All 42 pages of this Yanmar 3TNV70-PTB1R, P-T215REAA Parts Catalog map factory components for the 3TNV70-PTB1R engine, from cylinder block hardware straight through the generator and complete gasket set. Inside: 17 system sections with exploded views and OEM part numbers covering fuel injection pump internals (plunger assy, delivery valve, rack), governor linkage, crankshaft and piston assembly, starting motor, and every seal and O-ring in the Gasket Set. Cross-referencing a camshaft tappet, a gear housing rotor, or a cooling water pump assy takes seconds when every subcomponent is indexed by assembly. Yanmar breaks the fuel injection valve section down to individual nozzle assy, shim sets, and check valves , the exact granularity you need to order one correct part instead of a whole kit. Chasing a part number online wastes time you don't have. Bookmarked by system, this PDF opens on any device; go straight to your assembly and order the right component on the first try.

Yanmar 3TNV70-PTB1R, P-T215REAA Common Problems This Manual Covers
Yanmar 3TNV70-PTB1R fuel filter and water separator part numbers for complete fuel system service p. 32
Turn to the Fuel Filter exploded view on page 32. Locate the Filter Assy, Separator Assy, and fuel feed pump components in the parts list. Cross-reference the Element part number against your serial number range before ordering — there are multiple element variants in this family. Order the separator and filter element together; they share a service interval.
Manual Section: Fuel FilterWater pump impeller and pump assembly part numbers to resolve overheating on a 3-cylinder engine p. 24
Check the Cooling Water System diagram on page 24. The Pump Assy, impeller (listed under Water), V-Pulley, and Thermostat all appear as separate line items. Identify the pump assembly part number first, then pull the impeller and thermostat part numbers individually — these are commonly ordered as a group during cooling system overhaul.
Manual Section: Cooling Water SystemGlow plug part numbers and cylinder head gasket kit needed for hard cold-start diagnosis p. 12
Open the Cylinder Head and Bonnet section on page 12. The Head Assy, Gasket, Valve, and associated hardware are itemized in the parts list. For glow plugs, cross-check the Cylinder Block parts list on page 7 — plugs are listed there alongside block hardware. Confirm quantity per cylinder (this is a 3-cylinder engine) before ordering.
Manual Section: Cylinder Head & BonnetFuel injection nozzle and nozzle assembly part numbers for low-power or white smoke complaints p. 30
Go to the Fuel Injection Valve section on page 30. The Valve Assy, Nozzle Assy, Shim Set, and Check Valve each carry separate part numbers. Note the Shim Set — nozzle opening pressure is set by shim thickness, so order the full shim set if the nozzles are being replaced or recalibrated. Pipe Assy fittings are on the same spread.
Manual Section: Fuel Injection ValveInjection pump plunger and delivery valve part numbers for persistent fueling problems after basic filter service p. 26
Reference the Fuel Injection Pump diagram on page 26. Plunger Assy, Delivery Valve, Tappet Assy, and Rack are all listed as discrete serviceable components. Identify the Fie (fuel injection element) Assy number first — it determines compatibility for plunger and delivery valve sub-components. The Governor section on page 28 carries the rack linkage and solenoid if the rack is suspect.
Manual Section: Fuel Injection PumpComplete gasket set part numbers for engine overhaul covering head, seals, and O-rings p. 40
The Gasket Set index on page 40 maps every gasket, O-ring, valve stem seal, and crush washer in the engine. Use the index to pull only what you need, or order the full set for a complete inframe rebuild. Head Gasket part numbers listed here correspond to the Cylinder Head section on page 12 — verify they match before purchasing to avoid a gasket that fits the block deck but not the head bolt pattern.
