Part of the Yanmar Parts Manuals.
Need the factory part number for your TB28FR engine before the parts counter closes? This 42-page Yanmar TB28FR 3TNE82A-ETBZ Parts Catalog maps every component across the full engine: cylinder block through gasket set, fuel injection pump, governor, starting motor, and generator. Inside: exploded assembly views with individual part numbers for every bolt, seal, bushing, and bearing your engine carries, plus cross-references that confirm exactly what fits. Order the right oil filter (size 80X80L), pull the main bearing undersize (US=0.25), or confirm your fuel filter O-ring spec (P-10A) without touching a phone. No more wrong parts shipped back. Bookmarked by system, so you jump straight to Crankshaft & Piston or Fuel Injection Valve, grab the number, and get back to the counter.
