Check and Adjust Cooling Fan V-Belt
The V-belt will slip if it does not have the proper tension. This will
prevent the alternator from generating sufficient power. Also, the
engine will overheat due to the engine coolant pump pulley slipping.
Check and adjust the V-belt tension (deflection) as follows:
1. Press the V-belt down with your thumb with a force of
approximately 22 ft•lb (98 N•m; 10 kgf) to check the deflection.
There are three positions to check for V-belt tension (A, B
and C, Figure 78). You can check the tension at whichever
position is the most accessible. The proper deflection of a
used V-belt at each position is:
NOTE: A "Used V-Belt" refers to a V-belt which has been
used on a running engine for five minutes or more.
2. If necessary, adjust the V-belt tension. Loosen the
adjusting bolt (1, Figure 79) and move the alternator (2,
Figure 79) with a pry bar (3, Figure 79) to tighten the V-belt
to the desired tension. Then tighten the adjusting bolt.
3. Tighten the V-belt to the proper tension. There must be
clearance (1, Figure 80) between the V-belt and the bottom
of the pulley groove. If there is no clearance (2, Figure 80)
between the V-belt and the bottom of the pulley groove,
replace the V-belt.
4. Check the V-belt for cracks, oil or wear. If any of these
conditions exist, replace the V-belt.
5. Install the new V-belt. Refer to the table for proper tension.
6. After adjusting, run the engine for 5 minutes or more. Check
the tension again using the specifications for a used V-belt.

DANGER
Fire And Explosion Hazard!
Diesel fuel is flammable and explosive under certain
conditions.
When you remove any fuel system component to perform
maintenance (such as changing the fuel filter) place an
approved container under the opening to catch the fuel.
Never use a shop rag to catch the fuel. Vapors from the rag

Check Battery
Batteries in Cold Weather
In colder weather a greater drain is placed on the batteries when
they are used for the preheat cycle and when starting a cold
engine. Battery performance decreases as the temperature gets
lower.
In extremely cold weather, remove batteries at night and move
them to a warm location. This will help to keep them at a higher
power level.
WARNING
Battery electrolyte contains sulfuric acid and can quickly
burn the skin and eat holes in clothing. If you spill acid on
yourself, immediately flush the area with water.
Battery acid could cause blindness if splashed into the
eyes. If acid gets into the eyes, flush them immediately with
large quantities of water and see a doctor at once.
If you accidentally drink acid, drink a large quantity of water
or milk, beaten egg or vegetable oil. Call a doctor or poison
prevention center immediately.
When working with batteries, always wear safety glasses or
goggles.
Battery generates hydrogen gas, so there is a danger of an
explosion. Do not bring lighted cigarettes near the battery,
or do anything that will cause sparks.
Before working with batteries, shut down engine and turn
the starter switch to the "O" (OFF) position.
Avoid short-circuiting the battery terminals through acci-
dental contact with metallic objects, such as tool.
When removing or installing, check which is the positive (+)
terminal and negative (-) terminal.
When removing the battery, first disconnect the negative (-)
terminal. When installing the battery, first connect the posi-
tive (+) terminal.
If the terminals are loose, there is a danger that defective
contact may generate sparks that will cause an explosion.
When installing the terminals, install them tightly.
19. SP001434Engine

Inspection of Battery Electrolyte Level
This machine has two maintenance free battery. It never
requires the addition to water.
When the charge indicator becomes transparent, it means low
electrolyte state because of the leakage or charging system
error. Determine the cause of problem and replace the battery
immediately.
Check Charging State
Check charging state through the charging indicator.
• GREEN: Sufficiently charged.
• BLACK: Insufficient charged.
• TRANSPARENT: Replace battery.
Check the Battery Terminals
Be certain that battery is held securely in its compartment. Clean
the battery terminals and the battery cable connectors. A
solution of baking soda and water will neutralize acid on the
battery surface, terminals, and cable connectors. Petroleum jelly
or grease can be applied to the connectors to help prevent
corrosion.
Battery Replacement
When the charging indicator indicates transparency state,
replace the battery.

Note that a typical air cleaner is shown in Figure 89 and Figure
91 for illustrative purposes only.
The engine performance is adversely affected when the air
cleaner element is clogged with dust. Be sure to clean the air
filter element periodically.
1. Unlatch and remove the air cleaner cover (1, Figure 89,).
2. Remove the element (2, Figure 89) (outer element if
equipped with two elements).
3. Blow air (3, Figure 89) through the element from the inside
out using 42 -71 psi (0.29 -0.49 MPa; 3.0 -5.0 kgf/cm2)
compressed air to remove the particulates. Use the lowest
possible air pressure to remove the dust without damaging
the element.
4. If the air cleaner is equipped with a double element, only
remove and replace the inner element (1, Figure 91) if the
engine lacks power or the dust indicator actuates (if
equipped).
5. The inner element should not be removed when cleaning
or replacing the outer element. The inner element is used
to prevent dust from entering the engine while servicing the
outer element.
6. Replace the element with a new one if the element is
damaged, excessively dirty or oily.
7. Clean inside of the air cleaner cover.
8. Install the element into the air cleaner case (4, Figure 89).
9. Reinstall the air cleaner cover making sure you match the
arrow (5, Figure 89) on the cover with the arrow on the
case (6, Figure 89).
10. Latch the air cleaner cover to the case.

CAUTION
FLYING OBJECT HAZARD!
Always wear eye protection when servicing the engine
and when using compressed air or high-pressure
water. Dust, flying debris, compressed air, pressurized
water or steam may injure your eyes.
Failure to comply may result in minor or moderate injury.
Figure 91
CAUTION
When the engine is operated in dusty conditions, clean
the air cleaner element more frequently.
Never operate the engine with the air cleaner
element(s) removed. This may allow foreign material to
enter the engine and damage it.

DANGER!
Fire And Explosion Hazard!
Diesel fuel is flammable and explosive under certain
conditions.
When you remove any fuel system component to perform
maintenance (such as changing the fuel filter) place an
approved container under the opening to catch the fuel.
Never use a shop rag to catch the fuel. Vapors from the rag
are flammable and explosive. Wipe up any spills
immediately.
Wear eye protection. The fuel system is under pressure and
fuel could spray out when you remove any fuel system
component.
Failure to comply will result in death or serious injury.

agencies for the proper disposal of hazardous materials
such as engine oil, diesel fuel and engine coolant. Consult
the local authorities or reclamation facility.
Never dispose of hazardous materials irresponsibly by
dumping them into a sewer, on the ground, or into ground
water or waterways.
Failure to follow these procedures may seriously harm the
environment.

That a typical fuel tank is illustrated.
1. Position an approved container under the diesel fuel tank
(1, Figure 94) to collect the contaminates.
2. Remove the fuel cap (3, Figure 94).
3. Remove the drain plug (2, Figure 94) of the fuel tank to
drain the contaminates (water, dirt, etc.) from the bottom of
the tank.
4. Drain the tank until clean diesel fuel with no water and dirt
flows out. Reinstall and tighten the drain plug firmly.
5. Reinstall the fuel cap.
6. Check for leaks.
Replace Engine Oil and Engine Oil Filter
Change the engine oil every 250 hours of operation after the
initial change at 50 hours. Replace the engine oil filter at the
same time. See “Replace Engine Oil and Engine Oil Filter” on
page -79
Figure 94
CAUTION!
Only use the engine oil specified. Other engine oils may
affect warranty coverage, cause internal engine
components to seize and / or shorten engine life.
Prevent dirt and debris from contaminating the engine oil.
Carefully clean the oil cap / dipstick and the surrounding
area before you remove the cap.
Never mix different types of engine oil. This may adversely
affect the lubricating properties of the engine oil.
Never overfill. Overfilling may result in white exhaust
smoke, engine overspeed or internal damage.
