Part of the Yanmar Parts Manuals.
All 43 pages of this Yanmar TB135 Parts Catalog focus on one job: finding the exact part number for your 3TNV88-QTB2 engine before you waste an afternoon chasing the wrong component. Inside, you get exploded views and numbered parts lists across 18 figures covering every major assembly - cylinder block, gear housing, flywheel housing, crankshaft and piston, fuel injection pump with inner parts and governor, starter motor, alternator, and the complete gasket set. Each figure pairs a detailed exploded diagram with a cross-referenced parts table so you can identify a component visually and pull its Yanmar part number in one step. Your cooling system section calls out the V-belt size split by serial number: A37 before S/N 13519312, A37.5 from that point forward - the kind of detail that prevents a wrong-size order. Your machine is down; stop guessing at part numbers. Bookmarked and searchable, this PDF lets you jump straight to any assembly by keyword or section.

Yanmar TB135 3TNV88-QTB2, TB135, 3TNV88-QTB2 Common Problems This Manual Covers
Yanmar TB135 head gasket part number needed for 3TNV88-QTB2 engine rebuild after overheating p. 11
Open the Cylinder Head & Bonnet exploded view starting on page 11. The head gasket is listed in the parts number table on page 12. Cross-reference the Gasket Set section starting on page 39; the index on page 41 groups all gasket and seal components by subsystem, which helps confirm you have the complete set for a head job. Verify your serial number range before ordering.
Manual Section: Cylinder Head & BonnetWater pump assembly part number unclear, can't confirm which coolant hose connects to radiator p. 23
Check the Cooling Water System exploded view on page 23. The water pump assembly, V-belt, fan, thermostat, and radiator assembly are all itemized there. For the TB135 3TNV88-QTB2, the radiator cap is rated at 0.9 kgf/cm² (page 24) — confirm the replacement cap matches that spec. Cross-reference hose routing in the same diagram to identify the correct inlet and outlet hose part numbers.
Manual Section: Cooling Water SystemCan't identify correct alternator part number or output spec for charging circuit diagnosis p. 37
Turn to the Generator section on page 37. The exploded view covers the alternator, rotor assembly, ball bearing, regulator assembly, adjuster, and belt. The alternator output is rated at 40A (page 38) — use this to verify any replacement unit matches spec. The belt adjuster components are also listed there if the charging problem traces back to a slipping belt.
Manual Section: GeneratorGlow plug or stop solenoid part number needed for no-start electrical fault p. 29
Check the Governor (Inner Parts) section on page 29 for the stop solenoid and idle limit components. For glow plugs, go to the Suction Manifold & Air Cleaner section on page 13 where the air heater is listed alongside intake manifold parts. Confirm part numbers against the table on the facing page before ordering, as the air heater assembly and individual heater element may have separate line items.
Manual Section: Governor (Inner Parts)Need correct fuel filter and separator part numbers for fuel system service p. 33
Open the Fuel Line section on page 33. The parts list covers the fuel filter, fuel pump, separator assembly, and all fuel pipe runs. Cross-reference with the Fuel Injection Pump diagram on page 25 to confirm the upstream filter bracket and mounting hardware part numbers. Order both the filter element and the separator as separate line items — they are listed independently in the table.
Manual Section: Fuel LineTurbocharger oil feed seal kit part numbers missing from engine rebuild parts list p. 21
Start with the Lub. Oil System on page 21. The oil inlet pipe assembly, filter, and cooler inlet components are listed there. For gasket and seal kits covering the full engine, check the Gasket Set index on page 41, which organizes O-rings, valve stem seals, and nozzle protectors by system. If turbocharger-specific seals are not shown in these sections, note that the catalog may not list turbo sub-components separately — cross-reference with a Yanmar dealer using the engine serial number to identify the correct oil feed seal kit.
