I think bearings should be between .002 and .004 for clearance. Sleeves should extend above the deck .002-.004 also.
You can do a google search for torque specs for about any size or grade of bolt.

I'm not taking sides here but, My well used and oil covered for-real Allis Chalmers shop manual has the same INFO in it that Greg posted. 
I think I have used up all of my IT shop manuals for fire starting after they send me down the wrong path to many times. The funny thing about burning them up; is they didn't even burn that good for what I payed for them!

Thanks, I appreciate the info. Can you tell me what the ring gap is supposed to be?

Typical ring gap is .001 to .0015 per inch of cylinder diameter. This is the specification for a new ring. I don't know what the maximum allowable gap would be.
