Need the factory part numbers for your Yanmar 4TNV88C-STB/STB1 engine? This 48-page parts catalog lays out the complete STB/STB1 through exploded-view figures covering everything from the Cylinder Block and Gear Housing to the Diesel Particulate Filter, ECU, and Electric Parts harness assemblies. Inside: every component identified by Yanmar part number, with cross-references running through the Cylinder Head, Camshaft, Crankshaft and Piston assemblies, Fuel Injection Valve, and the full Gasket Set and Tools section. Cross-referencing the DPF? Soot Filter, Case, and individual Sensor assemblies are each listed as distinct numbered parts. Over on the fuel side, the CR Rail Assy, PLV4 Valve, and injector pipe sets each carry their own line item, so you know exactly what to order. No more guessing part numbers from a blurry parts fiche. PDF opens on any device; bookmarks take you straight to the Cylinder Block, DPF, or fuel system in one tap.
