A Series of Unfortunate Events

[TimG]

So I was installing an afr gauge on my 03 escape in my buddy's garage, and he left one of the threaded plugs for the oxygen sensor bung sitting on the head. The clutch cover was open, and when I started the sled, the plug fell down between the clutch and engine. It got caught by a rib on the back of the stationary sheave and snapped off the PTO bearing oiler flush with the case. When I looked closer, I realized that the sheave was also bent.

So what I'm wondering is: Is it possible to machine the sheave and get the inside face true again, and then re-balance the clutch? Or is that just crazy talk? I haven't had a chance to put a dial indicator on it yet, but the warp was visible without spinning the clutch.

I assume that the PTO oiler just threads out and can be replaced without tearing apart the bottom end. Is this the case?

And finally the big one: Is it likely that this episode would've done damage to the crank? The sled was idling when it happened. We heard a snap, and the sled died. We found the plug laying in the bellypan, so it didn't stop the clutch dead, just put enough resistance on it to kill the engine. The bending of the stationary sheave must have taken place when the plug wedged itself between one of the ribs on the back of the sheave and the oiler fitting.

I realize that I'll have to check the crank runout when I pull the clutch, but if it is within spec, would there be any further reason for concern?

Thanks for any and all replies.

I beleive as long as the crank is checked and found to be fine Go with it. The clutch is junk in my book and should not be used.

Also, how is everyone going about mounting the mag base of the dial indicator in order to measure the runout? I understand that it has to be mounted to the engine in order to get an accurate measurement, but haven't been able to find specific info on how exactly to go about mounting it.
