[alfa] Re: alfa-digest V9 #914 bolt torque

["George Schweikle" <schweikg@xxxxxxxxxxxxx>]

Digesti,

I'm surprised; The bolt torque thread has yet to address the difference
between tightening torque and breakaway torque. The values are not the same.
IE: loosening a threaded joint that was initially torqued to, say, 50 lb/ft.
will require more than 50 lb/ft. to unscrew the same joint.

Alfa content: I just checked the tail lights on my recently purchased '91
spider, and the white areas on both lenses are the same. Better to be lucky
than good, huh?.
