Part of the Yanmar Parts Manuals.
Strip a Yanmar 4TNV98 to the bare block and every washer, O-ring, and seal becomes a part number you will need again. This parts catalog (Yanmar publication 917304) puts factory numbers to all of them for the 4TNV98-ZNMS, 4TNV98T-ZNMS, 4TNV98-ZNTBL, and 4TNV98T-ZNTBL engines, as fitted in the Mustang 2066, 2076, 2086, 2700V, MTL316, and MTL320 and the Gehl 5640E, 6640E, V270, CTL65, and CTL75.
Its 66 pages walk the engine system by system: cylinder block, crankshaft and piston, cylinder head, fuel injection pump, governor, injectors, cooling and lubrication, starting motor, and the ECU and sensors under Electric Parts. Turbocharged variants get their own turbine and oil line sections, and a numerical index closes the book.
When you are alone at the stand with a connecting rod in one hand and no dealer counter to call, this PDF is how you order once and order right. Bought once, it stays with this engine for good.
