I'm not even going to ask....

 

i will, how the f did you do that?

 

i'd be willing to bet sticking a pipe or something through the sprocket to keep it from turning while trying to loosen the bolt to get the sprocket off...
???
that also explains "Oops?" instead of "WTF?" for a thread title.

 

^ hahaha, good call

 

I'd put my money on trying to pry it off the end of the camshaft

 

maybe it's a prototype sprocket for a dual cam 22r head...
... and they had to take that part out so the other sprocket would have clearance?

 

did you just need an excuse to upgrade?

There must be more story to this than OOPS!

 

Not the camshaft bolt. That's not all that tight. I'm guessing the crank bolt.

 

Yeah....you can see in one of the larger holes a chunk that was gouged out from sticking....probably....a screwdriver in there.

 

yep... the hole at about 2 o'clock. definite deformation there.
wanna place bets on whether Phillips or flat screw driver or socket extension?

 

1 dollar says it was a flat head.

 

the screwdriver or the person that used it?

j/k rusche.

 

ouch.. lol.

 

Improper use of tools can lead to broken tools, parts, or injury. Or any combination of those three.

 

dont force it....get a bigger hammer

 

that was a great set-up for an MC Hammer pic, but I resist....

*edit---
I fail:

 

It wasnt me who broke it, it came out of an engine I bought on craigslist for $50.
I'm gonna have to go with the screwdriver theory though, getting it off the camshaft. Definite "WTF?!" moment when I pulled the valve cover though.

 

wow you bought that engine from a real winner.
