MAN B&W S60MC Main Propulsion Spares

The MAN B&W S60MC is a two-stroke, low-speed crosshead engine with a 600 mm bore, used for main propulsion on bulk carriers, tankers and mid-size container ships. The designation encodes the configuration: the leading number is the cylinder count, S denotes the super-long-stroke variant, 60 the bore in centimetres, and MC the mechanically controlled fuel injection generation. Spare-part demand is dominated by the combustion and running gear renewed at scheduled overhauls — the cylinder liner, piston crown, exhaust valve, fuel injection valve, and the fuel pump plunger and barrel — each carried under a MAN plate number tied to the engine type. The cylinder liner must be ordered against the correct cooling-jacket configuration and cylinder lubrication grooving, because the wrong revision promotes liner scuffing. The piston rod stuffing box relies on a stack of sealing, scraping and oil-return rings held by garter springs to keep crankcase oil clean. Fuel injection moved to slide-type low-NOx valves to meet MARPOL Annex VI, so a replacement valve must match the engine's emission build. This series page lists the curated, plate-anchored S60MC spares that make up a main-engine overhaul, each carrying its identifier so a superintendent can verify fitment before raising an RFQ.
