Help identify this on a 172 engine

[Mistercorn]

We have put a 172 engine on an engine stand for a project we are doing at work, there is something in the side of the engine with a knurled end, can't seem to remove it, it has threads on it but won't screw in. Any ideas what it is:

Crank locking pin. Basically some bell end has tried starting it with that pin still in.

Woops indeed, just got to straighten it and take it out now

Haha. What a mong/

Chop it off in there and slide it out tbh.

We used a hammer and drift to straighten it enough to get it out, going to chop the end of and refit it to plug the hole.

Done any damage to the crank?

Doesn't appear to have done, certainly no bits missing or big marks on it. I bought the engine in an unknown state some time ago, we are fitting it to a gearbox and starter motor to use for testing a power controller so it will just be cranked over on the stand. Fine for what we want.
