5. The vehicle engine should be inspected and
serviced according to the Engine Manufac-
turer's Operation And Maintenance Manuals.
a. Insure that exhaust is clear and clean with no
foreign materials. If water entry is suspected,
disconnect air tubes at the turbochargers to
check for water damage before attempting
startup.
b. Replace fuel filters. Fill filter cans with fresh
fuel for engine priming.
Have a new safety filter (secondary) filter element
on hand before removing old one. Do not keep
intake system open to atmosphere any longer
than absolutely necessary.
c. Remove and replace both the primary and
safety filter (secondary) elements in the air
cleaners. Check all intake lines between air
cleaners and engine. All clamps must be
tight.
d. The tubes in the precleaner section of the air
cleaner assembly should be inspected; all
tubes should be clear and clean. Use a light
to inspect the tubes. The light should be visi-
ble. If clogging is evident, the precleaner
must be cleaned. Clean the precleaner
according to instructions in Section C.
e. Drain and flush the engine cooling system.
Fill with coolant and inhibitors after checking
all lines, hoses and connections. Refer to
Section P, Lubrication and Service, for anti-
freeze recommendations. Radiator cores
must be clear of dirt and trash.
To prevent injuries, always release spring ten-
sion before replacing the fan belt.
f. Check and tighten engine fan drive belts,
and install a new belt set if necessary.
g. Check and tighten the engine mounts.
6. Inspect and service the transmission according
to the Transmission service manual.
NOTE: If a hydraulic pump or the engine is
inoperative, the dump body should be raised with a
crane so body holding devices can be installed.

a. Check all transmission electrical connections
for corrosion, cleanliness and tightness.
Check electrical cables for weathering, dam-
age and proper clamping.
b. Check drive lines for worn U-joints and
proper hardware torque.
c. Check the condition of the transmission
mounts.
7. If fuel was left in the tank, it must be removed.
Do not attempt to use old diesel fuel.
a. With the tank empty, remove inspection
plates and thoroughly check the interior of
the tank; clean if necessary to remove sedi-
ment and contamination. If the fuel was con-
taminated, the lines should be disconnected
and blown clear.
b. Check all fuel lines for deterioration or dam-
age. Replace lines as necessary.
c. Replace inspection covers, and install new
gaskets.
d. Fill the tank with specified diesel fuel.
e. Replace fuel filters.
Any operating fluid, such as hydraulic oil or
brake fluid escaping under pressure, can have
sufficient force to enter a person's body by pene-
trating the skin. Serious injury and possible
death may result if proper medical treatment by a
physician familiar with this injury is not received,
immediately.
8. The hydraulic tank should be drained. If oil is
not contaminated and is stored in clean contain-
ers, it may be reused if filtered through 3-micron
filter elements when being pumped back into
the tank. Do not attempt to use contaminated
hydraulic oil, especially if water entry into the
system is suspected.
NOTE: If filling is required, use clean hydraulic oil
only. Refer to the Lubrication chart in Section P,
Lubrication and Service, for proper oil specifications.
a. Replace hydraulic filter elements and clean
suction strainer elements. While suction
strainers are removed, inspect and clean the
interior of the tank thoroughly to remove all
sediment and foreign material.
b. Inspect all hydraulic lines for deterioration or
damage. Replace suspect lines - don't risk
hose ruptures or blow outs.
