CHASSIS INFORMATION — 10
Conversely, using graphite to lubricate a
component that is under extreme temperature
and load will result in component failure.
Grease ratings and their base compounds are
especially important when selecting a lubricant
type for an intended application. Some grease
compounds are manufactured for multi-use
application. These are acceptable if the grease
rating is in accordance with the manufacturer’s
recommended lubricant type and rating.
Lubricants:
Many chassis components require lubrication.
The types of lubricants used will vary with the
application of the component. A component
may fail prematurely due to lack of lubrication
or from using an incorrect lubricant type. The
component manufacturer usually recommends
a particular type of lubricant with a minimum
approval rating. Most lubricants are tested under
strict guidelines set by the
ASTM (American
Society for Testing and Materials)
. The
NLGI
(National Lubricating Grease Institute)
helps
disperse information to the grease production
industry. Grease containers usually have
an approval rating by the
SAE (Society of
Automotive Engineers)
,
Mil Spec (Military
Speci
fi
cation)
,
API (American Petroleum
Institute)
or by other recognized and accepted
organizations. The correct lubricant type with an
approved speci
fi
c rating must be used whenever
applying, changing or adding any lubricant.
When purchasing lubricants for a speci
fi
c
application be sure the label af
fi
rms the type of
lubricant required with the tested rating by the
term “meets or exceeds” in accordance with the
manufacturer speci
fi
cations.
Lubricating greases are made from different
base compounds giving the grease different
lubricating consistencies, properties and
maximum operating temperatures. Most
containers list the base compound and
maximum operating temperature usually listed
as melting point or drip point. Lubricating
components, such as brake component for
example, require a high temperature special
base compound grease. Lubricating this type of
component with other than speci
fi
ed grease type
will result in inadequate lubricating qualities
resulting in component malfunction or failure.
INSPECTION:
When performing any scheduled
maintenance, inspect the area around
where you are working. For example,
changing the oil, look at the rear
differential. Inspect for visual signs of
fluid leaks.
Most
fl
uids and lubricants have a distinct
odor, which can be used to detect early signs of
trouble. Generally, odors are most detectable
soon after parking. Unusual sounds are another
method of detecting a problem early. There are
many types of sounds that are normal, such
as the cyclic purging of the air dryer. Become
familiar with the different sounds. If something
sounds odd, smells peculiar or looks unusual,
investigate the situation.
Greasing:
Thoroughly clean all Zerk grease
fi
ttings
before applying new lubricant. Keep paper
towels or disposable rags handy when greasing.
When lubricating items such as drive shafts
and steer axle components, continued grease
application is generally required until new
grease appears at exit points.
Some items use sealed boots around the
component to prevent moisture intrusion. When
greasing these types of components, care must
be given to prevent excess lubricant pressure
from rupturing the seal.
WARNING:
Always chock wheels before going
underneath the motorhome.
WARNING:
Never place yourself under motorhome
without first properly blocking frame
(jackstands) from coming down in case
of rapid deflation of air system.
Brake actuating components require
lubrication to keep the actuating components
freely operating. Avoid contaminating brake
linings with lubricant. Particular care and
attention to details should be taken when
lubricating brake actuating components. Wheel
removal may be necessary to gain access the
grease
fi
ttings.
NOTE:
Suspension, steering, brake and
drivetrain components are lubricated at
the factory using Texaco Starplex NLGI
2 Lithium Soap based grease.
