Part of the Yanmar Parts Manuals.
An injection pump comes off a 4TNV98 trailing a dozen small parts you did not plan to replace, and the exploded view in this Yanmar parts catalog is how you put a part number to every one of them. The same treatment runs through the whole engine: cylinder block, cylinder head and bonnet, crankshaft and piston, camshaft and driving gear, the lubricating oil and cooling water systems, fuel line, starting motor, and generator.
Five variants are covered: 4TNV98-GGE, 4TNV98-NSA, 4TNV98-NSA2, 4TNV98T-GGE, and 4TNV98T-NSA, with separate gear housing and flywheel housing pages where the GGE and NSA builds differ. An Optional Kit chapter adds the engine foot, air cleaner, exhaust manifold, silencer and tail pipe, oil cooler, radiator, and electric parts.
It is a bookmarked 29-page PDF delivered as an instant download, so the diagram you need can be on the bench or at the parts counter in minutes.
