Water pump bolt sheared

1985 ford f150 efi 302 engine. While removing the water pump mount bolts, the bolt securing the alternator belt tensioning bracket sheared flush with the water pump housing. I have taken a chisel and hammer to it but have not been able to seperate the pump from the timing cover housing. It seems as though the bolt is seized to the pump housing. Do I shoot me or the truck? Any ideas?

Yes, I re-eyeballed it, all bolts removed. After borrowing a oxy-acetylene rig I was able to cut away enough of the water pump and offending bolt and perform a successful, but complicated, extraction of the pump.

CAUTION
WORKING WITH OPEN FLAMES IN AREAS WITH COMBUSTIBLE FUMES AND FLAMMABLE FLUIDS IS
DANGEROUS
The offending bolt protrudes from the timing cover housing approximately 1 1/2 inches. The space between the diameter of the bolt and the circumference of the hole is about.080 and is packed with rust.

Presently, I'm chipping away at the rust a with 1/16" welding rod and pentatrating oil, thru the timing cover housing, with the intent of providing a galley for the pentratranting oil to reach the block and the offending bolt theards.

With a set of vise-gripes on the offending bolt, torsion is apparent in both directionns but with no give on the the bolt.

As I'm doggedly chipping away, the weather is 100% humidiity, 36 degress [F], and I'm thinking that there has to be a more effective pentranting oil than what I'm using!

Open for opinions.

Jack,

Apperciate your response
