Figure 4 shows the basic engine components and their
functions. The manufacturer's engine manual provides
further instructions and details of operation and servicing.
1. Fuel Filter – Removes dirt and water from the engine
fuel.
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.
11. Muffler – Exhaust gases routed here through the
muffler.
12. Lifting Eye – Two lifting eyes are provided if the
removal/installation of the engine becomes necessary.
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.
15. Flywheel – Main power is taken off from the flywheel
end.
16. Air Intake Port – Provides air from the air cleaner to
the turbocharger unit.
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.
