Question Torque Specs

I am having a hard time trying to find a couple of tourque specs for the engine assembly. It's an 83 Sporty Ironhead

Also I want to know what section I need to look in to find the specs in the service manual.

Here is a pic of two of the torques I need. I would call them flywheel nut and clutch hub nut, just a guess though.

ALSO, I can't find the torque specs for all of the bolts that hold the two engine halves together.

ANY HELP WOULD BE GREATLY APPRECIATED

150 ft lbs on each nut. Then be sure to bend the tab of the clutch hub washer down against the flat of the nut.

Tighten the crank case bolts in a cross pattern to 10 ft lbs each.
Then using the same cross pattern, do a final torque of 15 to 19 ft lbs for each bolt.
You will not find this in the service manual.
(Figures taken from the 2003 Dyna Factory Service Manual)

Here is a list of torque values given in the Dyna Factory Manual for different size (and different strength) bolts.
Copy it and pin it up somewhere.......................
