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


Agree with Jeremy. We are performing inspections at least every 1000 hours and tend to notice the failures in CA pressure and wastegate response. The newest design from Wartsila goes to a single (larger) bellows that should be able to account for greater misalignment and thermal expansion but takes quite a bit of modification and is not a cheep fix. ~$1.3M for parts and installation. Can forward proposal if desired.
