Part of the Yanmar Parts Manuals.
All 46 pages of this Yanmar TB108 2TNE68-ETBA Parts Catalog (OEM #YOOD7640) are built around one job: finding the exact part number before you pull the wrong piece off the shelf. Inside, exploded views walk you through every major assembly on the 2TNE68-ETBA engine — cylinder block, gear housing, flywheel housing and oil sump, cylinder head, intake and exhaust, camshaft, crankshaft and piston assembly, lubrication and cooling systems, fuel injection pump, governor, injection valve, fuel filter, starting motor, generator, and the complete tool and gasket set. Cross-reference numbers are called out directly on each diagram so you can match what's in your hand to what's on the page. Reference values embedded in the catalog include the 0.25mm main bearing undersize, crankpin bearing undersize, and piston oversize specs — the numbers you need before you order. Your machine is down; stop guessing part numbers from memory. Bookmarked by system, searchable by keyword — grab the right number and get the order in.
