[tech]: update--moving timing

[abatzis2@hotmail.com (Michael Abatzis)]

i managed to get off all of my belts and pulleys to check out why my 
timing's been moving.  i turned the crank to get at something better, and 
found that the crank bolt was loose.  Hmm… couldn't get the last crank 
pulley (with the timing mark on it) off.  so i took the crank bolt off, and 
removed the pulley and crank sprocket together.  findings:
1)	there was no woodruff key to be found anywhere, or even remnants of one 
(i circled where i thought it should be).  this is looking at the inside of 
the crank sprocket;

that even though i circled something on the last pic, the inside is actually 
quite smooth).
2)	the slot in the crank didn't look chewed up or anything, but i don't know 
what it should look like (circle where slot is, conveniently covered by 
belt);

3)	the crank sprocket and pulley were one piece, like they were welded 
together or something; www.learnlink.emory.edu/~mabatzi/beerfest 016.jpg . 
this, iirc, should not be the case.
what i'm thinking is that someone screwed with this before, welded the 
pulley and sprocket together, and used the crank bolt to keep everything 
from slipping (which if it was tightened enough would work).  the forces 
eventually loosened the bolt, and there was no key to keep things in place. 
make sense? so a couple of questions:
1)	can i use the sprocket/pulley from my 1.8 shortblock?
2)	how do i get the crank bolt off? the shortblock is just sitting there—how 
do i keep the crank from turning? anyone done this? i have an air wrench 
coming thurs, but i'd like to get it done before then if possible...

hopefully this is all that's wrong, and i can slap it all together sometime 
this week without taking apart the engine as i feared…
any other thoughts/suggestions?
