Part of the Yanmar Parts Manuals.
An engine apart on the stand with a worn crank leaves you one question: standard or 0.25 undersize. This Yanmar TNV series parts catalog answers it in part numbers, listing the 0.25 undersize main metal and 0.25 oversize piston rings alongside the standard fits, so the machine shop's grind and your parts order agree before anything goes back together.
It covers the 3TNV70-GGE, 3TNV70-ASA and 3TNV70-HGE, plus the 3TNV76-GGE, 3TNV76-CSA and 3TNV76-HGE, across 31 pages of exploded views: cylinder block, gear housing, camshaft, crankshaft and piston, lubrication and cooling, fuel injection pump and governor, injectors, fuel line, starting motor, generator, and the complete gasket set.
A guessed part number wastes as much money as a guessed torque figure, just more slowly. Download the PDF, jump by bookmark to the system you have in pieces, and order the right piece the first time.
