Two-Stroke Engine Parts — Common Questions
Answers to specific questions our clients ask about sourcing two-stroke marine engine parts.
Do you stock cylinder liners for MAN B&W K98MC-C and S90MC-C engines?
+
Yes. We maintain ready stock of cylinder liners for the full MAN B&W MC and MC-C series, including K80MC-C, K90MC-C, K98MC-C, S70MC-C, S80MC-C, and S90MC-C. All liners are dimensionally calibrated and undergo MPI testing. Bore sizes and running condition are documented and available upon inquiry.
Can I get a matched set of piston crowns and rings for a Sulzer RTA84C engine?
+
Yes. We supply reconditioned piston crowns for Sulzer RTA84 and RTA84C engines, individually or as a matched set across all cylinder units. Each piston crown is decarbonized, MPI tested for ring groove cracks, and Hydraulic Pressure Tested for cooling bore integrity. Chrome-plated piston ring sets are also available new from stock.
What is the lead time to source a connecting rod bearing shell for a MAN B&W K80MC engine?
+
For crosshead-type bearing shells (top end and bottom end) for MAN B&W K80MC, we typically have used shells with good metal condition in stock. New OEM shells can be sourced on a 2-4 week lead time. We always recommend replacing bearing shells new at overhaul; reconditioned ones are suitable for emergency use only.
Do you supply reconditioned exhaust valve cages and spindles for Mitsubishi UEC75 engines?
+
Yes. Exhaust valve cages and spindles for Mitsubishi UEC60, UEC75, and UEC85 two-stroke engines are available. Spindles are precision-ground on a valve grinding machine and dye-penetrant tested. Cage seats are re-cut to match spindle contact angles. Hydraulic lapping compound tests are used to verify seat tightness before supply.
Is it possible to source a complete fuel pump assembly for a Sulzer RND90M engine from Alang?
+
Yes, complete fuel pump assemblies (plunger, barrel, delivery valve, and housing) for Sulzer RND series engines are among the components we regularly recover from vessels at Alang. Each fuel pump is bench-tested for fuel delivery pressure and plunger-to-barrel clearance before dispatch.
