Manual Torque Specs Wrong

[onenationundergoat]

We did that before the head was torqued, it was just set in place and the bolts were in finger tight. The rod bolts were tightened but not torqued to spec at that point. Then when the first set of rod bolts let us know that something was wrong we checked and used the correct torque on the rest. Then after that torqued the head bolts. My dad has rebuilt engines for thirty years or more, just not diesels, so this is a little bit different but not too much.

I just can't get over how wrong the manual was. I wonder how many other people have had the same (or worse) experience.

Manuals are a good start but yeah they often have odd errors.
Good thing you caught it.
I usually get something nearly assembled and realize I have to tear it back apart, too. Happens all the time.

Agreed, having been a technical publications manual custodian with the Guard, and required to use them for literally *everything*. That being said, they're also *not* "real world." They're god for a start, and a checklist, but when real world experience kicks in, they sometimes go out the window.
