PERIODIC MAINTENANCE

5-30 TNV IDI Service Manual

Periodic Maintenance Procedures

Perform the following maintenance every 500 hours

of operation.

• Replace Air Cleaner Element

• Replace Fuel Filter

• Clean Fuel Filter / Water Separator

Replace Air Cleaner Element

Replace the air cleaner element (Figure 5-12, (2))

every 500 hours even if it is not damaged or dirty.

When replacing the element, clean the inside of the

air cleaner case (Figure 5-12, (4)).

If the air cleaner is equipped with a double element,

only remove and replace the inner element

(Figure 5-13, (1)) if the engine lacks power or the

dust indicator actuates (if equipped). This is in

addition to replacing the outer element.

Replace Fuel Filter

Every 500 Hours of Operation

CAUTION

The maximum air intake restriction, in

terms of differential pressure

measurement, must not exceed 0.90 psi

(6.23 kPa; 635 mmAq). Clean or replace

the air cleaner element if the air intake

restriction exceeds the above

mentioned value.

A 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.

CAUTION

For maximum engine life, Yanmar

recommends that when shutting the

engine down, you allow the engine to

idle, without load, for five minutes. This

will allow the engine components that

operate at high temperatures, such as

the turbocharger (if equipped) and

exhaust system, to cool slightly before

the engine itself is shut down.
