Part of the Yanmar Parts Manuals.
All 40 pages of this Yanmar 4TNV98-STB1, TB180FR Parts Catalog are built for one purpose: finding the exact part number before you place that order. Inside, you get exploded-view diagrams for every major engine assembly, from the cylinder block and gear housing to the fuel injection pump, governor, and starting motor. Each diagram pairs illustrated component breakaways with factory part numbers and cross-references, so you can identify a crankshaft thrust bearing or nozzle holder assembly without guessing at descriptions. Match your alternator to the 12V-55A factory spec, or confirm your crankshaft V-pulley by its 130/145 mm diameter before you pull the trigger on a replacement. Wrong parts shipped are a week wasted. Bookmarked and keyword-searchable, this PDF lets you jump straight to Fuel Line or Gasket Set sections and land on the right diagram in seconds.
