SL2017-654 MAN B&W Crankshaft Torsional Damper

Service experience has proven that the intermediate inspection of the torsional vibration damper on the crankshaft of our mentioned GenSets can be omitted without compromising a reliable engine operation.
This applies to both for new engines and to engines in service.

Consequently, we have deleted the intermediate inspection from our planned maintenance programme (510-04.00), thus saving related dismantling and inspection work.

The lifetime of the vibration damper is in the range of 48,000 to 54,000 running hours, after which it must be replaced.
