PREVENTIVE MAINTENANCE
INSPECTION GUIDELINES
Follow the guidelines below when inspecting for cuts, fraying, extreme or
unusual wear of the webbing, damage to the buckle, retractor, hardware,
or for other factors. Damage to these areas indicate that belt system
replacement is necessary.
It is important to remember that any time a vehicle is involved in an
accident, the entire seatbelt 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. 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. The following points refer to the illustration
on page 270.
• 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.
• The shoulder web guide is the area where almost constant
movement of the seatbelt webbing occurs because of relative
movement between the seat and web.
• Inspect the seatbelt reel/retractor, which is mounted on the side
or rear of the seat, for damage. The retractor is the heart of the
occupant restraint system and can often be damaged if abused,
even unintentionally. Check operation to ensure that it is not locked
up and that it spools out and retracts webbing properly.
The KAB554B retractor is designed to automatically lock when the cab is
not level. The truck should be on level ground and the angle of the belt
relative to the seat needs to be correct to ensure the automatic lock does
not engage.
