CAB
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
these areas indicates that belt system
replacement is necessary.
WARNING!
Replace the entire belt system (re-
tractor and buckle side) if replace-
ment of any one part is necessary.
Unexposed damage to one or more
components could prevent the sys-
tem from functioning properly the
next time it is needed.
Failure to
comply may result in death or per-
sonal injury.
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 Comfort Clip for cracks
or possible damage and check for
proper operation.
4. Check buckle and latch for proper
operation and to determine if
latch plate is worn, deformed, or
damaged.
5. Inspect the retractor web storage
device, which is mounted on the
floor of the vehicle, 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.
6. If tethers are used, be sure they
are properly attached to the
seat and, if adjustable, that they
are adjusted in accordance with
installation instructions. Tethers
must also be inspected for web
wear and proper tightness of
mounting hardware.
7. Mounting hardware should be
evaluated for corrosion, and for
tightness of bolts and nuts.
8. Check web in areas exposed to
ultraviolet rays from the sun. If the
color of the web in these areas is
gray to light brown, the physical
strength of the web may have
deteriorated due to exposure to
