WARNING: DO NOT ATTEMPT TO DRAIN WATER
FROM THE FILTER/SEPARATOR WITH THE ENGINE
HOT.
(1) The bottom of the filter/separator bowl is
equipped with a drain valve (Fig. 29). The drain
valve is equipped with a fitting. Attach a piece of
rubber hose to this fitting. This hose is to be used as
a drain hose.
(2) Place a drain pan under the drain hose.
(3) With the engine not running, open the drain
valve (unscrewÐdrain valve has right hand threads)
from the filter/separator bowl. To gain access to this
fitting, the two filter±to±mounting bracket nuts (Fig.
29) may have to be loosened a few turns.
(4) Hold the drain open until clean fuel exits the
drain.
(5) After draining, close drain valve.
(6) Remove rubber drain hose.
(7) Dispose of mixture in drain pan according to
applicable local or federal regulations.
FUEL FILTER REMOVAL
(1) Drain all fuel and/or water from fuel filter/wa-
ter separator assembly. Refer to the previous Drain-
ing Water From Filter Bowl.
(2) Unplug the electrical connectors at bottom of
plastic bowl.
(3) Remove plastic bowl from bottom of fuel filter
(unscrews).
(4) Remove fuel filter from bottom of filter base
(unscrews).
FUEL FILTER INSTALLATION
(1) Clean bottom of fuel filter base.
(2) Apply clean diesel fuel to new fuel filter gasket.
(3) Install and tighten filter to filter base. The bev-
eled part of the rubber gasket should be facing up
towards the filter base.
(4) Clean the inside of bowl with a soap and water
mixture before installation. Carefully clean any resi-
due between the two metal probes at the top of the
water±in±fuel sensor. Do not use chemical cleaners
as damage to the plastic bowl may result.
(5) Pour diesel fuel into the plastic bowl before
installing bowl to bottom of fuel filter. Do this to help
prevent air from entering fuel injection pump while
attempting to starting engine.
(6) Install filter bowl to bottom of filter.
(7) Install the electrical connectors at bottom of
bowl.
(8) Tighten the filter±to±mounting bracket nuts
(Fig. 29) to 28 N´m (250 in. lbs.) torque.
FUEL HEATER
If the fuel heater element needs replacement, the
plastic filter bowl assembly must be replaced. Refer
to Fuel Filter/Water Separator for information.
FUEL HEATER RELAY
The fuel heater relay is located in the PDC. For
the location of the relay within the PDC (Fig. 30),
refer to label on PDC cover.

the adapter tool (Fig. 46).
(10) Using a socket attached to the end of crank-
shaft, rotate the engine (counterÐclockwise as
viewed from front) until thedial indicator stops mov-
ing. This rotation is about 20É to 30É.
(11) S
et the dial indicator to 0 mm. Be sure the tip of
dial indicator is touching the tip inside the adapter tool.
(12) Very slowly rotate the crankshaft clockwise
until movement on dial indicator needle has stopped.

All high±pressure fuel lines are of the same length
and inside diameter. Correct high±pressure fuel line
usage and installation is critical to smooth engine
operation.
CAUTION: The high±pressure fuel lines must be
clamped securely in place in the holders. The lines
cannot contact each other or other components. Do
not attempt to weld high±pressure fuel lines or to
repair lines that are damaged. Only use the recom-
mended lines when replacement of high±pressure
fuel line is necessary.

CAUTION: Be sure that the high±pressure fuel lines
are installed in the same order that they were
removed. Prevent the injection pump delivery valve
holders (Fig. 58) from turning when removing or
installing high±pressure lines from injection pump.
