Part of the Yanmar Parts Manuals.
Strip the bonnet off a Yanmar 4TNV106T-XTBL and every valve guide, stem seal, and spring you lift out has to go back on order by its exact number. This parts catalog, Yanmar publication YOOF2161, covers the 4TNV106T-XTBL under specification P-TL150EBB, serial numbers 21500628 through 21503359, with a separate gear housing figure for engines from serial 21503360 onward, so it fits your engine wherever it happens to be mounted.
Nineteen exploded-view figures walk the whole engine: cylinder block, crankshaft and piston, camshaft and driving gear, cylinder head, turbine, fuel injection pump and valve, lubricating oil and cooling water systems, starting motor, generator, and a full gasket set. The text is Japanese, but the drawings and Yanmar part numbers read the same in any language.
It arrives as a 46-page PDF you can print, mark up, and leave on the bench beside the crates of parts.

Yanmar 4TNV106T-XTBL, P-TL150EBB Common Problems This Manual Covers
Black smoke at idle and under load
Owners of this engine report heavy black smoke when cranking, at idle, and under load, and a tired turbocharger is a frequent culprit. The Turbine figure lists the RHF5 turbocharger assembly along with its studs, nuts, washers, and inlet packing, so you can order a complete unit or just the mounting hardware for a reseal.
Manual Section: Turbine p. 22Heavy oil consumption after low hours
Oil use that climbs after relatively few hours usually ends at the rings. The Crankshaft & Piston figure identifies the piston with rings, ring sets, connecting rod assemblies, and crankshaft assembly, so a bottom-end refresh starts with the right numbers on the order sheet.
Manual Section: Crankshaft & Piston p. 24Hard starting in cold weather
Cold no-starts on this engine often trace to the intake air heater or a choked air cleaner. The Suction Manifold & Air Cleaner figure lists the air heater, intake manifold packing, and both the inner and outer air cleaner elements.
Manual Section: Suction Manifold & Air Cleaner p. 16Fuel starvation and no-start
Blocked filters and dirty fuel come up repeatedly in no-start complaints on these engines. The Fuel Line figure covers the fuel oil filter, feed and return pipe assemblies, and pipe protectors, so you can renew the whole supply path in one order.
Manual Section: Fuel Line p. 36Overheating
A failing water pump, stuck thermostat, or leaking cooling pipe will cook any diesel. The Cooling Water System figure lists the water pump assembly, thermostat, fan, cooling water pipes, and radiator assembly with their part numbers.
Manual Section: Cooling Water System p. 30Oil leaks at the sump and rear seal
Oil weeping from the pan rail or the flywheel end is a common sight on higher-hour engines. The Flywheel Housing & Oil Sump figure identifies the rear oil seal, oil pan, drain plug, and gaskets so the reseal goes together with fresh parts.
Manual Section: Flywheel Housing & Oil Sump p. 12Injector knock and rough running
Fuel knock and misfire often come back to worn nozzles. The Fuel Injection Valve figure lists the complete injector assembly plus the nozzle, holder, spring, and high-pressure pipe assemblies individually, so you can rebuild or replace as your pop tester dictates.
Manual Section: Fuel Injection Valve p. 34Frequently Asked Questions
Which engines and serial numbers does this catalog cover?
It covers the Yanmar 4TNV106T-XTBL, specification P-TL150EBB, serial numbers 21500628 through 21503359. The Gear Housing system is split into two figures, one for that serial range and one for engines from serial 21503360 onward, so check your serial plate before ordering gear case parts. p. 8
Is the catalog in English?
No, the text is Japanese. In practice that matters less than it sounds: each system is an exploded drawing keyed to a numbered part listing, and Yanmar part numbers are the same worldwide. You identify the part from the figure and order by number.
Does it include torque specs or rebuild procedures?
No. This is a parts catalog, not a service manual. It identifies every part from the Cylinder Block figure through the Gasket Set and shows how assemblies fit together in the exploded views, but procedures, clearances, and torque sequences are not part of this publication.
Can I find seal and gasket numbers for a reseal?
Yes. The Gasket Set section lists the head gasket, valve stem seals, O-rings, and bonnet packing, and each system figure, such as Flywheel Housing & Oil Sump, also lists its own oil seals and gaskets in place. p. 42
What do I get after purchase?
A 46-page PDF of about 3.5 MB as an instant download. It prints cleanly, so you can take just the figure you need to the bench, mark it up, and keep the oily fingerprints off your screen.
Is this Yanmar 4TNV106T-XTBL manual a download or a disc?
You get a 46-page searchable PDF that downloads instantly after checkout. Open it on your laptop, tablet, or phone, and bring it right to the shop floor.
Can I print specific sections of this Yanmar 4TNV106T-XTBL Parts Catalog?
Absolutely. No DRM or copy protection. Print the whole manual or just the pages you need. Any home or office printer works.
