Yanmar Operator Manuals
The owner book for a ViO17 on a rental yard trailer and the one for a 3GM30 in a sailboat’s engine room sit side by side here. Excavator owners get books like the ViO17 through ViO57 series and the C12R, C30R, and C50R carrier manual. Boat owners get the 1GM10 through 3HM35 and JH4 series books. Industrial and farm owners get the 2TNE68 through 4TNE84T engine book and the EF494T tractor book.
Fluid capacities and the service schedule for a 3GM30 or an EF494T are here. Valve clearances, injection timing, and hydraulic pressures for the same engines are in Yanmar Repair Manuals.
