SP7. CRANKSHAFT VIBRATION DAMPER
(6 Cylinder Engines Only)
1. Remove belts.
2. Try to turn the vibration damper in both direc-
tions 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 fi rst, as the vibration damper assembly is not
repairable.
3. Place a dial indicator
(Figure 16)
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
specifi cation, replace the vibration damper.
Vibration Damper Maximum
Radial Runout ..........................1.50 mm (0.060 in.)

SP8-10. FUEL FILTERS (Continued)
Figure 17 :
Secondary Fuel fi lter
c. Remove the secondary fuel fi lter by turning
the fi lter clamp
(Figure 17-B)
counter clockwise
until the fi lter cartridge
(Figure 17-C)
slides out.
NOTE: Before installing a new fi lter cartridge make
sure the surfaces where the cartridge comes in contact
with the mounting plate are absolutely clean. Dirt can
be washed into the fuel injection system. This may
result in severe damage to the fuel injection pump or
nozzles. Also, never pre-fi ll fuel fi lters as the fuel used
may be contaminated and damage the fuel system
components. Your generator set may have two
secondary fi lters, depending on the fuel supply system.
d. Install new fi lter cartridge, hand tighten until it
clicks into place.
e. Turn on the fuel, bleed the fuel system.
BLEEDING THE FUEL SYSTEM
Escaping diesel fuel under pressure can penetrate
the skin, causing serious personal injury. Before
disconnecting lines be sure to relieve all pressure.
Before applying pressure to the system be sure
all connections are tight and the lines, pipes and
hoses are not damaged. Fuel escaping from a very
small hole can be almost invisible. Use a piece of
cardboard or wood rather than the hands to search
for suspected leaks. If injured by escaping fuel, see
a doctor at once. Serious infection or reaction can
develop if proper medical treatment is not adminis-
tered immediately.
a. Turn off the fuel.
b. Open the fi lter drain plug
(Figure 17-A)
and drain
the fi lter.
