Bad Day, Very Bad day

Looks like the end that goes into the pump is broken off. The pictures are fuzzy, but there should be a couple inches (IIRC) of hex part that goes into the pump. Also, the little bit that it looks like you have left, looks twisted. It should be straight.

Old Kimmer comes through again! Probably the sharpest guy on this board IMO.

That's what I thought, the bottom of the shaft is supposed to be similar to a hex head bolt and have flat sides and not be grooved as this shaft is. I am going to order another pump and shaft (a hardened one if I can get one) and tear it open and see what transpires. I do not think I did any major damage to the engine. I shut it down pretty quickly.
