Preventive Maintenance
Due to these factors, the three-point safety belt system
installed in your vehicle requires thorough inspection every
20,000 miles (32,000 km). If the vehicle is exposed to severe
environmental or working conditions, more frequent inspections
may be necessary.
Any seat belt system that shows cuts, fraying, extreme or
unusual wear, significant discoloration due to UV (ultraviolet)
exposure, abrasion to the seat belt webbing, or damage to
the buckle, latch plate, retractor hardware or any other obvious
problem should be replaced immediately, regardless of
mileage.
WARNING! It is important to remember that any
time a vehicle is involved in an accident, the
entire seat belt system must be replaced. Unexposed
damage caused by the stress of an accident
could prevent the system from functioning
properly the next time it is needed, which could
result in severe injury or even death.
Inspection Guidelines
Follow these guidelines when inspecting for “cuts, fraying,
extreme or unusual wear of the webbing, and damage to the
buckle, retractor, hardware, or other factors.” Damage to
Cab Maintenance
these areas indicates that belt system replacement is necessary.
WARNING! Replace the entire belt system
(retractor and buckle side) if replacement of any
one part is necessary. Unexposed damage to
one or more components could prevent the system
from functioning properly the next time it is
needed, which could result in severe injury or
even death.
1. Check the web wear in the system. The webbing must be
closely examined to determine if it is coming into contact
with any sharp or rough surfaces on the seat or other
parts of the cab interior. These areas are typical places
where the web will experience cutting or abrasion. Cuts,
fraying, or excessive wear would indicate the need for
replacement of the seat belt system.
2. The pillar web guide (D-loop) is the area where almost
constant movement of the seat belt webbing occurs
because of relative movement between the seat and
cab.
3. Check the Komfort-Lok Latch for cracks or possible damage
and check for proper operation.
