Performing regular scheduled maintenance ensures reliable operation and
optimum service life of the various chassis components. Completed maintenance
brings peace of mind knowing the various components have received proper service.
Failure to follow maintenance guidelines, or perform scheduled maintenance, results
in inefficient operation, premature component wear or component failure resulting in
breakdown.
Maintenance schedules are usually performed at certain mile or time intervals.
When performing high level procedures, lower level service should also be performed.
Maintenance procedures for chassis components are located in the chassis section
NOTE: Maintenance schedules are based on normal operating
conditions and use. Operating under unusual or adverse condition
shortens service intervals.
NOTE: Engine and transmission service intervals are listed in
their respective manuals.
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 Specification), API (American
Petroleum Institute) or by other recognized and accepted organizations. The correct
lubricant type with an approved specific rating must be used whenever applying,
changing or adding any lubricant. When purchasing lubricants for a specific
application be sure the label affirms the type of lubricant required with the tested
rating by the term "meets or exceeds" in accordance with the manufacturer
specifications.
Lubricants are manufactured in many forms for a variety of applications. There
are many different oil and grease consistencies each with a designed application.
To properly select a particular type of lubricant for a specific application, the
component must be evaluated. Component stress loads, ambient temperature,
working temperature and environmental exposure are just a few of the variables to
consider. Select the proper lubricant for its intended application. As an example:
selecting high viscosity grease to lubricate a lock cylinder results in sluggish lock
cylinder operation especially in a cool environment. Conversely, using graphite to
lubricate a component that is under extreme temperature and load will result in
component failure.
