All 20 pages of this Yanmar 4TNV84-GGE Parts Catalog PDF (OEM #Y00R6210) exist for one reason: finding the correct factory part number for your diesel engine without wasting time. Open it to exploded views and parts lists covering the cylinder block, gear housing, flywheel housing, cylinder head and bonnet, fuel injection pump, governor, crankshaft and piston assembly, cooling water system, starting motor, and generator. Every diagram comes with official part numbers and cross-references, identifying components by position and assembly, not guesswork. The lubricating oil pressure switch is rated at 0.5 kg/cm²; the thermostat switch trips at 110°C. These are the factory numbers you bring to the parts counter, not estimates. Chasing the wrong part number wastes a full day. Bookmarked by assembly, this PDF lets you jump straight to the right section, pull your number, and order with confidence.

Yanmar 4TNV84-GGE Common Problems This Manual Covers
Yanmar 4TNV84-GGE injection pump assembly: can't identify delivery valve holder and feed pump sub-component part numbers p. 13
Open the injection pump assembly exploded view on pages 13-14. Locate the Delivery Valve Holder and Feed Pump Assy line items in the numbered parts list. Cross-reference each item against your serial number range before ordering. Verify whether you need the complete Pump Assy or individual sub-components such as the Piston and Delivery Valve Assy separately.
Manual Section: 011.PdfWater pump and impeller part numbers missing from order, cooling system overhaul parts hard to identify p. 12
Turn to page 12 for the cooling system exploded view. The Water Pump Assy and Drain Plug are listed as separate line items alongside the Thermo. Case components. The thermostat in this system is rated at 110°C, so confirm you are ordering the correct housing assembly matching that temperature rating before placing the order.
Manual Section: 010.PdfFuel injector part number needed, original nozzle worn and vendor asking for exact catalog reference p. 16
Find the fuel injector exploded view on page 16. Each injector component is listed with its own part number under the Fuel Injector No. entry. Cross-reference these part numbers against the parts list on page 16 to confirm fitment for your specific engine configuration before ordering.

Check the stop system exploded view on page 15. The Stop Solenoid, Retainer, Regulator, Lever, Spring, and Packing are each listed as individual part numbers. Identify whether you need the solenoid alone or the full assembly. Verify the correct Regulator part number separately to avoid ordering a mismatched governor calibration component.
Manual Section: 012.PdfOil pressure switch part number unknown, indicator fault on dash and switch replacement needed p. 11
Locate the oil system parts list on page 11. The Lubricating Oil Pressure Switch is listed there and carries a rated activation pressure of 0.5 kg/cm². Cross-reference the Switch part number in the Parts Number List on page 3. Confirm the Bracket and Pipe Assy part numbers at the same time if surrounding components also need replacement.
Manual Section: 009.PdfThermostat housing parts unclear, need correct case and plug part numbers for cooling system rebuild p. 12
Go to the cooling system parts list on page 12. The Thermo. Case and associated Drain Plug are listed as separate line items.
