Yanmar 4TNV98T-ZSTBW, P-T175WECF Common Problems This Manual Covers
Yanmar 4TNV98T-ZSTBW fuel filter assembly and injection pump part numbers needed after no-start condition p. 38
Check the Fuel Line exploded view on page 38. The fuel filter assembly, body, and fuel sensor components are identified by part number in that diagram. For injection pump, delivery valve holders, and timer set part numbers, cross-reference the Fuel Injection Pump section starting on page 32. Confirm serial number applicability before ordering any fuel-system component.
Manual Section: Fuel LineWater pump, thermostat, and drive belt part numbers needed for cooling system overhaul, engine overheating p. 30
Check the Cooling Water System exploded view on page 30. Water pump assembly, V-pulley, cooling fan, and thermostat part numbers are all listed in that diagram. The replacement v-belt is size B45 (or B44.5 depending on configuration), confirmed on page 31. Order all pipe assemblies and hose fittings from the same section by part number.
Manual Section: Cooling Water SystemCylinder head gasket set part number needed for rebuild after overheating and coolant contamination p. 46
Check the Gasket Set section starting on page 46. The index on page 48 lists individual gasket and seal part numbers, including the cylinder head gasket, O-rings, valve stem seals, and intake manifold packing. Confirm whether the full NON-ASB. gasket set covers your repair scope, or identify individual components by part number for a partial order.
Manual Section: Gasket SetStarter motor subassembly part numbers needed, engine cranks slowly or starter fails to engage p. 40
Check the Starting Motor exploded view on page 40. The armature assembly, field coil, brush set, magnetic switch assembly, pinion assembly, and clutch assembly are each listed by individual part number in that diagram. This starter is rated 12V, 3KW (page 41). Verify voltage compatibility before ordering any subassembly or a complete starter unit.
Manual Section: Starting MotorOil pressure switch and lube line part numbers unclear after oil pressure warning light comes on p. 28
Check the Lub.Oil Line exploded view on page 28. The oil pressure switch, check valve assembly, pipe joints, and seal washers are listed by part number on page 29. The switch activates at 0.5 kg, so also cross-reference the Lub.Oil System on page 26 to identify oil cooler assembly and bracket part numbers if restriction or contamination is suspected.
Manual Section: Lub.Oil LineTurbocharger gasket and mounting hardware part numbers missing, engine losing power or producing smoke p. 20
Check the Turbine section on page 20. The RHF5 turbocharger gasket and mounting nuts are individually listed by part number in that diagram. For intake-side components including the EGR valve, EGR cooler pipes, and suction manifold reed valve, check page 14. Exhaust manifold gaskets and remaining EGR-related components are listed on page 16.
