All 45 pages of this Yanmar TB014, TB016, 3TNE68-NTB, 3TNE68-TB1, and ETB1 Parts Catalog (OEM #Y00D6550, Y00D6701) exist for one purpose: finding the exact part number before you order. Inside, you get exploded views and numbered parts lists for every major assembly, from cylinder block and crankshaft to fuel injection pump, governor, starting motor, and generator. The cross-reference index at the back lets you look up any part number and trace it to its assembly group in seconds. Interchangeability marks and effective machine numbers are called out right on the diagrams, so you know immediately whether a part fits your specific variant. Your machine is down and you need the right number, not a guess from a supplier who isn't sure. Bookmarked by section, searchable by keyword: open it on your phone, pull the part number, make the call.

Yanmar TB014 / TB016 Common Problems This Manual Covers
Yanmar TB014/TB016 fuel filter O-ring part number needed to fix air ingress and hard starting p. 19
Turn to the Fuel Line exploded view on page 19. Locate the fuel filter assembly in the parts list and cross-reference the O-ring ref numbers against the Parts No. Index on page 24 to confirm exact part numbers for your serial range. Check the interchangeability marks on page 1 before ordering, some O-rings share part numbers across the TB014 and TB016.
Manual Section: Fuel LineCan't identify correct injection nozzle and holder assembly part numbers for white smoke diagnosis p. 18
Open the Fuel Injection Valve exploded view on page 18. The nozzle and holder are listed as a sub-assembly, note both ref numbers separately, since nozzles and holders are often ordered independently. Cross-check both part numbers in the Parts No. Index on page 24 and verify the effective machine number column applies to your serial range.
Manual Section: Fuel Injection ValveNeed fuel injection pump plunger and delivery valve part numbers after contaminated fuel damage p. 15
Go to page 15 for the Fuel Injection Pump exploded view. Plungers, delivery valves, and the rack and pinion assembly are each listed with individual ref numbers. Write down all ref numbers before calling the dealer, the pump tappet assembly is a separate line item. Confirm interchangeability marks per the guide on page 1, as plunger kits sometimes changed effective machine numbers mid-production.
Manual Section: Fuel Injection PumpCorrect part numbers for valve guides, valves, and springs after worn valve seat causes compression loss p. 7
Check the Cylinder Head and Bonnet diagram starting on page 7. Intake and exhaust valves, guides, and springs each carry distinct ref numbers, do not assume they are interchangeable between positions. The complete gasket set on page 23 includes the head gasket and valve cover gasket; order it alongside individual valve components to avoid a second disassembly.
Manual Section: Cylinder Head & BonnetOil filter and oil pump assembly part numbers needed after low oil pressure warning and bearing damage concern p. 13
Locate the Lub. Oil System diagram on page 13. The oil filter, oil intake pipe, and oil pressure switch are listed as separate line items, order all three if the engine showed low pressure. The Parts No. Index on page 24 lets you verify each part number independently. If main bearings need replacement, the undersized bearing (U.S. = 0.25) is listed on page 3 under Cylinder Block.
Manual Section: Lub. Oil SystemWater pump and thermostat part numbers needed after overheating event on a Yanmar compact engine p. 14
Reference the Cooling Water System diagram on page 14. The water pump assembly, thermostat, and thermo switch (rated 110°C) are each separate line items. Cross-reference part numbers in the Parts No. Index on page 24 before ordering. If hoses or the radiator sub-tank also need replacement, all cooling hoses are listed on the same page 14 diagram.

What is the fuel injection nozzle assembly part number?
The Fuel Injection Valve exploded view on page 18 lists the nozzle assembly as Part No. 119620-53000 (NOZZLE ASSY, F. INJECT). Note the nozzle and holder ref numbers separately, since they are often ordered independently.
How do I find the water pump and thermostat part numbers?
See the Cooling Water System diagram on page 14. The water pump assembly, thermostat, and thermo switch (rated 110C) are each separate line items. Cross-reference each in the Parts No. Index on page 24 before ordering.
Where are the oil filter and oil pump part numbers listed?
The Lub. Oil System diagram on page 13 lists the oil filter, oil intake pipe, and oil pressure switch as separate line items. Verify each part number in the Parts No. Index on page 24 before ordering.
What part numbers cover the valves, guides, and springs?
The Cylinder Head & Bonnet diagram starting on page 7 lists intake and exhaust valves, guides, and springs with distinct ref numbers. The complete gasket set on page 23 includes the head and valve cover gaskets.
