Thomas;
I understand the
niceties of torque sequence; but it would seem that is all out the window
when the engine has been run about 6 hours, many cycles to full power, and a
dozen or more temperature cycles to 200-210 F; all with the two large bolts
loose. As far as I know nothing untoward has happened, but how can I
be sure?
Al
Al,
didn't intend to step on your engineering prowess, you are
waaaay ahead of me in that department!
Just was pointing out what (little) I remember from
Engineering school.
In your case, the only acceptable (...for me) way to go is, to
remove the redrive, loosen all bolts and tighten them according to the
manual.
In a (race)car you might get away with an
"emergency"-thighten-up, but it is your a** up in the
air!!
Your engine was running well for a while now, so a complete
tear-down seems excessive, but I believe wrong ( or none ...)
torque-settings will show their ugly face in the long run. Better make sure
everything is right and tight.
I understand that it is definitely NOT your fault, but your
engine builders - you might believe these guys put a little more extra care
into assembling an AC engine - manual on the job, step by step list to hook
off items, after-assembly check list, etc.
In your case torques on bolts don't mean anything at this
time. "Niceties of torque sequence" applies IF DONE (right) - obviously on
your engine no one cared enough to check torque, let alone
sequence.
Doesn't shine to well on a supposedly reputable
shop....
Enough ranting, back lurking!
