Part of the Yanmar Parts Manuals.
A scrawled casting number off a stripped block is a poor way to order parts for an engine that is already apart on the stand. This PDF puts the factory part numbers for the Yanmar 4TNE88 small vertical engine in front of you, publication Y00B5943, covering the 4TNE88, 4TNE88-BVA, 4TNE88-EBVA, and 4TNE88-(E)BVA(VIO50-1) variants.
Across 38 pages it works through the engine system by system: cylinder block, gear housing, cylinder head and bonnet, crankshaft and piston, fuel injection pump and pipes, governor, cooling water and lube oil systems, starting motor, and generator, each figure paired with its numbered parts list. Undersize main and thrust metals, gasket kits, and hardware down to individual plugs and studs are itemized.
Every day the engine sits in pieces waiting on a part that came back wrong is a day lost. This catalog gets the order right the first time.
