Page 135 last paragraph.."rotate the crankshaft"...how?

After tightening all the fasteners......"rotate the crankshaft"......What's the method here? Attach the pulley again?

Thanks.

That's the easiest way. You don't need to final torque it, just use a rachet

omly guessing my book is downstairs, but I am guessing you have the rods in the case and the case halves together, if so, be aware the rods will hit the case and jamb up the crank, you need to fiddle with the rods to be sure they don't hang up.

It is the rod bolt nuts that catch on the inside of the case.

OK. So I did that.....and the crank rotates freely, no-binding with my large torque wrench between 35-39 ft/lbs. (after tightening the pulley nut for rotation, when I go in the direction of the pulley nut "lefty-loosey", the nut will eventually loosen)

Does this sound right? Or do I need to change the torque on the case bolts to loosen or tighten the rotation?

Thanks for the advice.

you should be able to rotate the crank by hand (on the pulley). 39ft/lb seems a lot to me.

Yes, I see! I went around and checked all the torque values with another torque wrench, and found the oil cooler dome nuts to be a bit tight. Just a small difference, and now I can turn the crank pulley by hand, by one hand in fact. (It's firm though).

Thanks!

Firm is okay. It takes abit to overcome the "stickiness" of the assembly lube. I've found that it generally takes around 20 ft/lbs if done about right.

After going crazy..... it stayed around 20 ft/lbs, but I could not move it by hand! Then after a very sllight change in the torque of cooler domes it finally came down to where I can move the pulley by hand thankfully.

(After compaining about passing through the homemade rod and chain supports, the case sat right down, fast enough and solid that I can't recall having a chance to see everything.....I know the pump seals went well, but it went so quick I wished I could have observed the #8 o-ring better.....but I was above the halves, ...but at least the #8 bearing looks good)

Hmm, you can't check torque of a fastener if it's not turning - they will always read higher when they are static and not being tightened.

Hmm, my explanation is not clear?

I'm referring to amt. of resistance at the pulley. (Not the book explanations)

i.e. "freely" being highly subjective to this green-horn.
