HX35 turbocharger verified from the exact owned nameplate as assembly 3785477 and model/customer number 3785478(A). Independent exact-number records support Cummins QSB6.7 and 6BTAA applications. The old page asserted Komatsu 6754-81-8090, but authoritative Komatsu and turbo catalogues commonly map that OE number to a different 4037469 assembly; the unsupported direct interchange claim was removed.
