Part of the Yanmar Parts Manuals.
All 48 pages of this Yanmar 4TNV98T-ZXWTB Parts Catalog (OEM #P-TB285EAC) map every component on this turbocharged diesel engine, from cylinder block to the Electronic Control Unit. Inside, you get exploded-view figures for every system: crankshaft and piston assemblies, fuel injection pump and governor, turbocharger, cooling water system, starting motor, alternator, and the complete gasket set. Each figure carries factory part numbers so you can cross-reference the exact component before you call the dealer. Part dimensions are listed right alongside: the flywheel housing calls for an M10x35 bolt, the gear housing O-ring is spec'd P-7.0, and the cylinder head takes a PT1/4 plug thread. No more describing parts to the counter and hoping someone guesses right. Bookmarked by system and searchable by keyword; grab your tablet, walk up to the engine, and find the exact part number before you even pick up the phone.
