Part of the Yanmar Operator Manuals.
Air trapped in the fuel lines will keep a TNV diesel cranking without firing, and the priming procedure in the Before You Operate section is where to start before you condemn the injection pump. That section, along with the troubleshooting chart and its fault list for electronically controlled engines, does the diagnostic work while your genset, pump, or bare engine on the stand sits idle and the day slips away.
Yanmar publication 0ATNV-EN0019 is the 166 page operator manual for 30 TNV industrial engine models, from the two cylinder 2TNV70 through the 3TNV70, 3TNV76, 3TNV82A, 3TNV84, 3TNV88, 4TNV84, 4TNV88, 4TNV94L, 4TNV98, and 4TNV106 families, turbocharged variants included.
Inside are diesel fuel and oil specifications, starting and cold start procedure, the full periodic maintenance schedule, long term storage steps, and a Specifications section listing bore and stroke, displacement, and normal oil pressure for each model, the numbers you check before the engine goes back to work running clean.
