Important note:
The Advance marine gearbox GWC42.45 Q can not be held responsible for torsional problems arising from the drive system. We therefore recommend that a calculation and adjustment for the vibrational data of the ship’s entire drive system should be performed including the torsional compatibility of the gearbox.
