General
Clean Emissions Intake & Exhaust Manifold
Building off the proven TNE design, Yanmar has Muffler/Exhaust Pipe Gasket (shipped loose)
achieved superior exhaust emissions by improving the
combustion chamber and fuel injection equipment Lubrication System
design. Engines are compliant with EPA Intermediate 7.4 L Capacity Deep Oil Pan, Side Drain
Tier 4 and EU stage III A exhaust emissions regulations. Trochoid Oil Pump
Paper Element Oil Filter
Reliable and Durable Oil Pressure Switch
The TNV engines now proudly take up the running as Crankcase Breather, Closed Type
Yanmar’s premium small industrial diesel. They offer
even more enhanced durability due to better block Electrical System
cooling, a stiffer crank and pistons, finer tolerance in the 12V, 40 Amp Alternator
journal, and more. CAE analysis has brought lower 12V Starter Motor
vibrations and higher strength to the mounting structure Glow Plugs
for even better reliability in heavy-duty jobs. Preheat Relay (shipped loose)
Preheat Timer (shipped loose)
Fuel Delivery and Economy Stop Solenoid Timer (shipped loose)
A newly designed, MP distributor type fuel injector pump
is utilized to assure more precise fuel delivery and Fuel System
control. The result is reduced emissions, improved Distributor Type MP2 Fuel Injection Pump
performance over a wide range of applications and good 12V Electric Fuel Pump (shipped loose)
fuel economy which assures that Yanmar’s reputation for Paper Element Fuel Filter
superior starting characteristics continues. Water Separator (shipped loose)
Stop Solenoid, Integral to Fuel Injection Pump
Noise Level Reduction
Yanmar’s original CAE techniques have optimized the Cooling System
stiffness, minimized transformation, and reduced radiant Water Pump, Belt Driven
noise in the cylinder block. Gear noise reduction is 7-Blade, 380mm Cooling Fan—Puller Type
achieved through an improved gear tooth profile 71º C (160.0º F) Thermostat
resulting in less mechanical noise. Temperature Switch
Fan Belt
