Replacement spare parts for Wärtsilä 38 and dual-fuel 50DF engines: catalogue coverage for cylinder liners, piston rings, valve seats and guides, exhaust valves, bearings, injection and turbochargers, plus the dual-fuel-specific points to state in an enquiry.

Two related families

The Wärtsilä 38 (380 mm bore) serves propulsion and auxiliary duty, while the Wärtsilä 50DF is the 500 mm-bore dual-fuel workhorse of LNG carriers and gas-burning tonnage (6L to 18V50DF). cballast.com supplies replacement (OEM-equivalent) spare parts for both families — cylinder liners, piston ring sets, valve seats and guides, exhaust valves, main/con-rod/cam bearings, injection components, head gaskets and turbocharger parts — with worldwide dispatch; genuine Wärtsilä parts are quoted on request. For 50DF, gas-mode components (pilot injection, knock sensing) are quoted strictly against OEM part numbers.

How to order — what to include in the enquiry

Engine designation and configuration: the full type from the nameplate, e.g. 6L46, 9L46, 12V46 (in-line L or vee V, and cylinder count).
Component and position: inlet or exhaust side for valves, seats and guides; cylinder number where relevant.
OEM part number from the parts catalogue or the old component, when available — it pins the revision exactly.
Size/condition: standard or oversize/undersize for seats, liners and bearings; new, OEM-equivalent or reconditioned acceptance.
Quantity and required delivery (port, yard or works, with the vessel's agent where applicable).

Quotations are answered within 24 hours with price, availability and lead time; dispatch is worldwide. Certificates (EN 10204 3.1, class certificates) are quoted on request — see the certificate guide.

Frequently asked questions

Where can I buy Wärtsilä 50DF spare parts?: Replacement parts for Wärtsilä 50DF dual-fuel engines — liners, piston rings, turbocharger parts and, against OEM numbers, valve and injection components — can be ordered from cballast.com by quotation, with worldwide dispatch.
What extra information does a 50DF enquiry need?: The operating mode context matters: state the engine variant (e.g. 12V50DF), the OEM part number, and for combustion-side parts whether the engine runs primarily gas or liquid fuel — it affects the correct revision.
Do you cover the Wärtsilä 38?: Yes — liners, rings, valve-train parts, bearings, injection equipment, head gaskets and turbochargers for the W38 family are catalogue items, quoted within 24 hours.
