Locator pin on timing cog missing
When putting my engine back together after the timing belt, I forgot to put metal ring on the crank pullley. The bolts worked themselves pretty loose leading to some crank pulley wobble.
In the loosening process, the pin which locates the crank pulley managed to work itself loose and fly off.
Apart from the now missing pin, is there anything I need to look for? The engine has only run for about half an hour from the time I reinstalled everything to discovering the problem and virtually all of which has been at idle.
Should I just use the whole timing cog from the spare engine, or can I get away with just replacing the pin?
Anything else I need to worry about or check for as a result of this nonsense?

That's not a pin, it's a woodruff key. Check for damaged keyways in the pulley and the crank. Since both are critical to timing, they will have to be replaced if damaged. The 1.6 long nose is not immune to the pulley bolt coming loose. I had to replace my crank because of it.

I'm talking about the pin on the face of the cog, it ensures that the crank pulley can't be bolted to the cog incorrectly.
Definitely a pin and not a woodruff key.

Can the pin be replaced/removed? I got the impression the times I saw it that it was built in. I don't think anything bad will happen without it. It doesn't hold anything, only aligns the outer pulleys to the inner timing gear/cog/pulley. Once the bolts are in, its clearly aligned and can't go anywhere (of course bolt it up as if it were still there). For sure use that metal ring though. I ran mine without it for a few miles and never felt comfortable. Not sure that anything would happen without it either, but its probably there for a reason. If that pin does come out, and you can get it out, it would be good to replace it.

Isn't it there for the timing mark location on the outer pulley? Either way, with or without it, it should be fine. As long as its bolted on the right way you won't miss it. I wouldn't know where to look for a replacement, unless you are taking it from the spare engine.

A good hardware should have hardened pins, just cut it to length and maybe loctite it. You're right about the timing mark, I forgot about that, balancing is the only thing I could think of.
