HTX-YANMAR DIESEL — BASIC ENGINE INFORMATION
Figure 5. Basic Engine Components
Basic Engine Components
The following refer to basic engine components and their functions
that an operator may need to reference . The manufacturer's engine
manual provides further instructions and details of operation and
servicing. The engine shown in Figure 5 is a Yanmar engine.
2. Engine Stop Lever – This lever restricts engine speed
(high idle and low idle) through a speed control device
linked to the accelerator system.
3. Oil Dip Stick – Remove to check amount and condition of
oil in crankcase.
4. Oil Filter – Spin-on type, filters oil for contaminants.
5. Oil Drain Plug – Remove plug to drain crankcase oil.
6. Oil Filler Port – Remove to add fresh crankcase oil.
7. Crankshaft V-Pulley – Check fan V-belt between V-Pulley
and alternator to determine proper belt tension.
8. Cooling Fan – Driven by the V-belt, the cooling fan cools
the engine by cooling water/antifreeze mixture that
circulates through the engine block and cylinder head.
9. V-belt Tension Adjustment – This bolt provides means
to adjust the V-belt tension at the alternator bracket.
10. V-belt (Fan belt) – Driven by the engine crank during
operation, drives the water pump/fan as well as the
alternator.
16. Air Intake Port – Provides air from the air cleaner to the
turbocharger unit.
13. Alternator – Provides current to the electrical system and
charges the battery. Driven by means of a crankshaft/V-belt
pulley system.
14. Starter – Starts engine when ignition key is rotated to the
"START" position.
12. Lifting Eye – Two lifting eyes are provided if the removal/
installation of the engine becomes necessary.
11. Muffler – Exhaust gases routed here through the muffler.
1. Fuel Filter – Removes dirt and water from the engine fuel.
15. Flywheel – Main power is taken off from the flywheel end.
17. Turbocharger – Provides pressurized intake air to the
cylinder by means of a turbine energized by exhaust gas
that rotates the blower.
18. Throttle Lever – Controls engine rpm.
19. Fuel Pump – Provides fuel flow to injection pump.
20. Water Pump – Circulates coolant flow through engine.
21. Injection Pump – Provides equal fuel flow to injectors.
22. Air Filter – Helps provide clean source of air flow to
turbocharger and engine.
23. Fuel/Water Separator – Separates water, dirt and sludge
from fuel helping prevent engine component wear.
