Part of the Yanmar Parts Manuals.
An engine on the stand goes back together only as fast as the parts arrive, and nothing stalls a Yanmar rebuild like guessing at a part number over the phone while the block sits open on the bench. This catalog settles that. It is Yanmar publication Y00B4202, the factory parts catalog for the 4TN84L-RBA diesel: 39 pages of exploded views and part numbers covering the engine from cylinder block to camshaft.
Seven sections walk the engine group by group: Cylinder Block, Gear Housing, Flywheel Housing and Lub. Oil Sump, Cylinder Head and Bonnet, Suction Manifold and Air Cleaner, Exhaust Manifold and Silencer, and Camshaft and Driving Gear. Every gasket, seal, bearing, and bolt is keyed to its diagram so you order once and order right.
It downloads as a PDF the moment you pay, prints clean for the bench, and it is yours to keep for the life of the engine.
