Identifing Bolts SPECIAL TORQUE / NEED IN PLACE TO RUN
« on: August 26, 2009, 11:52:07 AM »
Just as Ford assembly line techniques used daubs to indicate handed and "correct for application" parts.....

DYES on special bolts/nuts continued to signal TORQUE TO SPEC or NEED IN PLACE TO RUN.   

As information flowed, on reviesed plant proceedures or after delivery dealer TSB's fixing area issues refered back to confiming placement and torque specs to insure car's didn't have "common problems" in certain areas.

Grounds for the new ECC-IV system were especially important as ANY LOOSE or missing hardware of the terminated circut could create non-run or worse field failure where the problem was "chased" at the dealer level.

This photo from Greg (8T6 SVO) shows his work and proper "BLUE" nuts in place that signaled torque to spec.



In the case of the one on the right - harmonics dictated the addtion of the alternator to manifold stabilizer bracket. One of over 175 changes for the 85.5/86 cars.

This is very intersting, I had no idea why those nuts were blue, and now I know. 

Please keep this info coming.  And who has a list of the 175 changes?
