Yanmar TB219 3TNV70-NTB Common Problems This Manual Covers
Yanmar TB219 3TNV70-NTB fuel injection nozzle part number unclear, unsure which nozzle assembly fits serial number p. 27
Open the Fuel Injection Valve exploded view on page 27. Locate the Valveassy and Nozzle entries in the parts list. Cross-reference the Shimset (Adjusting) part number listed there to confirm you have the complete injection valve assembly. Verify the Injection Pipeassy part number on the same page matches your engine's configuration before ordering.
Manual Section: Fuel Injection ValveCan't identify the correct fuel filter assembly and strainer element part numbers for a full filter service kit p. 29
Check the Fuel Filter parts list on page 29. The Strainerassy and Element entries are listed separately from the Separatorassy (Water). Note both the Fuelfeed Pump part number and the Strainer part number. If ordering a complete service kit, source the assemblies together, including the strainer element, water separator, and feed pump strainer.
Manual Section: Fuel FilterNeed glow plug or starter motor component part numbers after cold-start failure, unsure which sub-assembly to order p. 31
Turn to the Starting Motor parts list on page 31. The Starter assembly breaks down into Armatureassy, Clutchassy, and Housingassy sub-components; order only the failed sub-assembly rather than the full starter. Fasteners on page 31 use spring washer size 12. Cross-reference the Index to confirm part number currency before placing the order.
Manual Section: Starting MotorWater pump and impeller part numbers needed for cooling system overhaul, thermostat part number also required p. 21
Find the Cooling Water System exploded view on page 21. The Pumpassy, Fan, Thermostat, and Sensor are all listed individually. Mounting hardware on that page uses M8X12PLATED bolts. Identify whether you need the full Pumpassy or just the impeller sub-component, then verify the Thermo. and Tankassy part numbers separately on page 22 if the complete cooling circuit is being serviced.
Manual Section: Cooling Water SystemExhaust manifold gasket and air cleaner element part numbers missing, can't build complete replacement parts list p. 13
Refer to the Exhaust Manifold & Air Cleaner parts list on page 13. The Manifold Gasket, Silencer, and Cleanerassy are listed as separate line items. Pull the Element (Aircleaner) part number from the same section. If a full gasket overhaul is planned, also pull the Gasket Set on page 35, which lists the Head Gasket, Valvestem Seals, and Manifold Gasket together as a bundled set.
Manual Section: Exhaust Manifold & Air CleanerCrankshaft bearing and piston ring part numbers needed after oil contamination damage, connecting rod metal unclear p. 17
Open the Crankshaft & Piston section on page 17. The PISTONW/RING assembly, Rodassy (Connecting), and Metalassy (Crankpin) are each listed with individual part numbers. The key used in that assembly is size 4X12 (page 17). Order Metalassy and PISTONW/RING as separate line items. Cross-reference with the Lub. Oil System on page 19 to also identify the Filterassy part number for the oil filter replacement.
