If I remember correctly, RideMan over at Pointbuzz said that most coaster chains are made in Sandusky. I could be totally off, though.

I think that Cedar Fair SHOULD at least buy their brakes from a Sandusky company. I mean, we all know what happens if you try to save a few bucks with the brakes from the "other guys".

Obviously joking, in case it honestly needs saying.

You can see the cotter pins in this picture. We would just remove one at a time, remove the pins, tap in new ones, and repeat. Repeat up to 1,250 times, lol. But a lot of people wouldn't change the chain until absolutely necessary.

And some will have no idea what you just said.

These are some cotter pins:

They are used to keep rods or shafts in place in assemblies. The rod/shaft usually has a hole drilled in it. Sometimes, both "legs" of the pin (the long, straight parts) go through the hole. The legs are then bent so the pin won't come out. Other times, one leg will go through the hole, but the other will go around the outside of the rod/shaft. It's all in how the pin is designed and how the pin will be used. If you have a removable ball hitch on your vehicle, it may use a cotter pin to keep the rod that keeps the removable part of your hitch in place. Here's a diagram I found via Google showing that kind of hitch assembly, where B is the rod being kept in place:

In the picture that Roarbot posted, these are the cotter pins:
