All 44 pages of this Yanmar TB138FR Parts Catalog focus on one thing: pinpointing the exact part number for your 3TNV88-XTBZ engine before you waste a trip to the dealer. Inside, exploded-view figures walk you through every assembly from the cylinder block and crankshaft to the fuel injection pump inner parts and governor solenoid. You get precise part numbers for the cylinder head rocker assembly, camshaft driving gear, fuel injector nozzle holder, starting motor field coil, alternator regulator, and the complete gasket set with O-ring callouts. Cross-reference the 3TNV88-XTBZ cooling water pump, thermostat, and V-belt in Fig. 10 or pull the radiator sub-tank cap part number from Fig. 11 without guessing. Stop ordering wrong parts off memory. Bookmarked by system, so you tap the section, confirm the number, and submit the order.

Yanmar TB138FR, 3TNV88-XTBZ Common Problems This Manual Covers
Yanmar TB138FR fuel filter part number unclear, need correct replacement for full fuel line assembly p. 31
Open the Fuel Line section on page 31. The filter, separator assembly, O-rings, bracket, and pipe components are each listed with individual part numbers. Pull the exploded view and trace every fitting along the fuel path from tank to pump: ordering a complete set in one pass avoids a second delivery when a downstream O-ring turns out to be missing.
Manual Section: Fuel LineNeed correct injector nozzle holder assembly part numbers, unsure which sub-components are sold separately p. 29
Turn to the Fuel Injection Valve section on page 29. The nozzle, holder assembly, high-pressure pipe assembly, retainer, and clamp are all listed individually with separate part numbers. This is a 3-cylinder engine, so confirm you are pulling 3 complete injector sets. Cross-reference the exploded view to identify each sub-component before placing the order.
Manual Section: Fuel Injection ValveWater pump and thermostat part numbers needed, unclear which gasket and pipe pieces are included p. 23
Check the Cooling Water System section on page 23. The pump assembly, connecting pipes, thermostat, fan, V-belt, and gasket are listed individually. Locate each component in the exploded view and confirm whether the gasket is bundled with the pump assembly or carried as a standalone line item before ordering to avoid a gap in the kit.
Manual Section: Cooling Water SystemCan't find correct rocker arm and valve part numbers for cylinder head assembly rebuild p. 11
Open the Cylinder Head & Bonnet section on page 11. The head assembly, rocker shaft assembly, rocker arm assembly, and intake valves are each listed separately. For a 3-cylinder engine verify the per-cylinder valve count in the exploded view and order accordingly: mixing intake and exhaust valve part numbers is the most common sourcing error on this head.
Manual Section: Cylinder Head & BonnetUnsure which gasket set covers a complete engine overhaul, individual gaskets listed throughout catalog p. 37
Refer to the Gasket Set & Tool section on page 37. A complete gasket set is listed alongside individual gaskets, O-rings, and seals with separate part numbers for each. Compare the set contents against every component removed during disassembly. If a specific seal is absent from the kit, locate its standalone part number in the relevant system section of this catalog.
Manual Section: Gasket Set & ToolInjection pump inner timer set and valve assembly part numbers missing from main pump section p. 39
Find the inner pump components in the Fuel Injection Pump (Inner Parts) section on page 39. The joint, valve assembly, barrel plug, lifter, timer set, and damper assembly each carry individual part numbers separate from the outer pump assembly on page 27. Cross-reference both exploded views against your disassembly to confirm you have the correct variant for each layer before ordering.

Document Quality
This document is a scanned parts catalog with an OCR text layer, allowing you to search and copy text throughout the document. The text quality is crisp and clear, making it easy to read all descriptions and part numbers. Diagrams and illustrations are raster images, so while labels are generally readable, they may show some pixelation if zoomed in significantly. The pages are clean, free from scan artifacts, stains, or skewed content. There are no notable blank or filler pages present.
