Part of the Yanmar Parts Manuals.
Pull the fuel injection pump off a 4TNV88-XMS and you are one wrong part number away from an engine that sits on the stand for weeks. This Yanmar parts catalog, publication 0CV10-G94800, is how you order right the first time. It covers the standard 4TNV88-XMS and the GEHL-spec variant of the same engine.
Every major assembly gets an exploded diagram with factory part numbers: cylinder block, cylinder head and bonnet, crankshaft and pistons, camshaft and gears, lube oil and cooling water systems, injection pump, injectors, fuel lines, starting motor, generator, gasket set, and short block. When you are alone with a stripped engine and nobody to ask, matching the part in your hand to a numbered diagram beats guessing at a counter.
At 25 pages and under a megabyte, the bookmarked PDF goes wherever the engine is: phone at the bench, or printed and laid out beside the block.
