Shanghai-based diesel engine parts supplier offering MTU engine bearings for marine, generator, and industrial service. Catalog covers crankshaft main bearings, connecting rod bearings, camshaft bearings, thrust washers, and related bushings, with 57 indexed part numbers across MTU series including 183, 396, 538, 595, 956, 1163, 2000, and 4000. Example references include main-bearing shells 5240334901, 5240335602, and 5410330605, connecting-rod components 5240383710 and 5240382711, and camshaft bearing 5240510110. An engine serial number alone may not describe a previously reground shaft, so shell position, grade markings, and workshop measurements should be included when relevant. Fitment is confirmed against the engine model and serial number, and each quote line names the supply grade. Availability and lead time are confirmed after inquiry. Diesel Part Source is an independent supplier; brand names and part numbers identify buyer requirements.
