5.
Inspect the outboard side of all wheel hubs and
the hub oil seal area on the inboard side of each
wheel for signs of oil leakage. If any oil is found
on wheel and tire or brake components, remove
the vehicle from service until the leak has been
fixed.
If needed, fill the hubs to the level indicated on
the hub cap. See
Group 35
of the
New Casca-
dia Maintenance Manual
for recommended lubri-
cants.
6.
Check that mud flaps are undamaged and hang
10 inches (25.4 cm) or less from the ground.
Saddle Tank Areas Inspection
WARNING
When draining the air reservoir, do not look into
the air jets or direct them toward anyone. Dirt or
sludge particles may be in the airstream and
could cause injury.
NOTICE
If the water drained from the air reservoirs is
cloudy or oily, it may indicate a problem with the
compressor. If oil is allowed to contaminate the
air dryer, it will not remove the water from the air
brake system, which could adversely affect brak-
ing.
1.
Drain the brake system air reservoirs (reservoirs
without automatic drain valves only).
WARNING
Never operate the engine with the fuel tank shut-
off valves partially closed. This could damage the
fuel pump, causing sudden loss of engine power,
possibly resulting in serious personal injury due
to reduced vehicle control.
2.
Ensure fuel tanks are secured to their mounting
brackets and that the mounting brackets are se-
cured to the frame.
If equipped with fuel tank shutoff valves, be sure
the valves are fully open.
3.
Inspect visible frame rails for missing bolts, shiny
areas, or rust streaks. Check all visible cross-
members for damage or signs of looseness.
4.
Inspect visible components of the exhaust sys-
tem to ensure connections are tight.
Inspect upstream of the aftertreatment device
(ATD), if equipped, for cracking or signs of leaks,
such as soot trails. Inspect downstream of the
ATD for signs of exhaust leaks, such as blister-
ing or warping of nearby components.
Engine Compartment Inspection
1.
Check the ground underneath the engine for fuel,
oil, or coolant leaks.
2.
Inspect the air intake system for leaks or dam-
age.
NOTICE
Failure to maintain a sealed air intake system
could allow the entry of dirt and contaminants
into the engine. This could adversely affect en-
gine performance and result in engine damage.
2.1
Push the reset button on the air intake
restriction indicator, if equipped.
NOTE: The air intake restriction indicator
may be located on the air intake or the
dash.
2.2
Check the air intake duct from the air
cleaner to the engine intake. Make sure
the duct components are secure and air-
tight.
3.
Check the engine oil level.
NOTICE
Operating the engine with the oil level below the
minimum fill (or "add") mark or above the maxi-
mum fill (or "full") mark could result in engine
damage.
3.1
Check the oil level with the vehicle parked
on a level surface. See the engine manu-
facturer’s guidelines for engine shutdown
time requirements prior to checking the oil
level.
IMPORTANT: Use CJ-4 engine oil with less
than 1% sulfated ash. Failure to use CJ-4 oil
may void the warranty on emission after-
treatment components.
3.2
If the oil level is at or below the minimum
fill (or "add") mark on the dipstick, add
enough oil to maintain the level between
