Frequently Asked Questions

What MAN B&W S50ME-C9 spare parts do you supply?
Genuine, OEM-equivalent and Alang-reconditioned parts for the S50ME-C9, including cylinder liner, cylinder cover / head, piston crown, piston skirt, piston rod, piston rings (compression and scraper). Send the part number for anything not listed.
Which S50ME-C9 variants do you cover?
We supply parts across the S50ME-C9 family, including 5S50ME-C9, 6S50ME-C9, 7S50ME-C9, 8S50ME-C9, 9S50ME-C9, S50ME-C9.5, S50ME-C9.6, S50ME-C9.7, S50ME-C9.7-GI, S50ME-C9.7-HPSCR. Designations differ by build series — send the nameplate designation and we match parts to your exact variant.
What is the delivery time for S50ME-C9 parts?
Stock items dispatch the same or next working day from Bhavnagar. Emergency orders ship in 24–48 hours to any major port. Sourced items depend on the yard — we confirm a real date before you commit.
Are your S50ME-C9 parts genuine or reconditioned?
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 S50ME-C9.5, S50ME-C9.6 and S50ME-C9.7?
They are mark versions of the same 500 mm bore, 2,214 mm stroke ME-C9 platform. MAN introduced the C9.6 and C9.7 with improved SFOC over earlier marks. Most wear parts are shared across marks, but always quote the exact mark version and engine builder from the nameplate with your enquiry so we match the correct part variant.
Do you cover the gas-injection S50ME-C9.7-GI version?
Yes. The S50ME-C9.7-GI shares the base ME-C9.7 running gear — liners, pistons, rings, bearings, exhaust valves — with additional gas-injection-specific components. Send the engine nameplate details and we will confirm availability for both fuel-oil and GI-specific items.
