This list brings together the 11 part numbers our catalog records for 20V 4000 B24F, 20V 4000 B24S, 20V 4000 B44S and 7 more. The engines share most of their service parts, so they are listed on one page; the exact fitment of each part is still confirmed against the engine serial number before quotation.

Engine Models Covered
The list covers 20V versions of the Series 4000 for diesel generator set. Each model code below is read from left to right: cylinder count and arrangement, series, then the application and build codes. The MTU engine series guide explains the naming systems in full.

Parts by System
Across 5 systems, gaskets and seals (55%) and sensors and electrical (18%) are the two largest; the other 3 systems hold 1 number each. Each section below is the complete set we can quote for this model family — the engine serial number still decides which variant of a given number is fitted.
Gaskets and Seals
Gaskets and Seals — 6 of the 11 numbers listed here (55%). 1 of them carry an earlier number in our catalog history, which is why a parts list written against an older manual can still match this page. Representative references: X00008172 (Grommet), X52404200043 (Gasket for Cylinder Head), X52499100022 (Gasket). The full gaskets and seals list for Series 4000 is on the MTU 4000 gaskets and seals catalog page .
