Part of the Yanmar Parts Manuals.
Three rod bearings on the bench and no certainty which undersize you are holding is a bad spot to be in mid-rebuild. Yanmar publication Y00B3752 is the factory parts catalog for the 3TN84L diesel, covering the 3TN84L-RBS, 3TN84L-RBSVM and 3TN84L-RBFVM builds along with the YB271/B and YB listings, and its job is to put a factory part number on every piece you pull off this engine.
Across 49 pages and 14 sections it covers the complete engine, from cylinder block and head through crankshaft, pistons and connecting rods to the lubrication and cooling water systems and thermostat. Every exploded drawing keys each part, gasket, O-ring and oil seal to the number Yanmar assigned it.
You buy it once and it stays yours, a 0.7 MB PDF that opens anywhere and prints cleanly. Keep it beside the engine while it is apart, and order every shell, ring set and seal by its factory number, not a parts counter guess.
