Wartsila’s User Group Forums 34 SG Wartsila Engine Exhaust Support and Bellows Failure

    We recently experienced a failure of Support 202 359 and Bellows 200 081 in the exhaust piping to the wastegate. This occurred at only 1784 running hours.  About 25 hours earlier we found all four bolts sheared off at the B10 multi-duct to exhaust flange.  We never expected to have such failures so early in the life of these units.  Is this typical of the 20V34SG engine?

    Thanks for any feedback,

    This is a constant issue for us. Wartsila has a few different designs, but none of them eliminate the problem.
