MTU 4000 Series Engine Parts

The MTU 4000 series represents the top tier of MTU's high-speed diesel engine range, with power outputs from 1,500 kW to over 4,300 kW in 12V, 16V, and 20V configurations. These engines are found in the world's most demanding applications: fast naval vessels, superyachts, offshore supply vessels, mission-critical data center generators, and heavy-haul locomotives.

Parts for the 4000 series are engineered to extreme tolerances. Cylinder liners, pistons, and bearings are size-graded components where an incorrect grade selection — even by one step — can cause premature failure. Every part number in this catalog is verified against MTU's electronic parts catalog for your specific engine serial number before quotation. We supply both OEM and OEM-alternative options, with remanufactured components available for high-value assemblies like injectors and turbochargers.

High-demand 4000 series parts include cylinder liners (5240113410), cylinder head gaskets (5240161580), injectors (EX52407500064), main bearings (5240334901), conrod bearings (5240383710), and turbocharger turbine wheels (5110804420). These are components where lead time can directly impact vessel availability or generator uptime. We stock common grades and can expedite special orders.

For major overhauls, we recommend sending a complete parts list with engine serial numbers. We verify each line item, flag any superseded part numbers, and quote shipping from Shanghai via express courier, air freight, or sea freight depending on urgency and part dimensions.
