UPDATE:  fiancé moved in right after July 4th, so just got back to TR3.  Got the fan, fan belt, water pump and pulley off.  Removed the bolts from the crankshaft pulley.

Next step is suppose to be to remove the dog bolt.
Questions now are: 1) it looks like a 1 1/8 inch socket to fit over dog bolt...is that correct?
2) as the bolt is turned counterclockwise, any advice on how to keep the whole thing from Turning? 3) the fan belt pulley is loose. It looks like it is in 2pieces (front and back piece)is that right? Does the dog bolt and the arm in front of fan belt pulley need to come off to get to everything now?

All the wisdom of the list is appreciated...thank you all.
