Both. We supply genuine and OEM-equivalent new parts, and Alang-reconditioned parts measured against the maker's limits before dispatch. We tell you which you are buying — we do not sell reconditioned as new.
What is the difference between the Wartsila X72, X72-B and X72DF?
All three share the 720 mm bore, 3,086 mm stroke and 5-8 cylinder layout of the Generation X two-stroke platform, originally developed by Wartsila and now built under WinGD. The X72 is the original diesel version, the X72-B is the upgraded diesel rating (up to 31,360 kW at 89 rpm, 21 bar MEP), and the X72DF is the dual-fuel LNG-burning variant. Many components interchange across versions, but every part must be confirmed against the engine's build specification and engine number.
Do you supply parts for the dual-fuel X72DF as well as the X72-B?
Yes. We source spares for both the diesel X72-B and the dual-fuel X72DF, including fuel oil pumps, servo oil pumps, injection equipment, exhaust valve spindles and seats, cylinder liners and piston components. Send the engine type plate details and part numbers and we confirm availability of genuine or reconditioned options within 24 hours.
