Part of the Yanmar Parts Manuals.
Lay the injection pump from a 3TN63L-UNH2 on the bench and you are looking at a plunger with barrel, a delivery valve with seat, and a rack, each carrying its own Yanmar part number and each easy to order wrong from memory. This is Yanmar publication 0CD10-G43800, the factory parts catalog for the 3TN63L-UNH2 industrial diesel, spec Y00D4380: 18 pages of exploded views and numbered parts lists straight from the OEM.
Every group gets its own page: cylinder block, cylinder head, crankshaft and piston, camshaft and drive gear, lubrication and cooling water systems, injection pump, governor, injectors, fuel pipes, engine stop device, starting motor, generator, and the optional gasket set. Order a main bearing or ring set from memory and you pay twice: once for the wrong part, again for the second teardown. Look the number up here instead, then print the page you need and let it get dirty on the bench.
