Would you reuse this crankshaft sprocket? (EA82)

In my EA82 I'm changing the timing belts and front engine seals for the first time (well, my first time. . .they were changed 60k miles ago by my mechanic). Getting the sprockets off the crankshaft in order to change the crankshaft seal proved difficult. . . and I busted off a bit of the flange on the inner sprocket. See attached photos.

 

Can I please reuse it anyway? I would hate to have to find a replacement, mostly because I really wanted to get the engine put back together this weekend.

 

But, if you think it risky, because maybe the broken spot will wear on the edge of the timing belt in a bad way, then please warn me now. I would appreciate hearing opinions on this.

 

Thanks guys!

It could go either way. I personally would replace it.

I would replace it. But if you do reuse it, at the very least take a small, fine file and smooth the edges of the broken section. The jagged portion of the pulley could damage the belt and lead to premature failure.

File off any rough spots and use it.

 

I've seen many broken crank gears like that and it's not an issue.

IF you can find a better one, go ahead, but if you are stuck with that part, don't be afraid to use it.
