Part of the Yanmar Parts Manuals.
All 40 pages of this Yanmar 3TNV82A-BPTB, BPTB1, and TB228 Parts Catalog (OEM #P-TB228EAB) exist for one purpose: correct part numbers for your TB228 engine, sourced straight from the factory. Exploded-view figures walk through every major assembly, from cylinder block and gear housing to crankshaft and piston, fuel injection pump, governor, nozzle assembly, and the complete gasket set. Parts lists cover engine internals, fuel system, and electrical components including starter motor and alternator, with factory callout numbers you can hand directly to a dealer. Need to ID that seal near the camshaft? The Camshaft and Driving Gear figure names every thrust metal, tappet, idle gear, and push rod by part number. Stop describing parts to a counter guy and hoping for the right one. Bookmarked for fast navigation; jump to any figure or search by keyword.
