Part of the Yanmar Parts Manuals.
Mike the crank on a high hour 3TNV88 and the next question is which undersize bearings Yanmar actually makes, and what number to put on the order sheet. This parts catalog answers that for the 3TNV88-N5FA, with exploded figures and factory part numbers for every assembly from cylinder block and crankshaft through the fuel injection pump, injectors, cooling water system, and starting motor.
It is Yanmar publication YOOF9000, an 18 page English catalog covering 3TNV88-N5FA engines manufactured since October 2003. Each illustration keys to a parts list on the following page, so you can put a name and number to the part in your hand without a dealer counter to lean on, then order with the engine model and serial number the way Yanmar asks.
Download the PDF and print the figures you need; pages that can get oily at the bench beat scrolling with dirty hands.
