Revised Flywheel Bolts And Torque Specifications On 
                            Audi 2.0L (3A), 2.2L (3B), 2.3L (7A, NG) Engines

Audi has revised the flywheel bolts on 1988-91 2.0L (3A), 2.2L (3B), 2.3L (7A, NG) engines used in the Audi 80, 90, 90 Coupe and 200.  

The revised bolt, Part # N 902 061 03, features a shoulder and uses the torque-to-yield method to achieve its final clamping load.  Seat the bolts using a torque of 22 lbs.ft., then turn each bolt an additional 1/4 turn, or 90o.  Because of their
special locking compound coating, the revised flywheel bolts may only be used once.

The former bolt, Part # N 902 061 01, which was torqued to 74 lbs.ft., did not have a shoulder and is no longer being serviced.
