Servicing

2. Change secondary fuel filter every 500 hours.

NOTE:

The fuel filter on the engine is considered the

“secondary fuel filter”. The engine will be fitted with a
quick change disposable secondary fuel filter.

SP7. CRANKSHAFT VIBRATION DAMPER

(6 Cylinder Engines Only)

1. Remove belts.

2. Try to turn the vibration damper in both directions

while grasping it with both hands. If rotation can be

felt, the damper is defective and should be replaced.

NOTE:

The vibration damper assembly should be

replaced every 4500 hours or 60 months, whichever
occurs first, as the vibration damper assembly is

not

repairable.

3. Place a dial indicator

(Figure 13)

so that the probe

contacts the damper’s outer diameter in order to

check the damper radial runout.

4. Make sure the engine is at operating temperature,

then rotate the crankshaft using the JD281A,

JDE81-4, or the JDE83 Flywheel Turning Tool.

5. If the runout reading exceeds the below

specification, replace the vibration damper.

Vibration Damper Maximum

Radial Runout ..........................1.50 mm (0.060 in.)

FUELS - GENERAL

1. Use only clean, high quality fuels of the following

specifications, as defined by ASTM designation D975 for

diesel fuels:

a. Use Grade No. 2 diesel at ambient temperatures

above freezing 30°F (0°C).

b. Use Grade No.1 at ambient temperatures below

freezing and for all temperatures at an altitude of

above 5,500 ft. (1500 meters).

2. Sulphur content should not exceed 0.5% (preferably less than 0.5%).

3. The cetane number should be a minimum of 45.

4. DO NOT use these unsuitable grades of fuel:

a. Domestic heating oils, all types, b. Class B engine,

c. Class D domestic fuels, d. Class E, F, G or H industrial

or marine fuels,

e. ASTM-D975-60T No. 4-D and higher

number fuels, f. JP4

5. Storing fuel:

a. Keep dirt, scale, water and other foreign matter

out of fuel.

b. Avoid storing fuel for long periods of time.

c. Fill the fuel tank at the end of each day's operation. This

will reduce condensation.

6. Biodiesel:

Biodiesel involves the transesterification of vegetable oils or animal fats.

Mainly in the U.S. soybean methyl ester is used (SME), but in Europe
mainly rapeseed (canola) methyl ester is made (RME), and in Asia palm
methyl ester is made (PME). 100% biodiesel (B100) is made in compliance

with ASTM D6751 or EN14214 (EU) specifications. Biodiesel may be used

in a 5% blend (5% biodiesel/ 95% diesel) from a BQ-9000 accredited pro-
ducer. 20% biodiesel blends can only be used if they meet ASTM D6751 or

EN14214 (EU) specifications. A 2% reduction in power and a 3% reduction

in fuel economy can be expected using a 20% blend, and a fuel conditioner
is recommended. Biodiesel blends must be used within 90 days of their
manufacture. Oil level, leaking, microbial growth, plugging, and component
degradation all must be checked more frequently using biodiesel blends.

Request a certificate of analysis from an approved biodiesel fuel distributor
to make sure the blend meets specifications.

NOTE: Using raw pressed or partially refined vegetable oils or recycled
greases as fuel (which have not been through transesterification) could

cause engine failure.

SP8-10. FUEL FILTERS

1. Your engine or generator set should have a primary

fuel filter installed. We recommend the Racor brand of fuel

filter - water separators.

a. Check the primary fuel filter daily as recommended by the

filter manufacturer. Empty the collection bowl as necessary.

b. Change the element every 250 hours (500 for electroni-

cally controlled fuel system units) or whenever necessary.

c. If the bowl fills with water, change the primary and
