Part of the Yanmar Parts Manuals.
Strip the injection pump on a 3TNE68 and you are holding a plunger and barrel that only match one exact part number, not the near miss a cross-reference chart will sell you. Guess wrong and you pay twice: once for the part, again for the second teardown. This Yanmar parts catalog (publication 0CR10-G45101) breaks that pump, the governor, the injectors, and the fuel filter into exploded views keyed to OEM part numbers.
Coverage runs through the whole engine: cylinder block, cylinder head, crankshaft and pistons, camshaft and gears, lubricating oil and cooling water systems, radiator, generator, panel, starting motor, and the full gasket set. It applies to the 3TNE68-SA, 3TNE68-G1A, 3TNE68-G2A, 3TNE68C-SA, 3TNE68C-G1A, and 3TNE68-62A.
At 28 pages it is a small, bookmarked PDF that lives on whatever phone or laptop is nearest the engine, on a stand or in service, so the numbers are there before the parts order goes in.
