask is; does my Pacific have zinc pest according to the above photo?

Is there something specific in the photo you're referring to? It's not a closeup, but if there were mild zinc rot you'd find hairline cracks, distortion of the parts, and screw holes that didn't line up anymore. The only reason I mentioned it was because of the frame I have, but the wheel centers on mine swelled and distorted but never let go of the axles. If anything they're on tighter. I consider it a pretty rare example for Mantua.
Your problem was probably a combination of age, use, insufficient knurling on the axle, etc.

The thing I was pointing to is right on the tender base around the slot where the screw and the wire goes in. It kinda looks corroded or something although I'm not sure.

Nope, it just looks like paint rubs or a rough casting. A little white corrosion on diecast is also normal with age & moisture. There's no corrosion in zinc rot, the casting just reacts and explodes from inside.
Here's an example in an auction photo for an old Rivarossi Lionel C-Liner. The truck frame has expanded and bowed downward because of the brass bottom cover, and a chunk where the sideframe mounted fell out. Every example of these I've seen has swelled enough so that the screw holes in the bottom plate don't line up exactly; sometimes they need filing. Notice how it's riddled with cracks.

Huh, thanks for the info, NickelPlate. I just didn't want to have to deal with yet another issue after it gets back.Also, it was just a little bit of paranoia or something like that.

It looks more like someone took a sledgehammer and hit it really hard a couple of times.I would hate to see someone doing that to my model railroad equipment.

The magnificent old girl has returned from the shops at last and she runs almost like silk. No replacements needed; just the wheel needed to be adjusted and a new wire. Here she is now.

Aw, darn. They got rid of the vintage cloth wire. 
I'm sure you're glad to have her back, though. You won't find a loco that's more reliable and easier to work on than these guys.
Btw, if you want another example of zinc rot I found one of the worst cases I've ever seen. This was a Rivarossi Consolidation. The tender floor and lead truck on most of these fell apart, but this one's turning to powder.

Since you've seen to have forgotten, the original wire was the one that started the problem to begin with. It broke off to the point where it was useless. And about the consolidation; gosh, that looks absolutely horrible. It's actually kinda sad to see it in such sad and hopeless shape.What is that orange thing in the tender, though? Is that more zinc rot or something?

Just because the lug broke off doesn't make it unusable, unless it's become brittle or too short to reach. I think the old cloth wiring is cool, so I try to keep things original if possible.
That's a block of foam in the tender that was there to absorb motor noise. It's no doubt hardened and turning to dust.

The part that goes on the tender also broke off. I have pictures somewhere of it I believe so I'll try to post them when I find them.

Nope, can't find them.Oh, and I meant the little ring thing that went on the tender broke off too. Too bad we threw it out months ago.
