Part of the Yanmar Parts Manuals.
Somewhere between pulling the injection pump and putting it back, you need the exact Yanmar part number, not a guess from a cross-reference chart. This parts catalog (Yanmar publication Y00R5270) covers the 4TNE106-SA, 4TNE106-G1A, 4TNE106T-SA, and 4TNE106T-G1A engines, laying out every assembly from cylinder block to gasket set across 23 pages, with quantity columns for each variant so you know what your specific engine takes.
Each section covers one system: crankshaft and piston, camshaft and driving gear, lubricating oil, cooling water and radiator, fuel injection pump and valves, starting motor, and the turbine section for the turbocharged T models. A rod bearing or head gasket ordered on a hunch can cost you a week of downtime; this book exists so that never happens.
It is a 0.65 MB PDF you buy once and keep: open it on a phone at the engine stand, or print the pages you need for a shop copy.

Yanmar Yanmar 4TNE106-4TNE106T Series Common Problems This Manual Covers
Hard starting and fuel drain-back
A 4TNE106 that cranks but only fires with a starting aid usually has air getting into the fuel through aged lines and fittings, letting fuel drain back overnight. The Fuel Line section lists the pipes, joints, and hardware to renew when you chase the leak.
Manual Section: Fuel Line p. 17Overheating under load
Blocked coolant passages, a stuck thermostat, or a tired water pump will push these engines hot when worked hard. The Cooling Water System section identifies the thermostat and pump components by part number so you replace the right pieces instead of parts-cannon guessing.
Manual Section: Cooling Water System p. 13Low oil pressure after neglected changes
Delayed oil and filter changes are the classic route to bearing burn-in on Yanmar diesels, and by the time the pressure drops the damage is spreading. The Lub.Oil System section covers the pump and related components you need when rebuilding the oiling circuit.
Manual Section: Lub.Oil System p. 11Clogged injectors, white smoke, rough running
Contaminated fuel plugs nozzles, and a dribbling injector shows up as white smoke, rough running, and a miss under load. The Fuel Injection Valve section gives the injector assembly part numbers for all four engine variants.
Manual Section: Fuel Injection Valve p. 16Oil leaks at the sump and housings
Seals and gaskets around the flywheel housing and oil sump harden with age and start weeping. The Flywheel Housing & Oil Sump section lists the sump hardware down to the drain plug, so you can reseal the bottom end in one pass instead of chasing leaks one part at a time.
Manual Section: Flywheel Housing & Oil Sump p. 3Turbocharger wear on the T variants
On the 4TNE106T-SA and 4TNE106T-G1A, oil neglect and dirty intake air take out the turbo long before the bottom end. The Turbine section covers the turbocharger parts specific to these turbocharged models.
Manual Section: Turbine p. 9Slow cranking, tired starter
A dragging starter makes every cold-weather no-start worse, and a worn drive or solenoid is often mistaken for a battery problem. The Starting Motor section identifies the starter assembly and its components so you order the correct replacement the first time.
Manual Section: Starting Motor p. 20Frequently Asked Questions
Which engine models does this parts catalog cover?
It covers four Yanmar engine variants: 4TNE106-SA, 4TNE106-G1A, 4TNE106T-SA, and 4TNE106T-G1A. The parts tables carry a quantity column for each variant, so you can see exactly which components and how many apply to your specific engine.
Does this include torque specs or repair procedures?
No. This is the factory parts catalog (publication Y00R5270): part numbers, component listings, and per-model quantities organized by system, from Cylinder Block through Gasket Set. It is the reference for ordering correct parts during a rebuild, not a service manual with clearances and procedures.
Are turbocharger parts included?
Yes. The Turbine section lists the turbocharger components that apply to the turbocharged 4TNE106T-SA and 4TNE106T-G1A models, alongside the intake and exhaust sections that feed it. p. 9
Does it cover gaskets and seals for a full reseal?
Yes. Gaskets appear within each system's listing, and a dedicated Gasket Set section at the end of the catalog covers the set itself, useful when you are resealing the engine during a rebuild. p. 23
Is this Yanmar 4TNE106-SA Parts Catalog a digital download?
A 23-page Parts Catalog in searchable PDF format, available the moment you complete checkout. View on computer, tablet, or phone, with no shipping wait.
Does this Yanmar 4TNE106-SA manual allow printing?
The PDF is DRM-free. Print whatever sections you need to take out to the shop. Standard letter or A4 paper works.
